On a pleasant day with mild outdoor temperatures, opening the windows to your house is a wonderful way to let fresh air circulate through the rooms. Modern houses don’t “breathe” well because of the heavy insulation on them to improve energy efficiency, so letting outside air in to push out the stale air helps improve indoor air quality.
You can’t have the windows open every day, however. During heavy rains or when the heat is extreme, opening the windows will make it much harder for you to stay comfortable since it will change the temperature indoors. Keeping your house sealed up for long stretches can make indoor air quality far worse.
But you don’t have to let it be this way! With our help, you can enjoy better air quality with the windows closed and your house sealed up. We’ll explain how.
Indoor air quality (IAQ) has never been more on the forefront of people’s minds than now. But poor IAQ has troubled homes for the last few decades: as construction creates more airtight houses to boost energy efficiency, indoor contaminants have fewer ways to escape, and less fresh air sweeps through to help keep the air clean. Chances are high that if you’re concerned about the IAQ of your house, you have good reason.
The later summer can be the worst when it comes to heat and humidity, especially in Florida. It can also be the worst when it comes to air conditioning system performance—a lot of pressure and stress have built up on the AC components in the last few months, and when it gets even hotter, the system may start to lose capacity or even break down.
The ductwork in the modern home is often substandard, as if the original builders of the house didn’t put much thought into the placement or materials of these important air channels. We’ve seen plenty of poor ductwork in the more than two decades we’ve worked on HVAC systems. This is why 
Winters here in North Central Florida are mostly pleasant, but we do have stretches of days when the temperature drops to the point where heating systems have to come on. Most people have heaters that use ductwork to move heat to the various rooms, such as furnaces (electric or gas) and heat pumps. Unfortunately, no matter how well your home’s heater works, you’ll run into trouble if the ductwork is leaky.
