What Our Customers Say
Real Google reviews from our customers, shown word for word.
John is fantastic. He has handled the HVAC at my place for over a year now - helps with maintenance and repairs. He is very kind, timely and fast! Always reasonable with solutions. I feel at peace knowing he can help if I have any issue.
★★★★★
This is why we love dealing with Smart for all our AC needs. First, it's because of our wonderful technician Johnny, who is the most reliable, honest, nicest technician we have ever had!! He is always on time and very clean and courteous, and smart! Every time I call, you are always able to fit us in, at our convenience, and you have the best service plan in the industry! Thank you so much!! Pat and Steven
★★★★★
We had our entire HVAC system replaced last year. From the handler, to the ductwork and insulation. They were great. They came out fast and got the work done in 2 days! We just had our unit go out and John was out same day. He was extremely helpful and honest. We weren't sure why the system went down but he also provided tips to help make sure we are using the system optimally which can help prevent odd system failures. I can't recommend them enough!
★★★★★
Our a/c went out in the middle of summer so we were trying to find someone who could come out as soon as possible. They responded quickly and could've had someone out the same night, had it not started storming, but they were still able to get someone out the following morning. Ayman was great and solved the problem quickly. He let us know of things to look out for in the future with our 10yr old unit but didn't try to oversell us or pressure us into unnecessary work. We would definitely use them again!
★★★★★
SMART HEATING & COOLING is a top choice for your air conditioning needs. I contacted them on Tuesday about my unit not cooling. On Wednesday, Ayman, the service representative, arrived on time, diagnosed the issue in detail, and offered an option to repair or replace the unit. I decided to replace it. On Thursday, two technicians arrived promptly and installed the new unit in 5 1/2 hours, without taking a break. In my experience, no other company has performed as well as SMART HEATING & COOLING. I highly recommend them to anyone needing such services. THEY ARE 5 STARS ++++
★★★★★
Updated 8/2026: The first time they came out was for our upstairs a/c unit and this time we called them because our downstairs unit had stopped working. They answered on a Friday night and we were able to get something scheduled right away. Our tech this time was Spencer and he was also great and got us back up and running quickly. We've been very happy with the service both times and ended up signing up for the maintenance plan. Both times the techs have provided thorough explanations and taken pictures to show the work that needed to be done.
★★★★★
This is my second involvement with Smart Heating & Cooling, as prior, wonderfully smooth. The tech is really good, clean, neat and considerate. The gentleman sent was a Tech by the name Jared(please pardon if mispelled) was early which I love, very presentable and totally approachable and trustworthy. He identified the problem within minutes and was very professional in his delivery. One of the best customer experiences I have had with contractors, Smart Heating & Cooling, definately a SMART choice, HIGHLY RECOMMEND!

IF A LEAK STARTS
Put Safety Before the Cleanup
If your water heater is leaking, keep clear of water near electrical equipment. A licensed plumber can advise on the next safe step without asking you to take the heater apart.
Keep a Safe Distance
Do not enter standing water or approach wet electrical equipment to reach a valve or switch. Leave unsafe shutoffs to a qualified professional or the utility.
Leave Covers Closed
Do not open electrical panel covers or bypass the heater's safety controls. Leave work on power or gas connections to qualified professionals.
Protect Flooring Only if Safe
A pan may help catch water, but only if you can place it without approaching hot water or electrical hazards. Your safety comes before protecting the floor.
