Why Is Maintenance So Important?

Why Is Maintenance So Important?
The purpose of preventative maintenance is to keep your HVAC system up and running all season long with no surprise breakdowns, while operating at top efficiency.
You rarely see your HVAC system face to face, so it’s easy to forget about it and neglect it. Imagine doing the same with your car. If you never have the oil changed or refuse to take your car in for any kind of tune-up until the check-engine light comes on, you can’t expect it to last more than a couple of years.
Your HVAC system is the same way. No matter how expensive the system is or what the manufacturer promises, a complicated piece of mechanical equipment is subject to breakdowns and needs repairs every so often. Reduce the incidence of repairs by keeping on top of annual maintenance.
Benefits of Annual HVAC System Maintenance

What can you expect from your newly tuned-up HVAC system? Is the cost of maintenance really worth it? You should consider that some benefits of regular maintenance are immediate while others prevent future problems from developing.


Some of the most prominent benefits include:
Lower energy bills: You might assume that since the equipment is heating or cooling your home without any apparent problem that everything is fine. However, have you taken a look at your energy bills lately? A neglected system slowly loses its ability to keep your home comfortable at the same level of efficiency it once did. Just as a car tune-up delivers better gas mileage, your HVAC system consumes less fuel after receiving professional maintenance.

Fewer repairs: Do you hear a strange sound or notice an odd odor coming from your furnace? Calling for a tune-up right away could help catch problems before they become disastrous. For example, a fraying belt could result in strange operating noises. If a technician replaces it in time, you can avoid the expensive repair that results from a snapped belt whipping around inside. By preventing future repairs, annual maintenance pays for itself

Lower chance of a catastrophic breakdown: Everyone wants an incident-free cooling and heating season. After all, it’s incredibly inconvenient and uncomfortable when equipment breaks down on a sweltering summer afternoon or frigid winter night, right when you need your HVAC system most. The odds of this happening when you schedule inspections every year are greatly diminished.

Longer equipment life: Air conditioners, furnaces and other HVAC equipment function best when they’re regularly serviced and cleaned. One malfunctioning part can cause a domino effect that causes the entire system to break down. Regular maintenance prevents this from happening and adds years to your equipment’s lifespan.

Safer equipment operation: A failing HVAC system does more than cost a lot of money to repair; it also can endanger your family. For instance, if the furnace develops a crack in the heat exchanger, carbon monoxide gas can escape and poison the air you breathe. Also, electric HVAC systems can develop a short circuit, which is a serious fire hazard if ignored. Clearly, your family’s safety is yet another reason to schedule annual HVAC system maintenance.


Maintenance Tasks You Can Do Yourself

Plan to schedule annual HVAC system maintenance once in the spring for your cooling equipment and again in the fall for your heating system. If you have a heat pump, the combined heating/cooling system should receive maintenance twice a year.
Plan to perform a few maintenance tasks of your own between these formal visits. The following DIY tasks help keep your equipment running smoothly until the next professional visit:
Change the HVAC air filter every month. Some units have an indicator light that tells you when the filter is beginning to become clogged and blocking airflow.
Remove debris from around the outdoor unit.
Hose down the outdoor unit when dirt begins to accumulate on it.
Trim back foliage to at least 18 inches from the outdoor unit.
Keep supply and return registers unblocked by drapes, rugs or furniture.

Maintenance You Should Leave to the Pros

Many homeowners wonder why they can’t just complete an entire tune-up themselves. The fact is a thorough tune-up requires skills, tools and knowledge that only experienced HVAC technicians can deliver.
Here’s what to expect when you call in the pros to perform annual HVAC system maintenance:


Check the thermostat: The tech makes sure the thermostat is calibrated correctly to ensure comfort in every season. If you don’t have a programmable thermostat installed, the technician may recommend
one and install it for you on the spot.

Tighten electrical connections: Loose connections are dangerous and can cause improper operation that shortens the equipment’s lifespan. The technician also measures voltage and current on equipment motors.

Lubricate all moving parts: Lack of lubrication causes high amounts of friction in the system. This can cause it to overheat and break down. Adding lubrication helps parts move smoothly against one another, decreasing electricity use and lowering your energy bills.

Inspect the condensate drain: Cooling equipment and condensing furnaces produce condensate when they operate. Under normal conditions, the condensate collects in a pan and drains away to the outside. However,
over time sludge or algae can form in the drain pipe and create a blockage. During times of high usage, the drain pan may overflow and cause water damage to the equipment or your home. A technician checks the
condensate drain to make sure it’s draining properly and cleans it out if necessary.

Check system controls: The start cycle, operation and shut-off sequence should occur in a particular fashion. The technician checks the controls to make sure everything is operating safely and properly.
Clean and adjust the blower: Issues with the blower can decrease equipment efficiency by up to 15 percent. Making adjustments ensures proper airflow and ample home comfort.

Clean the condenser coils (cooling specific): Soiled coils slowly decrease efficiency and make the equipment run longer. Cleaning the coils annually is an important part of maintaining the A/C’s capacity, ensuring lower energy bills and prolonging equipment life.

Check refrigerant charge (cooling specific & heat pump): If the air conditioner was charged too high at installation, you could be paying much more than necessary to cool your home. An undercharged system also can develop if the system has a leak. A technician checks for these circumstances, repairs any leaks that are present, and recharges the system if necessary.

Check fuel line connections (heating specific): Poor gas connections are a fire hazard. They can also cause health problems if fumes are able to escape into your home. Tightening the connections ensures safe operation.

Inspect the gas pressure, burner combustion and heat exchanger (heating specific): Incorrect pressure, a dirty burner or a cracked heat exchanger can result in improper burner operation. These circumstances also can cause unsafe and inefficient operation. Adjusting the pressure and cleaning the burner are two viable options to improve operation and lower your heating bills, but if the heat exchanger is cracked, it’s likely you’ll need to purchase a new furnace.

Many furnaces break down because of lack of maintenance. Similar to how your car should get an oil change, your furnace should receive a tune-up once per year. When you schedule an annual heating tune-up, you could see:
Increased efficiency – As part of our inspection checklist, we will make sure your furnace is working at its peak performance levels to ensure it can reach maximum power efficiency.
Lower energy bills – One of the first signs your unit isn’t working properly is a spike in monthly energy bills. Annual maintenance ensures your unit is clean and not working harder than it needs to.
Longer lifespan – When you schedule annual maintenance, you can expect your unit to last longer with fewer major breakdowns.
Fewer breakdowns – Many common breakdowns can be avoided if the unit was properly taken care of. Avoid costly breakdowns and schedule annual maintenance.
