What to Look for in a Furnace Repair Service

As they say, experience is the best teacher. And when dealing with such a complicated piece of equipment, you’ll want only the best and most experienced people on the job!

While a more experienced repair service may be on the pricier end, it’s absolutely worth it for your family’s safety and comfort.

2. Referrals

You can get referrals from trusted family, friends, or us! Even when you’re on the phone with a company, you can ask them for referrals as well (at least 5 is a good number)

Asking the company about their license can be a bit awkward, but it’s worth it. An official license indicates the company name, address, and contact info. It also includes a license number you can have checked by the right authorities.

4. Insurance

Any repair company worth its salt will have an insurance policy. If it doesn’t, you might want to keep looking.
