We recommend servicing your HVAC system twice a year—once in the spring for your cooling system and again in the fall for your heating system. Routine maintenance improves efficiency, extends the life of your system, and helps catch small issues before they turn into expensive repairs.

👉 According to the U.S. Department of Energy, well-maintained HVAC systems can improve efficiency by up to 15%.

On average, HVAC systems last:

• Furnaces: 15–20 years
• Air Conditioners & Heat Pumps: 10–15 years
• Ductless Mini-Splits: 12–20 years

Factors such as usage, maintenance, climate, and unit quality play a major role. In East Tennessee's humid climate, systems may experience faster wear without proper upkeep.

📊 ENERGY STAR recommends replacing systems over 10 years old with high-efficiency models to save up to 20% on heating and cooling costs.

The proper size depends on square footage, ceiling height, insulation, number of occupants, windows, and usage. A “Manual J Load Calculation” should be performed to determine the right capacity—bigger is not always better.

Oversized units lead to short-cycling and inefficiency, while undersized systems will struggle to maintain comfort.

🏢 For example, a 2,000 sq. ft. home typically needs a system rated at 3 to 3.5 tons, but this varies by property.

High-efficiency systems:

• Reduce energy bills by up to 30%
• Improve indoor air quality
• Qualify for rebates and tax credits
• Operate more quietly and reliably

💸 Homeowners may save hundreds annually. The TVA EnergyRight program currently offers up to $2,800 in rebates> for qualifying upgrades in the Johnson City, TN area.

If your system:

• Is over 10–15 years old
• Needs frequent or costly repairs
• Struggles to maintain consistent temperatures
• Produces strange smells or noises
• Causes rising utility bills

…it may be time for a replacement. However, if the issue is isolated and your system is relatively new, repairs may be the better route.

🔧 Our team can diagnose your system and give honest advice—plus we apply TVA rebates to qualifying repairs as well.

SEER stands for Seasonal Energy Efficiency Ratio and measures the cooling efficiency of air conditioners and heat pumps.

• The higher the SEER, the more efficient the unit.
• The current minimum SEER rating for new units in Tennessee is 14 SEER, but modern systems can go up to 20+ SEER.

📉 A 16-SEER unit uses about 13% less energy than a 14-SEER model. Over 10 years, that can equal thousands in savings.
