Kombi's technician tightening a screw in an AC unit

When summers start heating up, the last thing you want is your air conditioner not working the way it should. At Kombi’s Heating and Cooling, we’ve been helping homeowners throughout the Portland OR and Vancouver WA areas stay comfortable with professional maintenance services.

We know that inviting someone into your home to work on your system can feel a little awkward, especially if you’ve had less-than-great experiences in the past. That’s why we focus on making the whole process easy, honest, and stress-free. No confusing jargon. No pressure tactics. Just straightforward AC maintenance services designed to keep your system running at its best.

Maybe your system is blowing warm air. Maybe your energy bills have crept up for no obvious reason. Or maybe it’s making that weird noise you’ve been trying to ignore. Here’s the thing: most AC problems don’t happen overnight. They build up over time when routine air conditioning maintenance gets pushed to the back burner.

And we get it, life is busy. It’s easy to forget about your cooling system when everything seems fine. But a little attention now can save you a lot of headaches (and money) later.

What Our Air Conditioning Maintenance Includes

When you schedule AC maintenance service with Kombi’s Heating and Cooling, we perform a thorough inspection of your entire system. Not just a quick glance and calling it good. We take the time to check all the key components and make sure everything is working the way it should by:

Looking at electrical connections, refrigerant levels, thermostat calibration, and all the parts that keep your AC running smoothly.
Handling filter replacement. A clean filter is one of the simplest but most important parts of air conditioning system maintenance. Clogged filters restrict airflow and make your system work harder, driving up energy costs and potentially causing damage.
Cleaning components, including dirt and debris accumulated on coils, fans, and other parts. This helps improve efficiency and prevents problems caused by buildup.
Performing efficiency testing and adjustments to make sure your system is operating at peak performance. If something is off, we’ll make the necessary tweaks to get it back on track.
Providing honest recommendations. If we notice something that needs attention, we’ll let you know. And if everything looks great? We’ll tell you that too.

Our $99 Tune-Up Special

For just $99, we’ll give your air conditioning system a thorough once-over. Our tune-up special includes a full system inspection, filter replacement, component cleaning, efficiency testing and adjustments, and honest recommendations if anything needs attention.

This is a great way to get your system ready for summer or address any concerns you’ve been having. And remember, catching issues now can prevent costly repairs down the road.

Why Do I Need Air Conditioner Maintenance?

Think of AC maintenance like an annual checkup for your car. You wouldn’t drive for years without changing the oil, right? Your air conditioning system works the same way.

Without routine service, cooling systems can experience unnecessary wear on important components over time. Parts start working harder than they need to. Efficiency drops. And before you know it, a small issue has turned into a big, expensive repair.

Regular air conditioning system maintenance helps reduce strain on your equipment. It keeps everything running efficiently, which means lower energy bills and fewer surprise breakdowns.

And let’s be honest, AC emergencies always seem to happen at the worst possible time, like during the hottest week of the summer or right before you’re hosting family.

How Often Should I Schedule AC Maintenance?

We recommend scheduling professional AC maintenance at least once a year to help keep your cooling system operating efficiently before warmer temperatures arrive. Air conditioners can lose efficiency and develop hidden issues when maintenance is delayed for too long.

Spring is usually the best time to schedule your air conditioning unit maintenance. Getting ahead of the summer rush means you won’t be stuck waiting for service when everyone else is scrambling.

Signs Your System Needs Professional AC Maintenance

Weak airflow is one of the most common red flags. If the air coming from your vents feels weaker than usual, it could mean your filter is clogged, your ductwork has issues, or your blower motor is struggling.
Unusual noises are another sign to pay attention to. Your system should run relatively quietly. Grinding, squealing, banging, or rattling sounds often indicate something mechanical is going wrong.
Rising energy bills without a change in your usage habits can point to an efficiency problem. When your air conditioning system isn’t maintained properly, it has to work harder to cool your home. That extra effort shows up on your utility bill.
Uneven cooling throughout your home is frustrating. One room feels like an icebox while another stays stuffy and warm. This can be caused by ductwork issues, refrigerant problems, or even a system that’s not sized correctly for your space.
Excess moisture or leaks around your unit shouldn’t be ignored either. Some condensation is normal, but pooling water or excessive moisture can indicate a drainage problem or refrigerant leak.

DIY Tips for Your Air Conditioning System

While annual professional AC maintenance is essential, there are some simple things you can do throughout the year to help your system run efficiently. Think of these as ways to support your cooling system between tune-ups:

Change your filters regularly. This is probably the single most important thing you can do as a homeowner. Most filters should be replaced every one to three months, depending on the type and your household conditions. If you have pets or allergies, you might need to change them more often. A clean filter keeps airflow strong and prevents dirt from building up inside your system.
Keep the area around your outdoor unit clear. Your condenser or compressor needs room to breathe. Trim back any plants, bushes, or debris that might be crowding it. Aim for at least two feet of clearance on all sides. This helps your system expel heat efficiently.
Make sure your vents are open and unobstructed. It might seem logical to close vents in unused rooms to save energy, but this can actually create pressure imbalances that make your system work harder. Keep vents open and make sure furniture, curtains, or rugs aren’t blocking airflow.
Use a programmable thermostat or timer. Setting your thermostat a few degrees higher when you’re away from home can reduce strain on your system and lower your energy bills. You don’t need to cool an empty house to 68 degrees. Smart thermostats make this even easier by learning your schedule and adjusting automatically.
Check for obvious issues around your unit. Take a quick look at your indoor and outdoor equipment every now and then. If you notice ice forming on the coils, water pooling where it shouldn’t be, or anything that looks off, give us a call. Catching problems early can save you from bigger headaches later.
Consider upgrading older equipment. If your system is more than 10 to 15 years old and you’re constantly dealing with repairs or high energy bills, it might be time to think about a replacement. Newer systems are significantly more efficient and can save you money over time. We offer free estimates to help you weigh your options.

When Should I Call a Professional?

Anything involving refrigerant, electrical components, or internal system parts should be left to trained technicians.

Refrigerant handling requires special certification, and working with electrical systems can be dangerous without the right knowledge and tools. Attempting these repairs yourself can void warranties, cause further damage, or create safety hazards.

You should also call for professional air conditioning maintenance services if you notice any warning signs, like weak airflow, strange noises, rising bills, uneven cooling, or excess moisture. These issues often have causes that aren’t visible or accessible without proper equipment and expertise.

And of course, if your AC stops working entirely, don’t suffer through the heat. AC emergencies don’t care about your schedule, and at Kombi’s Heating and Cooling, we offer 24/7 emergency service with no after-hours or weekend fees.
