Heating and Air Conditioning questions, answered by experts

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
