Signs of a Broken Evaporator Coil in Moreno Valley, California

At Inland Empire Comfort, we address this problem frequently and can quickly pinpoint the signs of faulty equipment. Find out when you need to schedule air conditioning repair services.
1. Warm Air Wafting From the Vents
You expect warm air from vents when you operate your furnace. However, it's frustrating when you need relief from Moreno Valley's hot temperatures and can't keep your house cool because of a faulty air conditioner. Adjust your thermostat settings to confirm your system is set to "Cool" and a few degrees lower than room temperature.
Is your air conditioner not cooling despite making these adjustments? If warm air continues to fill the space, your cooling system needs a professional inspection. A licensed technician can pinpoint the root of the problem and recommend long-lasting solutions, such as AC evaporator coil replacement.
2. Unexplained Spikes in Your Energy Bills
Let's say you leave your thermostat at 68 degrees, and the air conditioner runs accordingly. By doing so, you should see your monthly energy bills remain mostly the same each billing cycle. However, if one month brings a significantly higher bill despite no change in your cooling habits, it could indicate that your system isn't working as efficiently as it should.
A broken evaporator coil may be responsible for the sudden hit to your wallet. Don't compromise your comfort just to save some money. Let an expert evaluate the air conditioner and keep it operating at peak efficiency.
Basic maintenance, repairs, or even system replacement can increase HVAC efficiency and save you money in the long term.
3. Ice-Covered Coils Around Your Moreno Valley Cooling System
Given that you rely on HVAC equipment to cool your home, you might think that ice build-up on indoor coils means it's doing its job. In reality, frozen components spell trouble. The ice insulates the coil and prevents it from trapping heat from inside your home.
As a result, rooms may feel warmer and more humid because of the malfunctioning equipment. Dirt and debris on the surface can exacerbate this problem, so contact a professional for a coil cleaning service and HVAC tune-up.
4. Leaking Refrigerant Around the Air Conditioner
Without refrigerant, your cooling system can't transfer heat inside your home and return it as refreshing, cool air. This chemical substance plays a key role in keeping your space comfortable amid Moreno Valley's hot, arid climate. When you have a broken evaporator coil, the refrigerant may start to leak from the unit.
HVAC technicians must address this issue right away to prevent the following:
- Health and safety risks due to chemical exposure
- Widespread system malfunctions
- A decrease in cooling efficiency

Invest in regular air conditioning maintenance to prevent refrigerant leaks and other costly problems.
5. Air Conditioning Short Cycling
Does your cooling equipment turn on for a minute or two and then immediately shut off in a repeated cycle? This issue, known as short cycling, poses many problems for homeowners, including:
- Uncomfortable indoor environment
- Decreased HVAC efficiency
- Greater risk of system breakdown
For fast relief, reach out to a
licensed HVAC contractor. They'll inspect all internal components to rule out issues like faulty wiring, a bad capacitor, or low refrigerant levels. In many cases, repairing or replacing the unit's coil can alleviate the problem and give you peace of mind.

Identifying a broken evaporator coil in your home's cooling system can be as simple as monitoring changes in your energy bills, overall comfort, and system performance.
