"Horrible company, horrible service, still waiting after 14 days for an update. Claimed they ordered part, then found out they didn’t order the part, then they schedule an appointment and didn’t show up. Dispatch was rude and they didn’t return calls and messages. Same company misdiagnosed my mom’s HVAC system and she ended up getting it replaced only to find it still kept shutting off because it was a gas regulator that was the problem all along."
