WHAT HAPPENS DURING A PREVENTIVE HVAC MAINTENANCE INSPECTION?

July 20, 2023

Maintenance is an important aspect of owning a heating and cooling system, and it can help you keep your HVAC system working efficiently. Over time, dust, dirt, and grime can wear down HVAC parts, and worn parts can lower the efficiency of your HVAC system and increase the risk of problems.

Scheduling regular preventive maintenance for your furnace and air conditioner can improve the lifetime of these units by up to 48% and prevent yearly losses of up to 15% in heating and cooling efficiency.

HEATING MAINTENANCE

Just before or during the heating season, a heating maintenance check includes an inspection and testing of your furnace or boiler.

During this visit, your HVAC technician will check and replace your furnace filter if necessary. He will inspect your heater’s exterior and ventilation system for signs of wear and perform any necessary repairs.

Next, the interior components of your furnace will be cleaned and inspected for signs of wear or damage. This includes the ignition assembly, blower, motors, and pressure switches. The power consumed by your furnace and its electrical components will be measured to check for unnecessary power usage.

Your home’s thermostat will also be checked, cleaned, and calibrated. The furnace will be turned on and monitored during function to ensure each component is performing properly. Additionally, your HVAC technician will test for carbon monoxide leaks and ensure all ventilation and piping is clean. If you have a boiler, the controls, safeties, pump, low water cutoff, and sight glass will be checked.

COOLING MAINTENANCE

The lifespan of a central HVAC system is about 15-20 years. A maintenance check can help you maintain efficiency, and before or during the cooling season, it consists of a thorough examination of your home’s air conditioner to ensure it is in top condition.

Your technician will check both the indoor and outdoor components of your air conditioner, including all internal parts, motors, and belts. The air conditioner’s coolant levels will be measured, and lost coolant replaced if necessary. Your technician will check the circuits, safety controls, drain line, condensate pump, and all caps and valves as well.

Electrical components will be inspected for signs of wear or damage and replaced to prevent sparking or failure. He will check that your outdoor unit is level for optimum performance. If needed, he will also replace your home’s HVAC filter to prevent dust and debris from entering your air conditioner or ductwork.

Your thermostat will be inspected and cleaned or calibrated if necessary for more efficient cooling.

Why Preventative HVAC Maintenance is Important

Regular HVAC preventative maintenance offers several key benefits:

Prolong System Life: Well-maintained HVAC systems last significantly longer than those with little to no upkeep.
Reduces Long-Term Costs: Improved system efficiency can lower energy bills, saving you money.
Enhances Indoor Air Quality: Clean filters and ducts reduce airborne particles, creating a healthier home environment.
Prevents Unexpected Breakdowns: Regular maintenance minimizes the risk of system failures, ensuring your home stays comfortable year-round.

By keeping up with HVAC preventative maintenance, you’re investing in the longevity, efficiency, and cleanliness of your home’s heating and cooling system.

How Frequently Should HVAC Be Inspected?

HVAC preventative maintenance is recommended at least twice a year—once in the spring and once in the fall. This ensures your system is prepared for the demands of the upcoming season, whether it’s keeping your home cool in the summer or warm in the winter.

Regular inspections also help catch minor issues before they become major problems, saving you from unexpected breakdowns and costly repairs.

What Happens If I Avoid HVAC Maintenance?

Neglecting HVAC preventative maintenance can lead to several issues that affect your comfort and wallet, including:

Increased Energy Bills: A poorly maintained system has to work harder to heat or cool your home, leading to higher energy consumption and increased utility costs.
Potential Equipment Failure: Small issues can escalate to major failures without regular maintenance, often requiring expensive repairs or complete system replacements.
Decreased Comfort Levels: A neglected HVAC system may struggle to maintain consistent temperatures, leading to uneven heating or cooling throughout your home.
Health Problems: Dirty air filters and ducts can circulate dust, allergens, and other pollutants, potentially worsening allergies or respiratory issues.
Unpleasant Odors: Mold, mildew, and other contaminants can build up in a neglected system, leading to musty or unpleasant smells circulating through your home.
Early Replacement Costs: Without regular care, your HVAC system’s lifespan can be significantly shortened, leading to the need for an earlier-than-expected replacement.
Reduced Warranty: Many HVAC manufacturers require regular maintenance as part of their warranty terms. Failing to keep up with maintenance could result in a voided warranty, leaving you to cover repair or replacement costs.
Preparing Your Home for Spring/Summer HVAC Maintenance

Before the warmer months arrive, preparing your home for spring/summer HVAC maintenance is important. Here’s how you can get started:

Check Your AC System: Before your technician arrives, check your AC system for a few minutes. Ensure the thermostat is functioning correctly, and listen for any unusual sounds. If you notice anything out of the ordinary, be sure to mention it to the technician.
Clean Your AC: A clean system runs more efficiently. Clear away any debris from the outdoor unit, ensuring the area is free from plants or other obstructions. You can also clean or replace the air filter to improve airflow and efficiency.
Understand the Lifespan of Your AC: AC lifespans vary based on factors like the model and how well they are maintained. Regular HVAC preventative maintenance can extend a unit’s lifespan, but if your system is nearing the end of its expected life, it may be time to consider a replacement. Your technician can review your options and help you determine if it may be time to upgrade.
Schedule Regular Maintenance: It’s recommended to have your AC inspected and serviced at least once a year, ideally before the cooling season begins, to ensure your system is ready to keep your home comfortable during the hottest months.

Preparing Your Home for Fall/Winter HVAC Maintenance

Preparing your home for fall/winter HVAC maintenance is essential as the colder months approach. Here’s a quick look at how to get started:

Schedule Regular Maintenance: We recommend having your heating system inspected and serviced annually, and it’s best to have these services performed before the colder season begins. Doing so will ensure your heating system is ready to keep your home warm and comfortable throughout the winter.
Check Your Heater: Before your technician arrives for an annual service, turn it on and ensure it produces warm air. Listen for any unusual sounds and check the thermostat for proper functioning. If you notice any issues, note them and inform your technician.
Clean Your Heater: A clean heating system will run more efficiently, so take the time to clear away any dust or debris from around the furnace or heat pump. Ensure nothing is blocking the airflow. Replacing or cleaning your air filter is also a good idea that can help improve your unit’s efficiency.
Know When to Upgrade: Heating systems, like furnaces and heat pumps, can last longer with proper maintenance. However, all systems eventually become outdated or sustain too much wear and tear to work properly. If your system is nearing the end of its expected lifespan or you experience frequent repairs, it might be time to consider a replacement.
