Heating and Air Conditioning questions, answered by experts

Signs that your air conditioner capacitor is malfunctioning include a smell or smoke coming from the unit, a humming or banging noise when it starts, the system shutting off randomly, higher energy bills, and no cold air blowing out of the unit. Additionally, if your capacitor is bad, the air conditioner may not turn on at all. 

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.
