After years (or even decades) of use, you finally decided to replace your old furnace with a new one. However, your brand-new, modern furnace is still susceptible to the same problems as your old furnace. Follow these tips to ensure that your new furnace from a site like http://robertbair.com continues to operate as well as it does right now:
Resize Your Air Ducts
Unless your replacement furnace has the same specifications as your old furnace, it's likely that your existing air ducts are no longer suitable for your new furnace.
Upon installation, your air ducts are sized according to the airflow and heating capabilities of your furnace. When your air ducts perfectly match the performance of your furnace, they'll allow for sufficient airflow speed and ventilation. However, if your air ducts are too small or too large for your new furnace, then they'll either restrict airflow throughout your heating system or fail to quickly ventilate the heat produced by your new furnace. In either instance of improperly sized ducts, your furnace won't be able to generate the number of BTU's (British thermal units) listed in its specifications.
However, resizing the system of ducts throughout your home is no easy task. In addition to extensive physical labor, you must also wear protective clothing and a respirator to avoid inhaling contaminants such as mold or asbestos that may exist inside your home. Instead of attempting to perform this job by yourself, hire an HVAC technician to do it for you.
Keep Your Furnace Clean
Forced-air furnaces, whether gas or electric, will develop several problems when their components are coated in debris. For example, your furnace's blower motor uses a fan wheel with dozens of thin blades to generate airflow. When your wheel spins, its blades pull air into your furnace. However, when the blades are coated in a thick layer of dust, dirt, or pet hair, the amount of air that flows between them will be significantly reduced.
However, your blower motor isn't the only component that must be kept clean. Your combustion chamber, air filter, and burner tubes should be cleaned prior to any period of excessive use to avoid airflow restrictions or an increased risk of a furnace fire.
Although your blower motor, fan wheel, and burners should only be cleaned by a professional HVAC technician, you can replace your air filter and clean your combustion chamber by yourself.
Replacing Your Air Filter
A conventional furnace filter is located between the return duct and blower motor and requires replacement every one to three months depending on indoor air quality and usage hours. To replace a conventional filter, shut off your furnace, open the access panel on your blower compartment, and pull your filter out from the side of the compartment connected to your return duct. Clean away any loose debris with a rag and slide in a replacement filter.
An electrostatic filter can be cleaned instead of replaced. To clean an electrostatic filter, shut off the power to your electrostatic system and open the door on the front of the unit. Pull out the large, square-shaped cells and the wire prefilters. Wash the cells and prefilters in a mild mixture of soap and warm water. If necessary, blast the prefilters with a garden hose to remove stubborn debris. Reinstall these components into your electrostatic system once they're dry.
Combustion Chamber Cleaning
Shut off the power and gas to your furnace and let it cool. Open the door on your furnace and use a water-dampened cloth to wipe away debris from the sides and base of the chamber. Collect the lint and absorb the moisture left behind by your rag with a microfiber cloth before closing your furnace and restoring the gas and power supply.
Never use a chemical agent to clean your combustion chamber. Even the mildest household cleaners will leave behind a residue that can be both flammable and toxic.
Although your furnace may seem like it's operating efficiently even after a few weeks of use, it's possible that it already requires a filter replacement or cleaning. If you don't have the time or means to clean your furnace regularly, then contact a professional HVAC technician to perform your furnace maintenance for you. Although hiring a professional may be expensive, doing so will keep your heating costs throughout the year as low as possible.
