Testimonials

“After being out of town for a couple of days and having coming home to no heat we called Pinnacle HVAC and he was out within in a couple of hours. He got my furnace going quickly and fixed my humidifier as well. He was very reasonably priced as well especially since he came out on a Friday night definitely after hours. He explained everything to me and made sure I understood how to perform the maintenance needed. I will definitely have them out before summer to service the AC. Great service that I will recommend to others. My wife and 7 month old son were very happy Pinnacle came out!”

- Bret, Lockport

“We were in need of a new AC unit for the start of spring/summer. We had several companies come out, inspect our home, and give us quotes on mid-top level AC units. When we met the technician you just got a sense of people working hard, giving you a quality product, and not ripping you off. Pinnacle is an OUTSTANDING company that goes above and beyond customer care. They are truly passionate about what service they are providing for your home and what you will get in return. Both our boys have seasonal allergies, They were incredibly knowledgeable about HEPA systems and filters that would help reduce allergens in our home. We would highly recommend Pinnacle to anyone looking for a quality product, at a competitive price, and with great customer service.”

“Our first service call was a few years ago on New Years Eve when our furnace went out. We called Pinnacle Heating and Cooling and they came out right away to fix our unit. He seemed genuinely concerned and fixed our unit not caring about the time and date. He was professional and we felt that his charge was fair. We recently needed another heat related matter resolved and that was getting our pool heater to work. We remembered Pinnacle and the excellent service we received from him and decided to call him about the pool heater. He again came out to our home and fixed the heater. It was a simple fix and he only charged us a service call. We truly appreciate Pinnacle Heating and Cooling and the skill and professionalism this company represents. When we replace our heating and cooling units, we will be calling Pinnacle HVAC.”

“I called Pinnacle. They returned my call in about 30 minutes and were out at my house within 24 hours for a non-emergency call. They were on time for the appointment, clean, courteous and professional. They were reasonably priced and took a lot of time explaining what they thought the problem was and gave some give advice on how to try to fix it without spending more money than necessary. I would DEFINITELY call them again!!!”

- Joanne D., Homer Glen

“I was told by a different heating & cooling company that my Freon is leaking & that I needed to purchase a new AC unit. So in my search for pricing a new unit, I called Pinnacle. They came out the next day, ran some diagnostics & found that the Freon was low, but nothing that warranted my replacing the entire AC unit.They did what needed to be done and saved me about $3000!They also took a look at my furnace & informed me that I am only using 1/2 of it’s capabilities. It’s a 2 stage furnace & but is set up for one-stage operation, so I’m going to have them come out in the fall to tune up the furnace & install a 2 stage thermostat which will make the house warmer in the winter & run the furnace more efficiently. These guys are GREAT! I would (and will) recommend them to anyone & everyone.Thanks Pinnacle!”

- Don S., Homer Glen

“Pinnacle made it out the same day I called him at a time that was convenient me. They fixed the problem with my AC, but I was more impressed with his willingness to explain to me in detail, the problem and different parts of the AC unit and what they did. What he charged me was very reasonable and I did not have to buy a new AC unit. I highly recommend Pinnacle.”

- Rich, Palos Park

“I just want to say, Pinnacle is a class act, came out on a Sunday and took the time to explain what was going on and walked me through corrective action. My air conditioner went down and they responded very quickly to my call and didn’t try and push unnecessary repairs on me.I have a little girl with asthma and he took the time to make sure when assembling my blower fan that it was clean and free of all dust and particles. Great service, really fair rates and I am recommending him to all my community.He will be servicing my house from now on. Top notch guy and service!”

- Joe C., Woodridge

“I called Pinnacle on Tuesday June 12, the gentleman told me he happened to be in the neighborhood. Not even an hour later the crew is at my front door ready to repair my outside AC unit. The price was fair and there service was fast and flawless.”

- Jose O., Lockport

“I called Pinnacle and they came within 45 minutes. The technician assessed the problem right away. He put a new connector into my air conditioning unit because it was broken and then he cleaned my furnace. He was a good guy he showed me how to put the filter in. What a nice man, he was a life savior. I will definitely have him out again. I can’t thank them enough. Thank you Pinnacle.”

