How to Install a New Furnace
When preparing to install a furnace, the first thing you need to do is find the right contractor. After that, you'll need to decide what brand you want to buy and the features that suit you. Most contractors endorse certain brands based on their experience. They may also pass on manufacturers' incentives to you. Since experienced contractors know furnace brands very well, it's best to find a quality contractor.
What To Expect From A Contractor
You should ask for estimates from at least three contractors who can visit your home to take a look at your existing system and inspect your insulation and vent condition. Ductwork is vital in a good furnace installation, so your contractor must be familiar with it. You should choose a contractor who belongs to the Better Business Bureau and has NATE (North American Technician Excellence) certification.
When you shop for your furnace brand, you will find that manufacturers recommend reliable dealers who can send an experienced contractor to install your furnace. These contractors would be selected based on certain criteria and would have received specific training from the manufacturer. Your contractor must have the right licenses and liability insurances. He or she must be knowledgeable about state and local building codes and able to procure the relevant permits for you before installing your furnace. Many states require that a government inspector check the work after it is done.
Getting The Right Furnace
First you'll need to determine the amount of BTUs or British Thermal Units that your home will need. This will depend on your home's size and its condition, and the general climactic conditions where you live. The BTUs you require will determine what size furnace you need. Your furnace shouldn't be undersized since you will not get proper heat. If your furnace is too big, you'll spend more on initial costs and fuel. You'll also get lower energy efficiency. If you have upgraded your insulation and windows recently, you might be able to spend less on installing a new furnace.
Your contractor can advise you on whether energy upgrades and insulation will make it possible for you to get a smaller furnace. Most furnaces should carry a 25-year warranty and can function efficiently for that period.
Installing The Furnace
Installing your furnace is not a do-it-yourself project. Even new homebuyers should consult with an HVAC (Heating Ventilation and Air conditioning) expert to size up/inspect their heating and cooling equipment. It is essential to have the actual installation done by a certified heating and cooling contractor. While you can buy your furnace directly from an HVAC retailer, the manufacturer may not support the warranty if you buy the equipment online. They prefer that you buy the equipment from their licensed distributor and get it installed by a licensed contractor. If you attempt to install your furnace yourself, you may not get the help you need if you have problems during the warranty period. You might also end up paying extra for repairs.
