Best Time to Replace Furnace and Air Conditioner Systems: And Should You?

When it comes to keeping your home comfortable, having a reliable furnace and air conditioner system is essential. But over time, these systems can become outdated and inefficient, leading to higher energy bills and potential breakdowns. Or in some cases, one of the components of the system already has broken down and you’re wondering whether you should just replace the component that is broken or if you should opt for an entirely new HVAC system for your home. 

Knowing when to replace your furnace and air conditioner system can help you save money in the long run while ensuring that your home stays comfortable all year round. And choosing the right time to do so can ensure your life isn’t disrupting much. In this article, we’ll discuss the best time to replace your furnace and air conditioner system so you can make an informed decision about when it’s time for an upgrade. We’ll also include some of the features you should consider when replacing parts or your complete HVAC system. 

Should You Replace Your Complete HVAC System at the Same Time?

The short answer is yes. It’s generally best to replace both your furnace and air conditioner system at the same time because it’s usually less expensive. This ensures that you get the most efficient performance from your HVAC system, as well as the longest lifespan for both components. Additionally, replacing both components at once can save you money in the long run since it eliminates the need to purchase two separate systems. 

Factors that can Influence Your Decision

When deciding whether to replace your furnace and air conditioner system, there are a few factors you should consider. These include the age of your current system, the efficiency of the system, and any repairs that may be needed. 

Age: The average lifespan of a furnace and air conditioner system is around 15-20 years depending on the quality of the initial system installation. If your system is older than this, it’s likely time to replace it. Additionally, if your system is more than 10 years old, you may want to consider replacing it even if it’s still working properly. This is because newer systems are much more energy efficient and can save you money on your monthly energy bills. 

Efficiency: If your system isn’t running as efficiently as it used to, or if you’re noticing higher and higher energy bills month over month, then it may be time to replace your system. Newer systems are much more efficient and can help you save money in the long run. 

Repairs: If you’re noticing that your system needs frequent repairs, then it’s probably time to replace it. Frequent repairs can be costly and can indicate that your system is nearing the end of its lifespan. Additionally, if you’re having trouble finding replacement parts for your system, then it may be time to upgrade. 

Temperature During Replacement

One thing you’ll need to consider when getting your HVAC system replaced is the temperature and weather outside. This option is mainly for people who are replacing their systems not due to a breakdown. Don’t wait until the coldest week of the year or during the middle of summer when it’s hottest. Sometime in the Fall or Spring is usually best and also it’s a great time to look for discounts on some HVAC system simply because of the season. For example, air conditioning may be cheaper in the fall, while a furnace is cheaper during the spring. 

Current Energy Bills

You’ll also need to consider your current energy bills and just how much impact your heating and cooling system has on that bill. Many of the modern heating and cooling systems have features which can help them be more efficient. Additionally, you can opt for upgrades like zoned HVAC systems, programmable thermostats, and more.

Does Your System Require Service More Often Than it Should?

Are you constantly putting money into your old heating or cooling system? If so, it may be time to consider getting it replaced. Older systems require more frequent service and repairs, which can be costly in the long run.

Types of HVAC Systems

There are many different types of HVAC systems on the market today. And while these systems are different in different areas of the country depending on how cold or hot the area gets, they sometimes use the same components such as ducting and thermostats even though they are not connected. 

Complete Heating and Cooling Systems

A complete HVAC system is typically called a package unit. This type of system is usually used in more moderate weather climates. These types of systems can also be called heat pumps, gas packs, central air conditioner, or freon/electric system. A split air conditioner can also be a complete system as long as heating and cooling functions are included. And while there are differences in these systems the main point is that the heating and cooling systems is contained within one unit. Most complete systems have lower overall energy costs when compared to separate units.

Separate HVAC Systems

The other type of HVAC system is a separate HVAC system. This can mean you have an A/C system and a furnace installed in your home. Some split-systems have a condenser and evaporator coils located in separate units but they are connected which makes them more of a complete system. Mini duct-less air conditioners with a heat pump are these types of systems. Most times, the energy costs of 2 different systems are more expensive.

Reasons Why You Should Not Replace Your HVAC Systems at the Same Time

Replacing both your furnace and air conditioner at the same time can be expensive. It’s best to replace them separately so you can spread out the cost over a longer period of time. Additionally, if one system is still working properly, then there’s no need to replace it. You should only replace it when it needs to be replaced. 

Reasons Why You Should Replace Your HVAC Systems at the Same Time

Replacing both your furnace and air conditioner at the same time can be beneficial in some cases. Most importantly because you can decrease your overall energy costs. For example, if you have an older system that is inefficient, replacing both systems at the same time can help you save money on energy bills. Additionally, it’s easier to install a complete HVAC system than two separate systems. This means less labor costs and fewer installation headaches.

And if you are considering financing your new HVAC system, you can spread the cost of the entire HVAC system out over time so it’s not such an immediate expense. Since most systems will last for more than 10 years it can give you peace of mind for a long time. You may also be able to take advantages of rebates from some manufacturers as well when you replace your heating unit and air conditioning systems at the same time. 

When Replacing Your Air Conditioner or Furnace Consider Comfort and Energy Efficiency

When replacing your air conditioner or furnace, it’s important to consider both comfort and energy efficiency. Look for an HVAC system that is Energy Star certified and has a high SEER rating. This will help ensure you get the most out of your new system. Additionally, make sure you choose a system that is sized correctly for your home. A unit that is too small won’t be able to keep your home comfortable, and a unit that is too large will waste energy.

Consider Indoor Air Quality as Well

Finally, when replacing your HVAC system, you should also consider indoor air quality for your home. Look for a system that has features such as air filtration and humidity control. This will help ensure the air in your home is clean and comfortable. 

Look for Specials and Deals on HVAC Equipment

When replacing your HVAC system, it’s also important to look for sales and deals on the equipment you have an idea about purchasing. Many manufacturers offer discounts and rebates on their products, so make sure you take advantage of these offers when possible. Some localities also offer rebates for installing an efficient furnace or modern air conditioner. Additionally, some contractors may offer special financing options or other incentives to help you save money.  

Replacing Air Conditioning During Winter and Furnace During Summer

Finally, it’s best to replace your air conditioner during the winter and your furnace during the summer when demand is low. This is because it’s easier to install a new system when the weather is different than the system you are installing. Additionally, you can save money on energy bills by replacing your air conditioner in the winter and your furnace in the summer since in this situation, you won’t be using them at that time. 

This can ensure you remain comfortable in your home as well. And if you do decide to replace both your old HVAC systems with a newer high-efficiency air conditioner and furnace, your utility bills should come down year round.
