Regular replacement of the filter for your heating, venting and air conditioning unit helps your system operate at peak levels and improves indoor air quality.
The filter of the unit, especially if it's an HVAC unit that will tend to get nearly year-round use, should be changed by the homeowner at least every three months, but possibly more often.
As your HVAC system runs, it accumulates dust and dirt in key areas that affect its efficiency, like the condensing coils and air filters. Left unchecked, your A/C system can lose 5 percent of its operating efficiency each year because of this buildup, meaning it can’t cool your house as capably as it could if it were clean.
Use these guidelines to find the appropriate BTU/hour rating. You need approximately 6,000 BTUs to cool an area under 300 square feet, 10,000 BTUs for 301 to 549 sqft., 16,000 BTUs for 550 to 999 sqft., 22,000 BTUs for 1,000 to 1,199 sqft., 30,000 BTUs for 1,500 to 1,999 sqft. and 34,000 BTUs for 2000 to 2,499 square feet.
Regular preventative maintenance is the best way to ensure trouble-free operation and peak performance of your home comfort system! Pre-season maintenance can help you avoid a system failure especially in extreme heat or cold. Preventative maintenance is required by manufacturers and allows you to maintain a factory warranty on your system.
