Attic Fans Are Helpful in Winter Too

Monday, January 16th, 2017

Attic fans, especially solar attic fans, are excellent ways to improve a home’s energy efficiency during the summer. That’s why we often recommend people have them installed. These fans are designed to vent out the accumulation of heated air in the attic during a summer day (the radiant energy from the sun on the roof can elevate temperatures in the attic up to 130°F) so this excess heat doesn’t seep down into the rest of the house.

But you may not know that attic fans are helpful in winter as well—just as much help as they are in the summer.

Should I Get Air Filters or Air Purifiers to Improve Air Quality?

Monday, January 9th, 2017

If you have concerns about the quality of the air in your home, you’re probably not worrying over nothing. Low air quality is common throughout homes in the U.S. because the modern residential building is designed to be so energy efficient that it doesn’t “breath” well. For instance, too many contaminants are allowed to build up indoors. This includes dust, dander, pollen, dust mites, volatile organic compounds, bacteria, mold spores, chemicals, smoke, and more.

An Energy Recovery Ventilator: Great for Winter AND Summer

Monday, December 5th, 2016

To keep as much heat trapped as possible indoors and prevent cold drafts in winter, a house must have extensive insulation and air sealing. This may help with comfort and energy efficiency, but it also leads to a build-up of indoor contaminants and air that can be too humid or sometimes too dry.

What can you do about this? Open up the doors and windows for some fresh air? No, that just ruins the whole point of having a home insulated in the first place. All the energy used for the heating system simply goes to waste.

But what if you could recover that energy and use it to heat up fresh air coming from the outside? That’s just what an energy recovery ventilator (ERV) does, and it’s a great solution to unpleasant indoor air during winter.

You May Need Professional Duct Sealing

Monday, October 24th, 2016

Most homes have a ventilation system with ductwork to circulate air—both heated and cooled—throughout the rooms. Because the ductwork is hidden from sight in walls and ceilings and closed-off spaces like the attic, it’s easy for homeowners not to give them much thought. But ducts often develop air leaks in them over time, and unless these leaks are professionally sealed, it will have a negative effect on home comfort and energy performance.

How a Whole-House Humidifier Helps Your House in Winter

Monday, October 17th, 2016

The most important step for prepping your home for the coming winter weather is to arrange for maintenance for the heating system. (Sign up for our Comfort Club and you can get started right away!) But there are some other steps to take as well, including making upgrades to the HVAC system. One that we recommend for many homes is putting in a whole-house humidifier. The installation work is a job professionals must do, but you’ll receive numerous benefits from the system during the winter—and the winters to come. Below are a few of the ways a humidifier will help during cold weather:

A warmer-feeling house

A humidifier doesn’t raise the indoor temperature when it’s running, even though it feels like it does. What’s actually occurring is that the moisture levels in the air make it easier for the human body to retain heat. When the humidity levels are too low, heat escapes rapidly through the skin by perspiration. Proper humidity balance thanks to a whole-house humidifier takes an unpleasant edge off the cold.

Lower energy bills

Dry air forces you to keep your heater running more often in order to overcome the effects mentioned above. With a humidifier working, you can reduce the amount of money you spend running the heater, often by 25% over the winter.

Improved health

Extremely dry conditions weaken the immune system. When sinus membranes dry up, colds and flus can spread quickly from person to person. A humidifier will help lower the incidences of illness in your house over the winter.

Protection for wood and painted surfaces

Low moisture can cause wood to crack and painted surfaces to peel. This can be especially serious for precision musical instruments, but almost any home will benefit with a humidifier to protect its building material.

Why Your AC Can’t Handle High Humidity

Monday, August 1st, 2016

Heat is only one of the enemies of comfort during our summers in Raleigh. The other one is humidity. The higher levels of moisture in the air makes is harder for the human body to release heat through perspiration, which is why humid days feel hotter than the actual temperature. A 90°F day is hot no matter which way you look at it, but a 90°F day with 80% relative humidity can be utterly miserable.
