HVAC reviews in Festus, Missouri

Outstanding job. Joe came over and cleaned the living daylights out of all our ducts, vents, and hvac system. Boy I’ll tell you what she’s running like a song now. Happier than a pig in poo with Joe and the work he done did.

They are very courteous on time, keep you updated on what they are doing. The price is very good. I loved that after they got done the temperature was perfect and the air was blowing so much better!! Would definitely use them again and recommend their services.

Both technicians who came out to install the new unit were great! Easy to talk to, explained what was going to take place that day and cleaned up everything afterwards. Before they left they explained my maintenance items and when to call them for assistance.

Sorry it has taken so long to give this recommendation to Joe and Crystal Heating for the outstanding job done cleaning ductwork in our home. There is a VERY noticeable difference in the dust in our home. I often told my husband that we lived in the dustiest house in our town. That is no longer true. We had our ductwork cleaned before with no visible difference in dusty floors. This time…it’s amazing. Thank you Crystal Heating!

Andy was great. Very upbeat and polite. He was prompt, and he finished the work very quickly, and now everything works just as it should! Thanks!

It was a pleasure Having Randy and Jason install our new heating and cooling. As soon as they got to our house, they got busy. Did the job cleaned up and explained everything to my husband showing him how everything works. Hard workers!
They did an fantastic job:) Thank you

I would also like to give a fantastic job that Joe did on cleaning the air duct and vent cleaning. Joe is a very hard working man. He did not stop until it was done and he’s so detailed. Thanks so much For an awesome job that you’ve done and take care of yourself.

Jason and Michael were awesome! They did a great job of installing our furnace, explaining things and cleaning up after they were done! We’ve always had a great experience with Crystal Heating and Cooling!

Very thorough. And did an excellent job cleaning out the vents. Already a huge difference in dust not settling the very next day. Trustworthy company, and excellent service.

Our AC went out, after calling around and getting several different quotes we went with Crystal Heating and Cooling. Mike and Mason did the install and they were great, polite, professional, and answered all my annoying questions as if they were important to them. They were very diligent and completed the install in no time.

The guys were nice. Efficient, respectful answered all my questions. Did a great job. Cleaned up there mess. They set my phone up to control the thermostat. Thank you so much.

H. Thompson was great. Called to let me know he was on his way. Reviewed the service he was there to do. Then after he let a know he was complete and informed me that my heater had an issue that needed to be repaired but was under my warranty.
(Waiting to hear from Crystal to schedule the repair).

I had a rep come out on a Monday to discuss our options as to what would be the best for our situation. We already have a working furnace but no a/c. We’ve been using window units for 3 years and worked fine but kind of a pain to deal with when it’s time to install and remove every year, and storing them. Anyway, we received a quote on Tuesday which was on par with other quotes. What sold me was the brand of equipment they install. I felt it was a reputable brand name product. Install was completed the following Monday. New furnace, new ac unit, condensation pump(no floor drain) new WiFi thermostat. Up and running by the time i got home from work. Very satisfied.

Kyle was great! He was very professional, thorough and explained everything very well. I appreciate how quickly they were able to come out and check the system.

Spring maintenance on A/C. The technician was friendly, courteous, and professional. always have great service with Crystal! and they have fair prices.

Our system wasn’t cooling all last year and the power bill was insane. I had a tech come out and we determined I needed new parts. They didn’t sell me a system but instead explained what I needed and why. They put me first in an industry that all too often favors a big ticket sale.

These guys are seriously trustworthy

I have purchased two air conditioning and heating systems from this company. I trusted them which was my mistake. I purchased a unit in August of 2024. I had a friend come over for a visit and he said your heat pump shouldn't be making that noise when it turns off and on. I called the company to get their input because it has been doing that since it was brand new. They sent someone out and told me there was nothing wrong with the unit and charged me $97. I was told the labor warranty was only good for one year. I said the unit had been making that noise since it was new and I didn't realize it was not supposed to make that noise because I trusted the installer. The manager told me there was no way that they could refund my $97 because it was 2 months past the labor warranty. She said it takes that much money to get us Tech out here. The unit cost me over $15,000. Do not, if you use this company, trust them to make sure it's right. Call them out at any little noise you hear as many times as you need to in the first year or else you'll be paying also.

Mr. Rickmar was great, he explained my system to me and why it was doing what it was doing, things i should be concerned with and normal operations since we had never had a heat pump before and didn’t know anything about it and he explained in terms that I could understand which I greatly appreciated. He promptly fixed our system and got it running smoothly again! I can not thank him enough and we will be using Crystal heating and cooling for our routine maintenance and any other issues we may have arise.

We were having trouble with our 20-year-old system and contacted these guys. Fortunately, they were able to come out within a few hours and explain what the problem was with my system. We got a replacement one figured out quickly and we also shopped around on price and these guys were priced very well. The installation was just finished yesterday and everything went very smooth. Their customer service is great and also the employees are very professional. I would hire these guys again for sure!

We’ve had service from Crystal Heating and Cooling for many years. They are great at regular maintenance, and in emergencies they respond quickly and get up and back running ASAP. I especially like that I can request a particular technician….he knows our home and our units….it’s a friendship and support system I greatly appreciate! This is a top-notch company with great employees!

Our inducer motor was loud. We scheduled a visit and the tech was courteous, timely, and called ahead as promised. The part had to be ordered, but arrived and was installed the same week. My concern: why did the inducer motor on our furnace that was installed in May have issues just 7 months later? Fortunately it is covered under warranty.

What a wonderful company! From the moment they came to install a new more efficient unit they were friendly and very professional all at the same time. Beautiful job!! We look forward to getting our furnace from Crystal Heating and Cooling in the up coming year .. again-great job guys...A+
