The CLOWNS are ABOUND in the HVAC arena! Having been through the J O K E that is True Comfort Mechanical. The one man show who shows up in an unmarked van, and no uniform but CHARGES you like he is. Amazing what passes for "professionalism" who is adamant your new systems out of warranty and charges you outrageously! THAT is True comfort, who by the way ruined my system that COLDMASTER replace UNDER WARRANTY, and with marked fleet of vehicles, professionals in uniforms. PAUL is the MAN!

These gentlemen are a pleasure to work with. All the techs are knowledgeable, polite, and very professional. The office staff is also polite and responsive. True "customer service", a rarity today. I stumbled upon this company, after dealing with others, and I'm so glad i did.

He was the third tech I called and he was the only one who knew what was wrong with my AC. He was able to come out the same day, explain to me what was wrong and while the part was being shipped he kept me updated. AC works great now.
