Your FAQs About HVAC Systems

March 3, 2016

Your HVAC system could be your home's most complex and expensive component, but you don't need to be an expert to understand how to get the most from it. Paying attention to the basics will help you extend its lifetime, ensure your comfort and reduce energy costs.

Does the Filter Matter?
If you want to lower energy bills and extend the life of your system, pay attention to both the quality of your filter and when you change it. The air filter stops dust from entering your system to keep the parts clean. A higher quality filter traps more airborne particulates, keeping the system cleaner. Running your HVAC system with a dirty filter slows the air flowing through it, which increases the time it has to run, stressing its parts and driving up energy costs. When choosing your next filter, consult the owner's manual first to find the most suitable filter the manufacturer recommends.

Does it Really Need Preventive Maintenance?
HVAC systems need professional cleaning, lubrication, and adjustments to keep them running at peak efficiency. Annual service pays off in better durability, dependability, and lower heating and cooling bills. The inspection also includes an assessment of the ductwork. Duct leaks increase energy bills and lower indoor air quality.

When Should You Replace It?
Most HVAC systems last between 12 and 20 years and lose efficiency as they age. It's almost always better to replace the system instead of paying for increasingly higher energy bills and repair costs.

Is Bigger Better?
Bigger is definitely not better when it comes to HVAC equipment. A system that's too large for your home will run in short cycles, which drives up energy costs, increases wear on the parts, and reduces indoor comfort. Too small a system won't be able to handle weather extremes. Before selecting a replacement system, insist that your HVAC contractor complete a load calculation for your home using Manual J software. Managing the basics of your HVAC system cuts its operating costs without sacrificing comfort. To learn more, contact Lozier Heating & Cooling, providing HVAC services for Des Moines homeowners.
