What to do if AC isn't working properly?

We all know how important it is to have a properly functioning air conditioning system during those hot summer months. However, what do you do when your AC isn’t working as it should? Don’t fret; there are several things you can do to troubleshoot and resolve the issue.

Ensure that your air conditioning system is getting enough power. Check the circuit breaker or fuse box to see if any tripped breakers or blown fuses may be responsible for the problem. If you find any, reset the breaker or replace the fuse to see if it solves the issue.

Check the air filters in your AC unit. Dirty or clogged air filters can restrict airflow, and this will affect the efficiency of your system. Moreover, a lack of proper airflow can damage the fan motor or even the compressor over time. Replacing the air filters is a cheap and easy fix that you can do yourself, as long as you follow the manufacturer’s instructions.

If none of the above fixes the problem, you should call a licensed HVAC technician to inspect your air conditioning system. It may need a more intricate repair that requires a professional’s skilled touch. Don’t delay getting your AC inspected, as an unaddressed issue may cost you more money and discomfort in the long run.

If the issue persists, consider contacting an emergency service for HVAC repairs and schedule a maintenance plan to keep your cooling system running efficiently.

How do I know if my air conditioner needs repair?

If you are wondering if your air conditioner needs repair, there are a few signs you can look for. 

Air Flow

The first thing you should pay attention to is the air flow. If the air coming out of your air conditioner is weak or not blowing at all, it could be a sign that something is wrong. 

Odd Sound

Another sign of trouble with your AC is odd sounds or vibrations when it is running. Such sounds could mean that there is something stuck in the air conditioner or it is worn out and needs to be replaced.

Room Temperature

You should also pay attention to the temperature of the room. If it is not getting as cool as it should or taking longer than usual, there could be an issue with your air conditioner. 

Musty Smells

Additionally, if you notice a musty smell coming from the air conditioner, it could be a sign that there is bacteria or fungi build-up in the system.

Electricity Bill

It is also essential that you keep checking your electricity bills. If your AC is consuming more electricity than usual, it could mean it’s working harder than necessary and needs repairs. 

If you notice any of these signs, it is probably time to call in a professional to assess your air conditioner and recommend any necessary repairs.


AC Repair Services

Air conditioning is an essential part of a comfortable home or office environment- especially in hot, humid climates. However, air conditioning units are not immune to malfunction, and it can be frustrating to return home after a long, hot day to find that your AC unit is not working correctly. In such cases, it is important to enlist the services of an experienced and reputable AC repair company to help you diagnose and fix the problem.


AC repair services typically provide a range of services that can help you restore the functionality of your AC unit. These services may include routine maintenance, such as cleaning and replacing filters or fixing refrigerant leaks. They may also include more complex repairs, such as fixing compressor or motor issues.


When searching for an AC repair service, it is important to look for a company that has a solid reputation for quality and reliability. Look for a company that is licensed, insured, and experienced in working with the type of AC unit that you have. 


Additionally, make sure that the company is willing to provide a clear estimate of the costs of repairs and that they offer a warranty on their work. With the right AC repair service, you can enjoy a comfortable and functional home or office environment throughout the hottest months of the year.

Common air conditioning system repair

Here are the most common air conditioning system repair needs we see each week. Remember, if you aren’t sure what’s acting up, we will come to you, diagnose the problem, and make the repair the same day:

  • Clogged or dirty air filter
  • Dirty or imbalanced thermostat
  • Leaking refrigerant (also called Freon)
  • Clogged drain line
  • Faulty wiring
  • Corroded, dirty, or frozen coils
  • Worn contactors

Let’s look at each of these problems in a little more detail.

Clogged or Dirty Air Filters

As homeowners, the easiest DIY AC maintenance check we can and should perform is on our air filters. Depending on the specifications of our HVAC systems, we should mark our calendars to check our AC air filters every month or three months. This is an important aspect of HVAC service.


When checking the air filter of an air conditioning system, the experts at Home Comfort USA evaluate the cleanliness of the filter. An insider secret is to simply shine a flashlight through the filter. If little to no light is getting through, you can be confident the filter needs to be cleaned (if reusable) or replaced.

Dirty or Unbalanced Thermostat

The last thought to consider in the maintenance check lies within the thermostat. There are a myriad of problems that can happen with the AC unit inside that little rectangle on your wall. From the embarrassing mistakes of “is it in the right setting?” to the behind the scenes problems of an imbalanced thermostat or dust impacting the internal readings, the AC thermostat can be a head-scratcher to diagnose. 

If you experience a breakdown in the middle of summer heat, our HVAC service can provide emergency AC repair and schedule service for any necessary heating system or air conditioning installation. Home Comfort USA technicians have come across every thermostat you could think of (digital and analog), and we can have yours checked over in no time flat.

AC Refrigerant Leaks

AC refrigerant leaks can be a major issue for homeowners, especially during the hot summer months. Refrigerant is a crucial component of air conditioning system, as it is responsible for absorbing heat from the air inside your home and releasing it outside. However, over time, refrigerant can leak out of the system due to various reasons, such as corrosion, wear and tear, or manufacturing defects.

If you suspect that your air conditioning is not working as well as it should be, or if you notice any strange noises or odors coming from the system, it could be a sign that there is a refrigerant leak. Not only does a faulty air conditioning system create an uncomfortable living environment, but it can also lead to higher energy bills and potentially costly repairs.

In some cases, refrigerant leaks can be easy to fix with a simple refill of the refrigerant. However, if the leak is more severe, it may require a professional to diagnose and repair the issue. To avoid AC refrigerant leaks, it is important to schedule regular maintenance for your air conditioning system, which can help identify and address any potential issues before they turn into major problems.

Have you ever wondered what makes the air from your air conditioning system cool in the first place? The answer is simple: Freon. If you’re having issues with fluctuating temperatures, you are likely low on Freon.

This is a dangerous sign that you might have a leak, which could be anywhere from a low-cost fix to needing to replace your entire AC unit.

When it comes to air conditioning repair services and regular maintenance checks, be sure to give Home Comfort USA a call, so Freon doesn’t become a word that triggers unpleasant AC memories.




Yearly Air Conditioning Maintenance Check

An AC technician speaking to a customerThere is nothing that can replace the amazing feeling of walking into a well air-conditioned home during the summer months. On the flip side, there is nothing worse than when the air conditioner decides to call it quits in the middle of July the day before family or friends are supposed to visit. Rather than hoping your AC unit is ready for the dog days of summer, why not schedule a routine maintenance check to put your mind at rest? Scheduling regular maintenance for your HVAC system will save you from exponentially costlier repairs in the future and extend the life of your unit. Our expert technicians will go through our 32 Point AC Tune-Up and Cleaning, which includes:
