Central air and ductless mini-splits diagnosed and fixed — often same-day — with the price quoted before any work starts.
AC repair in Boston covers two kinds of system — central (ducted) air and ductless mini-splits — and both fail in similar ways. We diagnose the actual fault first, explain it in plain terms, and quote the fix before the wrench comes out. Boston summers are short but humid, so a unit that can't keep up tends to show itself on the worst possible day.
Most "it runs but won't cool" calls come down to a handful of causes: low refrigerant from a leak, a failed capacitor or compressor, ice on the coil from restricted airflow or a dirty filter, or a thermostat that's reading wrong. We carry the common parts, so a lot of repairs are done in a single visit instead of a return trip.
Central systems and mini-splits share refrigerant and electrical fundamentals but fail differently — a mini-split might be a bad outdoor board or a clogged condensate line, where a central system is more often airflow or a capacitor. We service both. One note worth knowing: older systems run on R-410A refrigerant, which we still service, while new equipment uses next-generation refrigerants (R-32 or R-454B) as the industry transitions — it doesn't change your repair, but it matters if you're weighing repair against a new system.
As a rule of thumb, a system under about 10–12 years is usually worth repairing, while an older unit facing a major failure like a compressor is where a new AC installation or a heat pump enters the conversation. We give you the honest math, not a sales pitch. Heat the issue instead? See our furnace and heating repair, or browse all our Boston HVAC services.
Usually, yes. We keep same-day slots for air conditioning repair and run 24/7 for cooling emergencies across Greater Boston, especially during a heat wave.
