5 Things To Consider When Buying A Central Air Conditioner

1) Size of your air conditioner.

A) If the air conditioner in your home is too small it will constantly work.

It will never get to the temperature you set on your thermostat and will not shut down.

B) If the air conditioner in your home is too big, it will not work long enough to remove the moisture from your home. This will result in you having a very cold and uncomfortable home. This is due to moisture still in the air and every thing will feel very sticky.

Please note:The Rule of Thumb for your home is that each ton of cooling is good for 1000 square feet in a regular home.

For example: A two ton Air conditioner is good for up to 2000 square feet in a regular home.

 

The rule of thumb is not always right. A proper heat gain calculation will determine what size of an air conditioner you will  need. items like big windows and sky lights can drastically increase the size of the air conditioner you need.

A higher SEER rating provides greater energy efficiency. The minimum standard SEER for air conditioners is 13, though most modern air conditioners have a SEER that ranges from 13 to 21.

 It is recommended that 13 to 16 seer air conditioners are the most reasonable to buy in Ontario.

2) Choose the right contractor to install your air conditioner.

Did you know that nine times out of ten the installation itself will determine how well your central air conditioner runs? Stated like that it might sound obvious but if you buy the best unit on the market and it is not installed well a less expensive brand may be working superior.

If your air conditioner is installed by a licensed professional, most likely you will not have a problem with your air conditioner for several years. But if it is not installed right you are going to have lots of problems.

The most important factor is to hire a licensed and experienced contractor. Not only that, you should make sure your contractor will follow the following guide lines:

1) Have right tools and materials to install your ac. Like gauges, refrigerant recovery machine, Vacuum pump, proper welding tools. Copper pipe, Insulation, Etc.

2) The contractor will take apart and remove the existing air conditioner.(if you have one)

3) The contractor will install new duct systems or perform duct repairs.

4) Preparing the installation site. This may involve setting a concrete pad outside to support the air conditioner or installing rooftop supports for a packaged system installation.

5) Your new outdoor unit will be positioned correctly. The contractor will install it and secure it to the site.

6) If you are also replacing your air handler, install the indoor unit. While it’s a smart idea to replace both indoor and outdoor units at the same time, in some cases you may elect not to replace the air handler when you have a new outdoor unit installed.

7) Connecting the indoor and outdoor units. The contractor will determine the appropriate size for refrigerant lines, drain piping, and electrical lines. Some of these components link the parts of the split system.

8) Connecting the thermostat to the central air conditioner. You may have a new thermostat installed or continue to use your existing unit.

9) The vacuum will be pulled to remove contaminants from the refrigerant lines and charge the new central air conditioner with refrigerant.

10) The new cooling system will start and run.

11) The contractor will perform an installation inspection to ensure the installation was done correctly and the system functions properly.

3) Air conditioner warranties.

Air conditioner warranties vary by manufacturer. The best central air conditioner warranty available today is a lifetime limited warranty for certain system components. For most manufacturers, a 10-year limited warranty is a popular warranty term.

Your new air conditioner’s warranty can save you a great deal of money down the road, should covered components malfunction and fail due to a manufacturing defect. Air conditioning systems typically last 15 to 20 years, so a longer warranty term is effective for a significant portion of the system’s expected service life. If your system’s defect is covered by warranty, the cost of the new component will be covered, but you may have to pay for the labor service cost.

Some manufacturers offer the option to purchase extended warranties that add a certain amount of time to the original manufacturer’s warranty. This purchase is not required, but you may consider adding an extended warranty for additional coverage and peace of mind throughout the years you’ll use your cooling system.

Your HVAC installer may offer a warranty covering installation and labor. Where manufacturer’s warranties only cover specific components that malfunction under certain conditions, your contractor’s warranty can cover system issues arising due to faulty installation, repairs, or maintenance.

4) Location where your Air Conditioner will be installed

While the indoor portion of your air conditioner is responsible for removing heat from your home’s air, its job would be useless without the outdoor Condenser. That’s because the condenser unit takes the heat that was removed from your home and actually expels it to the air outside. Without the condenser unit, the heat from your home would have nowhere to go!

 

If your condenser unit is not placed properly, it will not be able to do its job effectively. That means that your air conditioner will not be able to adequately cool down your home’s air, which will make your home uncomfortable, raise your energy bills and increase the likelihood of your system stop working.

5) Maintenance Tips

  • To make sure you get the most out of your air conditioner system, check and replace your filters monthly in summer months, and clean or change them when dirty. Clogged, dirty filters block normal airflow and can reduce a system’s efficiency.

  • Like dirty filters, dirty indoor and outdoor coils reduce airflow through the system. This reduction can decrease system efficiency and lead to compressor damage. Outdoor coils should be vacuumed or brushed clean to keep it free of dirt and leaves. Then it can be carefully cleaned with a garden hose.

  • Indoors, be sure that vents are not blocked by furniture, carpets, or other items that hinder airflow. Inadequate airflow can lead to compressor damage.

Balance comfort with energy and cost savings – reduce the impact of air conditioning on your energy bill by using a programmable thermostat and maintaining it properly. Find out more ways you can save energy in your home all year round.
