Is Your AC Ready for Warmer Weather? 7 Essential Maintenance Tips for Highlands Ranch Homeowners.
Expert Tips

As the temperatures in Highlands Ranch begin to rise, ensuring your AC is in peak condition is essential for maintaining a cool and comfortable home. The last thing you want is for your air conditioner to break down on a sweltering summer day. Fortunately, a little maintenance can go a long way in preventing costly repairs and ensuring energy efficiency.
At Top Shelf Electric, Heating, & Plumbing, we specialize in keeping your home comfortable year-round. Here are 7 essential AC maintenance tips to help you prepare for the warmer months ahead.
1. Change or Clean Your Air Filters
One of the easiest and most effective ways to keep your air conditioning system running smoothly is by changing or cleaning your air filters regularly. Dirty filters restrict airflow, making your system work harder and leading to increased energy costs.
How Often Should You Change Your Filter?
- Every 1–2 months during peak cooling season
- More frequently if you have pets, allergies, or live in a dusty area
- Check monthly and replace as needed to maintain efficiency
By keeping your air filters clean, you can improve indoor air quality and prevent unnecessary strain on your system.
2. Schedule a Professional Air Conditioning Tune-Up
Preventative maintenance is key to avoiding breakdowns and extending the lifespan of your air conditioning system. A professional AC tune-up includes:
- Inspecting and cleaning coils
- Checking refrigerant levels
- Ensuring all components are functioning properly
- Identifying and addressing minor issues before they become major repairs
At Top Shelf Electric, Heating, & Plumbing, our expert technicians provide thorough AC maintenance to ensure your system is running at peak performance. Call us today to schedule your tune-up.
3. Clear Debris Around Your Outdoor Unit
Your outdoor AC unit, also known as the condenser, needs proper airflow to function efficiently. Over time, dirt, leaves, and debris can accumulate around the unit, restricting airflow and reducing efficiency.
What You Can Do:
- Remove leaves, grass clippings, and debris from around the unit
- Trim back shrubs and plants at least 2 feet away
- Hose down condenser coils to remove dirt buildup (power off first)
Keeping the area around your AC unit clear ensures optimal airflow and efficiency during the hottest months.
4. Check Your Thermostat Settings
Your thermostat plays a crucial role in maintaining comfort while also keeping energy costs low. Make sure your thermostat is functioning correctly and programmed for efficiency.
Pro Tips for Thermostat Efficiency:
- Set to 78°F when home and higher when away
- Use a programmable or smart thermostat
- Upgrade to a Wi-Fi-enabled smart thermostat for better control
A properly set thermostat helps you save on energy bills without sacrificing comfort.
5. Inspect and Clean Air Ducts and Vents
Your AC relies on clean and efficient ductwork to distribute cool air throughout your home. Dust, dirt, and pet dander can build up in your ducts, leading to poor airflow and reduced air quality.
- Vacuum vents regularly
- Ensure furniture and curtains aren’t blocking airflow
- Schedule professional duct cleaning if needed
Clean ducts improve cooling efficiency and create healthier indoor air.
6. Check for Refrigerant Leaks
Your AC system relies on refrigerant to cool your home. If you notice poor cooling, it may indicate a leak.
Signs of a Refrigerant Issue:
- AC blowing warm air
- Ice buildup on refrigerant lines
- Unexplained spikes in energy bills
If you suspect a refrigerant issue, call a professional immediately. Our technicians at Top Shelf can diagnose and repair leaks to restore your comfort.
7. Listen for Unusual Noises
Your AC should run quietly. Strange noises often indicate problems.
Common Noises and Their Causes:
- Grinding or squealing – worn-out motor bearings
- Banging or rattling – loose components
- Hissing – possible refrigerant leak
Addressing unusual sounds early can prevent more expensive repairs down the road.
