Summer is officially here, and we all know how important a well-functioning air conditioner can be during the hot season. However, what if you switch on your AC and it starts running but doesn’t cool your home? Don’t worry; this is a common problem many homeowners face. It can be easily resolved with the help of an experienced HVAC professional.
1.Dirty Air Filters
One of the most common reasons an AC runs but doesn’t cool is dirty air filters. When the air filters are clogged with dirt and debris, the air does not flow freely through the system, causing the AC to work harder than usual. This will not only lead to inefficiency but can also damage the compressor. Our experts can handle this issue by cleaning or replacing your air filters.
2.Low Refrigerant Levels
Another reason why your AC may not be cooling as it should be is due to low refrigerant levels. If there isn’t enough refrigerant in the system, it can cause the AC to run but not cool. This issue requires professional help. At Medcalf Heating & Cooling, we have the expertise and experience to diagnose and repair this issue.
3. Faulty Condenser Unit
Your condenser unit is an important part of your AC system. In simple terms, the outdoor unit is responsible for discharging the heat that your AC unit has removed. It has a fan, a refrigerant-filled coil, and a pump to remove heat from your home. If this unit is not working properly, the AC will run but not cool.
More than one thing can go wrong with a condenser unit that can cause your AC to run but fail to cool your house. The most common issue is a lack of HVAC maintenance, which can impact the unit’s overall efficiency over time. Other issues include refrigerant leakage, a damaged compressor, a faulty thermostat, or a failed fan motor.
If you suspect that your condenser unit is why your AC is not cooling your home, it’s time to call a professional. Our skilled technicians will inspect your unit and determine the exact issue. They’ll conduct tests to confirm what’s wrong and then repair or replace the faulty parts.
4. Inefficient Thermostat
The thermostat’s primary function is to control and regulate your AC’s cooling cycle. However, your AC will run inefficiently if the thermostat fails or starts providing false temperature readings. In such a case, the AC runs continually without realizing that the room has reached the desired temperature. An overworked AC unit increases energy bills considerably while failing to deliver the desired cooling.
A malfunctioning thermostat is an issue that most homeowners fail to detect. Many homeowners assume that their thermostat works efficiently because it functions normally, unknowingly diverting their efforts to other AC components such as the compressor or refrigerant. An inefficient thermostat can lead to costly repairs.
One of the primary causes of a faulty thermostat is outdated technology. The first-generation thermostats need more sensors and positioning for accurate temperature readings. On the other hand, new Wi-Fi thermostats read temperatures with greater precision and incorporate features that save energy and enhance comfort.
Another cause of faulty thermostats is inaccurate positioning. Thermostats must be placed away from direct sunlight, windows, or radiators to read room temperatures accurately. Poor positioning compromises the thermostat’s ability to realize whether or not your home is cool enough to cycle off the AC compressor.
5. Blocked Air Ducts
Blocked air ducts can also lead to your AC not cooling your home efficiently. When the ducts are blocked with dust and debris, the air cannot flow freely, leading to inefficiency. Our team can clean your air ducts, ensuring that the air flows freely and that your AC cools your home effectively.
