Should I Repair or Replace My AC in Lubbock?

Whether you repair or replace your air conditioner depends on your system’s age, the type of problem, and how much the fix will cost compared to a new installation. A common guideline is the 50% rule: if your AC repair cost is 50% or more of a replacement, it’s usually smarter to replace.

When It’s Cheaper to Repair Your AC

Your AC Unit is Under 10 Years Old

The average lifespan of a central AC unit is 12-15 years (Air Conditioning, Heating, and Refrigeration Institute, Air-Conditioning and Heat Pump Efficiency 101). If your system is younger and still under warranty, repair is almost always the better option.

The Issue Is Minor

Not every AC problem means it’s time for a major investment. Many common issues can be fixed quickly and affordably. Issues like clogged drain lines, capacitor replacements, or thermostat problems are simple fixes that almost always lead to repair being the smarter choice.

The Repair is Less Than 30%-40% of a New AC Cost

When the repair is relatively cheap to do, it doesn’t make financial sense to replace the entire unit. A new AC unit costs, on average, between $3,400- $8,400 in Texas (Angi, How Much Does AC Replacement Cost? [2025 Data]). The cost will vary from home to home, based on factors like home size and the type of unit. If a repair is only a fraction of the cost, it’s usually best to repair and extend AC’s lifespan.

Repairs Are Rare

Occasional service calls are normal, especially in Lubbock’s hot climate where AC systems work hard. But if your service calls are few and far between, it’s a good sign that your AC is still reliable. Paying for a one-time repair is far cheaper than replacing a unit that otherwise has years of service left.

When It’s Cheaper to Replace Your AC

Your AC Unit is 12-15+ Years Old

Once your AC is over 10 years old, it reaches the end of its expected lifespan. Even if you repair it now, chances are another issue will pop up soon. A replacement gives you peace of mind and avoids pouring money into a unit that’s running on borrowed time.

The Repair Costs 40%-50%+ of a New AC Unit

Sometimes, even if the AC is relatively new, major repairs are needed. At a certain point, it becomes the cheaper option to replace the unit—think of it like “totaling” a car. Some major repairs that may lead to replacement instead include compressor coil failures, evaporator coil failures, or blower motor failures.

Energy Bills are Rising, Even After Repairs

Energy costs can significantly add up over time. If your unit keeps driving up bills even after repairs, it may be undersized, outdated, or simply worn out. A replacement, especially with a high-efficiency unit, can cut energy costs significantly—up to $140 annually when choosing an ENERGY STAR® certified unit (ENERGY STAR, Heat & Cool Efficiently).

Your System Uses Outdated Refrigerant

Older systems use refrigerant that is harder to find because it gets phased out by newer products. This scarcity leads to an increase in price, so every refrigerant repair will be more expensive due to the refrigerant.

Common AC Problems: Repair or Replace?

AC Not Blowing Cold Air

Cause: Dirty air filter, low refrigerant, frozen coils, or electrical issue.

Repair or Replace? If the system is under 10 years old and refrigerant levels can be corrected or filters replaced, repair is best. If the compressor is failing or the unit is 12+ years old, replacement may be more cost-effective.

AC Leaking Water

Cause: Clogged condensate drain line, frozen evaporator coils, or broken pump.

Repair or Replace? Typically, these issues call for repair, since drain line cleanouts or coil servicing are routine. Replacement is only considered if the unit has chronic coil damage or advanced age.

AC Short Cycling (Turning On/Off Frequently)

Cause: Oversized unit, dirty air filter, thermostat issues, or low refrigerant.

Repair or Replace? Repairs are common (filter change, thermostat calibration). If the unit is fundamentally the wrong size for the home, replacement may be the only fix.

AC Not Turning On

Cause: Tripped breaker, failed capacitor, thermostat malfunction, or motor failure.

Repair or Replace? Repairs are common for electrical components. Replacement is considered if major parts (like blower motor or compressor) fail on an older system.

AC Increasing Energy Bills

Cause: Reduced efficiency from dirty coils, aging parts, or refrigerant leaks.

Repair or Replace? Tune-ups and cleaning often solve this. If the system is older and still causing rising costs, upgrading to a high-efficiency system will save more in the long run.
