As summer rolls into Southwestern Ontario, you might have air conditioner maintenance in the back of your mind. If you’ve already been running your AC unit without maintenance, you could be setting yourself up for higher bills, poor performance, or even a costly repair.
At Postma Heating and Cooling, we have performed air conditioner maintenance and repair services on thousands of AC systems in Chatham-Kent and the surrounding areas over the years. Most issues we see are clogged coils, airflow problems, and low refrigerant. These all could’ve been prevented with a little routine care. The good news? A single tune-up can make a major difference.
The Cost of Skipping Air Conditioner Maintenance
Your air conditioner might still be working, but that doesn’t mean it’s working efficiently. Dirt buildup, electrical wear, and even something as small as a blocked vent can cause the system to run longer, strain harder, and burn more energy. That extra workload leads to higher electricity bills and faster wear on key components.
In fact, Hydro One confirms that regular maintenance, especially filter replacement and outdoor unit cleaning, can reduce energy consumption by up to 10%. Those kind of savings can really add up across a long Ontario cooling season.
What to Expect During a Professional AC Tune-Up
Our licensed technicians go far beyond a quick look. When you book an air conditioner maintenance visit with Postma, we conduct a full performance check, including refrigerant pressure, electrical testing, coil cleaning, and thermostat calibration. We’ll also inspect your ductwork and drain lines to catch anything that might cause long-term damage or water leaks. We also suggest duct cleaning for homes we notice visible dust and debris clogging their HVAC system.
Each service visit ends with a clear maintenance report, so you know exactly what was done and how your system is working.
What You Can Do Between Visits
While professional service is essential, there are a few habits you can adopt to support your AC’s performance. Replacing your filter regularly, keeping vents unblocked, and clearing plant growth around the outdoor unit all help your system breathe easier.
When to Book Air Conditioner Maintenance
Warm airflow, inconsistent temperatures, odd smells, or a system that never shuts off—these are all signs that something’s off. Even if your system is still cooling, it could be under stress. Letting it run that way could lead to compressor failure or damage to your blower motor which are both costly repairs.
The sooner you address performance issues, the easier (and cheaper) they are to fix. If you’re looking to make energy efficiency upgrades, Enbridge Gas also offers rebates and resources for homeowners investing in system performance and long-term savings.
