Heating and Air Conditioning questions, answered by experts

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

Extreme outdoor conditions, like high humidity or extensive salt spray
Improper installation
Extended run times, either by the unit being too small or the thermostat setting too low
Not performing required maintenance

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.
