Quick wins are great, but if your system still underperforms, you’ll want a technician who can diagnose accurately and prevent repeat failures.
Let’s get specific about what fails, why it fails, and how it’s fixed. Knowing the common culprits helps you ask better questions and avoid unnecessary costs.
Bad capacitor
Symptoms: AC won’t start, hums but doesn’t run, intermittent shutdowns.
Fix: Replace with a correctly sized, high-quality capacitor. Quick, affordable repair.
Failed contactor
Symptoms: Outdoor unit won’t start or won’t shut off.
Fix: Replace the contactor; inspect related wiring for heat damage.
Dirty coils (evaporator or condenser)
Symptoms: Poor cooling, high energy bills, short cycling, freezing.
Fix: Professional cleaning, plus filter and airflow checks to prevent recurrence.
Low refrigerant or leak
Symptoms: Weak cooling, long runtime, ice on lines, bubbling/gurgling sounds.
Fix: Leak detection (dye, electronic sniffer, nitrogen pressure test), repair, and recharge to manufacturer spec. Avoid “top-offs” without leak repair.
Blower motor issues
Symptoms: Weak airflow, no airflow, burning smell or squealing.
Fix: Replace motor or capacitor, balance blower wheel, confirm static pressure.
Faulty control board or sensors
Symptoms: Random shutdowns, error codes, weird behavior after storms.
Fix: Diagnostics with meter and manufacturer literature; replace components and update firmware if applicable.
Ductwork problems
Symptoms: Hot/cold spots, high humidity, dust, whistling.
Fix: Seal leaks, add insulation, correct sizing, balance registers. Sometimes duct redesign is cost-effective.
Thermostat mismatch
Symptoms: Short cycling, uneven cooling, poor dehumidification.
Fix: Install a compatible, properly configured thermostat and calibrate settings.
Condensate backup
Symptoms: Water around the air handler, system shuts off.
Fix: Clear line, install cleanout and float switch, recommend maintenance.
Ask for a written diagnosis and parts list. A trustworthy HVAC contractor explains the “why,” not just the “what.”
Replacing an AC or heat pump is a big decision. Use this framework to evaluate your options with clarity.
Age of system
10–12 years: Consider replacement planning.
12–15 years: Replacement often makes financial sense, especially after expensive failures.
15+ years: New system yields reliability, better comfort, and energy savings.
Repair cost ratio
A common rule: If the repair exceeds 30–40% of replacement cost and the unit is older than 10 years, replacement may be smarter.
If the compressor fails out-of-warranty, replacement is often the sound choice.
Efficiency gap
New units offer higher SEER2 ratings and better humidity control.
Monthly savings can be substantial in humid climates; over 10 years, the difference adds up.
Comfort and IAQ goals
Need better humidity control, quieter operation, or improved filtration? Modern systems excel here.
Refrigerant type
Older R-22 systems are costly to maintain and not environmentally friendly. If you’re still on R-22, replacement is prudent.
Ductwork compatibility
Sometimes replacing the air handler and outdoor unit without addressing poor ductwork results in mediocre performance. Budget for duct improvements if needed.
Warranty considerations
New systems come with manufacturer warranties; registering promptly and maintaining the unit protects your investment.
Always ask your contractor for a side-by-side cost-of-ownership comparison. Include energy savings, repair projections, and available incentives.
Great equipment installed poorly will underperform. Here’s what a high-quality air conditioning replacement or hvac installation should include:
When your installer follows these steps, you’re set up for long-term comfort and lower ownership costs.
Even in Louisiana, cold snaps can strain older furnaces or heat pumps. If your system sputters when the temps dip, you’ll want to know the basics:
Furnace repair vs. furnace replacement
Heat exchangers, control boards, and inducer motors are major cost drivers.
If the furnace is over 15 years old and safety is a concern (e.g., cracks in the heat exchanger), replacement is the right call.
Heater installation basics
Correct gas line sizing, venting, and combustion air are non-negotiable for safety.
For heat pumps, auxiliary heat (electric strips or gas backup) should be sized for local winter design temperatures.
Heater repair signs
Frequent short cycling, odd smells, delayed ignition, or rising utility bills.
