When summer temperatures rise in Charlotte, NC, your air conditioning system becomes one of the most important parts of your home. But with heavy seasonal use, your AC unit is at a higher risk of breakdowns, reduced efficiency, and expensive repairs. Fortunately, there are several steps you can take to keep your HVAC system running smoothly all season long.
At Ross & Witmer, we’ve been helping homeowners across the Charlotte area stay comfortable since 1945. Below are five essential tips to prevent HVAC repairs this summer and keep your home cool when it matters most.
1. Change Your Air Filters Regularly
One of the easiest and most effective ways to protect your air conditioning system is to replace your air filters on a regular schedule. Dirty or clogged filters reduce airflow, forcing your AC to work harder—and that added strain can lead to system malfunctions or early failure.
How often should you change your filter?
In most cases, every 1 to 3 months. However, if you have pets, allergies, or high system usage, monthly filter changes are recommended.
Clean filters not only improve cooling performance and extend the life of your unit but also help maintain healthy indoor air quality for your family.
2. Enroll in an HVAC Maintenance Plan
A professional HVAC maintenance plan is one of the best ways to avoid surprise repairs. At Ross & Witmer, our seasonal tune-ups are designed to keep your system in peak condition with comprehensive inspections, cleanings, and adjustments.
Our technicians will:
- Inspect and tighten electrical connections
- Clean condenser and evaporator coils

By staying ahead of wear and tear, you’ll enjoy better energy efficiency, fewer breakdowns, and longer system lifespan.

3. Keep a Consistent Thermostat Setting
Frequent thermostat changes may seem like a good idea, but drastically raising or lowering the temperature causes your system to work overtime. That can accelerate wear on components and raise your energy bills.
Instead, aim for a stable indoor temperature throughout the day. If you’re away from home, use a programmable or smart thermostat to gradually adjust settings. This reduces the workload on your AC unit and keeps your home comfortable while saving energy.
4. Look Out for Warning Signs of AC Trouble
Air conditioning problems don’t usually appear overnight. By recognizing the early warning signs, you can prevent a small issue from becoming a major repair.
Common signs of AC trouble include:
- Warm air or uneven cooling
- Unusual noises (rattling, banging, squealing)
- Weak airflow or blocked vents
- Unexplained increases in your energy bill
- Moisture or leaks around the system
If your system is struggling to cool your home or making strange sounds, don’t wait. Call the experts at Ross & Witmer to diagnose and fix the issue before it leads to a full breakdown.
5. Protect Your Outdoor Unit
Your outdoor condenser unit plays a crucial role in your HVAC system’s performance. To prevent damage and overheating, make sure it’s free of debris like leaves, grass, and dirt. Trim back plants and ensure there’s at least two feet of clearance on all sides for proper airflow.
You can also gently rinse the unit with a hose to remove dust buildup—but be careful not to bend the fins or damage components.
