Best Thermostat Repair in Tampa FL

I contacted this company recently to diagnose and fix my AC. The technician arrived within the requested time slot, which I appreciated, and I also liked how they send a text to let you know when the technician is en route. Our AC issue turned out to be minor and was quickly resolved.

Incredibly happy customer!! Not only did they provide the BEST option out of 4 quotes I obtained. They took time to answer all my questions and teach me about what I was buying so I could make a truly informed decision. I didn't feel like I was being SOLD I feel like they were actually helping me which showed they CARE.

They further proved they cared by making sure everything worked and was programmed to my satisfaction. I couldn't get the WiFi feature to work. I attempted to contact customer service on the device to fix myself but couldn't. Instead of sending me to instructions or back to customer service they sent out one of their techs who had some knowledge and success on IT stuff.  It took several attempts but they stayed and troubleshot until they got it working!

Excellent customer service. GREAT TEAM! Even if you have to pay a tad bit more (which I didn't cause they had the best deal)... it's worth it! Nothing beats great customer service. Found out they do plumbing too. They will definitely be my one stop shop for Heating, Air, & Plumbing because I know I can trust them. Grateful!

These guys are the worst in the business.

Came out quoting how honest they are and in the end, switched up wires on my unit to make it seem broken. I had very reputable A/C Company come out for a second opinion and he verified the wires were misplaced. The Service Manager Tito lied to misadvising that his techs do no inspect wires on a maintenance call. I saw the service tech take off the hard start capacitor that wires were switched up on while Northside was at my house. Along with that, the hard start capacitor was the piece that had the wires switch.
The second company I had come out told me they hear about Northside doing this to a lot of people and hate that they give the industry a bad rep.

The service tech wouldn't even look me in the eye after the call, and snatched my check up off the table like the thieves they are.
Don't trust these guys, they're slimy no good cheaters.

I called bc my AC went out on a Friday night and my reg AC guys don't work on the weekend. I was told there was an $89 fee to come out on weekends. No prob.  The tech showed up and determined the module was shot but luckily he had one on the truck. He informed me that he dumpster dives for parts, and he had a used module that would get the system up and running. 20 mins later my system was blowing cool. But when he handed me the bill I was shocked. $384. for a part he got out of a dumpster which took about 10 mins to install! When I questioned it I was told the computer sets the price. Wait what? He also informed me they have the highest prices in town. Caveat Emptor!

We just purchased a townhouse with  a A/C unit that is over 10 years old.  I called RJ Kielty on a referral from a friend.  I called for service and was scheduled for a noon arrival time. The serviceman, Kyle, called at 9:30 to say he was on his way. WOW a company that turns up early, instead of making the customer wait.  Kyle serviced/tuned up my system all the while wearing booties so as to not track dirt in the house.  After completing the service, he proceeded to explain what he found. At no time did I feel pressured to buy any product or service that was not needed.  Kyle was professional, knowledgeable, and respectful.. When service and eventually a new A/C unit is needed RJ Kielty is the first company I will call.

Way to GO JAY!!!!

Been dealing with Cornerstone for years. I have three houses in Plantation Palms that they service for me. They used to service my old A/C units and then they gave me a great deal and I replaced all three units.
I just had a problem with one unit not cooling. It was in a house that I have a tenant in with small children.  The part was not going to be available for about 5 days. Jay, the A/C Service Manager helped me out big time. He was leaving for the day so he told me he would pick up two window air conditioners and personally install them for my tenant, all on his way home!
That's what I call going over and above to help a customer.
Thank you Jay!  Really appreciated your outstanding effort.
