Heating and Air Conditioning questions, answered by experts

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn’t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.
