I need to replace my air conditioner, but my furnace works just fine. Is it true they need to be replaced at the same time?

Think of your air conditioner and furnace as part of a total system. That system will work better, longer and more efficiently if all of its components are matched in capacity and efficiency. By the same token, a mismatched system – one that mixes old technology with new – could decrease system performance and overall comfort.

For example, your new air conditioner will be capable of reaching a certain SEER (Seasonal Energy Efficiency Ratio). Because SEER is determined by a complete system combination, if your existing furnace and indoor coils are older or don’t match in efficiency and capacity, you might not get the efficiency level you paid for or be able to receive accurate information on what your rating actually is. Plus, an older indoor coil may even be dirty and clogged with particles, meaning more energy will be required to push air through the system.

Why are rating numbers important?

Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your heating and cooling bills can be. The federal government established rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio) and for heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).

I thought pollution was outside. Why should I be worried about my indoor air?

We spend about 90% of our time every day indoors. Today’s efficient, airtight homes are excellent at conserving energy, but that also makes them better at trapping potentially irritation particles inside the home. With the rising number of people who suffer from allergies and asthma, indoor air quality has become more and more important to our general health and well-being.

My children have allergies. Is there a way to improve the quality of air inside my home?

For people who suffer from allergies, we recommend American Standard Heating & Air Conditioning’s AccuClean™ Whole-Home Air Filtration System. It can clean up to an astonishing 99.98% of allergens from the filtered air that you family breathes. With AccuClean™, the majority of irritating particles, like dust, pollen, pet hair and dander, dust mites, mildew, lint, fungus, most tobacco smoke, cooking grease, and even bacteria, will be removed from the filtered air. In fact, AccuClean™ removes 100 times more allergens than the standard 1-inch throwaway filters that come with most systems.

How can I control my energy costs?

Controlling energy costs starts with your thermostat. You can save about three percent of your heating costs for every degree you lower your thermostat during the winter. And for every degree you raise your thermostat in the summer, you can cut cooling costs up to six percent.* Adding a programmable thermostat can also help you save energy, by allowing you to set different temperature settings depending on the time of day.

Just as important, your system’s components should have the highest possible energy efficiency ratings. Make sure you components meet the following minimums:

  • Air Conditioners: SSER ratings of 13 or higher
  • Furnaces: AFUE rating of 80 or higher
  • Heat pumps: HSPF ratings of 7 or higher

*Potential energy savings may vary depending on your personal lifestyle, system settings, equipment maintenance, local climate, actual construction and installation of equipment and duct system.

How do I know what size system I need for my home?

One of the first things Shelburne Heating & Air will do is conduct a complete energy analysis of your home. By measuring windows and checking insulation, ductwork and building materials, and reviewing a variety of other factors, we can determine the right size system and equipment for your home. We’ll even ask you questions about your existing comfort challenges, and make recommendations.

How much will my new home comfort system cost?

That depends. There are many factors that must be considered. These include:

  • The efficiency of the equipment
  • The size of your home
  • Whether the current ductwork installed is in good condition
  • Whether you will need a thermostat or an electronic air cleaner

In most cases, replacing your whole system, including both indoor and outdoor components, will result in a more efficient, longer-lasting system, but will also cost a little more.
