Two Reasons You Need to Replace Your AC & Furnace at the Same Time

You decided it’s time. Time to replace your A/C unit or your furnace. Builder’s Heating & Air Conditioning wants to make sure you consider all the options before you write a check. For example, sometimes it makes more sense to do an entire HVAC replacement, in other words, replace your heating AND cooling systems at the same time. There are two major areas of emphasis and each one has many factors to consider.


As a rule of thumb, a furnace will last longer than an air conditioner. If the A/C unit is 10 years old or more AND the furnace is 15 years old or more, then it’s a good idea to replace both. They are nearing the end of their normal lifespan and new units will certainly be more efficient. 


Speaking of efficiency, here’s another factor to consider. Your furnace and air conditioner are like conjoined twins. Because they share the indoor unit, the blower and air handler, each unit should have roughly the same efficiency rating. If you are upgrading your A/C unit to a higher efficiency model, but don’t upgrade the indoor unit, you are going to be wasting some of the money you spent on the efficient air conditioner. The same is true if you upgrade only the furnace.


It will cost less money to replace just one system. The question is does it make any sense to wait and have to replace the other in the near future. Sometimes you can get a better price when you replace both units at the same time. Make sure you call Builder’s to learn about any promotional offers or special financing available. Many factors determine the cost of heating and cooling systems:


In air conditioners, this is measured by the SEER rating. Furnaces have an AFUE percentage rating. In both cases, the higher the number, the more efficiently it uses energy. High efficiency usually means you pay more up front but will save more money in lower utility bills.


A larger system, measured in tonnage for A/C units and BTUs for furnaces, will cost more. The important thing to remember is bigger is not always better. Only an expert technician can determine what size HVAC replacement is best for your Denver, CO house.


There are many features and options available to increase your home’s comfort. Variable speed technology, noise reduction features, and modern smart thermostats can add to the HVAC cost, but all offer significant advantages.
