Common questions
Do I need to replace my whole system, or can a contractor just repair it?
That depends on the age of your equipment, what's failing and how it was maintained. A contractor should be able to explain the tradeoffs for your specific system rather than defaulting to one answer. If you want a second opinion, ask another contractor to look at the same equipment before you decide.
What does “source verified” mean?
The listing's contact details and operating status matched an official public source when we last checked. It is not a quality rating or endorsement.
How quickly can someone come out for a no-heat or no-cooling call?
Response times vary by contractor and by season, especially during a cold snap or a heat wave when demand is high. Some contractors offer after-hours or emergency dispatch and others do not. Ask directly about current availability rather than assuming same-day service.
What should I ask before I let someone start work on my furnace or AC?
It's reasonable to ask for proof of insurance, a written estimate and an explanation of what the job includes before work starts. You can also ask whether a permit is required for the job and who is responsible for pulling it. A contractor should be willing to answer these questions without hesitation.
Does a lower quote mean a worse job?
Not necessarily. Price differences can come from the equipment brand, the scope of work or how a job is staffed. It's worth asking each contractor what's included in their quote so you're comparing the same scope of work, not just a number.
