For first-time homeowners or others that are inexperienced with the HVAC functions gave in a house, there are some things to consider before diving into replacements for brand-new HVAC equipment. Whether you’re looking to improve the heating or cooling systems for your home, you should first take a look at the insulation throughout the house. Much prefer a styrofoam cooler, the insulation in the walls plus ceiling job to keep cool air inside the house in the summer, plus hot air indoors during the winter. With poor insulation in a house, even a top of the line HVAC method will be hampered as the air leaks out of the house through the roof or cracks in the walls. That’s why insulation should be checked first, before even considering a new heating or cooling device. In that same vein comes the importance of knowing whether an attic fan is needed. Made to push hot air in the attic out of the house, attic fans can reduce heat stored inside a house considerably. However, having an attic fan is a fruitless endeavor if the house already has excellent insulation; Plus, attic fan usage can entirely cause the cooled air to circulate out of the house faster if the insulation in the roof is poor; Really, an attic fan should only be considered if the insulation in the ceiling is solid, however the insulation in the roof itself needs work.
