About Assured Heating and Cooling

With over 20 years of experience in residential heating and cooling system repair and replacement, we are committed to putting our customers’ needs first. We treat every home with the same care and respect as we would our own. Our transparent, flat-rate pricing ensures fairness—everyone pays the same rate for the same service, regardless of location or situation. For example, if your air conditioning system requires a simple part, you’ll pay the same as your neighbor for that repair. We proudly offer discounts to military personnel, first responders, and senior citizens as a token of our appreciation for their service. Please note that we do not work with home warranty companies. All services must be paid in full upon completion, directly on-site.

Tanya k.Oct 2026

I highly recommend this company. I almost never rate companies 5 stars but with Assured, I had no choice. They were prompt with scheduling, Jason (who knows about cars) and his partner ( I forgot his name) we’re extremely polite, professional, and engaging while still staying focused on replacing the furnace. Bruce also has a glowing personality. We will call on them them for alllllll of our heating and cooling needs. Oh, although we didn’t use it, they have financing available.

If I could choose all 5 options of what we loved about them, we would! So helpful and attentive! If we ever needed to, we would use them again.

Bruce is extremely professional. Was out at the location for a quote in less than 24 hours. Super responsive and great communication. I’ll be using them for my future homes in Saint Louis. A++

I got an appointment right away. Then they offer to come out even sooner. They were friendly and knowledgeable. The repair was very quick and for a good price.

They responded to me super fast and I was able to have my issue fixed by next morning. He made sure to check for any issues to ensure that the problem wouldn't happen again, and that tells me they truly care about their customers. I'd hire them again

ROBERT S.Apr 2024

They do work you Company and didn't show up. I talked to someone and are trying..find another company.

Mike H.Jan 2024

I called during the recent subzero temps this past weekend for some routine maintenance. They had someone at my house to look at the furnace within 48 hours. Very professional and nice. Didn’t take all day and cleaned it up.

very respectable

GELEE S.Nov 2023

Took time and explain the trouble with the furnace. A very nice dad and son.he was not pushy at all. Would definitely call on the company again.

Tracey B.Jul 2023

Bruce was outstanding and knowledgeable. The response was amazing. I will definitely use Assured Heating and Cooling again.

Anthony p.Jul 2023

Get the permit they stated they would take care so I dont have to pay for it. Also it's been months since they were going to handle it!

Jim B.Apr 2023

These guys were great. They came out the next day and looked over my system. Did a service and checked it for any maintenance issues. I would definitely hire them again each year for annual service and most likely when I have to replace the unit.

Tonya W.Feb 2023

Showed up when it was so short of notice in fridged cold weather. My Furnace is running and they went the extra distance to submit a part for a warranty replacement. Would recommend to other customers!

Scott A.May 2022

Bruce was extremely helpful in repairing my AC that went out. He was prompt, trustworthy, and very affordable. He explained the problem with the until thoroughly and understood I was on a budget throughout. He got the older unit I have up and running quick order. Other (bigger, highly marketed) companies I’ve used before tried to oversell me and gauge me. Bruce and his company were the opposite. They do right by the customer. I highly recommend using them for anything HVAC related!

Wonner B.May 2022

They was very quick and knowledgeable. They fixed the problem in no time.

Sara E.Feb 2022

Assured responded immediately and came out the same day. As expected, I needed a new furnace (it was ancient). They walked me through what had to be done and what didn’t which I appreciated. I got multiple bids and Assured’s had the clearest scope of work and was the least expensive! I did some research and across hundreds of reviews, I could not find a dissatisfied customer. We scheduled the replacement for the same week and their team arrived on time, masked, and ready to work. They finished within a few hours and my house is comfortable again. I will recommend them to everyone I know!

Yvette C.Dec 2021

This company responds as soon as you call them. They booked the appointment and came out the next day as promised. My son in law had the problem diagnosed. It took them no time to fix it.

Sriman K.Dec 2021

Bruce was great, prompt, communicated well. diagnosed the issue quickly and fixed it quickly. I am definitely satisfied
