What we do
From a failed capacitor to a full system replacement, Covina HVAC pros handle it all — AC, heating, air quality, residential and commercial.
Boilers last decades, but controls, circulators, and expansion tanks do not. In Covina, we diagnose boiler issues properly — combustion, water side, and controls — and repair only what is failing. Call (877) 317-0473, answered 24/7 in winter.
Considering AC replacement in Covina? We walk you through sizing, SEER2 ratings, and what the long-term math looks like — then install it right, with a written scope before work starts. Call (877) 317-0473.
Dust, allergens, wildfire smoke, pet dander — Covina indoor air carries more than you think. We assess your home's air and install the right combination: high-MERV filtration, UV treatment, humidifiers, and dehumidifiers matched to your system.
Not every warm-air complaint needs a new system. Our Covina AC repair techs test first — electrical, refrigerant charge, airflow, thermostat — and repair only what is actually failing. Free quote before any work begins.
Dust storms out of every vent, musty smells when the system kicks on, or rooms that never get comfortable — Covina duct cleaning removes years of buildup so your system breathes easier and your air runs cleaner.
No cooling in a heat wave or no heat in a freeze is an emergency — full stop. Our Covina emergency HVAC line is answered 24/7, with techs dispatched around the clock for no-heat and no-cool calls.

A smart thermostat only saves money if it is wired and configured correctly for your equipment. Our Covina techs install and program thermostats to match your furnace, AC, or heat pump — and show you how to use the schedules.

California HVAC is a two-front battle: relentless summer heat that runs air conditioners for months, and wildfire smoke season that turns indoor air quality into a health issue. In Covina, our network sizes AC systems for real peak loads — not averages — and pairs them with high-filtration options and sealed ductwork so smoke stays outside where it belongs. Heat plus smoke is the local reality; your system should be built for both.
The cheapest quote is rarely the cheapest system. In Covina, proper installation — real load calculation, correct refrigerant charge, sealed ductwork — is what delivers the full 12–15 year equipment lifespan. 2026 ranges: repairs from $350–$800 for AC; replacements $3,500–$12,000.
