Heating and Air Conditioning questions, answered by experts

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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

AC capacitors last between five and 15 years, with an average lifespan of 10 years. Most people only need to replace a capacitor once during an AC unit’s lifetime. You don’t need to replace the capacitor unless something is wrong with it, which an HVAC repair pro can diagnose. 

You should have your HVAC serviced at least once per year. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between $100 and $550 for HVAC maintenance, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services.
