May 20th, 2019

Do you usually think of your thermostat as a part of the HVAC system? Or do you consider it something separate, a basic control panel on the wall that you have to adjust occasionally when somebody in the house starts complaining about it being too hot or too cold?

The thermostat is a control panel, but it’s also an essential part of the HVAC system. The thermostat connects you to the air conditioner and blower fan, but it also monitors temperatures in the house to detect and regulate how the AC works. If a thermostat has faults, such as miscalibrations or lost connections, it can create a slew of cooling troubles in your home. Often, those troubles may not at first seem like they’re coming from the thermostat, although professional HVAC technicians can track down the source for accurate air conditioning repair in Bellevue, WA.

You May Not Have Enough Insulation in Your Home

February 11th, 2019

woman-shivering-in-sweaterWe didn’t experience cold weather anything like what recently struck the Midwest and Eastern US. However, the intense cold weather can serve as a warning to everyone—many homes do not have proper levels of insulation. The North American Insulation Manufacturers Association estimates that 90% of homes are under-insulated.

Poor insulation means immense amounts of energy go to waste attempting to make up for the heat that escapes through the walls of a home. According to the Environmental Protection Agency, a house can save around 15% on its annual heating and cooling bills with better insulation.

Newer building codes have improved insulation, but there are many older buildings still around with subpar heat sealing on them. You might be living in one of those and paying higher bills than you should without realizing it.

What Can I Do for Better Indoor Air Quality?

January 14th, 2019

woman-relaxingThis is a question we hear often from our customers in the Seattle area: “Do you have recommendations for better indoor air quality?” We understand why people ask this: indoor air quality in Seattle, WA is often quite poor, and people are becoming more aware than ever of the many pollutants that come from inside their home, rather than from outside. Homes have more insulation in them than ever before, and although this improves energy efficiency for the HVAC system (less heat loss in winter, less heat gain in summer), it also causes a drop in IAQ because there’s scant fresh air circulation to replace the stuffy and pollutant-filled indoor air.

So, back to the question …
