It's 98 degrees in McKinney and your AC just stopped keeping up. The technician is standing in your living room telling you it might be time for a new system. Sound familiar? Before you sign anything, here's what you actually need to know.
The simplest way to decide: multiply your unit's age by the cost of the repair. If that number exceeds $5,000, replacement usually makes more financial sense.
💡 Don't let any contractor pressure you into a replacement without a second opinion. United National HVAC offers FREE diagnostics — we'll tell you exactly what's wrong and what your real options are.
Modern AC units run at 16–20 SEER2 efficiency ratings. If your current unit is a 10 SEER system from 2010, you could cut your cooling costs by 30–40% just by upgrading. Over 5 DFW summers, that difference adds up fast.
We hear it all the time — a homeowner gets quoted $8,000 for a full system replacement when all they actually needed was a $250 capacitor swap. Always get a second opinion before committing to a major replacement. It costs you nothing and can save you thousands.
If replacement is the right call, United National HVAC offers financing starting at just $49/mo. A full new system doesn't have to mean a financial emergency. We'll find a plan that fits your budget and get you back to comfortable the same day.
Use the 5,000 rule: multiply the unit's age by the repair cost. If the result exceeds $5,000, replacement is usually the smarter choice. A 10-year-old unit needing a $600 repair scores 6,000 — lean toward replacing it.
In the Dallas-Fort Worth area, AC units typically last 12–15 years due to extreme summer heat and high run time. Units that aren't maintained regularly may only last 10 years.
It depends on the repair cost. Minor repairs under $400 on a 10-year-old unit can make sense. But for a compressor replacement or refrigerant overhaul, a new unit with better efficiency will save you more money long term.
A new central AC system in DFW typically costs between $4,500 and $9,000 installed. United National HVAC offers financing starting at $49/mo to make it manageable.
Absolutely. Many homeowners are told they need full replacements when a targeted repair is all that's needed. United National HVAC offers free diagnostics so you always get an honest answer first.
