Ideally, an AC unit should last approximately 15 years or more. However, if you neglect it, it can conk out in less than 7 years. According to HVAC experts, there are several ways through which you can unintentionally kill your unit. Don’t be the one to blame when your AC stops working in the middle of summer. Below are some of the ways this happens.
If you want to prolong the life of your AC, the best way is to get an inspection from a highly rated HVAC technician at least once a year. Most of the service calls experts attend to stem from irregularly maintained ACs. If you can, having annual service plans will give you the best deal for your money.
A typical tune-up will cost you anything between $70 and $150 and comprises at least two visits a year; one before winter and the other one before summer. During such visits, the technician will clean the outdoor condenser coils and pick up any debris that has accumulated over time. They will also check the return and supply lines, blower and motor, as well as refrigerant levels.
Failure to Change the Filter in Time
Filters should be changed at least every month or at least once every three months depending on how hard your unit is working. Filters accumulate dirt with time and this can restrict airflow. When this happens, the cooling capacity of your system is compromised and your compressor has to work hard to achieve the same degree of cooling as before. Eventually, this shortens the life of your unit.
Research from Energy Star showed that changing dirty filters can lower the amount of energy consumed by your unit by about 5 to 15%. This saves you money on energy bills and you don’t have to replace your unit every now and then.
Constantly Running Unit
Systems operate on the premise that the harder they work, the more tired they get. This applies to ACs also. Experts in the HVAC field say that closing the blinds during the day is one of the simplest ways you can consider so as to lessen the degree of hard work your unit has to do.
Homeowners who have the habit of changing temperatures constantly can also contribute to the death of their units without knowing. Every time you adjust the temperatures, highs and lows are created and this makes your system work harder to either drop or upscale the temperatures. With time, this leads to wear and tear.
Not Conducting Energy Audits
If you want to know that your home is sufficiently insulated and your AC properly sized, do an energy audit. Air leakages can make your systems work harder than necessary and this wears them out. It is recommended that you do a blower test and act on the recommendations to seal your home and save your AC from the trouble that come with leaky spaces.
An energy audit will also give you the right AC size to install based on the dimensions of your home. Don’t let your AC work hard to cool more space than it is made for.
