What Our Customers Have Said About Us

I have been a customer of this company since 1999 when they installed my furnace and air conditioning in my new home. Since that time I have had Furnaces and air conditioners replaced in two houses.This past weekone of my renters notified me that the air conditioner was not working properly so naturally I called Crystal to make the repairs. I was told that the unit needed 2 pounds of refrigerant and I authorized the repairs. $375.00 I was assured that everything was fine. On Saturday my renters called to inform me that the a/c was not working. I called the emergency number for Crystal and informed them of the problem mentioning that the renters were in their 80s and i was concerned for their well being, by Monday i still had hear nothing from Crystal Heating so I called again on Monday morning and was told that they would try to get someone out that day or the next. My next contact from Crystal w as that the unit had a leak and when asked why that was not noted on the first visit the only answer I got was that a new unit was needed. I am extremely unhappy with that service after having been a long time customer. NEVER AGAIN will Crystal get any business or referrals from me.Mike Bowzer

The staff were wonderful. They worked quickly and were in and out of here in no time. The young man that worked inside the house was very friendly. All in all, this was a great experience and I would highly recommend this company.

I have had them service my equipment for over thirty years. I had always been pleased with the work they do. Today's technicians were courteous, prompt, and did the work without wasting any time. I would be happy to have them back next time.

I have always had a good experience with CH&C from the initial installation of my new Carrier unit and throughout the annual preventive maintenance and checks. My recent inspection performed by Darren H. was very thorough, professional, and personable. Thanks Darren for explaining each step of your process and recommendations for improved performance of our heating/cooling unit. I have committed to use CH&C for future maintenance and welcome Darren to provide our service.

Cary J. was on time. He was thorough, friendly, and explained many functions to me. He cleaned the system and assured all was running well. I would welcome him back anytime. Heather set up my appointment easily. I'm glad this team is working for me!

I had a great experience with air duct cleaning services from Crystal Heating & Cooling. The front office staff were very accommodating and answered all of my questions. They also were very upfront about the entire process and everything that was included, unlike other companies I spoke to where everything was an add-on. On the day of the service Joe arrived on time and explained the process to me again, and checked in throughout the day to update me on his progress and share photos of how things were going so far. I would definitely recommend this service to anyone considering getting their air ducts cleaned!
