Frequently Asked Questions

Call right away when the house is becoming unsafe — no heat in freezing weather, no AC in extreme heat, a gas smell, water flooding, or a breaker that will not reset. If you can manage with fans or blankets and it is merely uncomfortable, it can usually wait for a same-day or next-day appointment.

Emergency service outside normal business hours may include an after-hours fee, but we always explain pricing before any work begins. When a problem can wait for regular hours, we tell you honestly rather than charging emergency rates.

Consider the age of the system, how often it has needed repairs, its performance, and the cost of the current repair. If repairs are becoming frequent or a major component has failed, replacement may be worth discussing. A professional evaluation compares the practical options.

A good rule is twice a year — once before the cooling season and once before the heating season. At minimum, schedule a professional checkup once a year.

Correct sizing comes from a load calculation that accounts for square footage, insulation, windows, and climate — not guesswork. A system that is too big short cycles, and one that is too small runs constantly. We include sizing in any installation evaluation.

A furnace burns fuel (or uses electric heat) to warm the air. An air handler is the indoor unit of a heat pump or AC that moves air over the coil — it does not generate heat on its own. Both use a blower to push air through the ducts.

Yes. A blank screen, dead batteries, or a wiring problem can stop the thermostat from calling for cooling — and the system will not start. Replacing the batteries and checking the breaker are the first steps; if the screen stays blank, a technician can check the thermostat and wiring.

The most common causes are a thermostat on the wrong setting, a dirty air filter, a frozen coil, low refrigerant, or a failing compressor. Start with the thermostat and the filter; if it still blows warm air, a technician should check the system.
