AC Replacement in Middle Tennessee. 10-year warranty included.
New high-efficiency system installed in one day, backed by a $500 guarantee if we miss your scheduled date.
When Should You Replace Your AC?
We won’t sell you a system you don’t need. However, at a certain point, repairing an old unit becomes more expensive than replacing it.
Our certified technicians help you evaluate your system’s health using these four critical factors:
- The Age Factor: Most air conditioners last 12 to 15 years. If yours is in that range, it’s statistically likely to face a major, expensive failure soon.
- Refrigerant Costs: If your system uses outdated R-22 (Freon), simple recharges are becoming unsustainably expensive.
- Frequency of Failure: If you’ve called for repairs more than once in the last two summers, your system is likely nearing total failure.
- Energy Efficiency: Modern SEER2 systems can slash your utility bills by up to 40% compared to units from just a decade ago.

What determines your final cost?
- Efficiency Rating (SEER2): Higher efficiency units cost more upfront but maximize your monthly utility savings.
- System Capacity: Larger homes require more powerful units to maintain comfort during a Tennessee heatwave.
- Home Infrastructure: If your existing electrical or ductwork needs upgrades to meet modern codes, this will impact the labor cost.

Frequently Asked Questions About AC Replacement
What is the "Rule of $5,000" for AC replacement?
The “Rule of $5,000” is a simple formula: multiply the age of your AC by the repair cost; if the total exceeds $5,000, you should replace the unit. For example, if a 10-year-old system needs a $600 repair ($6,000 total), the math suggests that investing in a new, high-efficiency unit is a smarter financial move than patching an aging system.
How long does it take to replace an air conditioner?
Most standard AC replacements are completed in a single day, typically taking between 6 and 10 hours. Our team arrives early to prep the site and does not leave until your new system is fully calibrated, the air is cool, and the workspace is spotless.
Will a new AC really lower my electric bill?
Yes, upgrading to a modern SEER2-rated unit can lower your summer cooling costs by 20% to 40%. Older systems work significantly harder to move heat, consuming more electricity. Modern high-efficiency units use advanced compressor technology to provide better cooling while using a fraction of the power.
Do you offer free estimates for AC replacement?
Yes, Petitt Heating & Cooling provides 100% free, no-obligation in-home estimates for all system replacements. We perform a full load calculation and ductwork “health check” to provide you with several customized options that fit your family’s budget and comfort goals.
Does a new system include a warranty?
Yes, every Petitt AC replacement is backed by a manufacturer’s parts warranty and our exclusive 10-Year Parts & Labor Warranty. We don’t just “swap boxes” and leave; we protect your investment for a full decade, ensuring that if any component fails, we make it right at no cost to you.
