Heating and Air Conditioning questions, answered by experts

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

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.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.
