Be honest: have you changed your air filter in the last 3 months?
Replacing a dirty air filter is one of the easiest ways to help your HVAC system run more efficiently. A clean filter can improve airflow, support better indoor air quality, and reduce unnecessary strain on your equipment. If you need assistance with yours, contact us today.

Myth: Turning your thermostat way down cools your house faster.
Fact: Your air conditioner cools at the same rate no matter what temperature you set. Lowering it too much just makes your system run longer than necessary.

Does it feel like you're walking into a different climate when you go upstairs at home?
You're not imagining it. Hot air naturally rises, which is why second floors stay warmer during the summer. Other common causes include poor airflow, inadequate insulation, blocked vents, or an HVAC system that's not properly balanced.
If your upstairs never seems to cool down, we can help identify the cause and recommend solutions to improve comfort throughout your home. Chat with us today: https://fossheating.com/contact/
