How do I know if I need AC replacement or just repairs?

Age and repair frequency tell the story. If your unit is over 10–12 years old and needing repairs multiple times per year, replacement usually makes more financial sense. Constantly rising energy bills despite regular maintenance also signal an aging system losing efficiency. Major component failures like compressor or evaporator coil problems often cost more to fix than the repair is worth on older units. An assessment looks at repair costs versus remaining system life to give you an honest recommendation.

What size AC unit does my Old Jefferson home need?

Proper sizing requires calculating your home’s cooling load, not just square footage. Louisiana’s climate demands systems that handle both temperature and humidity effectively. Factors include insulation levels, window placement, ceiling height, and how much sun exposure your home gets. Oversized units short-cycle and waste energy while failing to remove humidity. Undersized systems run constantly and never achieve comfortable temperatures. Load calculations verify your new system matches your home’s specific cooling requirements for maximum efficiency and comfort.

How long does AC replacement take in Old Jefferson?

Most residential AC replacements take one full day for straightforward installations. More complex jobs involving ductwork modifications, electrical upgrades, or difficult access areas might require two days. Weather can impact timeline since Louisiana’s afternoon storms sometimes delay outdoor work. The process includes removing old equipment, installing new indoor and outdoor units, connecting refrigerant lines, testing system operation, and cleanup. Contractors schedule installations to minimize disruption and verify proper testing before considering the job complete.

What's the cost difference between AC repair and replacement?

Major repairs on older systems often cost 30–50% of replacement cost but only extend system life 1–2 years. Compressor replacement typically runs $1,500–$2,500 on units over 8 years old, while new system installation provides 10–15 years of dependable service. Energy savings from modern efficiency often offset replacement costs within 3–5 years through lower monthly bills. Consider total cost of ownership—older systems require more frequent service calls, higher energy consumption, and eventual replacement anyway. Honest contractors help you evaluate repair costs against remaining system value.

Do new AC units really save money on energy bills?

Modern high-efficiency units use significantly less electricity than systems installed even 5–7 years ago. SEER ratings of 16+ versus older 10–12 SEER systems can reduce cooling costs by 30–40% in Louisiana’s climate. Variable speed technology adjusts output to actual cooling needs instead of running full blast constantly. Better humidity control means comfortable temperatures at higher thermostat settings. Most Old Jefferson homeowners see noticeable bill reductions within the first month of operation, with savings increasing as energy costs rise over time.

What warranty protection comes with new AC installation?

New systems typically include manufacturer warranties covering parts for 5–10 years, with compressors often warranted longer. Installation warranties cover workmanship and verify any installation-related issues get resolved quickly. Registration requirements and proper installation procedures affect warranty validity, so contractors handle documentation correctly. Extended warranty options provide additional protection beyond standard coverage. Quality installation prevents most warranty claims by verification proper system operation from day one. Local contractors remain available for warranty service throughout the coverage period.
