6 signs you may need a new HVAC system
1. AGE
If the HVAC system is more than 10 years old, it could be time to begin budgeting for a new unit. Many modern, efficient systems may last 12 to 14 years with routine maintenance. But it's good to keep an HVAC system's age in mind so you can readily recognize when it might start to fail.
2. LONGER OR CONSTANT RUNNING TIMES
An efficient, properly working system will quickly heat or cool the home and then turn off. A system that is turning on repeatedly or having to run for awhile before the set temperature is reached could be nearing the end of its utility.
3. STRANGE NOISES
Groaning, banging or loud humming noises should be addressed. While these noises may indicate that certain components need maintenance or replacement, they also could be symptoms of age and a system nearing failure.
4. FREQUENT REPAIR VISITS
Knowing the HVAC company's repair person by name is a sign that the system has required too much work in recent months. Repeated issues and repairs are probably signs that it's time to consider a system replacement.
5. HIGHER BILLS
Sticker shock when receiving electricity or gas bills likely mean the HVAC system isn't working efficiently and might need to be replaced.
6. POOR INDOOR AIR QUALITY
If the home is dusty or humid or even if allergies seem to have cropped up out of nowhere, this could indicate a poorly functioning HVAC system.
HVAC systems are vital to keeping indoor environments comfortable and safe. Such systems may exhibit certain signs that indicate they need to be replaced.
