Customer story in Schertz

New air conditioner and heating system—installed

AC & heating repair san marcos tx

Problem: Schertz resident, Ralph H., knew he needed to get a new heating and cooling system—sooner rather than later. In previous months, he noticed his 16-year-old AC unit was taking longer to cool his home, and felt a decrease in comfort. Ralph decided to call Reliable Air to get a quote for a new system.

Solution: We sent one of our comfort specialists, Mitchell, to Ralph's home to give a free quote on a new HVAC system. While he was there, Mitchell performed a load calculation to find the right size system for Ralph's home. After that, Michell gave Ralph recommendations on different systems that would work for his home, and upfront prices on the cost to install each one. Ralph chose a system and the next day, our installation crew installed a new AC and furnace in his home.

Ralph gave this 5-star review and had this to say about his experience working with Reliable Air:

“This team and company did a great job”

“I will say this company did a great job removing my old AC unit and adding a new unit. The salesman Mitchell was a very good salesman and answered my questions and concerns. I wanted a central AC and heating system installed quickly and this was done with no problem at all (next day after signing contract). They worked as a team in getting the job done. (They were people you feel you could trust.) I met the owner (Allen) who also made me feel that I had come to the RIGHT COMPANY for the job. I feel they will take care of my needs in the future.”
