Takes the time to explain his work in detail,

Found Sal almost 10 years ago after a service call with a BIG name service provider, which I made "for all the right reasons", amounted to a $600 charge for adding some coolant and changing out a contact. I've never looked back. Really appreciate the fact that he takes the time to explain his work in detail, even if much of it is over my head. He recently installed a new high-efficiency Lennox system in my townhouse, and quite honestly, even after having some history with him and his company, I anticipated - as is prone to happen in the service industry - that he would end up charging me more than what he originally estimated. Nope. I truly believe he's a man of integrity. He is more responsive than any service tech I've ever worked with. His prices are reasonable. The new system looks and runs great. Hoping he never retires, because I feel like I have found "my guy" for all things HVAC. Highly recommend!

Look no further, ladies and gents!

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!

Quality of work is above any other contractor!

Pinnacle's response time and quality of work is above any other contractor! Always out the same day when emergencies have arisen. I have used them in several residences and also in commercial locations, and refer them constantly. High quality of work matches their fair pricing.

After being out of town for a couple of days and having coming home to no heat we called Sal 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.!

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

Sal and company are awesome. Had some issues with our furnace kicking off at what seemed to be random intervals. Sal and his coworker came by and with a few minutes diagnosed the issue and fixed it for us. He also took care of us on price as he always does. Pinnacle is a fair and honest company! Recommend them all the way!!!

Sal came out quickly to fix our air conditioner problem. He showed me the proper way to change the filter. He was very much knowledgeable on our Lennox unit. He quickly diagnosed and fixed our problem at a very fair price. I would highly recommend him to all friends and family.

I called Sal he came within 45 minutes. He accessed 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 him enough thank you Sal.

Thank you Pinnacle, Sal, and your helper today for replacing our squirrel cage/motor for our furnace/air conditioner and doing so in such short notice, during a holiday week and one of the very hot & humid, dog-days of summer! The expertise of your staff to hear and know exactly what was wrong within minutes of arriving at our home, fixing the issue so quickly (within 3.5 hours), and taking the time to explain the whole process made my day. I am very pleased and excited that we are able to have a cool house once more and to have Jacob (4 year old) and Jessa Lee (9 month old) back in their home tonight! I will definitely recommend your company to our neighbors, family and friends. The Estrada Family

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 their service was fast and flawless.

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 Sal at around 9:30 PM and he quoted me a price to replace the 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 and Sal came out and 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 Sal 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 Sal out to repair a couple of other things he identified while repairing the water heater. I highly recommend Pinnacle for any HVAC needs anyone may have!

Called Sal 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 Sal 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 Sal!

Great Service!!

Great Service - all-around solid company by AC repair- Pinnacle does a superior job. The client service and accommodation was outstanding. Sal was able to come out to repair my AC unit on short notice and provided a very thorough and professional opinion and repair. He took pictures of the AC unit and offered advice on how to get optimal efficiency. I would definitely use Sal/Pinnacle in the future. Thanks for your help.

Pinnacle will spend the time to make it right!

Fantastic Overall Offering & Customer Service - Pinnacle will spend the time to make it right! I was having issues with my AC throughout the summer - I connected with Pinnacle during the winter. They performed a very thorough Heating check-up for me, so I called him to get advice on the resolution to the issue (Thermostat set at 70, Space showing 79). He advised that, while it could be a leak in the coil, he would want to check it out to make a firm determination. He was on-site 24 hours later, checked the entire system out, and was correct in his determination. Sal spent an hour walking me through my options, and helped me choose a 16 SEER Trane Condensing unit and cased coil, based upon a desired payback and how important it was for my system to run effectively. Sal arranged to have the units delivered on Friday evening, and was back on Sunday to complete the project -and the pricing was extremely competitive. I highly recommend Pinnacle for all HVAC needs!

A great BIG thank you to Sal and his crew for the great job they did converting my furnace from a down draft to an up draft. 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.

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!!

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. Sal and his son, Sam, not 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 Sal and Sam! I will recommend you to anyone who needs AC service!
