Cooling calls in Boston
The cooling season in Massachusetts does most of the damage to equipment in Boston. Humid summers load a housing stock largely built before central cooling, so retrofits dominate. Annual runtime hours, more than age in years, decide when a condenser starts failing.
We publish 36 ZIP codes for Boston. Travel time inside a market of this size varies enough to matter during peak demand, which is why the operator takes the ZIP code before anything else.
Local considerations
Duct condition in older Boston homes accounts for more lost cooling than equipment faults do. A system running correctly can still struggle to hold setpoint if the ductwork is leaking into unconditioned space.
A thermostat that loses calibration in Boston produces a complaint that looks like an equipment fault. A system that runs to setpoint but reads two degrees high at the stat is performing correctly, and the fix costs less than a refrigerant charge.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.

- Call today
- Read next
- AC not cooling
What to do while you wait
- Turn the thermostat to off. A system left running against a fault can make the repair larger.
- Look at the outdoor unit and confirm whether the fan is turning at all. Note what you see.
- Clear at least two feet of space around the condenser so it can draw air freely.
- Keep anyone heat-sensitive in the coolest part of the house with water within reach.

Boston HVAC questions
What happens if the breaker keeps tripping?
Leave it off. A breaker tripping on every cycle indicates a genuine electrical fault, commonly a failing compressor drawing locked-rotor current or a shorted fan motor. Resetting it repeatedly risks damage beyond the original fault.
Can someone come out today?
Sometimes. The line is answered 24/7 in ET, but same-day arrival depends on provider participation, your location inside Boston, technician availability and how heavy demand is that day. The operator tells you the window offered before you commit.
Why is my AC running but not cooling?
The three usual answers are restricted airflow, low refrigerant charge from a leak, or a failed capacitor stopping the compressor from starting. A technician separates them with a static pressure reading and a superheat measurement.
Can I get maintenance rather than a repair?
Yes. Maintenance visits cover coil cleaning, condensate drain clearing, filter replacement and a capacitor check. These are booked rather than dispatched as emergencies, and they typically cost less than a repair call.
What does AC repair cost in Boston?
We do not quote prices. The provider who attends inspects the system, tells you what the work costs, and confirms that figure on site before starting. Refrigerant leak work generally takes longer than a straight part swap.
