Mini Split Repair, Upton MA

Common Problems We See

Not heating or cooling right

Sometimes that’s a low refrigerant charge, a coil that’s caked with dirt, or a reversing valve that’s given up. We test pressures, clean what needs cleaning, and change only what’s bad.

Water coming out inside

That’s usually a clogged drain line or a cracked drain pan. We clear the blockage, make sure the line drains downhill like it should, and seal the wall sleeve so water stays outside.

Electrical issues

If the breaker keeps tripping or the unit’s completely dead, we check voltage, wiring, and control boards before we decide a part needs replacing.

Poor airflow or odd noises

Dirty filters, fans out of balance, or worn bearings can cause both. We clean, balance, and lubricate moving parts so the system runs quieter and pushes air like it should.

Mini Split Systems We Work On

We handle single-zone wall units in bedrooms and offices, multi-zone setups serving the whole house, and floor or ceiling cassettes tucked away behind panels.

Single-zone wall units

These are common in bedrooms, home offices, or small additions. They need regular filter cleaning and the occasional refrigerant check to keep them running right.

Multi-zone systems

These feed several rooms from one outdoor unit. If one zone quits, it usually takes some refrigerant balancing or control board work to get everything back in sync.

Floor and ceiling cassettes

We service these hidden units by opening up access panels, cleaning the drain pans, and making sure the fans and filters are in good shape.

Cold-climate heat pumps

Built to run all year, these can ice up or stall in the middle of winter. We check the defrost cycle, sensors, and refrigerant levels to keep them moving heat when it’s frigid out.

How We Go About Repairs

1. Look it over – We check filters, coils, and drains, then run it in heat and cool to see what it’s doing.
2. Test it – Gauges and a meter tell us refrigerant levels, electrical readings, and where the fault really is.
3. Fix it – Could be flushing a drain, cleaning coils, swapping a sensor, or adding refrigerant.
4. Double-check – We make sure temperatures, airflow, and electrical readings are back where they should be.

We leave you knowing exactly what we did and what to watch for next.

Keeping Your Mini Split Running

A ductless system will serve you for years if you give it a little attention. We tell our customers to clean or replace the filters every month during heavy use.

That keeps dust and pet hair from choking the airflow and overworking the fan motor.

Twice a year, it’s smart to rinse the indoor coil and flush the drain line. In Upton, spring pollen and fall leaves are the two big troublemakers. If they build up, you’ll see reduced cooling and—worse—water dripping inside.

Once a year, have us check the refrigerant charge, test the electrical components, and inspect the outdoor unit for signs of wear. A quick tune-up in the shoulder seasons often saves you from a breakdown when it’s sweltering or freezing.
