Air Conditioning Services in Lavon, TX

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.


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.

Signs You Need Air Conditioner Repair in Lavon, TX

Early warning signs will give you the opportunity to take early action. Sensitive systems like your AC will only deteriorate faster if those signs are ignored. With the help from our experts, you won’t have to worry about system failure during the worst time imaginable. Count on your Lavon HVAC service professionals as soon as you encounter these warning signs:

Warm Air

You likely have a low refrigerant level or a broken air compressor. If not looked at immediately, you could experience a system leak. We have the tools and expertise to quickly diagnose the root cause and offer you fast and cost-effective repairs.

Poor Airflow and Quality

A clogged filter could be the culprit or a malfunctioning compressor. Other possibilities include a ductwork problem caused by a potential leak. We recommend seeking help from a Lavon HVAC service professional immediately before these issues deteriorate and cause damage to the fan motor.

Temperature Fluctuations

If your thermostat is playing up, it’s time to replace it. Faulty thermostats can cause lots of confusion and problems even if your AC is in working order. You could try to reset it first, but if problems persist, a replacement is your best bet.

Indoor Humidity

Although your AC is not designed to remove condensation, it can eliminate mugginess by cooling and dehumidifying the air when working effectively. However, you should not ignore excess humidity, as it could lead to additional issues in case your unit is responsible for it. Instead, shut off your cooling unit and check the condensate drain for standing water, clogs or any issues that may need service from a Lavon HVAC service professional. Purchasing a dehumidifier during muggy season will also back your AC’s performance.

Heating Service in Lavon, TX

Although winter in Texas is short, it doesn’t mean that properties will get by without a furnace. In fact, you can’t be prepared enough for a cold, windy winter in Lavon because the polar vortex will continue to strike the state without warning.

After a long hot summer, Lavon residents might not instantly think of inspecting their furnace and hire air duct cleaning service to prepare for the winter. Whether you have a furnace or a heat pump, our skilled Lavon HVAC service professionals are one call away from helping you ensure they’re ready for the cold season.

Heater and Furnace Services

You may be taking your HVAC system for granted and forget about the routine maintenance required to keep it in shape. Simple furnace tune-ups can help you avoid a number of problems in the future. Living in a climate that’s either too hot or too cold can be very stressful, especially if you heavily rely on your HVAC to find the middle spot that keeps you safe and comfortable.

Air Duct Cleaning and Vent Cleaning

Air ducts are known as our HVAC ductwork system that connects to our furnace. Air enters through our air vents to the furnace with the help of the air duct network. When air has been heated, our air ducts are responsible for filtering and circulating heated air through your Lavon home in the winter.

The vent covers or registers may hide the proper view, but it’s a vast metallic system that connects to all rooms in the house. (If you are equipped with an AC, you will also have AC ducts.) These vents, when not in use, collect dust, pollen and other debris over the summer, which is why we typically receive requests for air duct cleaning towards the end of summer or early fall. This way, when you turn on your furnace, you won’t have to worry about debris and other contaminants being blown into your home.


Heating systems like your furnace that pulls in air to convert them into heated air, deal with lots of debris that catches in the filter. It’s not only to protect your home from contaminants and allergens, but also to protect the blower fan from getting clogged. Filter changes are typically the number one rule in HVAC. Lavon, TX homeowners are recommended to switch out the furnace filter at least once a month during peak use in the winter.

Signs You Need Furnace Repair in Lavon, TX

Furnace issues happen, but you certainly don’t want them to occur on the coldest day of the year. Signs of duct leak or cycling are issues that need emergency repairs but your Lavon HVAC service professional can help you prevent these issues by taking preventative measures beforehand. There are many signs that you need help with your HVAC. Lavon, TX service pros can eliminate these signs before they occur during a cold spell:

  • Failing thermostat: Does your furnace shut off for no reason or show inaccurate temperature readings? Try to reset it to see if it fixes the issue, if not, a replacement will do the job. Also, for proper heat distribution, ensure that the setting is at AUTO, not ON. This way, the blower will run only when required.
  • Low airflow: You likely have a clogged filter that needs replacement. An additional tip is to make sure the blower motor fan is not dirty and your vents aren’t blocked.
  • Flame sensor corroded: If your pilot light is off, check if the sensor is corroded because carbon buildup is common over time. If the system doesn’t detect the flame, it will automatically shut off for safety reasons.
