Heating and Air Conditioning questions, answered by experts

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

Freon circulates through your AC unit in a closed loop, so ideally, all of it should remain inside your system and never need to be replaced. However, if your AC starts leaking Freon (which is common), you’ll need to top it up. Known as an AC recharge, the cost of adding refrigerant to your air conditioner depends on the size and type of the AC unit, as well as the type of refrigerant.

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.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Yes, unfortunately, scorpions do come up through air vents on occasion if they’re not properly sealed. These pests are excellent at finding small openings and may use vents as a pathway to cooler areas inside, especially during hot weather. To prevent this, inspect your vents, seal any gaps, and install fine mesh screens where necessary.
