Like other appliances, your central air conditioner needs regular maintenance to keep operating at peak efficiency. However, many homeowners aren't aware of the maintenance services that professional HVAC technicians can provide. Here is an overview of three essential types of air conditioner service.
A tune-up is a general term for an AC maintenance call, and it covers all of the basic tasks that your technician will perform. During a tune-up, technicians will check the calibration of the thermostat, make sure all electrical connections are secure, evaluate the blower performance, check for duct leaks, and perform a number of other small, performance-increasing tasks.
AC efficiency loss is often a result of failing or underperforming minor components within the system. During a tune-up, many technicians will replace or upgrade these components for you, often at no additional cost if the part is under warranty.
2. Coil Cleaning
Your central air conditioner uses evaporator coils inside and condenser coils outside to transfer heat from the interior of your home to the outdoors. Over time, these coils can become covered in dust and dirt that inhibits their ability to transfer heat. When this happens, your home won't cool properly and you may see an increase in your monthly energy bill.
Professional HVAC service almost always includes cleaning both the condenser and evaporator coils. Technicians use professional-quality chemical cleaners that can remove more dust and dirt than homeowners could with DIY methods. After a coil cleaning, you can expect better in-home comfort and improved airflow from your vent registers.
3. Refrigerant Recharge
The condenser causes the refrigerant in your system to expand to release heat outdoors. When your system is low on refrigerant, it will still attempt to expand the same amount. This can cause your refrigerant lines and coils to fall below freezing temperature and your air conditioner may ice over.
Refrigerant isn't used up over time, so a low refrigerant level must mean there is a leak. Additionally, only licensed technicians are permitted by the EPA to handle AC refrigerant due to its environmental effects. On a maintenance call, your technician will check refrigerant levels, recharge the system if necessary, and identify the source of the leak.
Professional air conditioner service is much more than simple cleaning. If you are unsatisfied with your air conditioner's cooling performance, contact local companies like Soco Air Conditioning. Ask about maintenance options so you can avoid unnecessary breakdowns and greatly extend the lifespan of your air conditioner.
