Derrick came out to inspect my furnace and I had a great experience. He was friendly and knowledgeable and helped educate me on items that can help prolong the life of my furnace. I will continue using this company for my service.
I received a call from Liana asking when I would be available for a gas line install for the generator. She gave me a few options and clearly explained what would be done. The arrival window was small which isn't typical and I really liked that On the morning of the install it started with a quiet knock on the door. Brad arrived in the time window given and that knock alerted me but didn't wake anyone sleeping up. He introduced himself and gave an overview of what he was going to be doing. Very professional and personable. The work looks very good.Thank you
I have been a customer of Reliable Heating and Cooling for 20+ years. This installation HAVC is my second one. Reliable Heating and Cooling served me at my former home and now my villa. The installers were great! I was concerned about my carpet getting soil due to the traffic. They put covering though out where they were working. I thank you Reliable Heating and Cooling for another job well done. Give my thanks to the three young men who were wonderful and you to Marty for the pre-planning we experienced prior to installation. May God continue to bless you and your business. Again, thank you for a job well done...
