"Very professional and meticulous with his work. He layer down a plastic sheet where he worked. He even pulled out the pellet stove out of the Fire place and cleaned behind it. I believe we have used him for 3 years now. I would not use any one else! For the work he accomplished his price was very reasonable."

Heating and Air Conditioning FAQs, answered by experts

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

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
