6 Signs It’s Time to Pull The Plug on Your Old HVAC Unit
Air conditioning systems are one of the largest investments made by a Bay Area homeowner. You probably want to hold on to your HVAC system for a few more years. However, sometimes it is more cost efficient to trade in an old and outdated model for a new one. Damaged or old HVAC units can increase your energy bills and result in poor indoor air quality.
These are a few signs that it is time to replace the HVAC system:
1. Your HVAC System is a Decade Old
The Department of Energy recommends replacing an HVAC system every 10 – 15 years. Modern air conditioners come with better technology that makes them more durable. Components of an air conditioner begin wearing down after the 10-year mark. Older air conditioners may also use R-22 refrigerant that is outdated and harmful for the environment.
2. Repairs Are On the Rise
You should not hold on to the air conditioner when repair bills come to a half of the cost of a new unit. Purchasing a new system is sometimes the better decision.
3. Increasing Energy Bills
Your energy bills for the same month in different years should be more or less similar even if seasonal fluctuations are normal. High energy bills are a tell-tale sign of replacing or servicing your existing HVAC system. The HVAC system is responsible for a major share of the electricity bill. Regular maintenance will add to the lifespan of your air conditioner. However, there comes a time when you have to upgrade to a better and newer model if you want to cut down your energy bills by almost 20%.
4. Maintaining Comfortable Temperature
Aging HVAC system may struggle to keep the indoor temperature consistent. This can be because of inaccurate or damaged thermostat, clogged filters, low fluid levels, damage to motors, and cracked ducts. Temperature inconsistencies mean that you air conditioning system is not powerful enough. It can also mean that there is something wrong with the ductwork. You can ensure a comfortable indoor temperature by opting to upgrade your HVAC system.
5. Increase in Dust
An HVAC system is not responsible for just delivering conditioned air in a house. It is also responsible for providing proper ventilation. Your system should improve the indoor air quality by working in an efficient manner. It should remove dust, dander, dirt, and other debris. It should also keep humidity levels under control at the same time. Your air conditioner may not be efficient anymore if you notice an increase in dust inside your home. Dust results in poor indoor air quality as well. You may have an increase in mildew and mold if there are unusually high humidity levels.
6. Funny Smells and Odd Sounds
Sometimes, an unusual smell is nothing more than dust burning off the HVAC system. However, you should still have a trained executive inspect the equipment to be safe. It is possible for melting wires and mold in the duct to produce funny smells.
The same holds true for odd sounds. Well maintained systems should have a relatively quiet operation. Individual components may become older with time. You may notice noises, such as squealing and grinding. You should have the system inspected immediately if your device makes these unusual sounds.
