Hannon Heating & Air Conditioning runs pre-season central AC tune-ups in Bellingham, MA and the MetroWest towns around it. Book in spring, before the first heat wave fills the schedule with no-cool calls. One visit, clearly scoped, no contract to sign — and you'll know what we found before we leave. We run tune-ups in Milford, Wrentham, and Norfolk as well as Bellingham.

What's in the Tune-Up: The Whole List

The reputation problem with AC tune-ups is the fifteen-minute visit that ends in a sales pitch, so here is exactly what ours covers. We clean the condenser coil so the system can shed heat. We check refrigerant pressures against the manufacturer's targets. We test the run capacitor and check amp draws on the compressor and fan motors, plus the contactor and wiring. We flush the condensate drain so the float switch doesn't shut the system down in July. And we finish by verifying airflow, filter condition, and thermostat operation. You get told what we found either way, including when everything checks out. If the visit does turn up a failing part, we quote the AC repair before touching anything, and you're free to say no.

  • Condenser coil: cleaned so the system can shed heat.
  • Refrigerant pressures: checked against the manufacturer's targets.
  • Run capacitor: tested; amp draws checked on the compressor and fan motors, plus the contactor and wiring.
  • Condensate drain: flushed so the float switch doesn't shut the system down in July.
  • To finish: airflow, filter condition, and thermostat operation verified.

Does a Yearly Tune-Up Genuinely Save Money?

Yes, three ways, and none of them are dramatic. A condenser coil caked with a year of pollen and cottonwood fluff makes the compressor work harder for the same cooling; cleaning it buys that efficiency back. The failures that strand people in heat waves, weak capacitors and clogged drain lines, are quick to catch in May and a sweaty wait in July, when every company's schedule is full. And most equipment manufacturers require documented annual maintenance to keep the compressor warranty valid, so the visit doubles as your paper trail. Fall works the same way on the heating side: a heating tune-up before the cold, an AC visit before the heat, one company covering both.

What You Can Do Yourself Between Visits

Three things, all easy. Swap the filter every one to three months during cooling season, because a packed filter is the quickest way to freeze a coil. Keep the condenser clear: two feet of open space around the outdoor unit, no shrubs grown into it, and a gentle rinse with the hose when pollen cakes the fins. And pour a cup of white vinegar into the condensate line's access tee once a season to keep algae from clogging it. Do those and the annual visit mostly confirms good news. Spring slots fill first, so book yours before the first stretch of ninety-degree days.

Frequently Asked Questions

How often does central AC really need professional service?
Once a year, in spring, before the cooling season starts. That timing catches winter's damage (chewed wiring, a weakened capacitor, a coil full of debris) while repair schedules are still open. Most of our customers pair it with a fall heating tune-up, so the whole system gets looked at twice a year by the same company.
What's included in your tune-up — is it more than a quick look?
It's a working visit with a fixed list: condenser coil cleaning, refrigerant pressure check, capacitor and electrical testing, condensate drain flush, and airflow and thermostat verification. You hear what we found either way, including when everything checks out. Anything beyond the list gets quoted before we touch it.
Does a yearly tune-up genuinely save money or is it an upsell?
It pays for itself in ordinary ways: a clean coil cools more efficiently, small parts like capacitors get caught before they strand you in a heat wave, and the service record keeps your manufacturer's compressor warranty valid. We sell it as a single visit, no contract, so there's nothing to cancel.
What can I do myself between visits?
Three jobs are safely yours: change the filter every one to three months, keep two feet of clearance around the outdoor condenser and rinse its fins gently with a hose, and pour a cup of white vinegar down the condensate drain's access tee each season. Leave refrigerant and electrical work to us — that's where the licensing matters.
