What Should You Know About Your Air Conditioning System
Many homeowners forget about their air conditioning unit until it stops working, but having a good understanding of your system can often provide some indications that a problem exists, giving you time to take care of it before it shuts down. In many instances when the air conditioner quits it is because of a lack of routine maintenance.
There is a lot of science involved in the workings of these whole house units, but simply stated the relationship of the unit’s pressure and temperature is responsible for its ability to function properly. One of the primary things you can do to prevent problems is to keep the filter clean and keep dust and dirt from building up on the evaporator coils, on the top of the furnace unit and on the outside unit of your system.
It is recommended that the air filter be changed at least once a month, sooner if there is a lot of dust in the air or outdoor construction has stirred up a lot of dirt. Clogged filters and dirty coils can restrict the air flow in the system resulting in higher operating temperatures that leads to higher pressure in the system upsetting the balance of the temperature and pressure relationship. If your system is low on refrigerant, your HVAC contractor will be needed to find and repair the leak that caused it, and recharge you system for optimal performance.

An air conditioner (often referred to as AC) is a home appliance, system, or mechanism designed to dehumidify and extract heat from an area. The cooling is done using a simple refrigeration cycle.

Another way to help your air conditioning system is to reduce its work load by using a programmable thermostat. These can be used to adjust the temperature without having to manually turn the unit up or down when you’re not going to be at home. You can set the temperature higher for the time when your home is unoccupied, such as during the day when everyone is at work or at night when everyone is sleeping. It can be programmed to lower the home’s temperature shortly before you return home or wake up to provide comfort when you get there. Reducing the unit’s work load is only one benefit as raising the temperature when you’re not home as you will also save money on your energy bill.
Insulation in the home is often associated with saving money on your heating bill, but those same leaks that allow warm air to escape in the winter can allow cold air to escape in the summer. Ensuring there is enough insulation in your home’s walls and attic, as well as sealing the windows and doors can be instrumental in reducing the wear and tear on your air conditioner as well as cut your energy costs.
Getting to know the company that works on your HVAC system can also ensure the system is maintained properly and will continue to provide comfort for your home. Most companies offer maintenance programs that provide annual check-ups of your system to ensure they are in good working order. Many homeowners choose a twice-a-year agreement during which the company will inspect the air conditioning system at the beginning of the cooling season and the furnace before winter sets in.
