AC Maintenance & Tune-Ups
Nobody thinks about air conditioning until the first ninety-degree day, which is exactly when every contractor on the South Shore is booked solid. A spring tune-up finds the weak refrigerant charge and the clogged drain in April, on your schedule instead of during a heat wave.
If your system is low on refrigerant, it has a leak. Refrigerant is not consumed like fuel. Anyone who tops you off every spring without finding the leak is selling you the same repair annually—and venting refrigerant along the way. We look for the leak.
What We Actually Do
A cooling tune-up should be measurements, not a visual once-over and a filter. Here is the work, so you can compare it against whatever a $59 coupon is buying elsewhere.
Refrigerant & performance
Superheat and subcooling measured with gauges, temperature split across the coil, and a leak check if the numbers are off. That is how you know a system is actually charged correctly.
Coil cleaning
Outdoor condenser coil washed of pollen, grass and cottonwood, indoor evaporator inspected. A blocked condenser makes the compressor work harder for less cooling all season.
Condensate & safeties
Drain line cleared and flushed, pan checked, float switch tested. This one item prevents more water damage claims than anything else on the list.
Electrical
Capacitor tested against rating, contactor inspected, amp draw compared to nameplate, connections tightened. A weak capacitor is cheap now and a failed compressor later.
Airflow
Filter, blower wheel condition, and static pressure. Restricted airflow is the most common cause of a frozen coil, and freezing a coil repeatedly is how compressors die early.
Coastal rinse
In Scituate, Marshfield, Cohasset and Hull, salt air eats coils and cabinets. An annual freshwater rinse measurably extends the life of an outdoor unit near the water.
What You Can Do Yourself
Change the filter on a schedule—every one to three months for a one-inch filter, less often for a deep media filter. Keep two feet of clearance around the outdoor unit and pull the leaves and grass clippings off the fins. Hose the outside of the coil down gently in the spring.
One thing worth knowing: if the unit ices up, shut the cooling off and run the fan to thaw it before you call. Running a frozen system does real damage, and the coil has to be thawed before anyone can diagnose it anyway.
Already not cooling? Go straight to AC repair.
Common Questions
When should I schedule it?
April through May is ideal. Once the first real heat wave lands we are running emergency no-cooling calls and maintenance slots get pushed. Booking early also means a repair, if you need one, happens before you are sitting in the heat waiting on a part.
My mini-splits—do those need service too?
Yes, and they are frequently neglected because they run so quietly. The indoor blower wheels and drain pans accumulate biofilm—that is what causes the musty smell people notice in year three. A proper deep cleaning solves it. See ductless services.
Is it required for my warranty?
Most manufacturers condition their parts warranty on documented annual service. If a compressor fails in year six and there are no records, expect that claim to be denied. We document every visit.
Do you have a maintenance plan?
Yes—it bundles your cooling visit in spring and your heating visit in fall, puts you ahead of non-members when the weather turns, and includes a discount on repairs. Ask when you call.
