To run at peak efficiency, heating, ventilation and air conditioning (HVAC) unit must be kept clean. Efficiency saves power which, in turn, saves money.
Watch the 1-minute video above and learn how to replace an air filter. HVAC air filters should be changed at least quarterly, with more frequent replacements in certain homes:
- Homes under construction or in repair
- Newly-built homes with loose dust in the air
- Homes of families with allergies or asthma
- Homes of families with shedding pets
Be aware, however, that not all air filters are created alike.
When it comes to air purification, you often get what you pay for as The Carey Brothers prove in this other 1-minute video. Using “The Salt Test”, we see with our own eyes how 99-cent filters are inferior to $16 ones.
The good news is that quality air filters can be found cheaply online.
