HVAC Maintenance

HVAC maintenance plays a crucial role in ensuring the efficient operation and longevity of your heating, ventilation, and air conditioning (HVAC) system. By regularly servicing your HVAC system, you can enhance indoor comfort, improve energy efficiency, and minimize the risk of costly breakdowns. Here is a comprehensive overview of HVAC maintenance:

HVAC Maintenance Checklist

  • Find screw issues, recharge P-traps or U-bend water traps.

  • Hire a professional to inspect chillers and boilers.

  • Inspect cooling towers for fill, fill valves, fan blades, motor bearings, gearbox and support structure, wiring and log observations.

  • Check and lubricate pumps once a year.

  • Clean and replace air filters once a month or twice a year, depending on the type

  • Inspect and clean the condenser coil, if required

  • Check energy efficiency settings, including the compressor and the refrigerant

  • Confirm that the superheat temperature is between 10 and 20 degrees Fahrenheit.

  • Clean the economizer for corrosion and debris, and calibrate sensors.

  • Check and make necessary adjustments to the thermostat.

  • Check the wear and tension of the blower belt and make any necessary adjustments.

  • Check the voltage and amperage drain on all motors with a meter.

  • Check the compressor contactor.

  • Check the amp draw and visually inspect the compressor.

  • Check the potential relay and the start capacitor.

  • Check the cut-out setting on the pressure switch.

  • Clean and maintain ductwork to prevent blockages and improve efficiency

  • Check refrigerant levels and connections on air conditioning units

  • Install programmable thermostats to save on energy costs


What is HVAC maintenance?

HVAC maintenance involves the regular care, inspections, and repairs performed on HVAC systems to keep them operating effectively.

Why is HVAC maintenance important?

HVAC maintenance is important for several reasons:

  • It ensures optimal system performance and efficiency.

  • It helps prevent costly breakdowns and repairs.

  • It improves indoor air quality and comfort.

  • It extends the lifespan of the HVAC system.

How often should HVAC systems be serviced?

The frequency of HVAC servicing depends on factors such as the type of system and usage. Generally, annual maintenance is recommended for residential systems, while commercial systems may require more frequent servicing.

What tasks are included in HVAC preventative maintenance?

HVAC preventative maintenance typically includes tasks such as inspecting and cleaning system components, lubricating moving parts, and testing and calibrating controls.

Can I perform HVAC maintenance myself?

While some maintenance tasks can be handled by homeowners, comprehensive maintenance is best left to qualified HVAC technicians to ensure proper system functioning.

How much does HVAC maintenance cost?

The cost of HVAC maintenance varies depending on factors such as the size of the system and the level of service required. It is generally more cost-effective to invest in routine maintenance to prevent major repairs or replacements.

What is included in an HVAC maintenance checklist?

An HVAC maintenance checklist may include tasks such as checking and cleaning coils, inspecting ductwork, lubricating moving parts, and verifying electrical connections.

Should I sign an HVAC maintenance agreement?

Signing an HVAC maintenance agreement can provide benefits such as regularly scheduled maintenance visits, priority service, and potential discounts on repairs and services.

What are the advantages of commercial HVAC maintenance?

Commercial HVAC maintenance ensures a comfortable and healthy indoor environment, maximizes energy efficiency, and minimizes system downtime and business disruptions.

How can HVAC maintenance help extend the lifespan of the system?

Regular maintenance helps identify and address minor issues before they become major problems, reducing strain on the system and prolonging its lifespan.
