Heat Pump Maintenance and Tune-Ups in Philadelphia and the Suburbs

A heat pump heats your home all winter and cools it all summer, so it works roughly twice as many hours as a furnace or an air conditioner alone. That’s why heat pumps need professional maintenance twice a year: a fall tune-up before heating season and a spring tune-up before cooling season. Regular heat pump servicing keeps your system efficient, catches worn parts before they fail on the coldest night of the year, and keeps your expensive backup heat from running more than it should.

Every EMCO Tech heat pump tune-up includes:

A full inspection of the outdoor unit, indoor air handler, and controls
Coil cleaning, electrical testing, and refrigerant performance checks
A defrost cycle test and backup heat check before winter
A written list of anything that needs attention, with the price before any work starts

We maintain central ducted heat pumps, cold-climate inverter heat pumps, and dual-fuel systems across Philadelphia, Montgomery, Bucks, Chester, and Delaware counties. Call 215-366-1001 or book your heat pump tune-up online.

What’s Included in a Heat Pump Tune-Up

Outdoor Unit

Clean the outdoor coil and clear leaves, grass, and debris from around the unit
Inspect the fan motor and blades, and check that the unit sits level on its pad
Test the capacitors, contactor, and electrical connections for wear and heat damage
Check refrigerant pressures and temperatures to confirm the system is charged and performing correctly
Run the system in heating and cooling to confirm the reversing valve switches modes
Test the defrost control and sensor so the coil clears ice properly in winter

Indoor Air Handler

Inspect and replace or clean the air filter
Check the blower motor, wheel, and airflow
Inspect the indoor coil and flush the condensate drain line and pan
Test the backup heat strips or furnace so they come on only when they should
Measure the temperature split across the coil in both heating and cooling

Thermostat and Controls

Verify thermostat settings, staging, and the backup heat lockout temperature
Check that the system isn’t running on auxiliary or emergency heat when it doesn’t need to
Review the control board for stored fault codes

If we find a refrigerant problem, we look for the leak instead of just topping it off. If something needs repair, you get a plain explanation and the price first, and our heat pump repair technicians can usually fix it the same visit.

How Often Should a Heat Pump Be Serviced?

Twice a year. Because a heat pump runs for heating and cooling, it should be serviced in the fall before heating season and in the spring before cooling season. In the Philadelphia area, where heat pumps run nearly year-round through humid summers and freezing winters, skipping a season is when small problems turn into breakdowns. Many manufacturer warranties also require regular professional maintenance, so keep your service records.

Book Your Heat Pump Tune-Up

Fall is the time to get your heat pump ready for winter. Our technicians test defrost, backup heat, and refrigerant performance so you're not stuck on expensive emergency heat in January. Ask about a maintenance plan that covers both seasons.

Fall Heat Pump Tune-Up: Get Ready for Winter

The fall tune-up is the most important one. Cold weather is when a heat pump works hardest, and it’s when a weak capacitor, a failing defrost sensor, or a backup heat problem shows up. We make sure the defrost cycle clears the outdoor coil, the auxiliary heat strips or furnace come on only below the right outdoor temperature, and the thermostat isn’t calling for expensive emergency heat when the heat pump can handle the load. A heat pump that leans on backup heat all winter can make your electric bill climb fast. Our guide to aux heat and cold-climate heat pumps explains why.

Spring Heat Pump Service: Ready for Cooling

The spring visit gets the system ready for summer. We clean the outdoor coil after a winter of debris, check refrigerant performance in cooling mode, clear the condensate drain before humid weather, and test the capacitors and contactor that take the most strain on hot days.

Signs Your Heat Pump Needs Service Now

The outdoor unit stays covered in ice instead of defrosting
The system runs on auxiliary or emergency heat often, or your electric bill jumps
Air from the vents feels lukewarm in heat mode
The heat pump short cycles, runs nonstop, or makes new grinding, buzzing, or rattling noises
Some rooms are much colder or warmer than others

If your heat pump isn’t working at all, skip the tune-up and schedule heat pump repair.

Heat Pump Maintenance Plans

The easiest way to stay on schedule is a heat pump maintenance plan. We remind you when each visit is due, handle both seasonal tune-ups, and plan members get priority scheduling and member savings on repairs. A maintenance plan also keeps the service records your manufacturer may ask for if you ever need a warranty claim.

