Replacing Your Outdated Heater

While heat pumps last for about 10 years and furnaces can provide reliable heat for 15-20 years, all heating equipment needs to be replaced eventually. If your heating system is no longer operating efficiently or providing reliable home comfort, frequently needs repairs, or your heating bills are rising, it is probably time to consider a new heater.

Replacing your heater offers:

  • Long term money savings
  • Higher efficiency levels
  • Updated safety features
  • Lower heating costs
  • Improved home comfort
  • Generous warranties

Although we often replace heaters that have completely failed, many of our customers choose to replace the heating system before it completely dies. If your heater is still technically working, but performance has significantly decreased or heating bills are too high, replacing the system can help you save money in the long run. For your convenience, we offer financing options to help make your purchase easier.

Choosing a Heating System for Your Home

When you decide to upgrade your heating system, the first step is to decide what type of system is best suited for your home. The most popular home heating systems in our area are heat pumps and furnaces. There are advantages to each type of heating system. Furnaces are popular for high energy efficiency, fast and reliable heat, affordability, and cost effective home heating.

Heat pumps offer advantages such as:

  • High energy efficiency
  • Quiet operation
  • Heat and air conditioning in one system
  • Better indoor air quality

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