- Victoria, Lockport

“Thank you Pinnacle for the quick service. I could not be happier. It was nice to have someone return your call right away and to not shy away from a job that was under warranty from another contractor. Thanks again for your quick, affordable and professional service!”

- Kim R., Lemont

“Sal and his guys did a great job. Their attention to detail is unmatched by any other HVAC companies I have dealt with. They provided a link with detailed pictures of the install of new furnace and AC unit. They are highly recommended.”

“We had a great experience with Pinnacle. They were responsive and thorough. The tech quickly diagnosed and fixed our problem at a very fair price. We will not hesitate to contact them again for our future needs.”

- Wolf Family, Homer Glen

“Pinnacle gets an A+ from me. They have a passion for the quality of the job they do; very professional outfit. My brother referred them to me. I got a new ac/furnace installed at a very affordable price. I like when the installer calls u & asks how everything is running,not when u have to call them with problems.Thanks again Pinnacle.”

- Nick S., Homer Glen

“Pinnacle HVAC came out quickly to fix our air conditioner problem. He showed me the proper way to change the filter. He was very knowledgeable about our Lennox unit. The tech quickly diagnosed and fixed our problem at a very fair price. I would highly recommend him to all friends and family.”

- Sharon K., Lockport

“Pinnacle HVAC came to my home in the same day I called when our air-conditioning went out on a 95 degree day! The tech was very pleasant and knowledgeable, and I would highly recommend anyone to call Pinnacle for great service! Thanks!”

- Joe, Lemont

“Called Pinnacle tonight around 8 pm because my furnace was only blowing cold air and its supposed to get down to 5 degrees. He happened to be at the store a few blocks away and was over within 15 min. Got my furnace working again in a few minutes (needed a quick cleaning to work for a few days) and wouldn’t take any payment just said "be sure to keep me in mind for future repairs and when you get this cleaned. I just didn’t want you to go through this night with no heat." I will be having Pinnacle come back next week to clean it completely and will recommend him any time. Nice to know there are still good people out there that are concerned about their clients, not just concerned about making money. Thanks Pinnacle!”

- Alex, Lockport

“A couple weeks ago our water heater went out on a Friday night. I googled for a water heater repair company in our area, and Pinnacle was one of the first that came up. I called and talked to the technician at around 9:30 PM and he quoted me a price to replace the draft motor on the water heater and said he’d come by the following morning. The next morning, he came out and had everything repaired by noon. Later that night, our water heater was not working again they discovered that our chimney had a blockage due to a poor job by our home builder, and he even got up on the roof and corrected that problem as well. We have had no issues since, and they even called back to confirm everything was good the next morning. I couldn’t be more pleased with the service I received, and will probably have them out to repair a couple of other things they identified while repairing the water heater. I highly recommend Pinnacle for any HVAC needs anyone may have!”

- Will S., Lockport

“Great Service!! We found Pinnacle through google on a Sunday afternoon after noticing that our air conditioning was not working well. They came out within an hour of our call. Very professional and very detailed. He showed us everything that he did and even repaired the PVC pipe that was improperly installed. (we had no idea).I would highly recommend Pinnacle to anyone who needs their air/heat serviced. Very fair priced, it was actually lower than what we thought. Professional, friendly, great work and fair priced, what more can you ask for! Thank you!!”

- Millisa & Warren, Lockport

“Great prices, excellent service. Looked up a local AC service on the internet and found Pinnacle at the number one spot. Our fan wasn’t working on our air conditioning unit and I knew it needed fixing, especially in the middle of a heatwave! I didn’t think anyone would have been out right away. I also didn’t think it was going to be cheap to have someone come out right away either. I was wrong on both counts. The technot only came out within the hour I called, they fixed us up nice and quick and at a fair price. The house is now a nice, cool temperature and I can sleep better at night, knowing I got a great deal for their service. I got exactly what I was looking for. Best part of the deal was that we love to support mom and pop shops. We were more than thrilled to know that Pinnacle is a family owned business. Thank you Pinnacle! I will recommend you to anyone who needs AC service!”

