Coldharbour Heating & Air is the Poway HVAC company that puts every price and guarantee in writing before work begins. Poway’s inland heat, 30-degree overnight temperature swings, and older single-family housing stock create repair and replacement jobs that look very different from coastal San Diego work. Our technicians arrive in a firm window, hand you a fixed price, and back every repair with a 365-day written guarantee. If your AC or furnace quits in Poway, call (619) 793-3598 and a live person answers, day or night.
Why Poway Homes Are Different
Poway sits roughly 20 miles inland, where summer highs routinely push past 90°F while nights drop into the 60s. That 30-degree swing forces HVAC systems to cycle hard between high sensible cooling loads and cool nighttime heating, which is exactly the pattern that wears out capacitors, contactors, and heat pump reversing valves faster than coastal systems. Fall brings Santa Ana winds that coat condenser coils with fine dust and dried grass, cutting airflow and driving up head pressure on compressors. We see the result on service calls throughout Green Valley, The Heritage, and the Ranch-style streets off Espola Road.
The housing stock adds another layer. Most Poway homes were built between the 1970s and 1990s, with custom builds on large lots mixed in. Original flex duct in attics baked by decades of inland heat turns brittle and leaks conditioned air into unconditioned space. 1970s-era slab-on-grade copper refrigerant lines are prone to pinhole leaks that bleed charge slowly until the system can’t hold temperature on a 95-degree afternoon. Tile and low-slope roofs leave attics with limited access, so duct retrofits take more planning than in newer subdivisions. And on equestrian properties, condenser location matters: a noisy unit placed near a stall or paddock disturbs horses, so we position and spec units with that in mind.
Styles & brands we work with
Our Main Poway Services
Most Poway homeowners call us for two things: an AC that quit during a heat wave, or a furnace that won’t fire on a cool winter morning. The third call, AC replacement, usually starts as a repair estimate and becomes a conversation about what makes sense long-term. Each service has its own Poway page with pricing detail, sub-jobs, and what to expect.
AC Repair in Poway
Poway AC repair calls spike in July and August, when a system that ran fine in June suddenly can’t hold 78 degrees. We diagnose the actual fault before quoting a fixed price. Common Poway failures include heat-stressed capacitors, clogged condenser coils from Santa Ana dust, refrigerant pinhole leaks in older line sets, and blower motors worn from long daily runtimes in summer. Every repair comes with our 365-day guarantee in writing. Read the full breakdown on our AC Repair in Poway page.
Furnace Repair in Poway
Poway winters are mild, but nights in the low 40s and high 30s still send homeowners to the thermostat. Gas furnaces that sit idle for nine months often fail on first ignition: igniters crack, pressure switches stick, flame sensors foul with oxidation. Older Poway homes with original 1980s furnaces may need heat exchanger inspection more urgently, since slab foundations and tight attics accelerate corrosion cycles. Every furnace repair is priced before work starts and guaranteed for a full year. Details are on our Furnace Repair in Poway page.
AC Installation in Poway
Replacing an AC system in Poway means matching the unit to a climate with wild daily swings and homeowners who value quiet, especially near horses. Variable-speed and dual-fuel systems handle both the 95-degree afternoons and the 45-degree nights without short-cycling or blasting noise across a large lot. Ductwork condition matters here, since 30-year-old flex duct in a baked Poway attic can waste a third of the cooling a new system produces. We scope the whole job, then hand you a fixed written price before ordering equipment. See AC Installation in Poway for the full scope and pricing.

What Poway Customers Say
"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
- Doug Feeney"Signed up for a tune up before summer. He found a part starting to fail and showed me the reading, didn't just tell me to trust him. Fixed it then so we wouldn't get stuck in July."
- Sophia Tran"Our upstairs never cooled right. He found the duct run was half blocked and the system low on charge, fixed both, and now the whole house is even. Explained every step."
