What is the difference between a condenser and an evaporator?

A condenser rejects heat from the refrigerant into the outdoor air, while an evaporator absorbs heat from indoor air or a refrigerated space. Together they form the core of any HVAC or refrigeration system.

How do I choose the correct replacement coil?

Always match the refrigerant type, tonnage, metering device, coil configuration and OEM specifications. Incorrect matching can cause capacity loss, high head pressure and compressor damage.

Are microchannel coils better than fin-and-tube coils?

Microchannel coils offer higher efficiency and lower refrigerant charge, while fin-and-tube coils are easier to repair and more tolerant of minor system contamination.

Can evaporator coils be cleaned?

Yes. Evaporator coils should be cleaned regularly to prevent airflow restriction, ice formation and efficiency loss. Use appropriate coil cleaners based on aluminum or coated coil construction.

Common causes include corrosion, vibration, improper refrigerant charge, floodback, physical damage and formicary corrosion in copper-aluminum coils.

Evaporators & Condensers

The Condensers & Evaporators category covers the core heat-exchange components that allow HVAC and refrigeration systems to absorb and reject heat. Whether used in residential A/C, heat pumps, mini-splits, walk-in coolers or commercial refrigeration, these coils determine system efficiency, capacity and reliability.

Here you’ll find air-cooled condensers, evaporator coils, cased and uncased A-coil assemblies, mini-split indoor/outdoor coils, commercial refrigeration coils, replacement coil sections, OEM-matched coils, fin-and-tube coils and microchannel options. These components support split systems, packaged units, heat pumps, VRF/VRV systems, ice machines and walk-in evaporators.

Residential & light-commercial condensers for split A/C and heat pump systems.
Evaporator coils including A-coil, N-coil and slab designs.
Mini-split indoor and outdoor coils for service and replacement.
Commercial refrigeration coils for walk-ins, reach-ins and prep tables.
Microchannel & fin-and-tube coils for high-efficiency applications.

When selecting condensers or evaporators, verify refrigerant type (R410A, R32, R454B, R22, R134a, CO₂), tonnage/BTU rating, coil configuration, line-set sizing, connection type, airflow requirements, compatibility with the existing indoor/outdoor unit and OEM specifications. Matching components correctly ensures capacity, superheat stability and long-term compressor protection.

Pro tip: A mismatched coil or incorrect metering device can cause high head pressure, poor humidity control or compressor failure. Always verify the coil’s rating with the system’s refrigerant and tonnage.
