When to Upgrade an HVAC System

Regular maintenance can help to extend an HVAC system’s service life, but older systems are inefficient when compared with modern technologies. That means higher utility bills (and in some cases, much higher energy bills). By avoiding an upgrade, you might end up paying more than necessary.

Generally, if a system is more than 10 years old, you should probably start budgeting for a replacement. That’s especially true if the system runs constantly or if you’ve noticed any of these issues:

• The system constantly turns on and off
• The outdoor part of your AC leaks
• You hear excessive noise during startup or while the unit operates
• You have trouble keeping your home’s temperature consistent
• Air coming from the vents isn’t hot or cool enough

A new HVAC system is a major expense, but it’s also one of the most important investments you can make in your home. A high-quality, energy efficient unit can help you recoup some of its costs, but you’ll need to research carefully to get the best possible value.

Energy Efficient HVAC Systems

While replacing an HVAC system is an expensive endeavor, cutting your electrical consumption could save you money in the long run. Newer equipment operates more efficiently than older systems, and if you’re already paying for maintenance and repair services for your old system, you’ll cut out another expense.

So, how much can you expect to save? According to the U.S. Department of Energy, a new air conditioner can save a homeowner 20 to 40 percent of their cooling energy costs — even if the old unit is only 10 years old.

To take advantage of the latest tech, look for models with Energy Star and EnergyGuide labels. Central AC units and furnaces bearing these labels are nearly 15 percent more efficient than standard models. In fact, a new energy efficient furnace can save $85 per year (and potentially more, depending on the efficiency of your old unit and other factors).

Factors to Consider When Upgrading

The cost of a new HVAC system will vary depending on where you live, the size of your home, and the features you want. Don’t rush the decision — you’ll want to gather several quotes and assess your home’s energy needs before you buy.

Some tips:

• Consider paying for an energy audit. These services use visual inspections and special tools to determine where you’re wasting energy (and money) in your home; auditors make a list of recommendations to help you save. Some utility companies offer low-cost or free energy audits.
• Know what you need. You’ll also need to know your home’s square footage. HVAC systems measure their output in British Thermal Units (BTUs). A smaller home will usually need a system with fewer BTUs, though a reputable HVAC installer can help you make an appropriate decision. If you know your home’s square footage, you’ll be able to easily collect and compare quotes.
• Look for incentives. For even more savings, look into whether your utility company offers rebates for energy-efficient systems. Your installation company can help you take care of the paperwork for rebates, tax credits, and other incentives, which can help you keep the project within budget.

Once you’ve made a decision, make sure to maintain your new system. Regularly change air filters, properly seal all ductwork, and schedule regular tune-ups. Consider using a programmable thermostat, which can save you up to $180 per year in energy costs when properly used.

Comparing Options for a New HVAC System

Most importantly, look at as many options as possible. Use the internet to find HVAC companies operating in your area, then collect estimates. Many contractors won’t provide firm estimates until they’ve evaluated your property, but by doing your research, you can find reliable installers that are within your budget.

The internet can provide all the information you need to improve your homes with confidence. Remember to research carefully, looking at multiple units and installation services. By taking a few minutes to understand your options, you can enjoy the comfort and peace of mind that comes with a brand-new HVAC system — without overpaying for the privilege.
