When to Replace an HVAC System
The comfort of a home revolves around its most expensive appliance: the HVAC system. Unfortunately, no matter how well an HVAC unit is cared for, it won’t last forever. The time will come when the equipment will need to be replaced.
Signs it’s time to replace an HVAC system include:
- The system is more than 10 years old
- The unit has been repaired more than once
- The equipment can’t maintain comfortable temperatures
- There are uneven temperatures throughout the home
- The unit requires frequent repairs
- Repairs are more than 50% of the cost of a new unit
- The cost to heat or cool the home has risen drastically
- Size of the HVAC system is insufficient for home expansion
Although no one looks forward to paying to replace their heating and cooling systems, doing so has some great benefits. The new equipment will perform much more efficiently than the old, which means lower energy bills. Also, the new unit will have better performance, meaning enhanced comfort, fewer issues, and less frequent repairs.

What Size HVAC System Do I Need?
Size is one of the most crucial factors when it comes to replacing HVAC equipment. The easiest way to determine the appropriate size is to have an HVAC professional perform a load calculation. This calculation considers several factors, including the square footage of the home, ductwork, numbers and types of windows, insulation, and local climate. When an HVAC system is correctly sized, it will perform more efficiently and effectively, reducing energy costs and maximizing comfort.
How Much Does a New HVAC System Cost?
HVAC replacement isn’t cheap, as most new systems cost several thousands of dollars. Exact pricing will be dependent on several factors, including the brand and type of system selected, the size required, and any additional features that may be desired. The condition of the current ductwork should also be considered, since replacing ductwork will cause the installation to be more expensive.
