Air Conditioning Service: What’s Wrong With Your Air Conditioner? | St. Paul, MN

Sometimes the only way to beat the heat of summer is to relax at home. But if your air conditioner isn’t working right, you may feel like there’s no escape.

When your air conditioner is not keeping your house cool, you need a professional air conditioning service to resolve your problem. Here is a look at some of the most common reasons your air conditioner isn’t working.

The Air Conditioner Won’t Turn On

If you can’t get your air conditioner to come on, you may have a problem with your thermostat. The thermostat controls the temperature according to your setting. Without a working thermostat, your air conditioner cannot work.

Check your settings, to make sure they are where you want them to be. To see if the thermostat is the problem, set the temperature a bit lower. Check your breaker box for a breaker that has tripped or a circuit that has blown.

Your problem could also be in the wiring. Your St. Paul, MN air conditioning service will be able to get to the root of the problem quickly and offer an estimate for repairs.

No Air Is Coming Out of the Vents

If there is no air coming from the registers, the fan outside may not be running. The first thing to check is the breaker box. You may have simply tripped a breaker.

If resetting the breaker doesn’t help, you may need a new blower belt. Your air conditioning service can replace your blower belt quickly, if that is the problem.

Other possible causes for no air to come from the vents include problems with your wiring, control board, or thermostat. There is also a chance that your condensate pump’s reservoir is full.

With a reliable air conditioning service on your side, you don’t have to track down the problem by yourself. They will be able to find the source of the issue quickly and get your air conditioner up and running soon.

The Air Conditioner Is Running But Not Cooling the House

This is one of the most frequent repair issues that an air conditioning service deals with. The list of possible reasons for this is varied and longer than many issues.

Before you start looking for repair problems, though, you might want to check to see if your air conditioner is the right size. If your unit is too small for the area it is cooling, it will not be able to provide proper cooling. To find out what size air conditioner you need to cool your home, check with your air conditioning service for information.

One problem with using an air conditioner that is too small is that it will likely seize, due to the extra stress of running constantly. Invest your money wisely, and get advice from a professional before buying.

If you have the proper unit for your space, you could have poor cooling because of a dirty air filter, blocked condensate drain, or low coolant level. Your outdoor compressor could be dirty, or your coils could be frozen. Whatever the issue, your air conditioning service can find it and offer advice on ways to avoid problems in the future.

The Air Coming Out of the Register is Hot

What could be worse than expecting a cool blast of refreshment and getting hot air blown in your face? This is probably related to the refrigeration circuit and you should check the following items: is the outdoor unit running, check the filter, check the setting on the thermostat. 

You should also check the outside unit to make sure it isn’t clogged with dirt and leaves. If that isn’t the issue, you may be low on coolant. Without the precise amount of refrigerant, your air conditioner cannot produce the results you need. Your air conditioning service can make sure you have the right amount of coolant to keep you comfortable.

The Compressor Won’t Turn On

If your compressor isn’t running, it could be due to several issues. You could have a defective start capacitor, which is needed to start your compressor. Or you may have a burned wire or a faulty compressor.

Whether you need repair or replacement, you should always have a dependable, professional air conditioning service do the work. That is the only way you are guaranteed the results you deserve.

The Fan Isn’t Running

If the fan in your outdoor unit stops working, your air conditioner cannot cool your home. You can try resetting it, but if that doesn’t help you may need to have the capacitor replaced.

There Is a Strange Noise Coming from the Air Conditioner

All air conditioners make some noise, even the most quiet of units. But if your air conditioner is making strange noises that you haven’t heard before or sounds louder than normal, you may need to call a service for help.

Often, a noisy air conditioner is due to a condenser fan motor problem, especially if it makes a squealing noise. Your condenser fan motor could be out of alignment, which your professional can adjust for you. Or you could need a condenser fan motor replacement, which is a quick fix for a professional.

If it’s not the belt, it could be an issue with the motor. A grinding noise signals an issue with the bearings.

The Unit Keeps Switching On and Off

If your air conditioner is doing this, there is definitely a problem. This could be because of a blocked or dirty condenser unit or a dirty evaporator. Make sure to keep debris from clogging your condenser unit to avoid a host of issues.

The Air Conditioner Coil Is Frozen

Something frozen usually makes things cooler. Not in the case of your air conditioner coil, however. When it is frozen, it means your air conditioner has been overworking itself trying to keep your house cool. However, as hard as it is working, your house stays hot.

This could be happening because of problems with air flow. Dirty filters and blocked duct work can be behind the issue. Or your air conditioning service may find a problem with your refrigerant or a faulty blower fan.
