When To Replace Air Conditioner

When your air conditioner no longer pumps out cold air, there could be several reasons why. Most commonly, home and business owners opt for air conditioning replacement because their current system is broken beyond repair. This failure often comes as a result of the age of the system, lack of maintenance, or misuse. Regardless of why you need to replace your air conditioner, the HVAC technicians at Square HVAC are available 24/7 to restore your indoor comfort.

Types of Air Conditioners We Install

There are a few common air conditioning systems used in the Philadelphia area. Older homes and buildings typically do not have ductwork and often rely on ductless systems to provide consistent cooling. If ductwork is present or can be installed, central air conditioning and heat pumps can be used. Regardless of your current setup, Square HVAC can provide dependable air conditioner replacement services.

Installing the indoor evaporative heat exchanger

First, your installer will, with your help, decide on a suitable place to put the indoor unit. These must be attached to a wall and placed at least 7 feet from the floor. Additionally, A/C units must have between 6 and 12 inches of unobstructed space around them in all directions. This is to allow for sufficient airflow to and from the device.

Once this space is determined, an engineer will then fasten a mounting plate to the wall. This metal sheet will be between the unit itself and the wall to prevent any damages to either, as well as keep the unit secure.

After that, a hole will be created via circular drill near the air conditioning installation. It’s typically 3 inches in diameter, and this is done to give room for the cables to be passed through. You’ll have to check that wherever the mounting plate and hole are placed there are no pipes behind them.

A quick check is given to the internal electrics of the unit before the cables are piped through the hole and out to wherever the external unit will be. The unit itself is then fully fastened to the mounting plate.

Installing the outdoor condensing unit

Much in the same vein as installing the indoor unit, the outdoor condenser must be positioned at least 12 inches away from a wall. It also, of course, must be installed near the hole that was drilled earlier. Additionally, whoever installs the unit will have to ensure it is not within 10 feet of a television or an antenna.

A concrete pad is placed on the ground to form a foundation for the unit. Natural ground can move and shift over time, so laying something firm is key. Oftentimes these will be raised too – to prevent any puddles from rain forming underneath the condenser.

Then comes the physical placement of the unit. The outdoor heat exchanger is fastened to the concrete using rubber pads or cushions. These will not only keep it in place, they will also reduce the vibrations of the machine.

Finally, the internal wiring is inspected before the cable that were run through the wall are connected with the external machine.

Final touches

A few last-minute checks and assurances are then made to the set-up to ensure its functionality and efficiency.

Professional installers will, at this point, bleed any humidity and air from the unit. This is usually found in the refrigerant section of the machine. If they don’t then the air conditioning installation will not operate properly and will feed in the wrong temperature of air to your home.

Any loose cabling is then covered in piping. This not only provides added protection from damage and rainwater, but also tidies everything up. Air conditioning installations might not be designed to be the most visually appealing. But small touches like these can at least make them look well cared for and professionally put together.

The very final step is for the installer to turn on the machine and check it’s working. If everything has been done correctly, your rooms should feel the sudden influx of cool air.


For optimal performance air conditioners need to be serviced every year to ensure proper operation & efficiency. An AC tune up will include cleaning condenser coils, testing the refrigerant levels, inspecting the indoor blower motor & wheel & checking for leaks & debris. Neglecting annual maintenance could result in decreased performance & efficiency & can also lead to pricey repairs.


Split system air conditioners, or ductless systems allows you to create a comfortable indoor environment in spaces where adding ductwork might be impractical, inefficient or too expensive. High-quality, low cost wall-mounted units provide zoned comfort solutions. Split systems are the perfect solution for sun rooms, hot or cold rooms, media rooms, lofts, garages, basements, bonus rooms, offices, additions & any older homes without existing ductwork. Ductless heat pump systems pump cooled or heated refrigerant directly to air-handling units through small pipes. Each living space has its own air handling unit, and each unit has its own wireless electronic temperature controller.


It’s important to receive a quote from a professional, licensed HVAC Contractor to ensure proper & accurate measurements can be used to calculate the proper size AC Unit to install. It’s also best to consider how long you will be staying in your home. If you have no plans on moving in the near future you should make the initial investment on a high efficient AC unit so that you will benefit from the energy savings on a monthly basis. If you do not plan on staying in your home, or are trying to sell your house in the near future, you may want to go the less expensive route & go with a basic model since you will not be receiving the benefits of the initial investment of energy savings on a monthly basis.

Make sure to purchase a quality name brand like Trane products to allow peace & comfort knowing your AC has undergone rigorous testing & guarantees high quality performance & reliability. Installing a high end brand ensures you will not experience your unit breaking down or requiring expensive repairs in the near future. Going with a higher end brand also comes with great warranties from the manufacturer so in the event your unit does require a repair, your manufacturer will cover the parts warranty.
