If you live in Loveland, Colorado, you know that it is critical to have an HVAC system that functions properly all year round. The winters can be very cold, which calls for an efficient heating system. During spring and summer, you need an air conditioning system that won’t fail you in times of need. With constant use of your AC units, you’ll find it crucial to know where to look for the best contractor for AC repair in Loveland, CO.

Of course, calling in experts every time something happens to your air conditioning unit can be expensive. Though there will be times when you need to call in a professional, you should also be able to handle the small and minor issues to save on costly repair fees. In this article, we will give you tips on how to solve the most common air conditioning problems that you will encounter.

AC Unit Is Not Cooling Enough

An air conditioning system that lacks cool air can be a sign of a problem. If your AC is perfectly fitted to the size of your room, it should be able to cool the area effectively. There are various reasons your unit will fail to circulate enough cool air. One reason is a clogged or dirty air filter. This is easy enough to solve; simply clean the air filter or replace it if it’s too worn.

A low refrigerant level can also be the cause of the lack of cool air from your AC unit. The refrigerant helps cool the air being circulated by your air conditioning unit. If the refrigerant level is low, your AC will have difficulty cooling the air. If that is the case, you can contact an air conditioning technician to refill the refrigerant for you.

When the thermostat malfunctions, start by checking if the batteries need replacement. You may also need to contact a technician if the thermostat remains faulty after basic checks and battery replacements.

AC Has Weak Airflow

It’s annoying when your air conditioning system’s airflow suddenly weakens. The AC unit is unable to cool the room comfortably, and the system struggles, which could result in higher electrical bills. This happens for several reasons, including clogged air filters, blocked air ducts, or insufficient power to the blower.

The air filters should be easy enough to clean. You can use your home vacuum cleaner for this. If you suspect blocked vents, start by clearing the area around them. For better airflow, remove rugs, furniture, or anything that obstructs the vents. Blower problems can be caused by dust on the fan blades or a bad blower motor. Clean the fan blades or change the blower motor to resolve the issue.

There Are Unusual Noises

Your air conditioning unit is designed to function with low-level noise. If you notice that your AC is making loud, sudden, and unusual noises, there might be a problem with it. If you hear rattling or buzzing noises, there might be loose parts or degrees inside the unit. A professional technician can disassemble the unit and check for the culprit.


Worn-out bearings or compressors produce whistling or grinding noises. This also requires a professional because replacing the components is not DIY-friendly.

AC Is Leaking Water

Some possible causes of the air conditioning unit leaking water include a clogged drain line, full drain pan, and damaged drain line or pan. Some AC units allow you to access the drain line so you can remove any blockages. Make sure to consult the product manual for the proper way of cleaning the condensate drain line. The same applies when you locate and empty a full drain pan. Of course, professional help is needed to repair a damaged drain line or pan.

Electrical Issues

While most air conditioning issues are mechanical, there are some cases where electrical issues cause your AC to malfunction. Issues like damaged wires, incorrect voltages, and faulty circuit boards can all cause the air conditioning system to stop working.


For tripped circuit breakers, you can resolve the issue by resetting them. However, a breaker that trips repeatedly might need to get checked by a professional electrician. If the problem involves exposed wires or voltage issues, do not attempt to DIY it if you have no electrical knowledge.

Always remember that safety must come first for any DIY fixes you are attempting with your AC units. Turn the unit off before opening it or checking the issue. Keep in mind that hiring a qualified technician is your best option if you are not confident about touching any parts of your unit.
