Been using Crystal since we moved to TDL in 2012. Every time they come out for the seasonal checks, the technician is always friendly, courteous, and does a thorough job. They also are quick to answer questions and also offer suggestions about heating and cooling. My wife and I love the fact that we signed up for seasonal inspections and the office always calls us to remind us to set up an appointment - it one less thing that wife and I have to concern ourselves about! We know that our heating and cooling systems are being carefully checked and monitored and it one less concern for house ownership.

We have been customers of Crystal Heating and Cooling for many years. We purchased a new HVAC system from them and they have been great about keeping it tuned up and inspected each season. The guys that come out have been great. I'm fairly certain we've met them all! We've had some hiccups in the system, but the guys are right on it when we call and always remain professional. We are extremely pleased with the guys who come out, the girls in the office and Mike, the patient man who has been so good to us. I highly recommend Crystal Heating and Cooling for their HVAC systems and most of all for the people who make such a difference. Thank you!

We have had Crystal do our spring and fall maintenance on our HVAC systems since 2011 when they added a system for our home expansion. I find the Office staff are very friendly and accommodating, plus we have had Gary do our maintenance for about 6 years and he too, is very customer oriented and very professional. His knowledge of HVAC provides longer life to our systems and helps us actually save money in the long run. I would recommend them to anyone!
