What Buyers Pay to Replace a Lennox TXV Valve in Typical Homes
Most homeowners pay $250-$850 to replace a Lennox TXV valve, with an average around $450 for a standard single-family split system. Average assumes 2-3 ton Lennox air handler or coil, standard access, and certified HVAC technician handling refrigerant.
Part-only prices run $85-$350 for OEM or compatible valves depending on model and orifice size; labor generally adds $125-$500 based on time and complexity.
Breakdown of Quote Parts: Materials, Labor, Equipment, and Disposal
| Materials | Labor | Equipment | Delivery/Disposal |
|---|---|---|---|
| $85-$350 (TXV valve, fittings, braze rods) | $125-$500 (1-4 hours at $75-$125/hour) | $60-$180 (vacuum pump, manifold gauges) | $0-$75 (old part disposal, refrigerant recovery fees) |
Typical contractor quote itemizes parts, labor hours, vacuum/pump rental use, and refrigerant recharge.
How Specific Valve Models and System Tonnage Change the Final Price
Higher tonnage Lennox coils need larger orifice TXVs or special adaptation kits, increasing part cost. Expect part prices: 1.5-2.5 ton $85-$160; 3-4 ton $150-$260; 5+ ton or specialty models $220-$350.
Labor rises if the coil is in an awkward location: add 1-3 extra hours for rooftop units or tightly tucked attics (add $75-$375).

Site Conditions That Drive Up Replacement Costs
Restricted access, corroded fittings, or need to remove the evaporator coil for access are common cost drivers. Examples: easily accessible indoor coil—1-2 hours; rooftop/attic coil—2-5 hours and potential crane/lift fees.
- Corroded joints requiring cutting and re-brazing: +$75-$200.
- System needing full evacuation and triple evacuation/testing: +$60-$180 in equipment/time.
- R-22 systems may require recovery and special handling: +$100-$300 for refrigerant.
Practical Ways to Lower Lennox TXV Replacement Price
Homeowners can reduce cost by confirming model number before the call and choosing compatible aftermarket valves when acceptable. Buying the valve ahead can save $25-$100 against dealer markup, but confirm return policy and compatibility.
- Schedule service in shoulder seasons to avoid emergency or peak pricing.
- Bundle TXV replacement with nearby planned HVAC work to reduce trip fees.
- Provide clear access and remove attic obstacles to shorten labor time.
Regional Price Differences and What to Expect Across the U.S.
Labor and markup vary by region: urban/coastal areas often run 10%-30% higher than Midwest/rural markets. Typical regional ranges: Midwest $350 avg; Southeast $400 avg; Northeast/West Coast $450-$550 avg.
Contractor hourly rates: $75-$95 in low-cost areas, $95-$125 in high-cost metro areas.
Common Add-Ons, Diagnostics, and Real Quote Examples
Diagnostic fees, refrigerant recharge, and brazing work commonly appear as extras. Example quotes illustrate real scenarios to help judge estimates.
| Example | Specs | Labor Hrs | Parts | Total |
|---|---|---|---|---|
| Quick Replace | 2-ton indoor coil, easy access | 1.0 | $120 | $250 |
| Standard Job | 3-ton, attic coil, R-410A | 2.5 | $180 | $475 |
| Complex Job | 5-ton rooftop, corroded fittings | 4.0 | $300 | $820 |
