Some important questions to ask about heating and cooling, including how air conditioners and furnaces are rated for efficiency.

Q: What is an air conditioner SEER rating?

A: Air conditioners are given a SEER (seasonal energy efficiency rating) based on electrical usage. A higher rating means the air conditioner will be less expensive to operate. For example, a 13 seer unit will cost half as much to run as a 6 seer unit. Although this rating is important, other factors are equally important when choosing an air conditioner. The type of compressor and warranty should be strongly considered. As with any equipment purchase, installation is also critical. Installed properly, there should be very few problems. Done incorrectly, it could be very expensive and void your warranty.

Q: Can you explain how a 2-stage, variable speed furnace works?

A: A 2-stage furnace has a variable speed, DC blower motor that is 75% less expensive to run than a conventional motor. This furnace operates on low-fire, burning less fuel 90% of the time. When higher heat is needed, high-fire will provide heat quickly, using all of the available gas. Coupled with a blower that circulates air continuously on low speed, this kind of furnace will keep the air temperature even throughout your home, control humidity and filter air 24 hours a day. This is the best type of climate control available.

Q: What is balancing a home heating and cooling system, and why is it so important?

A: Balancing, or adjusting air circulation in your home will help eliminate cold and hot spots that can be uncomfortable. This is done with a velometer, which measures air velocity and temperature. It should be done in all homes, new or old. It will reduce operating costs and increase the comfort level in your home.

Q: How important is changing my furnace filter?

A: It is very important. When a filter becomes full or clogged, it dramatically reduces air flow through the furnace. This can cause many problems. In the heating season, it often causes the furnace to overheat and shut down, dropping the temperature in your home, prompting a service call. In the cooling season, it will cause the air conditioner to run longer, and eventually freeze up and shut down. Either of these problems can cause further damage to the parts in your furnace or air conditioner. Changing your filter regularly will help protect your equipment and keep service calls to a minimum.

Q: How regularly should maintenance be carried out on my furnace or air conditioner?

A: Regular maintenance has many benefits. Having your equipment serviced regularly will improve efficiency and keep service calls to a minimum. Most companies have maintenance plans that allow technicians to monitor your equipment and foresee problems before they become costly or dangerous. These plans offer the homeowner reduced service costs because we visit regularly, becoming more familiar with your home, equipment and family. Many pre-schedule maintenance dates 3 times a year to make it a worry-free experience.

Q: What kind of rebates are available to the Ontario homeowner?
