Will Lewis came out to service our twice yearly check up and absolutely loved him. He was thorough, professional, really sweet, knowledgeable, informative and a pleasure to see he represents a really good reliable company. He came the same morning I called so on their trucks it says rapid response and they arent kidding. Thank you and thank you for hiring people like Will.Kathy Owens

On the first extremely hot day of 2021, our AC stopped working. Crystal Heating and Cooling was incredibly responsive. The service technician, Trent, could not have been more experienced, professional, efficient and friendly. The AC is now up and running COLD air. We will be returning customers for all of our HVAC needs, including their maintenance services. My husband and I definitely recommend this company.

I work in insurance and often need documentation of updated HVAC for mutual customers. They are great about getting me the information I need. They take great care of their customers even after the work is done. That is the kind of service you want!

Fixed income pay major or nothing $500+$140 for nothing worse service ever he even told me i could have gotten the parts for $20 and still charged me $140 for telling me yes it is broken.........well duh i called you to fix it not charge me $140 to tell me something i alreay knew i am like wow some of these people are all about money and not human lives or having a warm home for the winter

He done a great job and very professional at his work.

Outstanding service, amazing response time, excellent value for money. We sold our house and the furnace went down before closing. Crystal found the life time warranty on the part (no other company offered that) and tried repeatedly to resolve the issue despite Carrier sending the wrong parts etc. Crystal staff were amazing, offered options and ultimately installed a new furnace (I insisted - they had other options to save me money but I just wanted the situation resolved asap). They really worked collaboratively with me to make sure I got accurate information and overall I would highly recommend them. If I hadnt moved out of region I would use them always moving forward. Really amazing team!!

We had a complete HVAC replacement. They literally replaced everything: furnace, ac, ducts, vent covers, and thermostat. (even the wires for the thermostat) they moved our return air grill to a central location and added 2 new runs for rooms that didn’t have vents and ran all new electrical wiring for the new system. Martin and Chris were very polite, hard working, and professional. They made sure they took care of our home as if it was theirs.

Best HVAC company west of the Mississippi. Friendly service people. We were so impressed we have then doing our maintenance twice a year. Worth every penny and we save money too. Well done Crystal.

The crew was super friendly and very professional. Cory made sure to explain everything in detail and all my questions were answered. I was guided through the process and it was relatively painless considering it was the replacement of an AC unit. Even from the sales perspective I felt like they were making sure I had the right unit for my needs and at a competitive price. I highly recommend the team at Crystal Heating & Cooling.

I have been using Crystal Heating and Cooling for around 7 years. They are always friendly and knowledgeable. They call ahead to tell you that they are on their way, this is important because a lot of the time I am at home alone with my son. Carl was great with my son and dog on his last visit. I high recommend them. Also the service contract is worth it!!!

I had called earlier this morning because our heat had gone out. They were easy to work with and Duane G. was understanding ad helpful to work with our busy schedule. My husband was home when the technician came and got us back on track quickly! Pro military as well and we are extremely grateful!

Crystal Heating and Cooling always does a great job. Darren H is friendly and knowledgeable and does a great job of explaining the problem and presenting options.Cory W and another service person installed a new furnace and heat pump. Both did a great! job. Very polite and went over everything thoroughly before they left.

Very good service. Darren explained why a new capacitor was needed and also informed me overall about the condition of the unit. As this is a new house, I very much appreciated the time he took to update me and give me a preview of possible future needs. I had several phone calls also with other staff, and was very pleased at their immediate response and courteousness.

I only called Crystal because that’s who my home warranty company suggested, first of all. My unit needed Freon and they stated I had a leak. My technician refused to go in the attic (where my unit is) because it was hot and he didn’t have to, so I had no idea where the leak was. They went ahead and put Freon in my unit though. I called and spoke with Duane and he said since his workers are Union they don’t have to go in the attic if they don’t want to. Duane then said that he could send someone out that next week to look for a leak but I would have to pay another service fee for them coming back out. I’ve already paid once for the service that I didn’t get..why would I pay again??

Quick and quality service, was very pleased! Also knowledgeable and fairly described the problem straight to the point. Will definitely use for future issues with any of my homes heating and cooling.

Chris S. and Kyle were a great team. They were very courteous and informative. The ongoing banter between them while they worked was very entertaining. Although they had fun while they worked, their knowledge of their duties and work ethic could not be questioned.

Field Service Representative, Darren H., did a fantastic job of diagnosing and correcting the problem with my furnace. He explained everything and worked very efficiently, then tidied up afterward. My past experience with Crystal Heating and Cooling was also very good. I highly recommend this contractor!

Crystal Heating & Cooling Inspection program keeps your heating and air conditioning running at top notch. I dont ever worry that my unit wont make it through the cold days or hot nights. They clean it and catch problems before they start with good old maintenance. Every employee is a pleasure to work with. Mark E even let my dog watch. Charlie, the dog, has a new friend! Use Crystal with confidence.

Cary was very friendly, professional and did an excellent job. He even explained that he turned out the lights in the attic and basement when he was done. He made sure that I was satisfied and asked if I had any questions before he left.

Darren H was our service technician today and was extremely knowledgeable and helpful. This is our 2nd time using Crystal and they are great to work with.This service call would not have been had they not called to remind me of already paid for the service last Spring but I forgot! Thanks for your honesty - hard to come by these days.

