The Most Common HVAC Issues in Older Homes
HVAC issues can adversely affect your home’s internal climate. Blown circuit breakers, dirty air filters, refrigerant leaks, and more can make your home clammy and uncomfortable while significantly reducing your unit’s efficiency and lifespan. Below are some of the most prevalent HVAC issues older homes experience.
1. Poor Indoor Air Quality
Poor indoor air quality is detrimental to your health and can cause multiple respiratory problems, fatigue, congestion, dry skin, and more.
The main culprit for poor indoor air quality is a dirty air filter. Dirty filters won’t be able to catch pollutants within your HVAC system efficiently, allowing dust, debris, and other contaminants to enter your home, significantly reducing the air quality. Replacing the filter once a month will prevent impurities from tainting your home’s air, allowing your HVAC unit to produce fresh, clean air. If you have pets, you may want to consider replacing your filter more often.
2. Restricted Airflow
HVAC systems generate warm and cool air and push it inside your home. However, your unit can’t maintain a comfortable indoor temperature if something obstructs airflow.
The most prevalent cause of restricted airflow is dirty air ducts and vents. Dust and grime accumulate within your home’s air ducts over time and can restrict air flowing from your HVAC unit. Regularly cleaning your air ducts and vents is one of the best ways to ensure optimal airflow and preserve your desired indoor temperature.
If you clean your air ducts and still experience restricted airflow, it’s likely an HVAC system malfunction, such as a broken blower motor. If you suspect your HVAC unit has a defective blower motor, contact a professional technician for repair services.
3. Refrigerant Leaks
Refrigerant leaks are common in older HVAC systems. Once the unit’s refrigerant tank cracks or corrodes, refrigerant slowly seeps out of the HVAC unit and pools around the system.
Refrigerant leaks often look like water leaks, so inspect the liquid closely. Air conditioners need refrigerant to function and will lose efficiency without it, leading to premature breakdowns and repairs. Refrigerant leaks will also cause your HVAC unit to work harder to maintain indoor temperatures, dramatically increasing your monthly energy payments.
If you see pooling around your HVAC system or notice a sudden decrease in efficiency, check the unit’s refrigerant level and contact a technician to refill it if necessary.
4. Outdated Equipment
HVAC systems typically last 10 to 15 years before requiring a replacement. Although you can extend your unit’s lifespan with regular maintenance, you should consider replacing the unit once it hits the ten-year mark. Upgrading to a newer model will provide better heating and cooling and require less energy, potentially reducing your utility bills.
Thermostats will also require a replacement every ten years or so. Older thermostats are less advanced than modern models and often cause more frequent cycling, causing significant wear and tear on the system. Installing a modern thermostat will give you more control over your home’s internal climate.
Most heating and cooling professionals recommend installing a programmable or smart thermostat for optimal performance. These thermostats can help you maintain a comfortable indoor temperature while reducing wasteful energy consumption. You can program them to your schedule, allowing you to have complete control over your indoor comfort. Smart thermostats also enable you to control your home’s temperature while you are away.
5. Air Duct Leaks
Your home’s duct system transports air from your HVAC system and distributes it evenly throughout your residence. Air duct leaks prevent even distribution and can make it difficult to maintain a comfortable temperature. Duct leaks can also skyrocket your energy bills if you don’t address the issue quickly.
If you experience an air duct leak, contact a reliable air duct sealing company for immediate repairs. Professionals use high-quality air duct sealers to patch holes and leaks within the ductwork, improving their efficiency and lifespan.
6. Zoning Issues
Most older homes have one thermostat that controls temperatures throughout the house. However, manufacturers design modern HVAC units to heat and cool individual zones within your residence with separate controls, allowing you to warm a bedroom without heating unoccupied rooms and reduce energy waste.
Installing a ductless heating and cooling unit in multiple rooms is one of the best ways to improve zoning issues. Ductless systems provide individualized indoor temperatures, enabling you to heat one room while cooling another. You can also replace your entire heating and cooling system with a newer, more advanced variation to improve your home’s zoning problems.
