Having a reliable air conditioner is far more than just a luxury in certain places. Sweltering temperatures in Texas marks the state as ground zero for heat strokes. With an average of 134 of heat-related deaths every year, you want to ensure your air conditioning unit is in top-notch condition to help keep you cool throughout the summer season. Problems with AC systems are more common due to many reasons that range from moisture to technical issues. In short, it requires frequent maintenance to stay in shape. Your Lavon HVAC service professional has a checklist of preventative maintenance services to help you with that. To better understand an AC’s functions, it’s important to know the different parts the system is made of and how they could potentially call for repair or replacement.
Filter
You know the nuisance of clogged filters when suddenly airflow is reduced, the system starts to overwork and your monthly energy bill goes up. If the clog goes unnoticed, it could lead to a system failure that includes a broken motor. Most AC filters are either reusable or need replacement after a certain time. Frequent cleaning or replacement is extremely crucial during peak use periods, when inside your home could be subjected to higher levels of dust and pollen despite closed windows and doors. Your Lavon HVAC service professional recommends a replacement filter once every month or two during peak season. You can clean reusable filters as often as you’d like. Keeping your filters clean will help increase your AC system’s efficiency and performance.
Evaporator Coil and Condenser Coil
The evaporator coil is located near the air handler by the blowing fan. It’s part of the system where the refrigerant absorbs the heat from your house. It also collects dirt during use. These coils are primarily made of metal material like copper, steel or aluminum because they handle heat more efficiently. Evaporators have metal fins that are put together as panels to form an A-shaped roof. Over time, they collect dirt, unless you take good care of your filter. Otherwise, when accumulating dirt, you will get a reduced airflow that compromises the evaporator coil’s ability to absorb heat.
Your condenser is the large, square unit you have outside. It’s a crucial part of the overall system as it contains other elements including compressor, fan, tubings and fins. As an exterior unit, it’s prone to getting dirty, particularly if there are dryer vents and dense bushes nearby. Ensuring your condenser coil isn't blocked and receives adequate airflow is important. During a thorough inspection, your Lavon HVAC service professional will check your coil fins to make sure they aren’t bent or obstructing airflow. We recommend scheduling an appointment to help with HVAC. Lavon, TX homeowners should have their coils cleaned at least once a year before peak season starts.
Expansion Valve
When the compressor pulls cool, liquid refrigerant through the evaporator coil, it first passes through an expansion valve which is designed to reduce pressure from the refrigerant. While passing the expansion valve, the cold liquid refrigerant, it absorbs the hot air from your home. This valve controls how much refrigerant enters the evaporator coil.
Condensation Drain
While your coils remove humidity from the air, the humidity converts into liquid and flows into a pan before going down the drain line. If condensate drains are ever clogged, the water will trigger excess moisture in your home that could impact your walls and floors. Your Lavon HVAC service professional recommends you check your condensate drain for standing water during maintenance and clean the drain when necessary.
Attic Fan
You may wonder how your attic fan is connected to your AC’s functions. A healthy attic insulation combined with a reliable attic fan will ensure energy efficiency and help circulate fresh air throughout your home as well as back your AC. It’s the kind of team work that will save you money. If you’re unsure about your attic fan’s condition, contact your experts in HVAC. Lavon, TX can trust the pros at Aire Serv of Rockwall.
Pro Tip:
During winterization in Lavon, we recommend that you give your AC system a good clean before you turn off the system at the end of peak season. Covering up the exterior unit will prevent debris accumulation.
