How do I know if my AC system is working properly?

A malfunctioning cooling system isn't always obvious. Sometimes the signs are quite subtle, so much so that you may want to doublecheck that your AC system is working properly. It is always a good idea to inspect your AC system on a regular basis, especially before the summer. Below are a few ways to determine if your AC is working properly:

  • Check if the temperature inside your home corresponds to the temperature set on your thermostat.
  • Check that your AC system is quiet and is not making any strange noises.
  • Check that your AC system is not leaking any fluid.
  • Cool air is blowing out of your vents without issue.

If you have said "yes" to all these, then your AC system is working properly.

What should I check if my AC system fails?

A cooling system seems to always fail on the hottest days! If you are feeling the heat and your AC system is not providing relief, there are a few things you can check. Do the following:

  • Check your drive belts, which are used to supply power to rotate the refrigerant pump.
  • Check your compressor clutch located at the front of the compressor. If it isn't turning, you may need additional refrigerant.
  • Inspect around your AC system for leaks.
  • Remove any debris in or around your system.

If you can't figure out what is going wrong, you need to call Nytech Heating and Cooling today. We can help diagnose the issue with your cooling system and repair it quickly.

What does the word "ton" mean when it comes to air conditioning?

When you hear the term "tonnage" or "ton" concerning your AC system, you may be wondering what this unit of weight has to do with keeping cool. The "tonnage" is actually a rating of your air conditioning. It measures the amount of heat that the AC unit can remove from a home within one hour. To adequately cool your home, you will need one ton of air conditioning for 400-1000 square feet. You don't want tonnage overkill, as it may cost you more on your monthly utility bill. If you have a specific question about how many tons you need, talk to your Nytech Heating and Cooling technician.

How do I know how energy efficient my unit is?

The energy efficiency of your unit will depend on the COP, or the Coefficient of Performance rating, and Energy Efficient Ratio, or EER rating. That is the amount of power inputted into a system compared to how much power is then put out by the system. The value of your COP will let you know how energy efficient your system is with a score between 2 to 4. EER is the ratio of output cooling energy to electrical input energy. You can compare the EER and COP scores of different systems to determine its energy efficiency. The scoring can get pretty complicated. If you have questions, it is best to discuss it with a licensed technician.
