Do you offer free estimates in Boston?

Are you available for 24/7 emergency HVAC?

Yes. We answer no-heat and no-cooling emergencies around the clock and prioritize same-day response across Greater Boston. See 24/7 emergency HVAC.

Why is my AC running but not cooling?

Usually low refrigerant from a leak, a failed capacitor or compressor, a frozen coil from restricted airflow, or a thermostat fault. We diagnose the actual cause first — see AC repair.

Why does my furnace keep shutting off?

Short-cycling is often a dirty flame sensor, a failing ignitor, a clogged filter, or a tripped limit switch. We find the root cause rather than just resetting it — more on furnace repair.

Do you service steam and hot-water boilers?

Yes, including radiator systems and oil-to-gas conversions that are common in older Boston homes, which many forced-air HVAC companies won't take on. See boiler repair.

Should I switch from oil to gas heat?

It is often worth it. The U.S. Department of Energy estimates an oil-to-gas switch can cut heating costs by up to about 30%, and modern condensing boilers reach roughly 90 to 95% efficiency. We compare your options on the boiler page.

Do heat pumps work in Boston winters?

Yes. Cold-climate heat pumps hold their rated heat output down to around 5°F and keep heating below 0°F, so a properly sized system can be the primary heat source through a typical New England winter. More in do heat pumps work in cold weather.

How much can MassSave save me on a heat pump?

In 2026, MassSave rebates reach about $8,500 on qualifying cold-climate heat pumps, with more for income-qualified households and a 0% HEAT Loan. Confirm current amounts with MassSave — see heat pump installation.

How often should I service my HVAC system?

Once a year per system — cooling in spring, heating in fall. Homes with both a furnace and AC, or a heat pump that runs year-round, benefit from two visits a year. More on how often to service HVAC.

How much does HVAC installation cost in Boston?

Central systems generally run about $6,000 to $13,000 and ductless heat pumps about $4,000 to $8,000 per zone, before MassSave rebates on qualifying equipment. See the HVAC installation cost guide.

What areas around Boston do you serve?

Boston and the Greater Boston area, including Cambridge, Brookline, Newton, Somerville, and Quincy.
