Air Conditioner Buying Guide: How to Buy Air Conditioning for Your Home

buying a new air conditioner sudbury

If you’re considering installing or replacing your central air conditioner in your home, you want to make sure it is the best option for you and your family. HVAC (heating, ventilation and air conditioning) is key to a comfortable home and is one of the biggest investments you make for your home.

Buying an air conditioner is one of the most significant home improvements to make your home more comfortable. During hot, humid summers, an air conditioning system can be the one thing between you and a great sleep.

Determine what type of air conditioner you need

A central air conditioner distributes conditioned air throughout the house, whereas a window or portable air conditioners cool one room only. If your home does not have ductwork, a ductless split provides cooling for your home. A heat pump is similar to an air conditioner because it can cool your home in the summer and can be reversed in winter to heat your home.air conditioner installation sudbury area 669 heat

  • Central air- whole home cooling
  • Window or portable air conditioner- one room cooling
  • Ductless split- air conditioner for homes without duct work

Components of a central air system

A central air conditioning system consists of a condenser unit, an air-handling unit with a blower (forced-air furnace) and an evaporator coil. Your ductwork system is used for exchanging room air with chilled air.

The condenser is usually placed outdoors, and the air handler with the evaporator is usually placed in the basement, attic, or garage. Your ductwork is designed to go through the basement or attic and walls throughout the house.


The efficiency of your air conditioner is an air conditioner’s ability to convert energy into cooling in the most cost-effective way. The more efficient unit means more savings for you.

SEER ratings (Seasonal Energy Efficiency Rating) is given to every AC unit and it’s important to look. The higher the SEER rating, the more efficient the unit and the less it will cost to provide cooling. Air conditioners manufactured today must have a SEER rating of at least 13, but the most efficient models have SEER ratings of 15 or 17.

Warranty matters

When you buy any HVAC system, the warranty is important.  The warranty of your air conditioner is key to making sure you are covered for some of the cost of parts and labour (depending on the warranty).

Ask your sales advisor what warranty comes with the unit. Maybe more established air conditioning contractors will even offer an extended warranty option, so that is another thing to ask if you don’t like the warranty option provided. Warranties defer on each unit and brand of a/c’s.

Air conditioner repair or replacement: things to consider

If you currently have an older a/c unit and are considering repairing it, you might want to think about the cost of repair versus the cost of replacing it. With summer comes a frequently asked question “Should I fix or replace my air conditioner?” Here are 3 things to look for when you are considering replacing your cooling system.

Here are 3 things to look for when you are considering replacing your cooling system.

1. The age of the air conditioner– air conditioners are manufactured more efficient than previous years, which saves you money.
2. Money spent on costly air conditioner repairs– does it make sense to put $1,000 into an old unit when you can replace it for a low monthly payment? Consider all your options. If you are moving soon, it might not make sense to buy a new unit.
3. Your energy bills are increasing– this is a huge factor. Take a look at your previous bills and see if they skyrocket in the summer.
