Heating & Air Conditioning / HVAC near St. Ann

“After getting my information, a technician (Eric) called me back within 10 min. He asked me some questions. Let me know I would get a call in the morning for a time slot. He was even nice enough to contact me same day, evening saying it supposed to cool off, to open windows & turn fans on. It’s a great feeling to have someone go the extra step to advise you of ways to help, until they can get to you. He came out the next afternoon & I’m

“Ayden Schrader was very professional, on time, and VERY knowledgeable about central air units for being a young fella. Ayden did EVERYTHING possible to fix my unit but, unfortunately, my compressor was bad.
Assured heating and cooling are looking into a possible replacement compressor or, IF I buy a new unit, I WILL definitely have Assured heating and cooling do the job. Assured heating and cooling is a MUST if you need anything done.
VERY reasonable price and a VERY professional company. If you call anyone else, you will be making a big mistake. Thank you Adyen Schrader and everyone at Assured heating and cooling. You all rock...
UPDATE--Assured came back and got my heat working that was not working. Assured is the best of the best. ALL my heating and cooling work will be done by Assured heating and cooling.“

“My family, friends, and I have consistently been using St. Louis heating and AC recently on a few different installs now over the past year. All have been great experiences.

A couple weeks ago I also got a whole new HVAC unit. So far it has been great, and zero complaints. Overall the team that came out to do the install, did a fantastic job with their work and all were exceptionally professional. Couldn't be happier with the work done.

Lastly, The Wells Fargo financing options offered also significantly helped make this a pleasant experience.“

“Great company....friendly, professional and job well done. They were very good at cleaning up and disposing the hot water heater. I would HIGHLY recommend this buisness. My warranty covers the majority of cost..couldn't be happier. I had to get a up to code and out of pocket was reasonable.“

“Before I heard about Reliable heating and cooling, I called a different company to come out and do an air-conditioning maintenance and check up. Next thing I know, the company is trying to sell me a $23,000 system and downgrade me to an 80% efficiency system instead of the 90% that I already had installed. I called Reliable Heating And Cooling to get a second opinion. They told me that the system looked fine for its age and the only thing they recommended replacing was the contactor and capacitor. They said it would be under $300 for the repairs and the maintenance. I would highly recommend this company. They are trustworthy and reliable.“

“Extremely pleased with this company. Contracted them to install HVAC systems in our home. Very reasonable and competitive pricing; excellent customer support and the install crew was professional and a great group of guys. Aidan was our lead service specialist and he was fantastic to work with providing good advice, explanations and follow-up. Office staff was also responsive and helpful at every turn with Tracy providing timely and accurate information. Really could not have been more satisfied.“

“Al-Don has done a ton of work for us and Jeff and his team always deliver. Ed, Boyan, and the rest of the crew all work diligently and professionally to make sure the job gets done right. We’ve used them extensively for servicing our radiators, and are very happy with our new boiler and indirect water heater.“

“Isolated AC failure and quoted a new system. Install is scheduled scheduled for Wednesday.
Prompt and efficient.“