- Chris & Rick C., Lockport

“My furnace was out. I made many phone calls and no one wanted to help me. I called Sal at Pinnnacle even though he had a booked up day he made sure he stopped and fixed our furnace Many thanks to Sal and his son Such honest and compassionate people I felt like I was being taken care of by family Thank you Sal. I would highly recommend Pinnacle for all your HVAC needs.”

- Laura

“Highly Recommend. My husband and I purchased our home and two days later on a 90+ degree day our air for the upstairs stopped working. We called Pinnacle and he was out the next day which happened to be a Saturday. They spent five hours going up and down our stairs to find the problem. They were very nice and explanatory. Problem was a defective TXV. Would highly recommend their service!”

- Veronica, Manhattan, IL

“These Guys are excellent!!! They gave me same day service, which was greatly appreciated since my ac was out over the holiday weekend. They walked me thru the process of what can cause the issues I was having and what to he and us as homeowners should be looking for. The techs thinking out loud truly helps people understand the logic and process of trouble shooting while educating you as a homeowner!! Finally after years of looking for a new hvac person to service my mechanicals I’ve finally found one!! I find Pinnacle HVAC to be an honest company with integrity and very reasonable pricing!! Just recommended Pinnacle to my mother!”

- Art, Lockport

“Excellent Service! My furnace was acting up and would stop working after a few hours (no heat). I changed the thermostat since it was old however this did not resolve my problem. Bad luck have it, this took place during the coldest weekends thus far. I contacted Pinnacle Heating & Cooling. I gave them a description of my heating problem and he provide me with some suggestions I could try; thinking I had installed the thermostat incorrectly. I did as he suggested but no luck, so I had him come out regardless. This alone was great service over the phone! When he arrived, he resolved the issue and fixed my furnace humidifier which I did not realize was not working. Pinnacle’s customer service was great; they are extremely knowledgeable as not only did he repair both my furnace and humidifier but he explained everything about my furnace to me. I highly recommend Pinnacle Heating & Cooling, their service was great and my family is warm for the winter.”

- Jose, Orland Park

“I just can not say enough about this company, they are truly the very best in what they do. Not only were they on time and here when they said they were going to be, but they went well above and beyond the service that I called them out for in the first place. They took the time to explain and even teach me things I was not aware of, that being a homeowner, should know. With a little humor thrown in. There should not be a doubt in your mind when you call Pinnacle for getting the job done correctly and with quality”

- Shannon F., Lockport

“I can’t say enough good things about Pinnacle! After our AC went out, just as summer is starting of course, I searched online for a good AC guy in the area. After reading tons of 5 star reviews, I decided to give Pinnacle a call. Assuming that I would have to wait a few days to get someone out to look at it, I was pleasantly surprised that they were able to come the same day (a Saturday none the less!) Not only did they show up just hours after I placed the call, they got my AC fixed and running as good as new! they did such an excellent, thorough job (in 95 degree heat), and definitely gave me my first lesson in heating and air conditioning. I can’t thank you both enough! Its a great feeling to have someone who is honest with you and who treats you as family. I look forward to working with you again in the future!”

- Margaret S., Lockport

“I found Pinnacle online and it received 5 stars from customers so I decided to call them. They came out to look at our air conditioner and they were there for almost an hour trying to fix it but to no avail! We needed a new one. The Tech was very upfront with us with what we needed including the cost. They replaced our air conditioner plus all the duct work that needed to be done a few days later and did a great job! My husband and I highly recommend Pinnacle because they were very honest and reasonable priced. I wish I knew about them 2 years ago when our furnace went out! Thank you Pinnacle!”

