Joevani arrived within an hour of our call to diagnose the problem with our furnace. The heat exchanger was cracked. Since the furnace was 25 yrs old, we opted to replace it with a Bryant Preferred 96% efficient furnace. Chris and Brandon installed the new furnace. All 3 of the guys were knowledgeable, friendly, and did a great job! We highly recommend Square One Heating & Cooling!

We had a problem with our furnace. I requested an appointment on line and they called back very quickly. Nick arrived and was very knowledgeable and professional. He assessed the problem and was able to help us with getting the service covered by warranty. Thanks for awesome service!

"Buyer Beware" My Honeywell whole house humidifier was constantly dripping water, in spite of the act that the humidistat was turned "Off"! There is only one active part in the humidifier and that is the solenoid, which controls water flow, either on or off. Since the solenoid hadn't stopped the flow, it needed to be replaced. There was a "Square One" sticker on the furnace so I assumed they were the vendor of choice and called for service. Upon completion of the replacement, I was given an invoice that listed "Service Call Diagnosis" - $75.00. (Somewhat

Great service they replace both our ac and furnace. I had a cold room in the winter that never heated - Square one guys figure out bad installation they corrected and I have better heat for the 1st in my family room. Then this year, 2 years from installation I call them with no ac, they came out and found problem that was not their installation and took care of it for us under our warranty. Can't say enough about their great service and friendly professional staff.

Today was the second time we have called Square One with an emergency - I spoke initially with Erika at the office and she promised to call me right back. Not only did she call right back - she managed to squeeze us onto the schedule! Our first experience was with Jeremy who replaced our entire furnace and today we had the pleasure of meeting Chris! I run a wildlife rehabilitation center here and I need to be able to maintain the temperatures for the patients. Chris, came out, fixed our furnace, checked to make sure all of our systems were up to par and gave maintenance tips. It is hard to find

After our basement flooded, we lost our water heater. With everything that's been going on in the community I was pleasantly surprised that Shawn and Jeremy could come out the next day and install a new one. They were very knowledgeable and did a fantastic job. Thank you so much for all the hard work!

Our heat went out on a freezing cold day. I belong to a community page on Facebook and asked for recommendations and several people recommended Square. We called and they came out later in the day. Chris was our technician and was very fast, efficient, and friendly. He educated my husband on the problem and answered several questions that we had. The price was very fair (far less than I expected and was quite frankly terrified of). And to take the honesty and trustworthiness to another level....he told us of another part that was on it's way out....but told us that we still had time

This place is great. I had my furnace go out at the beginning of winter and I was new to the area so I didn't know who to call. I got a recommendation for these guys after a couple really expensive alternatives and they really were great. I ended up getting a better unit then any other business quoted me for the same price as a cheaper one. They also filed my rebates for me which is one less thing that I had to do.

When they came and installed the unit the guys were great. Really polite and quick. I am an engineer so of course I had to ask questions and watch the entire time just

Square One Heating and Cooling has been so great to work with. We have an older home and have had multiple issues with our furnace. Chris from Square One has come out a few times over the past couple months to preform the different services. He is always friendly, considerate and very patient to work with. He has a strong knowledge of the problems and has fixed them on the spot.

We have been happy with Square One because they are polite and friendly on the phone and in person, which is refreshing. Thanks so much Square One for saving the day...again and again!
