Deciding When to Upgrade an HVAC System

HVAC systems don’t live forever, and older systems are much less efficient than modern technologies. While you can extend the life of your system through regular maintenance, if you’ve had your HVAC for 10 years or more, it’s likely time for a newer unit. Common signs that an HVAC is getting to the end of its service life include:

• Your energy bills keep increasing
• Your heater or AC seems to run constantly
• The system makes unusual noises when turning on or operating
• You notice uneven temperatures throughout your home
• The air coming from the vents feels room temperature
• You’re spending a lot of time and money on repairs

As your HVAC system ages, it becomes less efficient, and older units generally aren’t as good at maintaining heat and cool air as newer options. Most of a home’s energy consumption and utility costs are related to heating and cooling, and replacing a system can save a household 20-40 percent on their bills according to the U.S. Department of Energy.

To put that in simpler terms, a new HVAC system can save you money every month. To decide whether those savings are worth the cost of installation, you’ll need to do some research.

Finding Efficient HVAC Options

HVAC equipment is designed to meet specific energy requirements. Each unit has a Seasonal Energy Efficiency Rating (SEER). The higher the SEER number, the more efficient the equipment. The Department of Energy recommends choosing a unit with a SEER of at least 15. To keep your utility bills even lower, look for units that are Energy Star qualified. A new Energy Star-certified central air conditioning unit may be up to 15 more efficient than a standard model.

While you’re making a change, you can often find other ways to increase efficiency. Updating your HVAC also means you can exactly match your home’s energy consumption needs to the size of equipment. According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers, a poorly sized HVAC system can lead to poor moisture removal and even mold growth (not to mention higher bills).

To get an appropriate system — and keep costs low — you’ll need to plan carefully. A reputable installation company can ensure that your system is correctly sized to your home, but you might not get the best rate for the service unless you compare every local option.

Avoid Overpaying When Upgrading Your HVAC

If you’re ready for an energy-efficient upgrade, online resources can help you get started the right way. Keep these tips in mind:

• Consider waiting until off-peak seasons. Many HVAC companies do most of their installations in the summer (which is when most air conditioners are pushed to their limits). You might find special incentives when shopping during the spring or fall.
• Check with your local utility company before making the decision. Many utility providers will rebates and other incentives for homeowners who opt for energy-efficient appliances. Additionally, some states may offer tax credits or deductions, so read about available programs to see if you qualify.
• Consider all of the costs of installation. That includes the money you’ll save on your utility bills over time. A unit that costs a few hundred dollars more might pay off the difference within a few years.

Finally, remember that the work doesn’t stop once you’ve upgraded (though it gets much easier). Schedule regular maintenance and tune-ups for your new system, and look into other ways to improve efficiency. For instance, adding a programmable “smart” thermostat can provide additional savings of up to $180 per year.

An HVAC Upgrade Can Be a Solid Investment

When upgrading, make sure to compare at least 3-4 reputable companies. Look for reviews from past users, read about the company’s insurance policies, and talk to them in person. While many installers won’t provide a firm quote without visiting your property, you can get rough estimates online, then compare those estimates to create a shortlist of reliable HVAC contractors.

Online resources allow you to easily consider potential costs, and when you’re ready for a new system, you’ll know you’re getting a great value for your money. Few home improvements are as important as a new HVAC, and comparing your options, you can make an informed decision.
