Ask the Heating and Cooling Expert – Jason Rogers
Hello and welcome to our continued readers and new readers alike. This month`s question has been a well asked one at any trade show or just in general “When should we replace our furnace?” That seemingly simple question actually has many different parts that we will break down in this article. Let’s get started.
The first part we will address is what time of year is more conducive to replace your furnace? We try to book installs for furnace replacements during the milder times of the year, weather wise. The reason for this is that during the installation process we have to make holes in the exterior finish of a home, some of the exterior products like siding become very brittle when temperatures travel below -25°C and may split or crack. Also the cold weather brings more snow & ice that can make it very hazardous to go on customers roofs to install a chimney liner. Rest assured that we take all safety precautions necessary to work on the roof and always protect customers’ homes against damage.
Next we will address how old should a furnace be before you replace it? Here is a good rule of thumb; if your furnace is original and your home was built pre 2007 then the furnace could be between 75%-80% efficient. If you are the type of person that wants to save on your energy bills then you may look at upgrading your furnace to a 95%-98% high efficient ultra-quiet unit, that’s a projected savings of 20%-23% on your heating costs. If your home was built pre 1995 then your insurance company may ask you for a letter that says you have had a certified heating contractor look at the furnace and it is in good working order and they have to perform a carbon monoxide test. You may be asked to have this test done yearly at a cost ranging from $90.00-$150.00 per time and with the cost of energy going up the last thing you want to do is tack on another cost to keep the old furnace. We also recommend that if your furnace repair bill is going to cost more than 30% of a new one then it is always a better bet to replace the furnace.
I hope this guideline helps and we would be happy to answer any questions you may have! Call us at 403-358-3730.
