As summer begins winding down, your air conditioner has likely been working overtime for months to keep your home cool and comfortable. After enduring weeks of high temperatures and humidity, it’s common for HVAC systems to start showing signs of wear. At McNally’s Heating & Cooling, the end of summer is one of our busiest times because many homeowners begin experiencing problems that could have been prevented with routine maintenance.
Here are some of the most common air conditioner issues we see as summer comes to a close:
- Frozen Evaporator Coils
A frozen air conditioner may seem surprising during warm weather, but it’s actually a common issue. Dirty air filters, restricted airflow, low refrigerant levels, or clogged coils can cause your system to freeze up. If you notice ice on your unit or warm air coming from your vents, it’s time to have it inspected before the problem worsens.
- Refrigerant Leaks
If your air conditioner isn’t keeping up with the heat or seems to run constantly, a refrigerant leak could be the culprit. Low refrigerant reduces your system’s cooling ability, causing it to work harder while increasing energy costs and the risk of further damage.
- Clogged Condensate Drain Lines
Your air conditioner removes gallons of moisture from your home throughout the summer. Over time, dirt, algae, and debris can clog the condensate drain line, causing water to back up into the system. This can lead to water damage, increased indoor humidity, and even trigger a system shutdown.
- Dirty Outdoor Condenser Units
After an entire summer of mowing, storms, and outdoor activity, your condenser can become surrounded by grass clippings, leaves, cottonwood, and other debris. Restricted airflow forces your air conditioner to work harder, reducing efficiency and putting extra strain on the system.
- Worn Electrical Components
Months of nearly continuous operation can take a toll on your system’s electrical components. Capacitors, contactors, and fan motors naturally wear over time. If your AC is making unusual noises, has trouble starting, or cycles on and off unexpectedly, these components may need professional attention.
Finish Summer Strong
As temperatures remain warm and your air conditioner continues working hard, now is the perfect time to address small issues before they become costly repairs. If you’ve noticed weak airflow, inconsistent cooling, unusual noises, or higher-than-normal energy bills, don’t ignore the warning signs.