- Diane H., Joliet

“Can not say enough great things about this company. Found them in the local phone book and decided to give them a try. Both times they fixed my problems that were very difficult to find. They stuck with it. Anyone else would have told me you need a new furnace”

- Jodie H., Lemont

“A+++ is the grade given to the guys at Pinnacle Heating and Cooling. If you are in need of repair or replacement, this is the company for you; look no further! From the same day service call to a complete installation of a new energy efficient furnace and air conditioner a few days later, the entire process was painless; I barely knew they were in the house. Pinnacle gave me several quotes, from repair to replacement and not once was there any pressure to proceed in a certain direction. They made sure I had all the information necessary to make an informed decision. I am so happy to have found Pinnacle. We also had a gas leak on the line to our water heater that we were unaware of; the Tech discovered this and changed the connection at no additional charge…incredible! Do not hesitate to contact Pinnacle Heating and Cooling, you will not be disappointed. The cleanup was amazing…our unfinished basement was in better shape than when they arrived…LOL. Thank you Pinnacle!”

-  Patty C., Homer Glen

“A great BIG thank you to Pinnacle HVAC and the crew for the great job they did converting my furnace from a downflow to an upflow. Installing ductwork in a small attic was not an easy task. Their pricing, workmanship and concern for satisfaction was excellent. I would recommend them to anyone”

- Jackie B., Lockport

“Needed a humidifier in my new home and called Pinnacle. Not only was he very knowledgeable about all my HVAC equipment he was very Professional and reasonably priced. He gave me deailed instructions for operation of my new humidifer and made sure I was happy with his installation.If you need heating or air conditioning service call Pinnacle HVAC!”

- Jim, Frankfort

“We were in the market for a new furnace and air conditioner. Sal was recommended to us by a family member. After talking to Sal, we knew we would be in good hands. The guys installed a new furnace and air conditioner in our house and we couldn’t be happier with the final product. Sal and company took great care of us and we would certainly recommend to others looking for an all-around quality experience.”

-  Luis S.

“Pinnacle did a great job take it from a General Contractor for over 30 years. I have been a General Contractor in the Chicago and Suburban area for over 30 years. When my furnace and A/C went out on Monday I called Pinnacle. I had never used them before. Being from Homer Glen, IL I wanted to use someone in the area so I didn’t use my usual sub-contractor. They answered my call immediately and got right over to inspect the problem. By Wednesday he had the new unit installed and running. I found him to be knowledgeable and extremely customer service oriented with very competitive pricing. I have some other work to be done in the spring and I will definitely use Pinnacle Heating and Cooling again. In fact I have added them to my business’ preferred vendors list as well. Thanks Pinnacle.”

- Mike O., Homer Glen

“I have a 60 year old house, with a 31 year old HVAC system. Pinnacle was one of the many bids I pursued. I ultimately chose them for their professionalism, timeliness, courtesy & knowledge of their products (and their incredibly competitive pricing). After settling on a quote, They were literally out at 7am the next morning to install my system. They were done in one day, & I have never been happier with a furnace & a/c. I am completely satisfied with the Trane system, & have lowered my utility costs significantly. This is by far the most efficient system I have ever come across. The team was meticulous, didn’t mind me hanging around and asking questions during the install, & have done follow-up calls with me, just to make sure I was satisfied. I would recommend Pinnacle to ANYONE looking to upgrade their own system. Thanks again Pinnacle!”

- Kim K., New Lenox

“Our neighbors recommended Pinnacle to us when once of our AC units went out during the heat of the summer. Both AC unit and furnaces were replaced in one day at our convenience. The team was thorough and professional. Pinnacle really cares about the quality of their work and customer satisfaction. Great to do business with!”

- Tim & Gia O., Homer Glen

“The experts at Pinnacle Heating & Cooling were top professionals throughout the entire process, from quote to follow up. The team took the time to do things right. They evaluated the heat load, the size and position of the house and even the location of the current thermostat. They took the time to walk me through the whole process to explain what he recommended and why, then asked if I had any questions or concerns. Pinnacle Heating & Cooling made me feel like a valued customer by not rushing the job and even doing a next day, next week and a one month follow up to see if I had any issues or concerns. I am 100% satisfied with Pinnacle Heating & Cooling and with my new A/C system. I will continue to be their customer for all my heating and cooling needs.”

