Heating and Air Conditioning questions, answered by experts

A new HVAC unit typically adds about $2,500 to $3,000 to the value of your home or about 5% to 7% of your home’s value. Since a new unit can cost up to or more than $10,000 to install, it’s up to you to decide if the upfront cost is worth the added value. Consult a local AC installer to determine next steps.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.
