FAQs
When should I consider replacing my central air conditioner instead of repairing it?
Most Petros homeowners start looking at replacement when their system is 10–15 years old, requires frequent repairs, or suffers a major component failure such as a compressor or coil leak. If repair costs approach 30–40 % of the price of a new unit, or if the existing system uses the phased-out R-22 refrigerant, a replacement is usually the most cost-effective path. New equipment can cut cooling costs by 20–50 % compared with systems installed a decade ago, providing a quick payback even if the old unit still runs.
What size (tonnage) central AC unit do I need for my Petros home?
Proper sizing depends on more than just square footage; we perform a Manual J load calculation that accounts for Petros’ summer highs, humidity, insulation levels, window types, shade, and household occupancy. Undersized units run constantly and never cool well, while oversized units short-cycle, causing humidity issues and higher utility bills. After an in-home evaluation, we’ll recommend the exact tonnage and SEER2 rating that balances comfort, efficiency, and budget.
How energy-efficient are the new replacement systems you install?
We offer equipment ranging from the current federal minimum of 14.3 SEER2 up to 20 + SEER2 inverter-driven heat-pump and straight-cool models. Compared with an older 10 SEER unit, a 16 SEER2 system can reduce annual cooling costs by roughly 30 %. Advanced features such as variable-speed compressors, ECM indoor blowers, and smart thermostats improve part-load efficiency, humidity control, and overall comfort—particularly valuable in Petros’ warm, moist summers.
What is the average cost of a complete central air replacement in the Petros area?
For a typical 2- to 3-ton straight-cool AC with a matching indoor coil, installed cost starts around $4,500–$6,500. A high-efficiency two-stage or variable-speed heat-pump system with a new air handler can range from $7,500–$11,000. Price varies by capacity, efficiency rating, ductwork modifications, electrical upgrades, and IAQ add-ons such as media filters or UV lamps. We give upfront, itemized proposals so you can compare options side by side.
How long does it take to replace an existing central air conditioning system?
Most standard change-outs are completed in one full workday, including removal of the old condenser and coil, setting the new outdoor unit, brazing and evacuating the refrigerant lines, pressure testing, charging, and a final system start-up. If duct repairs, thermostat relocation, or electrical service upgrades are required, the project may extend to two days. We schedule all work at your convenience and provide temporary cooling solutions during peak-season emergencies.
Do you offer financing, rebates, or warranties on new AC replacements?
Yes. We partner with local credit unions and national lenders to provide 0 % APR promotional financing and low-monthly-payment plans (subject to credit approval). Many high-efficiency systems qualify for manufacturer rebates and the current federal Energy Efficient Home Improvement Tax Credit (up to 30 % of project cost, $2,000 maximum for qualifying heat pumps). All installations include a 10-year parts warranty from the manufacturer and our own 2-year labor warranty, with extended labor coverage available.
