Your heating and cooling system moves all of the air in your house many times a day, so it is the natural place to clean that air. North Texas brings plenty to filter: spring and fall pollen, cedar season, dust and pet hair. AC and Heat LLC helps homeowners in Wylie, Rockwall, Plano, Garland and nearby cities choose the right filters and air purification for their system.
Start with the filter
Filters are rated by MERV. A higher MERV number catches smaller particles, but a very dense filter can restrict airflow on a system that wasn't designed for it. That can make the system work harder, freeze up or cool poorly. We can check your system and recommend a filter that balances clean air and good airflow.
- Check the filter monthly and replace it every one to three months
- Change it more often if you have pets, allergies or a remodel in progress
- Make sure the airflow arrow points toward the unit and the filter fits snugly
- Write the size down. It is printed on the edge of the old filter
Air purification options
Beyond standard filters, we can talk through air purification options that work with your existing system. We will explain what each one does and what upkeep it needs, so you can decide what fits your home and budget.
Other things that affect indoor air
Leaky return ducts in the attic can pull hot, dusty air into the system. A dirty coil or clogged condensate drain can lead to musty smells. Humidity matters too: a system that is oversized or low on refrigerant may not remove enough moisture in summer. A seasonal tune-up is a good time to check all of this.
Duct sealing: before & after
Loose, leaky duct connections in the attic let the air you paid to cool escape into the attic, and can pull hot, dusty attic air into the system. On this job we strapped the loose duct back on and sealed the connections with mastic.
If you notice musty odors, extra dust or rooms that feel stuffy, call or text us. If the problem turns out to be the equipment itself, we can handle the AC repair or heating repair too.
