I've used Complete Comfort Heating and Cooling for almost twenty years. I have a yearly maintenance contract with the company. I have a geothermal heating system, which is unusual, and they are qualified to do the special servicing my system needs. I have never had a bad experience with a technician. All of them are wonderful! I would like to particularly praise Jalin--he deserves a tip! Complete Comfort Heating and Cooling technicians are always polite and they always arrive on time.
