Why Is the House Still Not Cooling After Installing a New AC Unit?

You’ve recently installed a new air conditioner or replaced your old AC unit with a new one. The system seems to be running smoothly; however, the house is still not cooling. Did we get it right? Well, you’re not alone.

Many people have experienced cooling problems replacing the old AC unit with a new one. But before you call an expert for air conditioning repair in Vaughan, it’s a good idea to get yourself familiar with the issues of why this is happening in the first place. This blog will provide information about the most common reasons why your AC unit is not cooling your house and help you overcome them.

Improper Installation

The most common reason homeowners have a problem with their air cooling units is that they are not installed correctly. Hiring unlicensed, inept contractors, who don’t have experience with air conditioners probably won’t be able to install the unit correctly. If you’re buying or installing a new unit, hire a licensed HVAC service provider to install it.

When you call our experienced, certified air conditioning contractors for installation at Martino HVAC, we will ensure that:

  • The unit is placed in a location where it receives proper airflow
  • The unit is adequately vented to the outside of the home
  • The compressor is running at full capacity
  • The unit is properly installed and wired correctly

Wrong Location

The most overlooked reason, yet the most common one, for a house to not cool down is when the AC has been installed in the wrong location or in an area that gets direct sunlight as it can cause issues with the condenser fan and other parts.

Old Ductwork

Another common mistake homeowners make when installing their new AC units is failing to hook them up correctly to their existing ductwork. The old ductwork may also be clogged with debris, which can cause your new unit to work harder than it needs to.

Make sure that you have a professional take a look at your old ductwork to ensure that it is clean and in good shape before connecting your new AC unit. This will prevent the need for air conditioning repair in Vaughan.

Clear Away Obstructions

If your AC unit is installed outdoors, make sure that there are no trees or shrubs blocking the airflow to the unit. The same goes for any indoor units; clear away any furniture or objects that might be blocking the vents.

Leaky Or Incorrect Refrigerant

The refrigerant in the air conditioner might not be compatible with your home’s HVAC equipment or could be leaking due to a leaky valve or gasket. You should check for leaks in your AC unit’s refrigerant system. If you find any leaks, you need to repair them immediately so as not to damage your system further.

Also, if your AC unit is not cooling, it could be due to the wrong refrigerant. This can lead to problems with your AC unit not functioning efficiently and even cause damage to your system. That’s why it’s important to know what type of refrigerant goes in which part of your AC unit before purchasing one. Your AC unit should have a label indicating the refrigerant used in it, but you should contact an expert to replace the refrigerant with the correct type.

Incorrectly Sized AC Unit

Another reason your AC unit is not efficiently cooling your home is that it is too small in capacity. That means it takes longer for your home to cool off when it’s cold outside because there isn’t enough air flowing through it.

The larger the unit, the more air it can move within minutes. As such, it will take a short time for your house to cool off once you turn it on. If you have a small AC unit and have turned it on for an extended period, you may need an upgrade or replacement. A newer and bigger model will have better efficiency and cooling capacity.

However, keep in mind that you can also accidentally get a unit that’s too big for your home. Contact a qualified technician to help you determine the right size unit for your home.

The Vent Is Blocked

The final reason on our list is a blocked vent. The airflow within your home is determined by how air enters and exits your home. The use of vents and registers accomplishes this. The vents will allow air to enter your home, while the registers will direct that air to where you need it most.

Unfortunately, as time goes on, these components can become clogged or obstructed, which will cause less than optimum performance from your AC system. Our licensed technicians will take care of this issue for you and spring clean your vents. Call us today to book an appointment for air conditioning maintenance in Mississauga!
