Can I Replace My Furnace without Replacing AC?

Can I replace my furnace without replacing the AC at the same time? Or do you need to replace both for the entire system to be fully functional? Is it necessary to stress about it now or worry about it later?

Your heating, ventilation, and air conditioning (HVAC) system is as complex as any other mechanical system on the planet. It has different parts, different components, different mechanisms that work together to make a perfectly dependable system. A furnace and an air conditioner are equally independent units and operate separately, but they serve one purpose. That is to keep homes, offices, and buildings justly comfortable for people to use and for businesses to operate.

As individual units that serve different purposes, oftentimes, people are presented with circumstances that will lead them to think whether both units need to be replaced at the same time.

Heating System Replacement | What Considerations to Make

Should you replace your furnace and AC together? Although many sales people will tell you, it will be more beneficial for you to replace both at the same time, this isn’t always the case. There are a lot of factors to consider before one can conclude a definite answer.

The heater (or the air handler) and the evaporator coil are both located indoors, and both are connected to the duct system. Meaning, if you are bound to replace the AC without replacing the furnace and coil, you are only replacing the AC’s outdoor unit. This action does not drastically change the overall functionality of the entire system. It will still work as intended and you can continue enjoying the comfort it brings.

But there are unforeseen situations such parts going loose or small but important components failing or breaking that can alter the profound performance of the system. Each component has a purpose; therefore, it has to be carefully matched to the rest of the system for maximum performance. If a new component with different operating features is added, it can put stress on the other parts and the system itself. That’s unnecessary stress you want to avoid for your comfort system.

The entire HVAC system will suffer if mismatched components are pieced together. And the following issues may arise.

Decreased system lifespan.

When incompatible components are added into the HVAC system, if significantly affects the efficiency and lifespan of the furnace or AC. It is a compromise that will not only result in costly heating repair services but will lead to a decrease in its value and functionality. With match equipment, you are rewarding yourself with a system performance that’s always at peak.

System lag and inefficiency.

What would happen if your outdoor unit is at 18 SEER (Seasonal Energy Efficiency Rating) while the indoor unit runs on an 8-10 SEER? A system mismatch? Yes, definitely. Since the outdoor and indoor units aren’t compatible and operate differently, the indoor unit can cause a lag. It wouldn’t be able to catch up to the newer unit. The other components will have to work harder and use more energy than needed.

Double installation cost.

When you focus on central heating replacement now, then wait a few years before replacing your AC, it means you’ll be paying for two separate installation costs when you can pay a discounted amount if both units are replaced together. That’s a lot of money you can effectively cut down especially when you can choose to save.

If your home heating stops working, you have to replace it right away.

The Technicalities of Heating and AC Installation

We’ve pointed out several things that support the idea of replacing the air conditioner and furnace at the same time. But here are other essential factors that also matter when buying a new unit.

How Old is the Heating and Cooling System?

The average lifespan of a quality furnace is 15 to 20 years while a good AC can last up 12 to 15 years. A carefully maintained HVAC system can live up to its average lifespan. Now, if both were installed together, technically they are of the same age. When the AC reaches its limit and is already at the end of its lifespan, it only means the furnace is nearing its time too. So, when you replace your AC, consider replacing both units. This will help you cost-cut on installation fees and maximize the return of your investment.

What is the SEER Rating?

Simple mat will say, the higher the SEER rating, the more efficient the unit is. High SEER also means less energy consumption while the system is running. The minimum SEER rating is 13 to 14 and above 16 SEER is highly efficient and commendable. Undeniably, a highly efficient system can cut energy usage nearly half of the energy consumption of old units with low SEER rating.

Low Price Doesn’t Mean Total Savings

Be careful with low priced ACs and furnaces. Low prices don’t always mean you’ll get the best value for your investment. Units with the highest efficiency often cost more up front, but the long-term savings per year will be a great deal for you. Just imagine having a highly capable and efficient system running for the entirety of its lifespan.

Also, the latest furnaces have stronger blowers and have the power to move more air throughout the house. With better airflow, indoor temperature is regulated effectively.

The Licensed HVAC Contractors ‘Near Me’

Over time, external factors can and will affect the functionality of the entire system. Dust, dirt, debris, and other foreign materials can cause build-up and clogging, and erosion on electrical connections. Rust is another threat that can cause damage that requires expensive repair service. A lot of things can happen when the system is not properly maintained.

You’ll have to hire the help of a good HVAC company to conduct regular maintenance on your heating and cooling services. Giving it extra care and attention that it deserves will secure its longevity and continued efficiency.
