Like any other mechanical device, an HVAC system has a lifespan. As it approaches the end of its lifespan, its efficiency suffers, and it needs more frequent or expensive repairs. Here are a few telltale signs that its time you replace your Venetia, PA, HVAC system.

1. Sudden Increase in Electricity Bill

In as much as it is normal to spend more on electricity during the summer, the difference shouldn’t be significantly high. If it is, then the performance and efficiency of your HVAC system is less than it should be. Typically, an HVAC system has reduced efficiency after five years with little maintenance and after 12 – 15 years with top-notch maintenance.

Even with regular maintenance, the constant wear on your HVAC system will mean it’s normal lifespan is usually about 15 years. Choosing an energy-efficient model when it’s time for a new installation will save you 20% or more in energy savings over your current system.

2. Frequent HVAC System Repairs

It is normal for your heating and cooling system to need one or two small repairs over time. But when the major parts start needing replacement or repairs, it may be better to invest in a new system rather than repair the existing system. When repairs approach 40% of the cost of a new system, or you’ve had a number of repairs in a relatively short period of time, it’s usually wise to invest in a new system.

3. Uneven Temperature and Humidity

Sudden and uneven temperatures are a common problem that arise with HVAC systems and may be an indicator that replacement is necessary. Your system could be short-cycling, which leaves some rooms more humid than others, or because there is a breach in your ductwork.

As soon as you notice the uneven temperature, call a professional to determine what type of repair will correct the problem, or if the system is nearing the end of its lifespan.

No matter how well you take care of your HVAC, it will reach the end of its efficient usefulness and will need to be replaced. Call the experts at Valley Heating and Air Conditioning Inc., and we’ll gladly assess your system to determine if a repair is warranted or if it’s time to perform a load calculation for a new HVAC system.
