If your house feels sticky even though the air conditioner is running, you are not imagining it. Comfort depends on controlling both temperature and humidity.

HVAC maintenance matters a lot, but it is also easy to oversell. Maintenance is important because it helps the system stay cleaner, run more efficiently, and reveal problems earlier.

If you see ice on your air conditioner, frozen refrigerant lines, or a system that stops cooling after running for a while, your AC may be freezing up.

If your energy bill suddenly jumped, your HVAC system is one of the first places to look. That does not always mean something is broken, but it often means something changed.

Your AC and heater do completely different jobs. They need to be checked at different times of the year, when we can actually test what they’re designed to do.
