How can I keep my HVAC system effecient?

Keep Filters Clean

Keeping your filters clean can shorten the cycle of your system, therefore saving you money.  In a normal condition changing your filter once a month is sufficient.

Choose the Right Filter

Choosing the right filter can also affect how efficient your system operates.  In temperatures  above 95 degrees you need to make sure you have a filter that is not too restricted.  The reason is in these extreme temperatures your evaporator coil (inside coil) needs to move a lot of air across it to keep up with the heat and humidity entering your home.   A filter that is too restricted will cause your system to run longer than it needs to or in some cases may even freeze up your system.  We normally recommend buying the cheap filters and changing them more often.  There are also many good allergy filters on the market.  What to watch for is the thickness of these type filters.  Normally if you can hold the filter up to a bright light and can barely see through it, it will probably cause too much restriction on your system.

Clean Condenser Coils

Clean condenser coils (outside coil) also makes your system run so much more efficient.  This is where the heat inside your house is released.  If the condenser coil is dirty much of the heat will be cycled back into your home and will also cause your compressor to run much harder and sometimes causing the valves in your compressor to go bad.  Cleaning your coils can be done with a normal spray nozzle.  (Too much pressure can cause damage to your coils).

Programmable Thermostat

Using a programmable thermostat can save you hundreds of dollars over a period of a year.  Raising the temperature during the summer and lowering the temperature during the winter of your house by 2 degrees when your not there can make a big difference in your utility bill.  (TXU says one degree raised or lowered  can save you up to $50 a month).
