#2
Tobacco Road Heating & Air
“It is based in Hillsborough and offers residential heating repairs, with its owner reporting more than 15 years serving the area.”

Passed

Warren-Hay Mechanical
“Its local service history, NATE-certified technicians, emergency availability, and range of residential heating services make it the strongest documented all-around option.”

#3
Mechanical Comfort
“It is family- and locally owned and provides heating and cooling repairs, replacements, and maintenance in the Hillsborough area.”

Passed
Yellow Dot Heating & Air Conditioning
“It serves Hillsborough and offers broad home services, but the evidence I found identifies it as a company sold to a family office, so I favored locally rooted operators for this general recommendation.”

#2
Tobacco Road Heating & Air
“It is Hillsborough-based, offers residential air-conditioning repair, and customer testimonials describe responsive service.”

Passed
Yellow Dot Heating & Air Conditioning
“It advertises 24/7 call answering and rapid dispatch, but Warren-Hay's local page specifically qualifies its same-day appointment availability and describes 24-hour emergency repairs.”

Question 5 of 6

First

“It offers maintenance contracts but only provides a contact form and phone number, not a date-and-time booking form.”

Question 6 of 6
