Keeping your HVAC system in good working order is essential to a comfortable home. But sometimes repairs aren't enough, and replacement becomes the smarter — and more cost-effective — choice. Here are four signs it may be time for a new unit.
1. Rising Energy Bills
Every time your HVAC system runs, it adds to your heating or cooling bill. If your energy costs are climbing without a change in how you use your system, it's often a sign your unit is losing efficiency.
2. Old Age
According to the U.S. Department of Energy, a typical air conditioning system lasts 15 to 20 years. If your unit is approaching or has passed that range, it's worth having it evaluated for replacement rather than continuing to invest in repairs.
3. Poor Air Quality
Weak airflow, inconsistent heating or cooling, and increased allergy symptoms can all point to a system that's no longer performing the way it should. You deserve optimal air quality from your HVAC system, not compromises.
4. Constant Repair Needs
If you find yourself calling for repairs again and again, the cumulative cost can quickly approach — or exceed — the cost of a new unit. At a certain point, replacement is the more economical choice.
If any of these signs sound familiar, we can help you find the right replacement system for your home.
