"Great Job"

The crew showed up on time and worked thru the day to remove my older furnace and air conditioning system and installed the new units on the same day. Did a great job and cleaned up all debris before they left.

"Best Price... A Pleasure to Work With"

I have used Stafford Mechanical for service since 2013 for all my HVAC. The company is very professional and knowledgeable. I needed to replace my 18-year-old oil boiler, and they quoted me the best price compared to other companies in the area. I would highly recommend them for any of your HVAC service. Bob the owner and the service crew are a pleasure to work with.
