HVAC repair
When the heat quits in January or the air conditioning gives out in July, you want a technician who shows up when promised and tells you the price before the work starts. That is how we work.

If you smell gas or a carbon monoxide alarm goes off
Leave the house first. Then call your gas company or 911 from outside. Do not switch lights or appliances on or off on the way out.
Signs it is time to call
Some problems have a simple cause you can check yourself. If these sound familiar, it is worth a visit.
- No heat, or rooms that never warm up
- The air conditioning runs but the air is not cool
- Banging, grinding, squealing or rattling from the system
- The system turns on and off every few minutes
- Water pooling around the furnace, air handler, boiler or water heater
- Ice on an air conditioner's lines or outdoor unit in summer
- A burning or electrical smell when the system runs
- Energy bills climbing without a reason you can find
No heat right now? Try the quick checks before you call.

Repair questions
Will I know the price before you start?
Yes. We find the problem first and tell you what the repair costs before any work starts. Nothing is done until you agree.
Which systems do you repair?
Furnaces, boilers, heat pumps, mini splits, air conditioners, water heaters and thermostats, in homes and businesses.
Is it better to repair or replace an old system?
It depends on the system's age, how often it breaks and what the repair costs. Our repair or replace guide walks through it, and we will tell you what we find when we see it.
Do you work in my town?
We work in towns west and north of Boston. See the full list of towns, or call and ask.