- Kevin, Plainfield

“Sal and Sam are shining examples of what HVAC contractors should be; I work in the industry on the commercial sales side, so I hold technicians to a high standard with their work, professionalism and ability to problem solve - Pinnacle has bested any other group I've hired in the past, so I only use Sal and Sam for my work (it's like finding a mechanic for your car that loves your car as much as you do!) I have recommended Pinnacle to not only customers of mine needing residential service/replacement, but also to my parents for their HVAC needs. Look no further, ladies and gents, your optimal choice for HVAC contractor is here! Thanks, Sal and Sam, for all the work you've done for me and my family throughout the years!”

- Allan W.

“Sal was excellent in his service and expertise. He and his crew provided and timely, reliable, and fair quote for service. They performed their work promptly and professionally. Sal called for follow up and arrived at the house to ensure the work held up properly. Sal provides a friendly professional service that I will rely on for all my HVAC needs.”

- Tavis S.

“Real customer service still exists in the form of Pinnacle HVAC! They had come to quote me on a new 1st floor AC/Furnace and discovered that my 2nd floor unit was wired completely wrong by the last HVAC company! Not only did they give me the most competitive quote but they discovered problems I didn’t even ask them to look for. It was really a pleasant experience from start to finish. They responded to my questions promptly, emailed me quotes (not some scribble on carbon paper), installed my system in a day and followed up with us after it was done. Their communication is excellent which is huge when you’re spending this kind of money. In the end they saved me literally thousands of dollars while giving the best customer service I’ve seen in any company – HVAC or otherwise. Thank you Pinnacle!”

“Great work!! Sal was friendly, knowledgeable, and very reasonably priced.”

- Joe D.

“Sal is always punctual, thorough, personable, and goes the extra mile to prevent future breakdowns from developing. I used many different firms over the years until I found Pinnacle, and now I would not consider anyone else. He has serviced our a/c and furnace for years, and I have called on him to service my mom's home, and recommended his service to everyone in my family. There is nobody better.”

- Mark D.

“Knowledgeable. Courteous and responsible. Arrives when stated. Trustworthy. Reasonably priced. Defiantly using again!”

- Lynn V.

“Pinnacle saved my furnace from an unnecessary extinction and saved me a lot of money! I was so angry when I had a perfectly good furnace looked at for preventative maintenance by a large conglomerate, only to have it stop working less than 2 weeks later. I was then charge for their diagnoses that I need a new furnace and given a price of fixing my old one close to the price of purchasing a new one. Luckily I called Pinnacle for a second opinion.They quickly came out, knowing I was without heat and the temperature in the teens. Although there seemed to be multiple problems, they stuck with solving the root problem. No new furnace was necessary at this time, there is still years left in mine. Pinnacle’s fix price was much less than the conglomerate’s price and it was nice that they took the time to explain everything to me. Pinnacle is my contact and repeated to anyone who asks.”

- Annie - Orland Hills, IL

“I was on the verge of closing on the sale of my house, and upon inspection the buyers wanted a few repairs done. The problem is I had limited time to get them done. I read reviews online and decided to give Pinnacle a call. GREAT CHOICE! Sal came out to my house the very next day, went through our HVAC system and made the repairs necessary to close on my house on time. The invoice was detailed, the customer service and follow up after repair was all first class. I know most customers leave reviews when unhappy, but I will be the first to tell you this company is a 10!”

- Dave P., Homer Glen

“Phenomenal Service! My 20+ year old furnace quit working. Pinnacle answered my call and had a service tech out within hours. With such an old furnace , anything could have gone wrong. Their honest technician immediately diagnosed the minor problem and fixed it quickly and quite reasonably. He even got my humidifier working properly in minutes. The tech explained everything and informed me on proper maintenance. I highly recommend their services.”

- Denise B., Lockport

“Quality service, quick response, fair price. Anything else to ask for? They stayed in my house till very late evening – I called late and they came same day – furnace was fixed. Whatever I needed was done – and some extra too… Service worthy of recommendation.”
