Why You Should Have A Heating And Air Conditioning Repair Company Maintain Protective Components Of The HVAC System | Cypress, TX

Do you have an HVAC system installed at your home? Then you must understand how various components of your unit work. Knowing how they operate, you can detect any signs of failure and take the required steps, like calling a heating and air conditioning repair technician for further inspection. Additionally, knowing how the appliance works is critical to its maintenance. Thus, you’ll get to save money and prevent inconvenient downtimes, especially for those who have installed HVAC systems in their offices. However, some heating and air conditioning system components protect it from unforeseen failure. These components act whenever they detect something amiss in your HVAC system, preventing fires, compressor failure, or even high energy use. This article addresses these components and measures you should take to ensure they remain operational.


A contactor is among the lesser-known components of your HVAC system, albeit critical. It controls where and how electricity is delivered to some parts of the HVAC system to cool or heat your home. Hence, it is directly responsible for the efficient functioning of your HVAC system. Its failure could mean that the unit will likely not start. You should have a routine inspection by the heating and air conditioning repair technicians when they come for a maintenance visit.

When it is time to start a cooling or heating cycle, the contactor receives the signals regarding the voltage from your thermostat. When the contactor receives the signal, it is lowered. This allows the electricity to start flowing through. When the thermostat finishes the cooling cycle, the contactor raises and stops the electrical flow into the HVAC system. Unfortunately, there are some times when the contactor might need to be more efficiently functioning.

This mostly happens due to compressor damages that aren’t addressed quickly. Since replacing the contactor is a high-voltage hazard, you should leave the job to a heating and air conditioning repair technician. A properly working contactor protects your system from overcharges. Hence, be proactive and regularly maintain your HVAC system, including the contactors.

Air Filters

When did you last change the air filters in your HVAC system? Can you even recall? Though at times the most overlooked component of the heating and cooling system, the filter is one of the most critical parts of an air conditioning unit. They are not just cardboard boxes filled with pleated or fiber material. They are also protective of your HVAC system. But how do they achieve this?

Well, the primary function of your air filters is filtering air circulating through the heating and air conditioning system. All the air that cools or heats your home must pass through an HVAC air filter. Hence, keeping the filters clean will ensure the HVAC system runs smoothly and efficiently. It also ensures that you have enhanced indoor air quality and that everybody at your home breathes fresh air. Additionally, heating and air conditioning repair technicians recommend replacing the air filters for at least 1-3 months or less for homeowners with pets and toddlers.

If the air filters are dirty, they reduce comfort and airflow at your home. As a result, the fan uses more electrical power to move the air. You will have to pay more in electrical bills, which you could have avoided by ensuring that your filters are clean. Unfortunately, the additional strain on your HVAC system could expose various components to premature wear and tear. Hence, you could call a heating and air conditioning repair technician to replace a component or repair the unit frequently. The filters protect your system from issues like straining, short cycling, and dirty evaporator coils by filtering the air.


The other protective component of your air conditioner is the fuse. It blows whenever there is a malfunction, cutting down the power supply into your HVAC system. Therefore, you should keep replacing the fuse now and then. You will find a fuse in the evaporator coils, compressor, wiring connections, and motors. Fuses protect the components above from overloading and overheating. With each component serving to complement the functionalities of the other, failure in one could mean that your entire HVAC system will be dysfunctional. Are fuses blowing frequently? You should call a heating and air conditioning repair company to have your unit inspected for various issues. It is the fuse that protects these components from breakdown. Keeping a supply of replacement fuses may help, but you should have routine maintenance from your reliable heating and air conditioning repair technician. The professionals will be able to inspect your unit to determine what is causing the fuse blow-out and resolve the issue.


Owing to how much homeowners use their HVAC systems, they should only stop at something to ensure they save money and energy. For this reason, you must understand how intertwined your HVAC system and thermostat are. It can help you choose a quality thermostat. The thermostat is triggered whenever the temperatures become too hot or cold, circulating cold or warm air throughout your home. You can liaise with a heating and air conditioning repair company to install a smart or programmable thermostat for more effective temperature and humidity control.

These thermostats can be programmed or adapted to your routine for more personalized heating or cooling. In doing so, they help reduce heating and cooling energy expenses. Lack of preventative maintenance upkeep could cause the thermostat not to cool or heat your home correctly whenever needed. This will cause your home to become uncomfortable. Failure to have a heating and air conditioning repair technician service your HVAC system and thermostat means you’ll spend a fortune on heating and cooling energy.
