Should I Repair or Replace My HVAC System?

When your trusty heating and cooling system begins to act awry, you're often met with a common dilemma: to repair or replace your HVAC unit. Several factors need to be considered when weighing the pros and cons of both options. While some may assume that paying for repairs on a dated system is an effective solution, this is not the case. You may end up spending more in the long run due to repeat repairs. Sometimes, the best option is to start fresh with a brand new system.

Our HVAC specialists are here to help you determine the best course of action for your home. To an untrained eye, it can be challenging to spot the need for replacements over a simple repair. To learn more about the telltale signs of a necessary replacement, keep on reading!

Age of the Unit

The age of your system should be kept in mind when debating a necessary replacement. Specifically, the lifespan of furnaces and air conditioners is around 15 to 20 years. If your system is older, it's likely that it's less energy-efficient and can result in costly energy bills. In that case, we would recommend upgrading your system to a newer and more efficient model.

When considering the lifespan of your units, remember that usage plays a role as well. For example, if you were to vacation for a couple of months out of the year and your HVAC system was set on an energy-efficient temperature for the vacant home, your unit would potentially end up lasting longer than expected.

Frequency of Repairs

Suppose you've been scheduling back-to-back repairs for your inefficient heating and cooling system. In that case, we would recommend upgrading your system altogether as the best course of action. When considering the costs of repetitive repairs on a system that is soon to retire, it's beneficial to replace your system sooner rather than later.

If you can't rely on your HVAC system to be dependable enough to meet your heating and cooling needs consistently, it's time to get a new system. You wouldn't want to deal with a broken-down heating system in the middle of winter or an insufficient air conditioner throughout the summer, so make sure your system is up to meet your heating and cooling demands!


Your HVAC system is supposed to heat and cool your home with ease. If it's not doing its job effectively, it can leave you and your household uncomfortable! If you notice that some rooms aren't effectively cooled or heated, no matter how many repeat repairs are made, it may be time to upgrade your unit.

Energy Efficiency

Some homeowners may assume that hanging on to an older, less energy-efficient model is a better alternative to a replacement. This isn't the case! Your heating and cooling system has a direct impact on your energy consumption and monthly bills, so you'll want to consider your system's energy efficiency when debating the need for a replacement. Continuously spiked energy bills are a telling sign that you're in need of a new HVAC system.
