Professional AC Repair and Maintenance
An AC system generally lasts between 15 and 20 years. Around age 10, it usually starts experiencing problems that require an AC repair. You may notice short-cycling, strange sounds, leaks, poor airflow, and other issues. It’s crucial not to delay professional assistance. Small problems can easily escalate into severe, costly ones. They can also result in permanent damage, reducing your system’s lifespan.

In between professional AC appointments, make sure you’re changing your air filter. A dirty, clogged filter can cause problems such as your system overheating, short cycling, and reduced lifespan. Experts recommend changing your filter out at least every three months. However, factors such as how many people live in your home and whether you have pets can necessitate more frequent filter changes. Many homeowners inspect their filters once a month to ensure they know when it is time for a fresh one.

Frequently Asked Questions
There’s a lot to know about your HVAC system, but expanding your knowledge can help you make informed decisions for your home. Here are a few common questions we often receive from East Alton homeowners.
What HVAC Services Do You Offer?
We offer a variety of HVAC services, including furnace repair, AC maintenance, heat pump installations, and boiler inspections. If you are building a new home, our experts can help you with HVAC design. We also provide indoor air quality solutions to make it easier to create a healthier, cleaner home environment.
How Often Should AC Maintenance Be Scheduled?
You should schedule AC maintenance once a year. We suggest calling us at the end of winter or in the early spring to book your appointment. If your system needs repairs, there’s still plenty of time remaining to complete them before the hot weather arrives in the area.
When Do I Need Furnace Repair?
Unusual noises, foul odors, short cycling, corrosion on the unit’s exterior, and inconsistent temperatures are signs your furnace needs attention. While those are serious, burning odors or a yellow pilot light are the most severe indicators. They require prompt emergency assistance by one of our trained professionals.
