What we work on

Blue is cooling, orange is heating — the same crew does both.

Cooling

AC repair & replacement

Diagnostics, refrigerant, compressors and full system swaps when a repair no longer pays.

Heating

Furnace repair & replacement

Ignition, heat exchangers and safety checks, plus replacement when a unit is past it.

Cooling

Seasonal tune-ups

A full service before the season turns, so the failure happens on our visit and not in a heatwave.

Heating

Ductwork & airflow

Leak sealing, balancing and returns — usually why one room never gets comfortable.

Cooling

Indoor air quality

Filtration, humidifiers and ventilation for allergies and dry winter air.

Heating

Thermostats & controls

Smart thermostat fitting and zoning, set up properly rather than left on defaults.

Two tune-ups a year

Once before summer, once before winter. It is the whole reason systems reach their design life.

Before summer

Cooling tune-up

  • Coil clean and refrigerant check
  • Condensate drain cleared
  • Airflow and thermostat calibration

Before winter

Heating tune-up

  • Heat exchanger inspection
  • Burner clean and ignition test
  • Carbon monoxide safety check

Why homeowners call us back

  • Technicians on call 24/7 for no-heat, no-cool and safety emergencies.
  • We quote the repair and the replacement, and tell you which one we would actually choose.
  • Licensed, insured, and we put drop cloths down in your house.
  • Two tune-ups a year is the recommendation, not an upsell — it is how systems last.