Darren was great and very nice He explained what he was doing and made the experience a good one. Thanks to this man my house is cool and things are working well. I will defiantly use Crystal Heating and cooling for all my repair needs.

Darren H is always very helpful and courteous! Hes been servicing my and my moms heating and cooling units for years, maybe even more than a decade :-) Always give the best advice, answers all my questions, make great recommendations and not to mention leaving our property cleaner than when he started. Crystal H&C is a great company! I always recommend them to friends and neighbors!

Everyone was very helpful. I was kept informed of when the tech would arrive... right on time. Andy was very helpful. He found and corrected the problem with my outside unit quickly. Everythi g is working great, thanks!

Andy was very professional and courteous, very knowledgeable and got my A/C back up and operating in no time. A shout out to Duane Guenther and the whole staff at Crystal Heating and Cooling for their quick and timely service...... I have been dealing with this company for more than 15 years and have not been let down yet..

Joe did awesome work cleaning my ducts. He found a problem with my dryer vent and fixed it. Super nice and trustworthy guy would highly recommend him to anyone whos needs their ducts cleaned.

My wife tells me the tech was professional however my review of the invoice versus what was done did not add up . $213 and never put a part on the furnace . Nothing was done that I could see other than claim it needed replaced . I think this company is one of those sell new units in volume and cant service anything. The claim was I had a crack in the heat exchanger . When Donny the salesman called me I said I have concerns about buying another Carrier unit if this 16 year young furnace has a cracked heat exchanger . He then said oh no worries Carrier has a lifetime warranty on these heat exchangers . I said thats great then your the Carrier dealer take care of this one on that lifetime warranty. He said oh thats up to you to call Carrier & ask for that, in other words I just want to sell you a new furnace not stand behind my brand that I am claiming has failed. I would not use this company again . Rich Kennedy

Tech was very pleasant and clean. Explained everything in detail and was sure I was satisfied before he left. Turned out to be a minor repair and was quickly fixed. I would request him again.

Cary J. is always a welcome sight for our bi-annual heating and cooling system maintenance. He is efficient, considerate, reliable, and hilarious!We have been using Crystal Heating and Cooling for almost a decade. They are fabulous and we appreciate having such a consistently great experience with them.

Theyve been to our house numerous times to resolve the same issue with our central air. Each time they were there, they informed us that it was repaired. Things were replaced on the unit. However, the issue was still unresolved. It took the very last gentleman to actually diagnose the problem. It was something so simple that the other guys SHOULD have noticed the 1st visit!

Darren H was very professional and right on time. He found my problem and fixed it very quickly. He was very careful not to make a mess and cleaned up everything as if it was in his own home. He was very friendly and explained very well the problem.Darren is an excellent technician and definitely professional. I would give him a 12 rating out of 10!!

Crystals service has been excellent. Darren, our serviceman, explains everything he is doing and checks out everything for a problam free season.Its good to have a company you can trust to take care of your heating and cooling system.

Jason and his team at Crystal H&C went above and beyond to provide my family with stellar service. I had my HVAC system replaced by them. Not only did they correct the mistakes from the prior owner(s), he educated me along the way. No short cuts taken here- he was prepared and very thorough. Based on my experience, I highly recommend Jason and his team.

This is the second time we’ve had Darren out to the house and he’s the best! Always nice and takes care of what’s going on! We appreciate it!

Chris W. Installed A-coil and checked cooling system. Chris knew his job and performed in a professional manner. Recommended service tech for this company. Kudos.

The staff was very professional and personable. They performed their jobs very well and effectively. The maintenance was done very quickly and without much interruption to my personal life.

Mike H. fixed our AC unit quickly and did a great job of explaining what was wrong in terms I could understand. He was courteous and professional and I would highly recommend him!

Mike has serviced our equipment for some time now. He is always courteous, friendly, willing to answer questions, and helpful in showing me how things work. We have enjoyable conversations off-topic, and I appreciate his interest in keeping my HVAC system running properly.

Cary J. came to my house to fix a screwed up service call from a different tech. Cary was excellent, thorough, professional, and very affable. If you need repair, ask for Cary. He redeemed his company quite nicely.

I have been doing business with Crystal Heating and Cooling since we built our house in 1999, they have replaced both furnace and air conditioner in one of our rental properties and our home. Recentlyanother our the rental houses had a problem with the air conditioner andnaturally I called Crystal Heating and Cooling for service on that unit. They showed up and called me to tell me that they had located the problem and the unit need 3lbs of refergirant at $86.00 a pound to correct the problem, I approved he repair and that was that. $375.00 later I wasassured the problem was corrected. 4 days later my renters, who are intheir 80s called to tell me the air conditioner was not working, it was on Saturday so I called the emergency number for Crystal and relayed the information to them that I was concerned for the well being of my of renters. As of Monday no one from the company had contacted me so I called again, they told me they would try to get someone out that day or the next. when the tech showed up they called to inform me that the unit had a leak, when asked why that had not been discovered originally i was told that now the air conditioner needed to be replaced. The whole episode has left a very impression with me after having had purchased3 complete heating and air conditioning units from this company. NEVER AGAIN !!!!Mike Bowzer
