Inspect and Clean Coils


Dirty HVAC coils can make your system work harder and use more energy. Inspecting and cleaning evaporator and condenser coils helps keep your system running efficiently. Evaporator coils are the lifeblood of home cooling, and when they are clean, your AC unit produces treated air more effectively.


Check Thermostat Settings


Make sure your thermostat is set to the correct temperature and functioning correctly. Upgrading to a programmable thermostat can provide more granular control over your environment and deliver energy savings.


Clear Debris Around Outdoor Units


Lawn clippings, dirt, and other debris can accumulate around your outdoor unit, restricting airflow. Keep the area around your outdoor units clear for best performance. Completing this maintenance task removes any potential obstructions that could cause your air conditioning unit to operate less efficiently.


Inspect Ductwork As Part Of Your HVAC Maintenance Checklist


Inadequate ductwork can waste a lot of energy. Inspect your ducts for any visible leaks. If you find any, seal them with duct tape or mastic sealant. Properly sealed ducts ensure that treated air reaches every part of your home without losing heat or coolness.


Test Safety Controls


Your HVAC system has various safety controls to protect your home. Test these controls regularly to ensure they are working correctly. For example, gas furnaces have safety switches that prevent the furnace from operating if there's a problem, which helps prevent dangerous situations.


Lubricate Moving Parts


Lubrication reduces friction in your system's moving parts, which can prevent wear and tear. Check and lubricate these parts as needed. This step is essential for components like the heat exchanger, which needs to function smoothly to transfer heat efficiently.


Check The Level Of Your Refrigerant


Your AC system must work harder to cool your home when the refrigerant level runs low. To make matters worse, it increases energy costs, too!


The refrigerant in your air conditioning systems is crucial for absorbing heat and cooling the air, so it won't work as expected if it's low.


Schedule Professional Inspections


Professional HVAC inspections are essential to keep your home running optimally. A licensed HVAC technician can identify and fix issues you might miss, reassuring you that your HVAC equipment is in top condition and your home is comfortable.


Keep Registers and Vents Open


Ensure that all registers and vents are open and unblocked. Closed vents can strain your system and reduce efficiency. This step is vital for heat pumps and mini-split systems because they need an unobstructed airflow to heat or cool your home efficiently.


Why Regular Maintenance is Crucial


Following this checklist can help prevent unexpected breakdowns and costly repairs. Regular HVAC care and maintenance can extend the lifespan of your HVAC units, ensuring that your home remains comfortable throughout the year.


Understanding Your HVAC System


Your HVAC system comprises several components, each crucial in maintaining a comfortable indoor environment.


The exact configuration of HVAC systems can vary. Generally, this system includes a furnace for heating and an air conditioning unit for cooling. Ensuring that both meet energy efficiency ratings and are well-maintained helps you stay comfortable regardless of season. Let's talk about some of the different components: 


Air Conditioner


The air conditioner is the part of your HVAC system that is responsible for cooling your home. This component extracts heat from the inside air and releases it outside. Keeping your air conditioner in top condition ensures you always have cool air during the hot months.


Gas Furnace


The gas furnace heats the air and then circulates throughout your home. Regular maintenance ensures it operates efficiently and safely, providing warm air during cold months.


Heat Exchanger


The job of heat exchangers is to transfer heat from the combustion process into the air that circulates and distributes through ductwork. Regular inspections and maintenance ensure that it operates efficiently and safely.


Evaporator Coil


The job of your evaporator coil is absorbing heat from the air inside your home. It's a critical component that produces cool air. Keeping the evaporator coil clean is essential for efficient cooling.


Heat Pump System


A heat pump system heats and cools by transferring heat between the indoors and outdoors. Regular maintenance ensures that home heat pump system operates efficiently in both modes.


Mini Split Systems


Mini split systems are versatile HVAC units that provide treated air to specific areas of your home. Ideal for homes without ductwork, they provide zone control. Regular maintenance ensures they operate efficiently and provide the desired comfort.


Benefits of Professional HVAC Maintenance, Repair, And Installation


Professional HVAC installation ensures that your system operates efficiently and effectively. This approach guarantees that all components are correctly set up and integrated for optimal performance.
