Signs You Need a New HVAC System
If you're unsure whether to repair or replace your current system, look for these common indicators:
Age: Most residential HVAC systems last 10–15 years. Systems older than that typically lose efficiency and are more prone to breakdowns.
Rising energy bills: A steady increase in heating and cooling costs, without a change in usage, often points to a system working harder than it should.
Frequent repairs: If you're calling for repairs multiple times a year, replacement can be more cost-effective long-term.
Uneven heating or cooling: Rooms that are noticeably warmer or cooler than others can indicate a system that's undersized, poorly installed, or failing.
Unusual noise or odors: Grinding, banging, or a burning smell are signs a system needs professional evaluation.
R-22 refrigerant systems: Older systems that use R-22 (Freon) are increasingly expensive to service since R-22 production has been phased out in the U.S.
The HVAC Installation Process
A typical HVAC installation includes an in-home assessment, system sizing, equipment selection, removal of the old unit, installation, and a final testing and walkthrough — usually completed in one day for standard systems.
Free in-home consultation — A technician evaluates your home's square footage, insulation, ductwork, and existing equipment.
System recommendation — Based on load calculations, not just the size of your old unit.
Written estimate — Upfront pricing before any work begins.
Removal of old equipment — Included at no additional cost.
Installation — New equipment is installed, connected, and tested.
Final walkthrough — Technicians confirm the system is operating correctly and review maintenance and warranty details with the homeowner.
Most standard installations are completed within one day. Installations that require ductwork modifications or electrical upgrades may take longer.
How to Size a New HVAC System (BTUs Explained)
BTU (British Thermal Unit) capacity determines how much heating or cooling power an HVAC system can produce. A system that's too small won't keep up with demand; a system that's too large will cycle on and off too frequently, wasting energy and wearing out components faster.Capacity is one of the most commonly underestimated factors in HVAC installation. A properly sized system accounts for:
Insulation quality
Existing ductwork condition
Local climate (East Tennessee's humid summers and cold winter snaps both factor into sizing)
Our technicians calculate BTU requirements during the free in-home consultation rather than simply matching the size of the unit being replaced, which is a common shortcut that leads to poor performance.
SEER2 Ratings Explained
SEER2 (Seasonal Energy Efficiency Ratio 2) measures how efficiently an air conditioner or heat pump cools your home over a typical season. Higher SEER2 ratings mean lower energy costs. As Trane-certified dealers, we install systems ranging from 13.4 to 21.5 SEER2.
When shopping for a new air conditioner, look for the highest SEER2 rating that fits your budget. This number reflects the ratio of cooling output to energy consumed over a season — the higher the number, the more efficiently the unit runs. SEER2 replaced the original SEER metric in 2023 with updated testing procedures that better reflect real-world conditions like ductwork static pressure.
SEER2 Range
General Efficiency Level
13.4–14.3
Minimum efficiency standard (as of current DOE requirements)
15–17
Mid-tier efficiency, solid value for most homes
18–21.5
High-efficiency, lower long-term operating costs

AFUE Ratings Explained
AFUE (Annual Fuel Utilization Efficiency) measures what percentage of fuel a furnace converts into usable heat. The U.S. Department of Energy considers furnaces with high AFUE ratings "high-efficiency." Electric furnaces typically have AFUE ratings between 95% and 100%, since they convert nearly all their electricity into heat.
If you're upgrading a heating system, the AFUE rating tells you how much of the fuel you're paying for actually becomes heat in your home, versus being lost as exhaust. As Trane-certified dealers, we offer furnace options that meet the DOE's high-efficiency standards.

MERV Ratings and Indoor Air Quality
MERV (Minimum Efficiency Reporting Value) rates how effectively an air filter removes particles from the air, on a scale of 1–16. Higher MERV ratings capture smaller particles but can also restrict airflow, so filter choice should balance air quality goals with your system's capacity to pull air through it.
A higher MERV rating isn't automatically the right choice for every home. Filters rated too high for a given system can restrict airflow, forcing the HVAC unit to work harder and reducing efficiency. Our technicians can recommend a MERV rating that matches both your indoor air quality goals and your system's specifications.
