Air Conditioning Maintenance
Air Conditioning and Heating Maintenance: Your air conditioning and heating system needs routine maintenance to keep it running its best. Just like your car, without regular servicing, heating and cooling systems waste energy and are more likely to break down.With annual maintenance, you can prevent costly repairs and experience worry-free comfort for years to come.
As much as half of your energy used in your home goes to heating and cooling. Making smart decisions regarding your heating, ventilating, and air conditioning (HVAC) system can have a large effect on your utility bills. Therefore, the first reason for maintaining your heating and cooling system is to make sure it is performing efficiently, which will directly impact your monthly utility bills.
Your heating and cooling system also needs regular tune-ups just like your car. When we turn on our central heat and air units we want them to be able to deliver exactly the temperature we want and to deliver it all day long. If the HVAC unit is not running properly it may be working too hard and we will not experience the comfort of a consistent air temperature that we should be.
One reason many avoid routine maintenance to their HVAC system is the expected high cost of doing so. Due to this fear, many homeowners wait until their home air conditioner won't cool or their furnace won't ignite before they call their HVAC service company. At this point not only do you have to typically pay more for repair or replacement than you would have for regular maintenance but may find yourself waiting around on the hottest or coolest day of the year when their service company is backed up with so many other calls. Having your HVAC system put on a yearly schedule of having the A/C serviced in the spring and the heater tested in the fall saves money and time. Regular maintenance will pay for itself in lower repair costs and more efficient operation.
Routine, scheduled heater maintenance not only allows for a more efficient and trouble-free operation, but it is also a matter of safety. A typical maintenance check-up will include tightening all electrical connections and measuring the voltage and current on motors. Faulty electrical connections can cause unsafe operation of your system and reduce the life of major components.
Most manufacturer's require routine maintenance in order to validate the warranty. Routine maintenance will protect you from major system repairs and maintain your manufacturer's warranty.
It is important to have your heating and cooling system serviced at least one a year, optimally twice is best. Part of this inspection involves lubricating all moving parts. Parts that lack lubrication cause resistance in motors and increase the amount of electricity you use. This resistance can also cause equipment to wear out more quickly, requiring more frequent repairs or replacements.
When it is properly maintained, you can add several years (3-5 years in some cases) to the life of your heating and air conditioning system. Not only will you increase the efficiency during it's lifetime but you actually add years of efficient use.
Another part of air conditioning maintenance is inspecting the blower components, cleaning and adjusting them. Doing so helps to insure proper airflow for greater comfort levels. Airflow problems can reduce your system's efficiency by up to 15 percent.
You, as the homeowner or tenant should inspect, clean or change air filters once a month in your central air conditioner, furnace, or heat pump. A dirty filter can increase energy costs and damage your equipment, eventually leading to early failure.
