Indoor air quality (IAQ) is a major topic for residential and commercial buildings today. The US Environmental Protection Agency has identified low IAQ as a significant health threat in the country, with many buildings having air that is 2 to 5 times worse than the outdoor air on average—and it can often get much worse. The source of much of the trouble is the low levels of fresh air circulation through buildings because of tight construction and heavy heat sealing designed to improve energy efficiency. In other words, the better we construct buildings, the less fresh air they get. Progress has a price.
If you’ve heard about the problems with IAQ, you may wonder how you can best protect your family’s health and improve household air quality. We can help: we’re experts in indoor air quality in Macclenny, FL and throughout North Central Florida. We have several tips for how to improve your home’s IAQ, both tasks you can do yourself and professional services we offer.

Heating a home in Florida during our mild winters is a bit of a juggling act. We don’t need our heating systems to run every day, through most of the day, as in a cold northern state where the weather is routinely below freezing. We’ll need our heaters on certain occasions and run them long enough to keep away the cool chill of days that are in the 50s. This makes it easy for a heater to get a house 
Florida is notorious for its high humidity, and we can expect to see relative humidity levels over 60% on most days, which is the point where the moisture in the air will have a negative impact on comfort. When you combine relative humidity above 60% with days above 90°F, it can make it difficult to scrape through the day, even with the best and most reliable air conditioning system.
One of the best ways to tell when a heating system is ready for a replacement is basic age. Each heater comes with a manufacturer’s estimated service life. Once the system is beyond that age, we advise you to think about replacing it, even if the unit still seems to function well. It doesn’t mean you should automatically replace it. But it’s time to ask yourself serious questions about the heater’s performance so you’ll know when to pull the trigger on a new system.
We run our HVAC systems throughout the year in Central Florida, often with the air conditioner running even during winter—and heating systems taking over for a few days here and there. If you keep a close eye on your utility bills (always a good plan!), you should have an idea of what your seasonal heating and cooling costs are, and they should remain steady through the season.
Regular maintenance, as we’ve discussed before, is key to keeping your air conditioner running smoothly for longer. This is something that should always be handled by a professional technician, someone who knows the ins and outs of central AC systems and can spot
