You don’t have to be an expert to know that all electromechanical equipment requires periodic maintenance if it is to operate optimally and as per manufacturer’s specification—your heating and AC system included. Even better, I believe you are probably aware that with the nature of precision and safety standards required in these systems maintenance, this undertaking is best left to the professionals.

With all the moving parts, dangerous refrigerants, and the flow of high electric energy, HVACs are very complicated units that need a professional touch. DIYs do not only risk to void your warranty but also endangers your life and those of your loved ones.

Therefore, at least once a year, you should schedule annual maintenance for your heating and AC system in Fort Worth, TX. You don’t want a breakdown during one of the hot summer days in Texas—it is the worst experience you can ever be subjected to.

Periodic maintenance helps to point out potential issues waiting to arise and replacement of worn-out parts that can lead to future problems.

So, what do professionals pay attention to during the annual maintenance of your heating and AC system?


When you want to keep cool in the hot summer or keep warm and cozy in the freezing winter of Fort Worth, TX, you may think that a larger heating and AC system is all you need. That’s not right. While we don’t blame you for having such thoughts, we will make some clarifications.

HVAC always works best when the right size is installed and not any size for that matter. But why? Your heating and cooling needs are specific and so are your HVAC sizing specifications. Ignoring this fact can lead to further trouble and loss of money in replacement.

That’s why during any annual maintenance for your heating and AC system, technicians always consider the size of your unit. They calculate your home’s cooling and heating load and match it to the most convenient HVAC sizing. You don’t have to waste money on a large HVAC system when you can install an average one and still achieve the same levels of comfort and efficiency.


Did you know that the refrigerant is the blood of your heating and AC system? And just like in human bodies, they must be present to a preset level for the HVAC to run as per the manufacturer’s specifications.

Refrigerant is carried in your HVAC by copper coils and it absorbs indoor heat and dissipates it outdoors. In accordance with Texas laws, some of the refrigerants such as Chlorofluorocarbons (CFCs), and Hydrochlorofluorocarbons (HCFCs) have been phased out because they have a negative impact on the environment—they damage the Ozone layer.

The most common refrigerant used nowadays is the Hydrofluorocarbons (HFCs), including R410A and R134, because they are believed to be relatively safer to the environment. There can be no air conditioning without a refrigerant.

That’s why this is another area that HVAC technician in Fort Worth, TX, pays much attention to. They make sure that the refrigerant level meets the pre-set manufacturer’s levels. Without that, there would be a significant issue in cooling efficiency and energy consumption.


Ducts are used as a conduit in a heating and AC system to deliver and remove air. Without these crucial components, it would be impossible for conditioned and filtered air to reach the living spaces and the furnace. Some of the benefits of having clean ductwork system includes:

  • Improving Indoor Air Quality
  • Reducing pollution and promotion of better health
  • Controlling and maintaining comfortable indoor temperatures
  • Reducing HVAC running costs
  • Reduces repair costs

Therefore, during the annual maintenance of the HVAC, technicians evaluate the general status and performance of the ductwork system. They make sure they clean them and remove any debris or other dirt clogging them. More importantly, they check and fix leaks in the system as it leads to low performance and more energy consumption. Always remember insulation of the ducts is very important and during periodic maintenance, this is another area of concern.

Air Flow

Airflow is a basic requirement in your HVAC system. With frequent airflow problems, this area can really affect your heating and AC needs and cause a spike in your energy bill. Weak or zero airflows can cause a sharp rise in your energy bills because consumption is above the average. Cold and warm spots in the house are one of the common pointers to this problem. Some of the causes of airflow problems include:

  • Dirty or clogged air filters
  • Obstructed condenser unit
  • Thermostat failures
  • Low refrigerants levels
  • Dirty condenser coils
  • Mechanical wear and tear
  • Slow HVAC fans
  • Blocked vents

The good news is that these problems can be rectified easily during periodic maintenance. HVAC professionals take airflow in your HVAC very seriously and they use special equipment in Fort Worth, TX, to measure it during regular maintenance and fix any problem and rectify potential issues that might point to failure. Methods they use to prevent airflow problems include:

  • Cleaning or replacing air filters
  • Inspecting and adjusting motors
  • Cleaning coils
  • Inspecting HVAC design and recommending modifications
  • Cleaning HVAC fan blades

After maintenance, we guarantee you a proper distribution of quality and conditioned air throughout your living spaces.

HVAC Coils

In heating and AC systems there are generally two types of coils: the condenser and evaporator coils. The latter is located indoors while the former is located outside. They are basically from the HVAC’s heat pump.

In the evaporator coil, heat is removed from the refrigerant. On the other hand, in condenser coils, two activities occur in the compressor and they involve heating and pressurizing the refrigerant and then forcing it into the condenser where it turns to liquid. Always remember the compressor coil and the condenser coil is the same thing and the names can be used interchangeably.

In the condenser, the refrigerant usually transfers its heat to the air being blown by the HVAC blower fan and cools down. The hot air around the fan is blown outside and the cycle continues.

Now that these two components are very important in HVAC systems, then in periodic maintenance heating and AC technicians pay keen attention to this area by cleaning them. Also during servicing, they repair or replace them if need be.

Clean HVAC coils improve HVAC performance and help on saving on energy bills. It is a proven fact that dirty coils make your HVAC run longer and work harder. According to the US Environmental Protection Agency, dirty HVAC coils increase energy consumption by up to 30 percent.

They recommend that they be cleaned at least once per year and any HVAC technician knows that. But how do they clean these crucial components? The two methods of cleaning HVAC coils include:

  • Use of Chemical Cleaners

It involves the use of two-way foaming chemicals to clean the coils. This method has been deemed problematic as eventually the chemical cleaners may leak into buildings water systems and compromise it.

To prove that these chemicals are dangerous, they come with warning labels that spell the toxicity of their contents. More importantly, these chemicals compromise the integrity of HVAC coils. They are known to erode the copper and aluminum lining. This leads to frequent replacement of parts.

Some believe that it is not an effective cleaning method as it pushes dirt deep into the coils. The only relief is that when an HVAC technician uses this method they are cheap. But cheap is expensive and you might spend more in the long-run.

  • Steam Cleaning

This is a better method of cleaning HVAC coils—involves a green steam clean process. A technician uses highly heated steam at 350°F at 350 psi—it is also called the deep clean. Even though this method is more expensive than the latter, it has been proven that it is a more effective cleaning method. Your coils’ integrity remains intact and it does not have negative health effects.

Importance of Annual HVAC Maintenance

Staying comfortable and breathing quality air in your home comes at an extra cost—but it is absolutely worth it. According to the US Department of Energy, the HVAC unit contributes up to 30 percent of domestic energy bills.

This scenario gets even worse when you are using old, dirty, or faulty HVACs. That’s why preventive maintenance is an effective way of keeping HVACs running optimally without additional expenses and frequent breakdowns.

If not convinced here are some benefits of undertaking annual heating and AC system maintenance in Fort Worth, TX.

Saves You Money

As we have mentioned, faulty, dirty, and old HVAC systems are energy inefficient. They lead to a spike in your energy bills. For instance, clogged ductwork causes the blower motor to work extra hard to force air into the living spaces. This leads to the consumption of extra energy. Annual maintenance can help you mitigate this problem as experts clean and makes sure HVAC is running optimally and helps you to save money on energy bills.

Also, annual preventive maintenance helps to identify potential future issues and fix them. Worn out parts are replaced and moving parts are lubricated. This helps you to mitigate the problem of frequent breakdowns and costs associated with emergency repairs.
