Heating and Air Conditioning questions, answered by experts

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the “reset” button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn’t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to “cool” to test the system.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

Yes, ductless AC adds value to your home. Fixing or replacing traditional ductwork is an incredibly expensive and daunting prospect. Traditional ducts can be noisy and temperamental, with the potential for unwanted guests like hornets and rodents. Ductless mini-splits eliminate a major hassle and expense, so they can increase a home's value.
