Causes of Mid-Summer AC Failures

After harsh winters and milder springs, everyone looks forward to the summer season. The finer weather, barbecues in backyards, and holidays are just some of the reasons why families tend to be excited when summer nears. While all this looks exciting, there is one aspect that is oftentimes pushed to a back seat, but which may cause frustrations to homeowners: HVAC performance and repairs.

As temperatures start to soar in the mid of summer, no-cool calls tend to increase in number. the genesis of many of these calls is systems that were not inspected at the onset or even before the summer season. To help you out so that you do not become a victim this summer, below are some of the top issues you need to address before the heat gets the best of you.

Dirty Air Filters

These can wreak havoc on your AC unit and significantly undermine its performance. Experts recommend that your standard one-inch filter should be replaced at least once every 4 weeks. Ensuring your filter is cleaned and maintained is much more important because a dirty one can potentially shorten the lifespan of your AC unit.

When the filter becomes dirty, it restricts airflow. This means its capability of providing sufficient airflow in and out of your system is greatly hampered and your unit will be forced to work extra hard to cool your home to the desired level. Filters are generally cheaper, but if you do not take good care of them, they can expose your system to massive repairs.

Dirty Condenser Coils

Your AC system has two coil systems: the evaporator coil and the condenser coil. The evaporator coil is usually located on the inside while the condenser coil is the part of the AC that is found outside your home. The job of the evaporator coil is to draw heat from your home while the condenser coil disperses the heat into the outside environment.

When the condenser coil gets dirty, the efficiency of the AC unit goes down significantly. You will start noticing your hydro bills going up and your unit working extra hard which by extension decreases its lifespan. Also, there is a running risk of total failure of your unit if this problem is not addressed.

It can be tempting to pick a garden hose, some cleaning chemical, and a brush to clean the coils yourself. It is highly advisable that you don’t do this because you risk voiding your manufacturer’s warranty and you may even be electrocuted or damage the unit. The best approach is to contact a qualified HVAC technician to assess your unit and do the maintenance task.

Risk of Electrical Storms

The summer season is associated with electrical storms. This is why homeowners are advised to shut their AC units immediately they hear wind of an electrical storm passing through. Such storms cause fluctuations in electrical currents and this may blow contactors and damage capacitors and thermostats.

To avoid the above problems, homeowners are encouraged to do a spring checkup and service. Regular and scheduled maintenance is imperative and it can help you avoid common problems associated with ACs during summer.
