"For the last two years, I have signed a yearly contract with Sweetlands to do a twice-a-year check on my heating and air-conditioning service as well as On-Demand Gas Water Heater.....fall check before I use my heating system and spring check before I use my AC system. Each time, the service associate has been on time, courteous, friendly and very knowledgeable when answering any questions I may have. I've even had Judy show up to perform the bi-annual check once! As I mentioned previously, I had a bad experience with another company that led to me switching to Sweetlands. On the first check done with Sweetlands, the service representative found a flaw in the previous company's work that could have resulted in a dangerous event and was definitely costing me more money from an operational standpoint. So, the switch to Sweetlands literally paid for itself with my first visit! I definitely believe that Sweetlands is a great local business, and I intend to continue my association with them in the coming years. My annual maintenance contract covering twice yearly cleaning, maintenance and check of all three of my units (Heating, AC, and On-Demand Gas Water Heater) is $374/year."

"Outstanding, very happy with overall product. Final product is very neat and clean, and will improve overall quality and value of my house. Initially provided quote requiring no down payment. Quote was $2K less than similar company, whose quote did not include the structural repairs. Policy changed requiring 30% down payment at contract signing, but honored initial quote of no down payment. Honored $300 coupon. Agreed to more powerful dehumidifier than quote to ensure adequate coverage per manufacturers recommendation. Installed girder entire length of house at no extra cost, though quote was for slightly over half the house. When drywall cracked after jacking, had painter respond next day to patch and paint. Collaborative final inspection. Had worker come back after inspection to tape minor rips in moisture barrier, and left extra tape. Took split payment, check and credit card. Cleaned up every day, had access to crawl space daily normally without requiring access to house. Trustworthy. Feel like they will be responsive if there are any issues in future."

"Gave the quality rating based on what I've been told and seen but they haven't done my work yet. Also doing windows & facia and soffit work plus roof vents. As we've been looking at some things we had considered, we've reviewed some of our options. Their willingness to help us do and get the best job possible done, allowed us to expand our agreement. We are now going to do another project and are working on referring Rick to some of our contacts who have work."

Energy Efficiency Auditing FAQs, answered by experts

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.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

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.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.
