Summer in Middletown isn’t just hot—it’s humid. While most homeowners know how sticky and uncomfortable that can feel indoors, fewer realize how much of a toll high humidity takes on their HVAC systems.
At Aire Serv of Middletown, we often see HVAC performance issues that are directly related to excessive indoor moisture. Understanding how humidity affects your system—and how to manage it—can help you stay comfortable, protect your equipment, and lower your energy bills.
The Hidden Cost of Humidity
Your air conditioner doesn’t just cool your home—it also removes moisture from the air. But when humidity levels rise above 60%, even a properly functioning system can start to struggle. Here’s how:
1. Reduced Cooling Efficiency
High humidity makes your home feel warmer than it really is. As a result, your AC has to run longer and work harder to reach the temperature set on your thermostat, driving up energy usage and increasing wear on the system.
2. Short-Cycling or Constant Running
In extreme humidity, your system may start short-cycling (turning on and off too frequently) or running continuously without fully dehumidifying your home. Both can lead to discomfort and long-term damage to your HVAC system.
3. Increased Risk of Mold and Mildew
Too much moisture creates the perfect breeding ground for mold—especially in ducts, vents, and near the indoor unit. This can impact air quality and even lead to respiratory issues.
4. Premature Wear and Tear
When your system is constantly compensating for high humidity, components like compressors, coils, and motors wear out faster—leading to costly repairs or even early replacement.
How to Fight Back Against Humidity
There are several ways to keep indoor moisture under control and protect your HVAC system during the summer:
Schedule Routine Maintenance
A well-maintained system will operate more efficiently and handle humidity better. A professional tune-up includes checking refrigerant levels, cleaning coils, and inspecting drain lines to ensure moisture is being properly removed.
Consider a Whole-Home Dehumidifier
If your home consistently feels damp or muggy, a dedicated dehumidifier can work alongside your HVAC system to regulate indoor moisture levels—without overburdening your AC.
Use Your Thermostat Strategically
Set your thermostat to a steady temperature, avoid drastic changes, and use the “auto” fan setting rather than “on” to prevent unnecessary humidity buildup between cooling cycles.
Check for Air Leaks
Excess moisture can sneak in through poorly sealed windows, doors, and ducts. Sealing these gaps helps your HVAC system maintain better control over temperature and humidity.
Take Control of Your Comfort
Delaware summers can be relentless—but your home comfort shouldn’t be. If your AC is struggling to keep up or your home feels more muggy than cool, it’s time to take action.
