Latest From Our HVAC Experts
Why Won’t My Heat Pump Switch From Cooling to Heating?
Thermostat on HEAT but it still feels like the AC? Sometimes it’s the O/B setting or wiring, sometimes the reversing valve—and sometimes the heat pump is heating normally. Here’s how to tell before replacing parts.
How Do I Know If My Heat Pump Has a Refrigerant Leak?
Refrigerant isn’t fuel — a heat pump shouldn’t “use it up.” If yours is low, that usually means a leak. Here are the warning signs, why topping off isn’t a repair, and how leaks are properly found and fixed.
Can I Use Any Smart Thermostat With a Heat Pump?
“It’s smart, so it’ll work” isn’t how heat-pump thermostats go. The thermostat has to control the reversing valve, staging, aux/emergency heat and sometimes communicating equipment. Here’s how to check compatibility before you swap.
Can a Heat Pump Cool Your Home in 100°F Weather?
In summer a heat pump works just like a central AC—so yes, a properly selected one cools in triple-digit Temecula heat. How well depends on sizing, cooling capacity, ductwork, airflow and installation.
Why Is My Heat Pump Covered in Frost or Ice?
Light frost on a heat pump is often normal—the defrost cycle clears it. Heavy ice that stays is not. Here’s how to tell the difference, why steam during defrost is normal, and when icing means you need service.
Single-Stage vs. Two-Stage vs. Variable-Speed Heat Pumps
Single-stage, two-stage, variable-speed—”premium” isn’t automatically the right answer. Here’s how each heat-pump type actually operates, the real differences in comfort, noise, efficiency and cost, and how to decide.
What Size Heat Pump Do I Need for My Home?
“How many tons do I need?” isn’t answered by square footage. Two identical-size homes can need very different capacity. Here’s what actually determines proper heat-pump sizing—and why a load calculation beats a rule of thumb.
Why Does My Heat Pump Run Constantly? Is It Normal?
Heat pumps often run longer than a gas furnace did—and with variable-speed equipment, nearly all day can be normal. Here’s how to tell steady, efficient operation from a heat pump that can’t keep up.
