Overview

What to know before you book.

Specialty services are the precision jobs that take trained diagnostics and certified handling rather than a quick swap. Boston Comfort Systems covers advanced HVAC troubleshooting, refrigerant leak detection, EPA-certified refrigerant recharge and recovery, smart thermostat installation, and hands-on help claiming Mass Save heat pump rebates. When a system is short-cycling, low on charge, or throwing errors nobody else could pin down, this is the work that finds the real cause.

Our $99 diagnostic gets you a methodical root-cause inspection, not a guess, and it's waived when you approve the repair. As a Mass Save participating installer, we can help you access rebates up to $8,500 plus a 0 percent HEAT Loan up to $25,000 on qualifying heat pump projects. Every fix comes with flat-rate upfront pricing and EPA-certified refrigerant work handled to code.

FAQ

Diagnostics & Specialty questions, answered

You pay $99 for a thorough root-cause inspection of the problem, and that fee is waived when you approve the repair. Any recommended work is quoted with flat-rate upfront pricing first.

Yes. We use leak detection to locate the source, then recover and recharge refrigerant using EPA-certified handling. Chasing the leak first matters, because simply topping off charge only delays the next failure.

A smart thermostat gives you better scheduling and remote control, and many pair well with heat pump systems. We match the thermostat to your equipment and wiring so it actually works with what you own.
