AC Services for Homeowners: System Maintenance Checklist Guide

Your AC system is the hardest working appliance in your home.

It operates thousands of hours each year, fights dust, humidity and summer heat waves — and most homeowners never think twice about it. That is, until it fails on the hottest day of the year.

Here’s the problem:

Many folks think of AC services as a “when it breaks, fix it” situation. However, a simple maintenance checklist could save you thousands in repair costs and keep your system running years longer.

Here is a detailed maintenance checklist that homeowners should be performing on their AC system.

Let’s jump in…

Here’s what’s inside:

Why AC Services Matter More Than You Think

AC services help you save money, protect your investment and keep your home safe. Not just provide comfort. So why do the majority of homeowners completely neglect this simple home maintenance chore?

Check out these numbers:

According to statistics, only 42% of homeowners will have a professional conduct routine maintenance on their AC unit. That is shocking given how much we rely on these systems.

And here’s the kicker…

Air conditioners that receive regular HVAC   maintenance last 40% longer. That means almost twice as long by just booking routine maintenance appointments.

But if that still hasn’t convinced you, consider this: homeowners spend more than $7,000 annually on maintenance and repairs for their homes — and unexpected HVAC issues make up a large portion of that budget. When you need AC services, you really should use a company like Farrell AC   to take care of preventative maintenance before problems start. After all, a little service call today is far cheaper than replacing the whole system tomorrow.

That’s a no-brainer.

Regular AC maintenance also:

• Lowers monthly energy bills
• Improves indoor air quality
• Reduces the risk of emergency breakdowns
• Keeps the manufacturer’s warranty valid

Neglecting maintenance is like skipping oil changes for your car. It will probably be okay for a while… until things start falling apart.

The Ultimate AC Maintenance Checklist

Okay, now onto the good stuff. This complete AC services checklist is what every homeowner should follow. Complete it in order — remember some things are monthly, others seasonal, and others only once-a-year tasks.

Replace Or Clean Your Air Filters

Changing your filter is the single most important thing you can do. It reduces airflow, makes your system work harder, and decreases your efficiency.

Inspect your filter monthly. Change non-washable filters every 1-3 months. Clean washable filters by washing with warm, soapy water.

Clean The Outdoor Condenser Unit

Weeds, grass, dirt and debris all pile up on your outdoor unit. That nasty stuff prevents your system from dispersing heat.

Here’s what to do:

• Turn off the power at the breaker
• Remove any leaves, twigs, and debris from around the unit
• Gently spray the fins with a garden hose
• Keep at least 2 feet of clearance around the unit

Check And Clean The Indoor Coils

Your evaporator coil resides within your air handler. As the years go by it becomes covered in dust and debris that inhibits its performance. A dirty coil = warm air, longer run times and increased electric bill.

The average homeowner should NOT attempt this. The coil is delicate.

Clear The Condensate Drain Line

The drain line removes humidity produced by your system. If algae or mold build up in your drain line, water can pool and cause extensive damage to ceilings, walls and floors.

Dump a cup of white vinegar down your drain line every few months. This will kill algae and ensure it continues to flow.

Inspect The Ductwork

Leaky ducts can lose up to 30% of the cool air   your system generates. That’s money right there going into your attic.

Walk around your home and check accessible ducts for:

1. Visible holes or tears
2. Disconnected joints
3. Crushed or kinked sections
4. Sagging flex duct

Use mastic sealant or metal tape to patch small leaks. Hire a professional to fix larger ones.

Test The Thermostat

The thermostat is the hub of everything. If it doesn’t sense temperature accurately, nothing else will function properly.

Try it out by programming a temperature set point and see if cycles on and off as it should. If you still have one of those old dial thermostats, upgrading to a smart one is a no-brainer.

Check Refrigerant Levels

Low refrigerant is a leading cause of ACs not cooling right. However… refrigerant recharge is NOT a DIY task.

This is a professional service. Refrigerant is a controlled substance. Mishandling will hurt your system or environment.

Listen And Watch For Problems

This is the easiest thing on the list — and likely the most neglected. Listen to how your AC sounds and operates each time you turn it on.

Watch out for:

• Strange noises (banging, hissing, grinding)
• Weak airflow from the vents
• Warm air coming out
• Strange smells
• Unexpected spikes in your power bill

Catching a small problem early can save you thousands in repair costs later.

DIY Tasks vs Professional AC Services

Not every maintenance task needs a professional. But some absolutely do.

DIY vs Professional: Here’s a quick guide.

DIY tasks:

• Replacing air filters
• Cleaning around the outdoor unit
• Clearing the condensate drain line
• Testing the thermostat
• Visual inspections

Professional AC services:

• Deep coil cleaning
• Refrigerant checks and refills
• Electrical component testing
• Compressor and motor servicing
• Ductwork sealing and repair

“If it has to do with refrigerant, electrical parts, or opening up your system — hire someone. The savings you think you get by doing these yourself will vanish when you damage your system.”

How Often Should You Service Your AC?

The majority of manufacturers advise having your AC system serviced twice yearly. Once during spring before it gets hot and once during fall when the cooling season is over.

A typical professional service visit includes:

• Full system inspection
• Coil cleaning
• Refrigerant level check
• Electrical component testing
• Lubrication of moving parts
• Thermostat calibration
• Ductwork inspection

What about price? Routine tune ups are about $150-$300 per visit. It’s one of the best things you can do for your home when you consider that AC replacement costs $8,000-$15,000.

Final Thoughts

Your AC system isn’t something you should neglect. (It’s too important and expensive.) Regular maintenance means your system lasts longer, your bills stay lower, and your home stays cooler all summer.

To quickly recap:

• Check and replace filters every 1-3 months
• Keep the outdoor unit clean and clear
• Flush the drain line every few months
• Schedule a professional service twice a year
• Pay attention to any warning signs

Most homeowners neglect routine AC services because they never think about their system until it stops working. Don’t be that homeowner. The ones who write the maintenance checklist are rewarded with 15-20 years out of their AC system…

…while everyone else is calling for emergency repairs in the middle of July.

Begin with the checklist above. Complete DIY tasks this weekend and schedule your next service call today. Your AC (and wallet) will thank you.
