We are taking the following precautions due to the COVID-19 virus. All of our technicians have masks, glasses, latex gloves and shoe booties if they have to enter your home. Our technicians also have hand sanitizer and disinfectants that they use after every call.
If we are there to do maintenance and we don’t have to come inside your home to get to the equipment, we are asking homeowners to adjust the thermostat for us so we can do the system maintenance without entering the home. We will not be shaking hands and will keep our distance from customers.
You need to know how your contractor selected the correct size furnace for your space. If the furnace is too big, it will short cycle leading to a number of issues, including uncomfortable temperature swings, a greater chance of condensate collecting and corroding furnace components, and excessive air flow out of registers.
Your contractor should be experienced in installing the exact model of condensing gas furnace you purchased. Ask about previous installations, and ask to see pictures. A professional job will look as good as the manufacturer’s brochure pictures (no odd attachments, no out-of-level ducts and pipes, and no hanging wires).
Ask for a reference from previous installation customers. Call them and ask if they were pleased with the service, and how the contractor handled callbacks for minor (or major) problems.
Finessing the Furnace
Footing matters. Your new furnace should sit on a raised bed of concrete or brick, so any potential basement flooding does not harm the unit.
Location matters. The condensing gas furnace needs outside air for maximum efficiency, so the air intake pipe should be a direct run. Next to it you should find the exhaust pipe, angled up to the outside so any condensate will drip back into the furnace. The two pipes need to be similarly situated outside your home, so wind pressure across their openings is equal (preventing back drafting).
Details matter. The drainage for a condensing gas furnace needs to be close to the furnace, with a drain tube running without bends or kinks directly into the drain. Ideally, the furnace itself will tip very slightly toward the drain to aid in runoff of condensate. All electrical connections should be grounded.
