Heating and Air Conditioning questions, answered by experts

It depends on the number of zones and rooms and how sophisticated the system is. On the low end, a ductless AC system costs $2,000 for one or two zones in one room. Covering two zones for more rooms can cost $6,000 to 8,000. If you want a larger ductless AC system to cover your entire home, multi-zone systems cost upwards of $13,000.

Poor cooling, unusual noises, or frequent cycling are indicators that professional service is needed.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

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.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
