Heating and Air Conditioning questions, answered by experts

Assessing location for airflow, convenience, and minimal noise impact.

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

If you have the luxury of waiting a bit to replace your unit, they can drop in price depending on the time of year. Air conditioning units often go on sale in the fall after they’re not as in demand when the temps drop outside. Same with furnaces—prices drop in the spring when it starts getting warmer.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

It's recommended to change HVAC air filters every one to three months. The frequency depends on factors such as filter type, indoor air quality, and whether there are pets or people with allergies in the household. Regular filter changes maintain proper airflow, improve indoor air quality, and ensure efficient HVAC system operation.
