"AC went out on a Saturday afternoon in July. John Q picked up immediately, was at my house within two hours. Fixed it the same visit. Didn't try to upsell me anything I didn't need."
"Replaced our entire HVAC system last fall. Got three quotes — John Q wasn't the cheapest but he was the most thorough. System runs better than anything we've had in 20 years."
"Called at 11pm when our heat stopped working. He answered, talked me through a quick check, and had someone out first thing in the morning. Exactly what you want from a local company."
