Reviews of local pros in Festus, Missouri

I was very impressed with the customer service A+. The project manager Josh was very professional and very knowledgeable about the product and how they would install. A+. The two gentlemen that installed our mini spits where tope notch. Sorry don’t remember their names but worked from the time they got there in the morning until finished. They made sure before leaving to go over everything with us about the product. A+. From the time we called to get an estimate and have installed was under a week. Great service. Will highly recommend.

Jack came in a cold, cold day to maintain our system and make sure that we will through the rest of winter. He arrived during the hours in which he was expected. He behaved very professionally, and gave us a summary of the work that was done.

Jack was a great technician. He was knowledgeable, personable and has good communication skills. I always recommend Crystal for HVAC service and replacement.

Ron worked efficiently and shared his findings with me. I was surprised when he told me the bill was $217. I was told the initial charge would be $97, that covered the first 30 minutes. Ron was here for about 45 minutes, so I figured around $150, but Ron said there was a $120 charge for "diagnostics". Isn't that part of troubleshooting the problem?
Just a little misleading, if you ask me.

The two guys showed up on time and was very friendly, professional and knowledgeable, they had concern about what was going on and it ended up being a tricky problem but they stayed until they figured it out which other companies could not do. They also told me if the problem starts again to call them and they'll come back for free. Awesome company and workers. I should have called Crystal first.

The guy came in and found the problem so easy. We were scheduled for an inspection which was going to be a lot more expensive but after he got here and realized it really should be a service call and got it changed to save us some money. He was very nice and personable and talked to me the entire time he was replacing our thermostat. We will be using anytime we need anything done to our HVAC! thank you!!

Appreciate the rapid response 2 days in a row. Both techs did a great job. Now just crossing fingers that the repair work for this upcoming cold weather will last the rest of the winter season. Thank you.

Had a different company show up the day before flipped my breaker on inside my furnace said oh let it run it'll get hot I asked him if the elements were good he says they're working I said that's not what I asked I said are the elements good he says yes come to find out with Crystal came crystal found two wires of the three elements were burnt, along with the connector . that's why I wasn't producing any heat but it kept blowing and .I tried to let the other company know this but I fell on deaf ears. thank you Crystal ,thank you Tyler* very much for your help. yu heated my ENTIRE house. thank you,many thanks. thank you too Jessica *

This company has prompt service, reliable assessments, and reasonable prices. They are very informative and thorough. Polite service from the technicians and office staff. Thank you Crystal Heating and Cooling, a future long-term customer here!

Our AC unit kept tripping the breaker, and Crystal was able to fit us in, in a timely manner, and send someone out to fix it. Andy was so professional, knowledgeable, and personable. He diagnosed the problem right away, repaired it, and checked the unit out completely. We purchased their service agreement, for them to come out 2 times a year, to check everything out; based on his abilities, the quick response time, and for the peace of mind, of having the AC & Furnace, inspected and checked out. Would highly recommend Crystal.

Very quick response to my problem. They even came out Saturday to give me options and worked thru financing with me and got me scheduled for the next Monday. The installation went great and they took away all the old stuff. Very happy with the service. Thank you!

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.
