Generally speaking, if you have an HVAC system that’s more than 20 years old, it’s probably not as energy efficient as the ones that are currently on the market. Replacing it would likely save you thousands over the coming years while also making your home that much more comfortable.
However, if your HVAC system has not been maintained properly, you may need a new one sooner. In most cases, though, we will do HVAC repair instead of HVAC installation because the repairs will typically cost that much less. It’s not uncommon for people to find that their repair costs have gotten so high and so frequent that a new HVAC system is recommended.
