How Furnaces Work
Have you ever noticed that it’s pretty much the coldest day of the year when your furnace stops working? Well it may seem that way to you, but we’re thankful that’s not really the case. We’re busy repairing and replacing furnaces throughout the cold season.
How furnaces work is pretty simple. There are two types of vents in your home. One set of vents is connected to the “intake” side of your furnace. That’s where the furnace draws air in. The air is then blown across the heated sources of your furnace, and then distributed within the ducts to all of the other vents throughout your home.
Choosing a new furnace can be an intimidating process. There are nearly 100 different brands and thousands of different models. They include budget models, mid-efficiency models, and high-efficiency models. Repairing and/or replacing a furnace is NOT a do-it-yourself job. Replacing or installing HVAC equipment will require the help of a fully qualified and licensed HVAC contractor, as they require handling high-voltage electricity, plumbing, and gas lines, and in some cases, venting combustible gases or refrigerants.
Furnaces – Things to Consider:
There’s nothing more important than proper sizing. Size matters. One of the biggest mistakes other contractors make is assuming that your previous furnace was properly sized.
How to know the proper size? There’s only one way to do it right. Load calculations – and any contractor who says “We’ll do it before we start the job” isn’t doing it. That’s why we don’t give you a proposal until all the load calcs are done.
Which fuel source? Electric, gas, propane or oil. Gas is the most popular, and oil and electric are typically the most expensive. They all have their benefits and it’s best for us to discuss all of them before you make your decision.
What type of unit should we get? High-efficiency units are typically more expensive up-front but in the long run, they cost less. Just remember – High-Efficiency may mean higher complexity.
Other factors: Manufacturers offer discounts and rebates at certain times. We’ll definitely let you know if there are any available. Some units run quieter than others. With more than 1,000 different models, we’re certain we can find a furnace that matches your budget and your requirements.
