A heat pump not cooling on hot days is most often due to poor airflow (clogged filter or blocked outdoor coil), low refrigerant, or a system that’s undersized for peak heat. The most common real‑world cause we see is a dirty filter or outdoor coil that chokes airflow and makes the system run but not drop the temperature.
We handle these issues routinely across the Cambridge area during summer heat waves.
- Replace or wash the air filter; confirm all supply and return vents are open.
- Gently rinse debris from the outdoor coil with power off; keep 2 feet of clearance.
- Verify thermostat is on Cool and set below room temp; check breakers aren’t tripped.
- If air is weak, lines are iced, or the outdoor fan/compressor won’t start, schedule service; systems near 15–20 years or with repairs approaching 50% of replacement often warrant planning a replacement.
Turn the system off if you see ice on the refrigerant lines to prevent compressor damage. <br/> Updated: 2026-04-01 <br/> Need help in Cambridge, MA? Call (508) 501-9990 or book online.

There isn’t one fixed annual price. The cost to service a heat pump depends on system type (ducted vs. ductless), the tune‑up scope, and whether you add a ductless head deep cleaning. Endless Energy offers annual tune‑ups and maintenance plans, and maintenance is required to keep some manufacturer warranties (up to 12 years) valid. A technician will confirm final pricing after an assessment.
Quick checks typically included:
- Annual tune‑up and thorough inspection.
- Filter and airflow review with maintenance recommendations.
- Optional deep cleaning for ductless indoor heads.

In Massachusetts, typical heat pump install costs range from about $6,000–$14,000 for a single‑zone ductless system. Whole‑home or multi‑zone/ducted projects often run $14,000–$24,000. Electrical panel upgrades can add $1,500–$4,000, and ductwork changes can add $2,000–$8,000. Mass Save rebates, instant rebates on select installs, 0% HEAT Loan financing, and the federal 25C tax credit (up to $2,000) can reduce net cost. A home assessment in your town confirms the final price.
