Your home’s heating system is more likely to break down completely during the coldest days of the year. The average person doesn’t keep their home’s HVAC unit at the forefront of their thoughts during the holiday season, but your home’s furnace giving out during this time is not a situation any homeowner wants to face. The same can be said of your AC unit, which is more likely to give out during the summer months due to overwork and weather conditions.
When the time comes to call a technician to evaluate your HVAC unit due to malfunction, the damage is already done. If you are one of the countless homeowners with 10- to 12- year-old systems, you will be faced with a decision about investing in the comfort of your home.
When replacing an AC or furnace, it is important to consider how the new equipment will affect the system as a whole. Mixing a new furnace with an old AC unit will decrease the system’s overall performance, and vice versa. By replacing only one part of the system, you will inadvertently lower the performance of both parts. It is best to replace both parts at the same time. Some manufacturers will not even honor warranty agreements when a new furnace is paired with an old AC, as this arrangement increases the probability of product failure. If you’re replacing one part of your HVAC unit with new, efficient equipment, the decision not to update the other part at the same time will lead to avoidable problems, frustration, and additional costs.
When investing time and money in your home, it is smarter to pay a higher price once, to obtain an energy- efficient, highly responsive, state-of-the-art HVAC system, than to try to repair an outdated system or combine new equipment with old. You might think that saving a couple of hundred dollars by keeping as much of your old equipment as possible and only replacing what “needs” to be replaced is the correct choice. This decision will save you money up front, but unfortunately it will cost you much more in the long run. Mixing and matching new and old components puts a strain on both and leads to costly work that could be avoided if the furnace and AC systems were replaced in tandem instead. The heating and air-conditioning systems of today are highly efficient and use far less energy than systems built more than 10 years ago. So, when you invest in your home, invest for the long term and enjoy the comfort of a new furnace matched with a new AC.
