About

"They installed a new furnace to replace my old one. I was very impressed by each individual who I met. Jason the salesman was professional and courteous. He was friendly, professional and had great follow-up. Originally I was not going to purchase a new system. But decided to go ahead.

Your own checks

What to check before you hire

Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Contractor licensing in the US is set by each state (and sometimes the city or county). For electrical, plumbing, HVAC or any major build, confirm the trade is licensed on your state's licensing board before hiring. Unlicensed work where a license is required can void permits and insurance and leave you no recourse.
Ask for a lien waiver as you pay each stage: in most US states an unpaid contractor or subcontractor can place a mechanic's lien on your home even if you already paid the main contractor, and a signed waiver is your protection.
Confirm they cover your area and can actually come out in your timeframe before anything else.
