AC Repair & Diagnostics

Blowing warm, short-cycling, tripping the breaker, leaking water or making a noise it never made before — we diagnose the whole system before quoting a single part.

  • Refrigerant leak detection, recovery and recharge (EPA 608 certified)
  • Capacitor, contactor, relay and control-board replacement
  • Compressor and condenser fan-motor diagnosis
  • Evaporator coil cleaning and frozen-coil repair
  • Condensate drain clearing and overflow-switch repair
  • Thermostat faults and wiring troubleshooting

AC Installation & Replacement

An oversized system short-cycles, never dehumidifies and dies early. We run a Manual J load calculation on your actual house — square footage, insulation, windows, orientation — then size the equipment to it.

  • Manual J load calculation, not a rule-of-thumb guess
  • High-efficiency and variable-speed options explained side by side
  • City permit pulled and inspection scheduled by us
  • Old equipment removed and responsibly disposed of
  • Utility and federal rebate paperwork prepared for you
  • 2-year labour warranty on top of the manufacturer warranty

Residential · Safety first

Heating & Furnace Service

Gas furnaces, heat pumps and wall heaters. Every heating visit includes a combustion safety check — a cracked heat exchanger is not something to find out about in January.

  • Furnace repair, tune-up and full replacement
  • Heat-exchanger inspection and carbon-monoxide testing
  • Ignitor, flame sensor, inducer motor and gas-valve service
  • Heat pump diagnosis, defrost-cycle and reversing-valve repair
  • Wall and floor heater service
  • Smart thermostat supply and setup

Ductless Mini-Split Systems

The right answer whenever running ductwork isn't practical: garage conversions, ADUs, second storeys, sunrooms and that one bedroom that's always five degrees off.

  • Single-zone and multi-zone system design
  • Wall, ceiling-cassette and low-wall indoor head options
  • Inverter heat pumps — heating and cooling from one unit
  • Tidy line-set routing and exterior line-hide covers
  • Very high SEER ratings and genuinely quiet operation
  • Repair and service for mini-splits installed by others

Ductwork Repair, Sealing & Replacement

A leaky duct system can throw away a quarter of the air you paid to cool. In older South Bay homes we routinely find crushed flex, disconnected boots and undersized returns.

  • Duct leakage testing and static-pressure measurement
  • Sealing, re-strapping and insulation upgrades
  • Full duct replacement and system redesign
  • Return-air sizing corrections for weak airflow
  • New registers, grilles and zoning dampers
  • Duct cleaning and sanitising

Indoor Air Quality

Between the 405, the 110 and the port traffic, South Bay air brings a lot indoors. Filtration and ventilation upgrades make a difference you can measure — and usually feel within a week.

  • MERV 13+ media filter cabinets sized for your blower
  • Whole-home air purifiers and UV-C coil treatment
  • Humidity control and ventilation balancing
  • Allergen and dust-reduction assessments
  • Smart thermostats with air-quality monitoring
  • Filter subscription so you never forget a change
