Split HVAC System in Your Home Can Lead to Major Cost Savings
At Gem Heating & Air Conditioning of Boise, we’re committed to helping homeowners stay comfortable and save money. One of the smartest investments you can make in your home comfort system is upgrading to a split HVAC system—especially here in the Boise area where temperature swings can be extreme. Let’s break down how a split HVAC system can help you cut costs, boost efficiency, and increase comfort.
What Is a Split HVAC System?
A split HVAC system consists of two main components:
- An indoor unit — the air handler and evaporator that circulates cool air inside your home
- An outdoor unit — the compressor/condenser that releases heat outside
Unlike traditional packaged systems, the split system allows each component to operate more efficiently, reducing wear and tear and saving you money.
Why Split Systems Save You Money
Here are some of the key ways a split HVAC system can reduce your costs:
1. Higher Energy Efficiency
Split systems typically offer much higher Energy Efficiency Ratios (EER) and Seasonal Energy Efficiency Ratios (SEER) compared to older systems. Modern units often reach SEER ratings of 16–26, meaning they use less electricity to deliver the same amount of cooling.
Typical savings: Homeowners may save 15–30% on cooling costs compared to older units. Depending on your current system and energy rates, that can be hundreds of dollars a year.
2. Zoned Comfort Means Less Waste
Split systems can offer zoning capabilities, where different areas of your home can be cooled independently. This helps eliminate wasted energy cooling rooms you aren’t using.
For example:
- Bedroom fans can stay off during the day
- Living room cooling can run slower at night
Over time, this adds up to real savings.
3. Longer System Lifespan
Because split systems are designed for efficiency and less strain, they often last longer with fewer repairs. That means lower maintenance costs over the life of your system.
What Does This Look Like in Dollars?
Here’s a simple breakdown of potential savings:
| System Type | Annual Cooling Costs | Estimated Savings |
|---|---|---|
| Older HVAC (10+ yrs) | $1,200 | — |
| New Split HVAC (SEER 18) | $840 | $360/year savings |
| Split with Zoning | $780 | $420/year savings |
Over a 10-year period, that’s $3,600 to $4,200 you could keep in your pocket—not including reduced maintenance and repair costs.
Increased Home Value
Energy efficiency is a major selling point for homebuyers. Adding a high-efficiency split HVAC system can increase your home’s value and make it more appealing when it’s time to sell.
