Heating and Air Conditioning FAQs, answered by experts

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again.
