"I recently got estimates from a half-dozen HVAC companies for the installation of a full ducted heat-pump system into an home that did not have it - a retrofit. Though I ultimately chose a different company for the project, AireServ really impressed me with the quality of their proposal. I submitted a request on their website and they called me about one minute later. They came out the next morning. They were good listeners and the system they recommended was exactly what I wanted (in contrast to several competitors). They evaluated my house thoroughly, looking at all aspects of exactly how the system would be installed, as well as sizing the system properly with all factors considered. The price they quoted me was not the lowest, but it was far from being the highest. If you are considering a project, I recommend at least getting a bid from these guys."

Energy Efficiency Auditing FAQs, answered by experts

Some types of electric fireplaces use more electricity than others. Models that produce 1,500 watts will have more of an effect on your heating bill than 750-watt models. 

Electric fireplaces use an average of $1.85 of electricity every eight hours. These minimal operational costs aren’t likely to make a big difference in your electric bill—unless you’re using it as a primary heating source for your home and it’s running most of the time.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.