Carbon monoxide alarms must be tested regularly; if one trips, shut down equipment and ventilate.
Smart thermostats in winter
Avoid excessive night setbacks with heat pumps to reduce reliance on auxiliary heat.
Use adaptive recovery features to pre-warm efficiently.
Keep your heating system on the same maintenance schedule as your AC. A well-tuned heater is safer, quieter, and cheaper to run.
Routine hvac maintenance is the single best way to reduce surprise breakdowns and keep utility bills in check. A comprehensive tune-up twice a year (spring and fall) typically includes:
Benefits you’ll notice:
Pro tip: Ask your contractor to record baseline performance numbers. Trends in static pressure, temperature split, and amperage can reveal issues before they become expensive.
In a humid climate, comfort isn’t just about temperature. It’s about how much moisture your system can pull from the air. High humidity makes 76°F feel sticky, while balanced humidity delivers comfort even at slightly higher temperatures—saving energy.
Consider these IAQ and humidity tools:
Ask your contractor to set up your thermostat for dehumidification control. Some smart thermostats can lower blower speed or extend cooling cycles to keep relative humidity in check.
Every house is different, but Baton Rouge homeowners can expect these ballpark figures:
Common repairs
Capacitor: Low cost, fast fix.
Contactor: Low to moderate cost.
Blower motor: Moderate to higher, depending on ECM vs. PSC.
Refrigerant leak repair and recharge: Moderate to higher; depends on leak location and refrigerant type.
Control board: Moderate to higher, varies by brand and model.
Replacement projects
Split AC or heat pump replacement: Pricing varies based on efficiency (SEER2), size (tonnage), staging (single vs. variable), and ductwork updates.
Add-ons like smart thermostats, whole-home dehumidifiers, and improved filtration increase upfront cost but can repay through comfort and energy savings.
Factors influencing price:
Always request a written scope, line-item pricing, and performance specs. The cheapest quote may cut corners you can’t see.
Here’s where smart Baton Rouge homeowners get ahead of the heat:
Ask your contractor to model estimated savings for your home. When numbers are specific and local, you can invest with confidence.
Transparency reduces stress. Here’s a typical flow:
Good contractors treat your home with respect—drop cloths, shoe covers, and a tidy workspace.
Don’t roll the dice on comfort. Use this checklist to select a dependable pro:
Clarity up front prevents headaches later.
This isn’t glamorous, but it’s vital:
Ask for documentation. A professional is proud to show their compliance.

Why is my AC running but not cooling?
Likely causes include a dirty filter, low refrigerant due to a leak, dirty coils, or a failing compressor. Replace the filter first. If airflow is fine, call for a diagnostic to check refrigerant charge and component health.
Should I repair or replace my 12-year-old AC?
If repairs cost more than 30–40% of a new unit and efficiency is outdated, replacement often yields better comfort and lower bills. Request a cost-of-ownership comparison.
How often should I service my HVAC system?
Twice a year: cooling tune-up in spring, heating tune-up in fall. Check filters monthly in summer.
What size AC do I need for my home?
Only a Manual J load calculation can answer that accurately. Square-foot rules of thumb risk oversizing or undersizing.
Can high humidity mean my AC is oversized?
Yes. Oversized systems short cycle and don’t run long enough to dehumidify. Variable-capacity systems and correct sizing solve this.
Scenario 1: Mid-summer no-cool call
Diagnosis: Failed capacitor and dirty outdoor coil.
Fix: Replace capacitor, clean condenser, verify refrigerant subcooling and superheat.
Outcome: Same-day restore, improved temperature split, lower amperage draw.
Scenario 2: Chronic humidity issues
Diagnosis: Oversized 5-ton unit on a home needing 3.5 tons, leaky return duct.
Fix: Right-size to variable-capacity 3.5-ton system, seal duct leaks, recalibrate thermostat humidity setpoint.
Outcome: RH levels drop from 65% to 50%, energy savings of 20% measured on bills.
Scenario 3: Aging furnace with safety concerns
Diagnosis: Cracked heat exchanger; CO readings near alarm threshold.
Fix: Furnace replacement with proper venting, gas line check, and CO monitor upgrade.
Outcome: Safe, efficient heat and lower winter bills.
