Three Things To Know About Professional Maintenance Of Your Air Conditioning Unit

Just like many other mechanical or electrical devices, your air conditioning unit needs to be maintained. This type of work goes beyond what most homeowners are capable of doing. The following are a few things you should understand about professional maintenance of your AC unit.

Maintenance involves inspection and cleaning

Professional AC technicians not only know what to inspect, but they also know what they are looking at. A trained eye will know whether there is a problem with the appearance of the unit's components. Electrical contacts, for example, should be free of corrosion. If necessary, cleaning can be done and testing performed to make sure the wiring is operating properly. A general cleaning is often necessary because dust and dirt can hasten the failure of both electrical and mechanical components. Moving parts in your AC system may not only require cleaning but lubrication as well. A technician will know which parts need lubrication for your particular model. Coolant levels can be checked and replenished as needed.

Maintenance involves part replacement

Certain parts can be tested to see if they are performing adequately. One example is the thermostat. If a thermostat is operating in a sub par manner, it can be replaced. Other parts can be checked for extreme wear and replaced before they break. An inspection of the motor can reveal issues that can become problems later such as overheating. Other key components will have a greater likelihood of failure depend upon the age of your unit. They can often be replaced before the time they typically will fail.

You can buy a maintenance agreement

Not only should you have your AC unit serviced once a year, but there a many HVAC contractors who offer service agreements. By purchasing a service contract, you will not be forced into remembering to call for maintenance. They will remind you when the time comes. In addition, if your unit requires repairs during the year, an HVAC service company will likely give you priority attention as you are already a customer. This can be beneficial if your air conditioner were to break down during the peak usage of summer. A time when HVAC companies can be overwhelmed with demand for their service.

If you haven't been doing annual maintenance on your HVAC system, you need to make an appointment to have a professional technician perform a tune up as soon as possible. In addition, you should give consideration to purchasing a maintenance contract for the reasons explained above. For more information, contact companies like Miller Services HVAC Inc.
