What Are Common AC Issues?
While numerous things can go wrong with an AC unit, some are more common than others. For instance:
  • A faulty thermostat. In this case, it is crucial to check that it's working and set to the desired temperature.
  • Loud noises. There are several possible causes for this. But often, screeching or squealing sounds point to a motor bearing problem or a faulty internal belt.
  • An AC that is running but isn’t cooling. Unfortunately, this common problem has several potential causes. It could be a dirty air filter, a blocked condensate drain, or a low refrigerant level.
  • A malfunctioning compressor. This could indicate a burned wire, a defective start capacitor, or simply a damaged compressor.
When Should I Choose AC Repair vs. Replacement?
When determining repair vs. replacement, there are plenty of considerations. Our technicians will consider both sides of the question. Here’s how to tell that you should repair rather than replace your AC:
  • You have a new or relatively new system
  • The cost of repair vs. replacement is less than 50% of the unit’s value, and it doesn’t require frequent service calls
  • You’re planning on moving in the immediate future (talk to your real estate agent to determine whether repair or replacement would be in your best interest).
  • If your system is neither too old or new, some simple maintenance may be all it needs to prolong its useful life.
Signs It May Be Time to Replace Your Unit Include:
  • Your system is too old
  • Frequent breakdowns
  • Your unit is excessively noisy or turns off randomly
  • Uneven temperatures
What Are the Advantages and Disadvantages of Installing a Ductless Mini-Split System?
If you’re considering adding a ductless mini-split system to a new construction or home renovation project, consider the following advantages and disadvantages. Advantages
  • Flexibility
  • Better heating of rooms
  • Ease of installation
  • Customization
  • Energy efficiency
Disadvantages
  • They require proper placement. Improper placement can lead to short cycling
  • Many property owners find the look of air handlers visually unappealing
  • Initial installation costs can be expensive
  • Sometimes it takes more than a mini-split to solve the heating and cooling needs of a space.
What Should I Consider When Buying a New AC?
A good air conditioner offers more than respite from the summer heat. It also gives you the benefit of humidity control and air purification all year round. With countless options flooding the market, knowing how to select the proper AC for your property will help you make the most of your unit. Some of the most critical factors to consider include the unit’s energy efficiency, cooling capacity, zoning, budget, warranties, installation, and maintenance requirements.

What Do You Check During AC Maintenance?
Maintenance service ensures your unit isn’t suffering from any repair issues and will keep your AC working at peak efficiency. Typical tasks performed during AC maintenance include:
  • Checking the thermostat to ensure it’s working properly
  • Changing or cleaning the air filter
  • Checking system controls (is the system starting, operating, and shutting off properly?)
  • Checking/tightening electrical connections
  • Lubricating moving parts
  • Checking and clearing the condensate drain line
What Is a Good AC Temperature Setting?
The U.S. Department of Energy recommends setting your thermostat to 78F when you’re indoors. Setting your thermostat to this level will keep you cool without an unusually high cooling bill. If you still feel like lowering the thermostat setting, consider investing in a dehumidifier and implement some tips to maximize cooling efforts in your home. For instance, you can limit the use of heat-generating appliances and install window treatments that prevent heat from entering through your windows.
What Is SEER?
All air conditioners have a SEER (Seasonal Energy Efficiency Rating). A higher SEER means a unit is more energy efficient. It reflects the overall efficiency of a cooling system on a seasonal basis. The SEER rating of a cooling system also ensures the system is safe, productive, and environmentally friendly. Although the initial cost of an AC with a higher SEER rating may be higher, the lower operating costs will save you money in the long run.
