Heating Emergency or Scheduled Upgrade – 5 Things to Expect from Your HVAC Comapny

Wednesday, December 3rd, 2014


Recently my Facebook feed has been full of posts beginning “We woke up to a 50 degree (or thereabouts) house! What a time to be left in the lurch!” Murphy’s law says that many families will experience heating problems on the coldest days of the year. However unfair this may seem, I’ve found myself commenting that not all HVAC companies are created equal! Here are a few things to look for and a few services I’ve come to expect (It’s okay to expect the best!):

  1. 24/7 Emergency Service
    Any time of the day or night, the service crew should be ready to help. A large number of trained technicians on staff is key, so your wait time is minimized. One motto: “Your emergency is our emergency,” is a comforting idea when your family is cold and time is of the essence! And just in case you’re in the midst of one such emergency, Here’s a heating company who happens to fit all the criteria in this blog post.
  2. 100% Satisfaction Guarantee
    There’s not much more to say about this one, except that this is a rare thing for a company to commit to, and those who have are elevated to a separate level of business in my mind. It makes me think of other stand-outs like Costco, Nordstrom, and REI, who have similar policies. I feel so confident buying from these places, because if something goes wrong: They will fix it. Period. Customer satisfaction is THE core of everything they do.
  3. Building Performance Certified
    These nationally certified staff are trained to take the health, efficiency, and comfort of the entire home into account. Only one local company has much of their team go through this rigorous training and testing to earn their titles as BPI Certified Professionals. BPI is the Building Performance Institute. They “develop standards for energy efficiency retrofit work using an open, transparent, consensus-based process built on sound building science….and quality assurance services that help raise the bar in home performance contracting.” Read more about BPI, and check out their Guide for Homeowners on how it all works and how to find the best contractor for your needs.
  4. Lifetime Guarantee and 1 Year Warranty
    Although these might sound like oxy-morons, they actually apply to different areas of the HVAC experience. The Lifetime guarantee refers to the Workmanship on installed ductwork, sheet metal, and piping. The 1 year warranty (for parts and labor) is in addition to any manufacturer warranties. The company should come out after the first year of use (free of charge) to make sure everything is working as it was when the equipment was installed. YES, this can happen with the right company. These safety nets and guarantees are some of the best and most comprehensive in the industry.
  5. Official Designations from the Manufacturer
    Look for certifications. Some heating companies will have their awards, designations, certifications, etc., on their website. These matter. One example: Carrier has a very selective process to designate Factory Authorized Dealers. They use these criteria: the job is done Expertly, Efficiently, Professionally, Right Technically, with the Right Parts, and Right for the Environment. Not all companies meet these standards. Just one more safety net to look for!

I hope explaining these 5 areas of service has given you insight on your search for a new heating system, repair, or upgrade. Now, if you or your neighbor are cold, you know what to do!

Decoding Furnace Efficiencies

Thursday, August 22nd, 2013

A forced air furnace or boiler’s efficiency is measured by annual fuel utilization efficiency (AFUE). The Federal Trade Commission requires new furnaces or boilers to display their AFUE so consumers can compare heating efficiencies of various models. AFUE is a measure of how efficient the appliance is in the energy in its fuel over the course of a typical year.

Specifically, AFUE is the ratio of heat output of the furnace or boiler compared to the total energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere. AFUE doesn’t include the heat losses of the duct system or piping, which can be as much as 35% of the energy for output of the furnace when ducts are located in the attic.

An all-electric furnace or boiler has no flue loss through a chimney. The AFUE rating for an all-electric furnace or boiler is between 95% and 100%. The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice. If you are interested in electric heating, consider installing a heat pump system.

The minimum allowed AFUE rating for a non-condensing fossil-fueled, warm-air furnace is 78%; the minimum rating for a fossil-fueled boiler is 80%; and the minimum rating for a gas-fueled steam boiler is 75%. A condensing furnace or boiler condenses the water vapor produced in the combustion process and uses the heat from this condensation. The AFUE rating for a condensing unit can be much higher (by more than 10 percentage points) than a non-condensing furnace. Although condensing units cost more than non-condensing units, the condensing unit can save you money in fuel costs over the 15- to 20-year life of the unit, and is a particularly wise investment in cold climates.

You can identify and compare a system’s efficiency by not only its AFUE but also by its equipment features, listed below.

Old, low-efficiency heating systems:

  • Natural draft that creates a flow of combustion gases
  • Continuous pilot light
  • Heavy heat exchanger
  • 68%–72% AFUE

Mid-efficiency heating systems:

  • Exhaust fan controls the flow of combustion air and combustion gases more precisely
  • Electronic ignition (no pilot light)
  • Compact size and lighter weight to reduce cycling losses
  • Small-diameter flue pipe
  • 80%–83% AFUE

High-efficiency heating systems:

  • Condensing flue gases in a second heat exchanger for extra efficiency
  • Sealed combustion
  • 90%–97% AFUE
