AC Repair

Warm air from the vents, an outdoor unit that hums but won't start, ice on the refrigerant line, water pooling by the indoor coil — we see the same failures every summer and carry the parts behind most of them: capacitors, contactors, fan motors. Most repairs finish in one visit, with a quote before we touch anything. Our AC repair page covers the symptoms worth a call and what to check yourself first.

Central AC Installation & Replacement

When a system passes 12 to 15 years and the repair bills start stacking, replacement usually wins the math. We size the new system with a load calculation instead of copying the old label, because oversized AC cools fast but leaves the house clammy — it never runs long enough to wring out the humidity. Estimates on system replacements are free. Our central AC installation page walks through sizing, the timeline, and what a swap involves.

Ductless Mini-Splits

Ductless mini-splits cool the houses ductwork never reached: antique homes on boiler heat, finished attics, additions, the bonus room over the garage. One outdoor unit feeds quiet wall units in the rooms you pick, and the cold-climate models heat too, which takes load off a boiler in the shoulder seasons. We install and repair them. Our ductless mini-split page shows how a layout comes together.

AC Tune-Ups & Maintenance

A spring tune-up costs less than the July breakdown it prevents. We clean the coils, check the refrigerant charge, test the capacitor before the first heat wave finds the weak one, and clear the condensate drain that would otherwise drip through a ceiling in August. Book an AC tune-up in April or May, before the first hot week fills the schedule.

Heat Pumps Cool, Too

A heat pump is an air conditioner that runs in both directions, and the ones we install cool exactly like central AC in July. If your cooling and heating equipment are both due for replacement within a few years, one heat pump can take over both jobs. That option lives on our heat pump installation page under heating.

Frequently Asked Questions

Is central air worth it in New England for a couple months of summer?
For most homes, yes, and humidity is the real argument. Summers here have gotten hotter and stickier, and AC's biggest job in Massachusetts is drying the house out, which fans can't do. Buyers expect cooling now too, so a house without it shows its age. A right-sized system costs little to run for the weeks it works.
Central AC or ductless — which is right for my house?
It comes down to ductwork. If the house has ducts in decent shape, central AC uses them and cools everything at once. No ducts, or just two or three problem rooms? Ductless mini-splits skip the ductwork entirely. Older boiler-heated homes almost always land on ductless.
What should I check before hiring an AC company?
Four things: licensing and insurance (we're licensed, insured, and EPA certified for refrigerant work), whether they size by load calculation rather than guessing from the old unit, a local track record you can verify, and a written quote before work starts. Anyone who fails one of those, keep looking.
I got a big repair or replacement quote — is a second opinion worth it?
Yes, and nobody reasonable is offended by it. Compressor replacements and full-system verdicts are exactly where second opinions pay off. An honest second look means gauges on your actual equipment, a diagnosis explained in plain English, and a written number to compare. We do them regularly.
