How a heat pump works

One system can do both jobs.

hot refrigerant cool refrigerant

Reversing valve — the part that flips the seasons.

In summer — Cooling

Right now it's an air conditioner: heat is being pulled out of the house and thrown away outside.

  1. 1 Absorb. Refrigerant in the indoor coil soaks up heat from your indoor air — the blower pushes the now-cooler air through the ducts.
  2. 2 Compress. The compressor squeezes the refrigerant, concentrating that heat.
  3. 3 Release. The hot refrigerant dumps its heat outdoors through the outdoor coil — that's the warm blast you feel next to the unit.
  4. 4 Expand & repeat. The refrigerant expands, chills back down, and heads inside for more.

In winter — Heating

Now it's a heater: the same machine grabs heat from the outdoor air and pushes it inside.

  1. 1 Absorb. Refrigerant in the outdoor coil soaks up heat from the outside air — yes, even a 48° morning holds plenty of heat energy.
  2. 2 Compress. The compressor squeezes the refrigerant, which raises its temperature sharply.
  3. 3 Release. The now-hot refrigerant releases that heat into your air at the indoor coil, and the blower sends it through the house.
  4. 4 Expand & repeat. The refrigerant expands, cools, and heads back outside for more.

How AC Actually Works

Air conditioning doesn't make cold. It moves heat.

Follow the refrigerant loop between the indoor coil and the outdoor condenser — four stages, repeating all summer. Once you see it, sizing and maintenance decisions make sense.

The air conditioning refrigeration loop A house wall separates indoors from outdoors. Inside, warm room air passes over the evaporator coil and comes off cooled. The refrigerant line carries absorbed heat out through the wall to the compressor and condenser coil in the outdoor unit, where a fan rejects the heat to the outside air. The refrigerant returns through the expansion valve, completing the loop. INDOORS OUTDOORS evaporator coil warm room air cooled air out condenser + fan compressor your house's heat, leaving expansion valve 1 2 3 4
  1. 1

    The indoor coil absorbs heat

    Warm house air blows across the evaporator coil; cold liquid refrigerant inside boils and soaks the heat up. The air comes off the coil cooled — that's the 'cold air'.

  2. 2

    The compressor squeezes it hotter

    The outdoor unit's compressor squeezes the heat-laden vapor to a high pressure — concentrating the heat so it's hotter than a SoCal afternoon.

  3. 3

    The condenser dumps the heat outside

    The fan pulls outdoor air across the condenser coil and your house's heat pours out into the yard. That hot breeze off the top of the unit is heat that used to be in your living room.

  4. 4

    The refrigerant resets and repeats

    An expansion valve drops the refrigerant's pressure and temperature, and the loop starts again — around and around, all summer.

Air Conditioning questions, answered

How do I know if my AC needs to be replaced instead of repaired? +

Age is the biggest factor: systems over 10–15 years old that need frequent or costly repairs, cool unevenly, or drive rising energy bills are usually better replaced. If your unit still uses phased-out refrigerant, that also tips the scale. We'll give you a repair quote and a replacement quote so you can compare real numbers.

How often should I have my AC serviced? +

At least once a year, ideally in spring before the heat arrives. A professional tune-up cleans coils, verifies refrigerant charge, calibrates the thermostat, and catches small problems before summer's first heat wave turns them into breakdowns.

What size AC does my home need? +

It depends on square footage, insulation, window exposure, and ductwork — not just the size of your old unit. We perform a proper load calculation on every installation, because an oversized or undersized system costs more to run and wears out faster.

Do you offer financing on new AC systems? +

Yes — we offer flexible financing options through trusted lending partners, subject to credit approval. Ask about current plans when you get your free estimate.
