When Minnesota summers get hot and humid, you rely on your air conditioning system to keep you cool and comfortable. Unfortunately, an HVAC unit could wear out gradually with usage, leading to inadequate performance.
There is nothing as bad as when your air conditioner goes out unexpectedly. If your AC has stopped working or is simply not operating as well as it once did, you need to contact a professional heating and AC repair technician. At Blue Ox Heating & Air, we offer quality heating and AC repair services to the entire Minneapolis, MN area. We can make sure that your home’s HVAC unit is operating as efficiently and smoothly as possible.
Here are common problems that require the help of a heating and AC repair specialist.
Clogged or Dirty Filter
A liquid line filter drier helps to keep water and dirt out of the compressor. When the AC filters are clogged, they cause your air conditioner to freeze up and reduce the air volume that can pass through. This can reign havoc on your HVAC system and also cause the heater to stop.
Clogged filters reduce the AC’s efficiency and make your unit work harder to cool your home. The air that passes through may not be adequately filtered too. Common signs of a faulty AC air filter include reduced airflow from the AC vents and a denser filtration membrane.
A clogged or dirty filter can reduce the amount of clean air in your home, messing with your indoor comfort. Therefore, you need to get your air conditioning filter replaced as soon as possible by a qualified heating and AC repair technician.
Corroded Evaporator Coils
Air conditioners use an indoor evaporator coil and an outdoor condensing coil. The air conditioner evaporator coil consists of an A-frame network of copper coils. Its job is to absorb heat from the air within your house.
Over time, the refrigerant flowing through the evaporator’s coils wears down the inner lining. The cause is most typically environmental pollutants, which range anywhere from salt-air to formaldehyde. Another common corrosion source is the accumulation of specific particles on the external lining of an evaporator coil. The result is formic acid, which promotes the formicary corrosion of the copper coils. This can lead to various AC problems including leaking air ducts and frozen evaporator coils.
Sometimes, a lousy HVAC evaporator coil leads to people replacing their whole HVAC unit. That’s why you need to contact a qualified AC repair company like Blue Ox Heating & Air to help you determine the best course of action. As experts in AC repair in Minneapolis, MN, we’ll examine the evaporator coils and make the necessary repairs.
Dirty Condenser Coils
Condenser coils make sure your unit is reliable, effective and cost-efficient. However, they can become clogged due to outdoor elements like dirt. Dirty condenser coils can have a significant impact on the way your Ac system operates. For instance, your AC will require 30% more energy to cool your home if the condenser coil is dirty. But how quickly they get dirty depends on how often you use your HVAC unit.
If your AC unit doesn’t cool the air around you, then you might have a problem with the condenser coil. The best course of action is to contact us. As a leading heating and AC repair expert, we know the right way to clean an air conditioner’s outdoor coil.
Cracks in the coils that transport the refrigerant can lead to an AC refrigerant leak. Refrigerant leaks are one of the most dangerous things that can happen to a system that’s supposed to keep your house cool. Although it’s odorless, being exposed to a refrigerant gas can cause damage to your lungs. For this reason, refrigerant leaks should be handled by qualified heating and AC repair technicians.
Knowing the signs of a refrigerant leak is key to restoring your HVAC unit to working condition. One of the most common signs of a refrigerant leak is an oil residue. Another sign of a leak is warm air coming out of your air conditioner’s frozen evaporator coils. When it comes to repair, comprehensive knowledge and skill sets are required.
Electric Control Failure
There are six leading causes of electric motor failures; over-current, low resistance, overheating, dirt, moisture and vibration. Some electrical issues can stem from broken electrical parts and faults in the electric control system.
As the AC control switch is what powers and controls the AC compressor, any problems with it can dramatically affect the AC. You need to act fast and call a heating and AC repair expert who can take care of the many underlying electric problems that cause AC failure. A professional will also access the control unit wiring harness and repair the controller to your satisfaction.
The sensor plays a direct role in the automated function of the AC system. When the switch fails or has an issue, it can cause problems with the AC’s functionality. An AC compressor that doesn’t activate is a common symptom of a problematic AC sensor. If you’re inexperienced or unsure if your sensor is causing AC problems, call a heating and AC repair specialist.
