How Long Does an AC Unit Last in Texas?

How much does a new AC cost in Central Texas?
A new central AC system in Central Texas typically costs $5,800–$13,500 installed, depending on size (2–5 tons), efficiency (14–25+ SEER), and brand tier. Entry-level 14 SEER systems start around $5,800 for a 3-ton unit, while premium 20+ SEER systems with smart thermostats run $10,000–$13,500. We offer financing from $89/month. Use our free HVAC Cost Estimator for a personalized Good/Better/Best quote.

10

How long does an AC last in Texas?
Central air conditioners in Texas typically last 12–15 years, shorter than the national average of 15–20 years due to our extreme heat and 8–9 month cooling season. Heat pumps average 10–14 years, furnaces 15–25 years, and mini-splits 12–20 years. Regular maintenance can add 3–5 years to your system's life. Use our free HVAC Age Decoder to check your system's age and remaining lifespan.

11

What SEER rating should I choose for my new AC?
For Central Texas, we recommend at least 16 SEER for good value or 18–20+ SEER if you plan to stay in your home long-term. The minimum federal standard is now 14.3 SEER2 (roughly 15 SEER) for southern states. Higher SEER means lower energy bills — upgrading from 10 to 16 SEER saves approximately 37% on cooling costs. Our Energy Savings Calculator can project your exact savings and payback period.

12

How do I know if my AC needs refrigerant?
Signs your AC may need refrigerant include: warm air from vents when cooling is on, ice forming on the refrigerant lines or evaporator coil, hissing or bubbling sounds near the outdoor unit, and higher-than-normal electric bills. A properly installed AC system should never need a recharge — if it's low on refrigerant, there's a leak that needs professional repair first. Use our Refrigerant Cost Estimator to see what a recharge might cost.

13

Should I repair or replace my AC?
Use the 50% rule: if the repair cost exceeds 50% of the replacement cost, replace. Also consider age — if your system is over 10 years old and needs a major repair ($1,000+), replacement usually makes more financial sense. If your system uses R-22 refrigerant (banned in 2020), replacement is strongly recommended regardless of repair cost due to skyrocketing refrigerant prices. Our Repair or Replace Calculator gives you a data-driven recommendation.

14

What size AC do I need for my house?
As a rough guide, Central Texas homes need about 1 ton of cooling per 500–600 square feet — so a 2,000 sq ft home typically needs a 3.5–4 ton system. However, proper sizing depends on insulation, windows, attic ductwork, ceiling height, and sun exposure. Oversizing is the #1 mistake — it causes short cycling, poor humidity control, and higher bills. Texas building code requires a Manual J calculation for new installs. Try our BTU Calculator for a free estimate, then call us for a professional in-home assessment.

15

How often should I change my air filter in Texas?
In Central Texas, change standard 1-inch filters every 30–60 days during peak cooling season (May–September) and every 60–90 days the rest of the year. Deep-pleated 4-inch filters can last 6–12 months. Homes with pets, allergies, or during cedar season (December–February) should change more frequently. A dirty filter is the #1 cause of AC problems — it restricts airflow, increases energy use by 5–15%, and can freeze the evaporator coil. Our Filter Size Finder helps you find the right replacement.

16

Why is my summer electric bill so high?
In Central Texas, air conditioning accounts for 50–60% of summer electric bills. A 3-ton AC running 10 hours daily at $0.13/kWh costs roughly $100/month just for cooling. Common causes of unusually high bills include: a dirty filter (5–15% penalty), an aging low-SEER system, a refrigerant leak causing the system to run constantly, thermostat set too low, or poor insulation. Use our Energy Cost Calculator to see what your AC should cost to run, and our Thermostat Savings Calculator to find easy savings.

17

Do you offer financing for HVAC installation?
Yes, we offer flexible financing options for new HVAC installations. Depending on credit approval, options include low monthly payments starting from $89/month, promotional 0% APR periods, and terms up to 120 months. Financing makes it possible to choose a higher-efficiency system that saves more on energy bills over time. Use our HVAC Cost Estimator to see monthly payment estimates for Good/Better/Best system tiers.

18

What's the difference between R-22, R-410A, and R-32 refrigerant?
R-22 (Freon) was the standard for decades but was banned in 2020 due to ozone depletion — only reclaimed supply exists, making recharges extremely expensive ($150–$250/lb). R-410A (Puron) has been the standard since 2010 and is now being phased down under the AIM Act due to high global warming potential. R-32 and R-454B are the newest generation — lower environmental impact, slightly better efficiency, and lower charge amounts. If your system uses R-22, replacement is strongly recommended. See our Refrigerant Cost Estimator for current pricing.

19

What maintenance does an HVAC system need?
HVAC systems need both DIY and professional maintenance. DIY tasks include changing the air filter monthly during heavy use, keeping the outdoor unit clear of debris, and flushing the condensate drain line quarterly with vinegar. Professional tune-ups should be done twice per year — AC in spring (March–April) and heating in fall (September–October). A professional tune-up includes refrigerant check, electrical testing, coil cleaning, and safety inspection. Regular maintenance prevents 90% of breakdowns and extends system life 3–5 years. Our Maintenance Checklist gives you a month-by-month schedule.

20