Heat Pump Maintenance FAQs

How often should a heat pump be serviced?

A heat pump should be serviced twice a year: in the fall before heating season and in the spring before cooling season. Because it heats and cools, a heat pump runs far more hours than a furnace or air conditioner alone. In the Philadelphia area, where heat pumps run nearly year-round through humid summers and freezing winters, twice-a-year servicing is the best way to keep efficiency up and avoid breakdowns. If you can only do one visit, make it the fall tune-up, since winter is when a heat pump works hardest and when a failure is most disruptive.

What is included in heat pump maintenance?

A complete heat pump tune-up covers both the outdoor unit and the indoor air handler. Outdoors, we clean the coil, check the fan motor and blades, test the capacitors, contactor, and electrical connections, check refrigerant performance, and confirm the reversing valve and defrost control work. Indoors, we replace or clean the filter, check the blower and airflow, inspect the coil, flush the condensate drain, and test the backup heat. We also verify thermostat settings and the backup heat lockout so the system isn’t wasting money on emergency heat. You get a written list of anything that needs attention.

What's the difference between a heat pump tune-up and a heat pump repair?

A tune-up is preventive. It’s a scheduled visit to clean, test, and adjust a heat pump that’s working, so it keeps running efficiently and small problems get caught early. A repair fixes something that has already failed, like a heat pump that won’t heat, is covered in ice, is short cycling, or is blowing cold air. During a tune-up, our technician may find a worn part, such as a weak capacitor or a failing defrost sensor. When that happens, you get the price before any work starts, and most repairs can be handled during the same visit so you don’t need a second appointment.

How much does heat pump maintenance cost?

The cost of heat pump maintenance depends on the type of system, whether it’s a ducted heat pump, a cold-climate inverter system, or a dual-fuel setup with a furnace, how many systems you have, and whether you book a one-time tune-up or a maintenance plan. A maintenance plan is usually the best value because it covers both seasonal visits and adds priority scheduling and member savings on repairs. If our technician finds a problem during the tune-up, you get the repair price before any work starts. Call 215-366-1001 for current pricing on heat pump tune-ups and maintenance plans.

When is the best time to schedule a heat pump tune-up?

Schedule the heating tune-up in early fall, September through early November, before the first hard freeze, and the cooling tune-up in spring, March through May, before the first hot stretch. Booking early gets you a convenient appointment before the busy season, when schedules fill with no-heat and no-cooling calls. If your heat pump is already showing warning signs, like ice that won’t clear, frequent auxiliary heat, lukewarm air, or new noises, don’t wait for the next season. Have it checked now, because those problems usually get worse and more expensive the longer the system runs that way.

Do you service cold-climate and inverter heat pumps?

Yes. We maintain cold-climate inverter heat pumps, standard central heat pumps, and dual-fuel systems that pair a heat pump with a gas or oil furnace, on all major brands. Inverter systems run at variable speeds and rely on electronic controls and sensors, so maintenance includes checking those controls, the defrost settings, and the backup heat lockout so the system makes the most of its cold-weather performance. For dual-fuel systems, we also confirm the switchover point between the heat pump and the furnace is set correctly, which has a big effect on comfort and on your winter energy bills.

Do you offer heat pump maintenance plans?

Yes. Our maintenance plans cover both seasonal heat pump tune-ups each year, so your system gets serviced before heating season and before cooling season without you having to remember. We send a reminder when each visit is due, plan members get priority scheduling during busy weeks, and members save on repairs. A maintenance plan also builds a service history for your heat pump, which helps if you ever need a warranty claim and shows a future buyer that the system was cared for. Plans are available for homes with one system or several, including ductless and dual-fuel setups.

Do you offer commercial heat pump maintenance?

Yes. We provide scheduled heat pump maintenance for offices, retail stores, restaurants, and apartment buildings across Philadelphia and the suburbs, including rooftop and split heat pump systems. Commercial maintenance follows the same checklist as residential service, with visits scheduled around your business hours and a written report for each unit. Planned maintenance cuts down on emergency calls, keeps tenants and customers comfortable, and helps your equipment last longer. For buildings with several systems, our commercial HVAC maintenance plans bundle every unit into one agreement with priority service. Call 215-366-1001 to set up a site visit.
