Tips For Choosing The Right HVAC Contractor

Research & Referrals

Before checking with commercial duct cleaning service companies, properly research your local HVAC companies on Yelp, Facebook, and Google. From there, ask your friends or your social media contacts for advice and referrals. Work with a contractor that has a good reputation for quality workmanship and customer service.

Safe & Certified

Hire an HVAC company with licensed, bonded, insured, background checked and drug tested technicians. Do not hesitate to ask the company for their license numbers, criminal background checks, and other drug testing measures to help protect your family and properties.

Get Estimates & Compare

Reputable HVAC companies will provide their customers with written estimates before the project begins. To promote trust, these estimates should be honest and fair. With upfront pricing you won’t be surprised by any unexpected costs. Your contractor should walk you through all the costs and fees prior to the start of any repair or replacement service.

Immediately you get the estimates, get quotes from highly rated contractors to compare costs and quality. However, avoid hiring the services of the company with the lowest estimate if the company is not properly rated online. Spending more money upfront for quality workmanship saves you a lot of frustration and costs down the road.
