Replace Your Furnace and Central Air Conditioning Systems at the Same Time for Maximum Savings

October 19, 2016

A famous writer once said “There’s nothing like staying at home for real comfort.” Coming home from a long, cold, dreary day and being greeted by a nice, warm, cozy home is something to look forward to, all thanks to the wonders of modern technology – more specifically, your heating system. Or how about those random hot fall days that seem to come out of nowhere and leave you wanting to arrive in a nice, cool, air-conditioned home? Without your Air Conditioning (AC) system, comfort would be hard to find when those days roll around.

Your furnace and AC systems are so important that when it comes time for the seasons to change, you usually rush to make sure they are in prime condition and up to the task you are about to ask of them. However, this is also the perfect time to evaluate whether your heating and cooling systems are out-of-date, and might need to be overhauled or replaced. If your furnace and central AC systems are 12 years old or older, they’re wasting energy and you should think about replacing them now – before they fail. Even better, you can qualify for special early replacement rebates from Mass Save. With new efficient equipment, you can prevent discomfort during crazy cold winters and extremely hot summer temperatures and avoid last minute repair bills. You could also keep more cash in your pocket over the long term by saving on your electric and/or natural gas bill(s).

When thinking about updating these systems, we tend to consider only the system that we need for the current season. For example, since fall just started you might think it’s best to replace your heating system now, while not giving your AC system a second thought. However, replacing both systems at the same time can save you a lot more money and energy.

Consider the following:


The newest heating and air conditioning systems are created with the highest efficiency in mind, so they tend to use a lot less energy than your current systems while doing the same amount of work – all of which translates to less energy usage and lower energy bills!


Pairing up an old AC unit with a new furnace (or vice versa) means you may not be allowing the new system to perform to its highest standards. Replacing only one could result in your newer appliance working overtime to make up for the older system, usually because both the AC and furnace use the same air handler or blower system. On the other hand, when replaced at the same time, matching technology between the two systems allows them to work together for maximum efficiency.


In addition to making sure that aligned technology brings you maximum efficiency, replacing both systems at once gives you the opportunity to shop for package deals and can also save money on installation costs. You may even have the benefit of having the same warranty period on both appliances.

At Mass Save, we like to make sure you get the most out of your energy usage while saving money, and that’s why we offer rebates of up to $1,750 for replacing your furnace and AC units. You can find all this information here.

So take some time this season to see if your furnace and AC units need to be replaced, check out our rebates, and make the change that will save you money and energy, while keeping your home more comfortable than ever!
