    HVAC systems play a vital role in maintaining the temperature of a commercial or residential space. However, most people don’t realize that these systems need regular maintenance in order to function properly. Neglecting to properly care for your HVAC system can lead to decreased efficiency and even complete system failure. Taking some preventive measures now can save you time and money in the future.
    This guide will help you understand the importance of HVAC preventive maintenance, and provide you with some tips and tricks to keep your system running smoothly.

    HVAC Systems and HVAC Preventive Maintenance

    HVAC — “Heating, Ventilation, Air Conditioning” — is a functional combination of various technologies to ensure a desirable temperature in an enclosed expanse. It is a reliable and efficient service that controls the air quality, humidity, and purity. Consequently, the occupants enjoy thermal comfort in a commercial or residential space.
    HVAC systems are delicate and, as such, require preventive maintenance in order to function at maximum efficiency. By carrying out regular maintenance tasks, any issues with the system can be identified and rectified before they cause significant problems.
    Hence, the chances of a system catastrophe are greatly reduced.

    3 Major HVAC Preventive Maintenance Categories

     The HVAC system must be regularly serviced to ensure optimal performance and prevent unexpected failures. This system is carefully distributed into three main categories. These categories translate into three critical steps and help formulate a preventative maintenance plan. Enlisted below are the categories that technicians and equipment owners must consider while performing HVAC preventive maintenance:

    General Service Checks:

    General service checks are mandatory and must inspect ductwork, electrical lines, and other facility infrastructure.

    The Heating Equipment:

    Heating equipment, such as furnaces, boilers, heat exchangers, and blower motors, must be regularly inspected and serviced. These systems are typically energized with gas, electricity, and oil, so it is critical to check for issues and replace parts as needed.

    The Cooling System:

    Cooling equipment, such as roof-top units (RTUs), must also be regularly serviced. RTUs contain coils that are comprised of refrigerant, and these need to be checked for proper operation.

    Why Should You Perform HVAC Preventive Maintenance

    The importance of HVAC maintenance should not be overlooked as it is crucial in ensuring your system remains up and running smoothly. Below are 7 tangible benefits that make preventive maintenance an absolute necessity for your HVAC system:

    Bid Farewell to Costly Breakdowns:

    By regularly servicing your HVAC system, you can identify potential problems before they lead to costly breakdowns. This helps to reduce the risk of system failure, and as a result, lowers your repair bills.

    Enjoy Improved Air Quality:

    One of the key functions of an HVAC system is to filter the air and provide improved indoor air quality. If you don’t clean the mold and dust accumulation on (and in) your equipment, you will never be able to enjoy that fresh breeze. Furthermore, if you or your family members suffer from air allergies (pollen allergy), asthma, etc., it is even more important to take preventive measures.
    Takeaway: Always take preventive measures and keep your HVAC units tidy and clean.

    Turn Down The Environmental Footprint

    HVAC equipment consumes energizers which can be harmful to the environment. For instance, ACs use refrigerants and electricity that negatively impact the ozone layer. By ensuring your HVAC units are regularly serviced by a professional, you can reduce their energy consumption and do your part in protecting the environment.

    Extend the Life Span of your Heating and Cooling system

    With proper maintenance, your HVAC system can last up to 30 years. However, if you neglect your system, it is likely that it will not survive until its average life expectancy, and you will end up having to replace it within 20 years.

    Reduce Your Energy Bills

    If not maintained properly, your HVAC system will use more heat, energy, and resources. This increase in energy consumption not only hurts the environment, but also sums up to higher energy bills. A study shows that most families in the US spend as much as $2,000 yearly on energy bills, with half of that going towards keeping the house cool or warm. The best advice is to act wisely and plan scheduled HVAC maintenance in order to avoid those hefty energy bills.

    Protect Yourself, Your Family, & Your Workplace

    A neglected HVAC unit only elevates the potential risks of a catastrophe. Think of a short circuit, a gas leak, or a fire breaking out in your home or office. No one would want to endanger human lives leaving these potential risks unresolved. A preventative maintenance plan helps you subside these dangers and guarantee greater protection. 

    Keep Your HVAC System Under Warranty:

    HVAC systems typically come with a certain warranty. However, this warranty is only claimable if the HVAC system is regularly serviced. If you don’t service your system at the ideal interval, your warranty claim won’t hold any weight

    Your Masterplan For Optimal HVAC Preventive Maintenance

    HVAC tune-up involves carefully examining and maintaining all the moving parts, including the refrigerant charge, condenser, evaporator coils, condensate drain, etc.

    This is typically done by a contractor as part of a preventative maintenance contract. However, you can use this checklist to make sure that the contractor is efficiently carrying out the maintenance process.

    Pro Tip: Take advantage of the NonStop Group’s electronic forms to automate your maintenance checklists and efficiently supervise the maintenance process.

    Residential HVAC Preventative Maintenance Checklist

    Most people are not well-educated about the HVAC maintenance of their homes. If you are on your way to inspect your residential HVAC preventive maintenance, keep the following checklist at hand.

    Air Conditioner (AC) Maintenance Checklist for Spring & Summer:

    ⦁ Check that the fan motor is functional.
