Well, A/C is 10 years old, they did an inspection and evaluation. The capacitor was in need of replacement and was probably costing us in higher electric bills. Also they installed a programmable thermostat for us. We were very pleased.

Heating and Air Conditioning questions, answered by experts

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

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.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.
