AC Installation Cost in Richardson, TX (2026)

AC Installation Cost in Richardson, TX (2026)

For most Richardson homeowners replacing a central air conditioner in 2026, the installed cost lands somewhere between $7,000 and $16,000 depending on system size, whether you need a full HVAC overhaul or just the outdoor unit and coil, and which contractor you choose. Two factors pushed prices higher this year compared to 2024: new federal SEER2 minimum efficiency standards and the ongoing industry shift from R-410A to R-454B refrigerant, which together added roughly $500 to $1,000 to equipment costs across the DFW market. Getting three written quotes before signing anything remains the single most reliable way to avoid overpaying.

Best for Long-Term Accountability: Trotter Air and Houk Air Conditioning

Multi-Decade Contractors With Roots in North Texas

If the contractor still being in business ten years from now matters to you — and it should, given that most equipment warranties require documented professional service — Trotter Air Services and Houk Air Conditioning are worth a call. Trotter has operated continuously since 1970 and holds NATE certification under Texas HVAC license TACLA50795E, with a Plano headquarters on Jupiter Road that puts their crews inside Richardson in a short drive. Houk has served Richardson since 1962 and backs its work with a satisfaction guarantee, with NATE-certified technicians who are specifically trained to give honest assessments rather than upsell unnecessary equipment. Both are family-owned, which tends to mean the person whose name is on the truck has a reputational stake in the outcome.

Best for Straightforward Scheduling: Quick Solutions Air Conditioning & Heating

On-Time Service With Background-Checked Technicians

Quick Solutions has operated in Richardson since 2010 with a stated emphasis on punctuality and transparency. Their technicians are licensed, uniformed, and background-checked, which matters when you are letting someone into your attic or mechanical room. They cover a wide service corridor that includes Richardson, Allen, Frisco, Lake Highlands, Murphy, and Plano, so scheduling tends to be flexible. For homeowners who want a no-drama installation experience and are not necessarily looking for the oldest name in the business, Quick Solutions is a reasonable option to include in your quote comparison.

Best for Verified Online Reputation: LEX Air Conditioning

BBB A+ Rating and a Wide Collin-Dallas County Footprint

LEX Air’s independently verified BBB A+ rating covers a service area that includes Richardson, Plano, Garland, McKinney, and surrounding Collin and Dallas counties. Their main office at 901 Jupiter Road in Plano puts them close to most Richardson neighborhoods, and they advertise a 30-to-45-minute response window for most DFW locations. For homeowners who rely on third-party ratings as a screening tool before making calls, LEX Air’s publicly documented standing gives you a concrete data point rather than just a marketing claim.

Best for Combined HVAC and Plumbing Projects: Astar Air Conditioning & Plumbing

One Contractor for Two Trades

Astar (astardfw.com) is the only contractor in this comparison that explicitly bundles HVAC and plumbing services under one roof, and they offer 24/7 emergency response. In older Canyon Creek or Breckinridge Park-area homes where an AC replacement sometimes surfaces related issues — a corroded condensate drain line, an aging water heater sharing the same utility closet, gas line questions — having a single licensed contractor handle both trades can simplify permitting and coordination. Richardson requires a city permit for new HVAC system installations, and having one point of contact for inspections is a practical convenience.

2026 Price Ranges: What to Expect in Richardson

All figures below are ballpark estimates based on DFW market data and should be confirmed with written quotes from local contractors.

• AC repair (not replacement): $150 to $650 for most visits; typical repair lands around $350 to $450. Compressor or evaporator coil failures can exceed $1,500 to $2,500 and often make replacement the smarter financial move.
• Refrigerant top-off: R-410A runs roughly $50 to $90 per pound installed; a 2-to-4-pound recharge adds $100 to $360 to a service call.
• AC-only replacement (outdoor unit plus indoor coil, existing ducts reused): $7,000 to $13,000 installed for most Richardson homes. By tonnage: a 2.5-ton system runs approximately $4,800 to $7,500; a 3-ton system runs approximately $5,200 to $8,500.
• Full HVAC system replacement (AC, furnace, and air handler): $8,000 to $16,000 installed. DFW prices run 15 to 25 percent above the national average because Texas summers push air conditioners hard for eight to nine months a year.
• Ductwork replacement: Add $3,000 to $8,000 if your existing duct system needs to be replaced alongside the equipment.
• Repair-versus-replace threshold: If a repair quote on a system older than 10 to 12 years exceeds $2,500 to $4,000, price a full replacement before committing.

Available incentives in 2026:

• Oncor’s Home Energy Efficiency program offers $400 to $600 back on qualifying high-efficiency equipment. The program runs January through November, so late-summer installations still qualify if you act before the deadline.
• The federal Section 25C tax credit for HVAC equipment expired December 31, 2025, and is not available for 2026 purchases as of this writing.

Frequently Asked Questions

How much does a new AC system cost in Richardson, TX in 2026?

For an AC-only replacement using existing ductwork, most Richardson homeowners pay between $7,000 and $13,000 installed. A full system replacement including furnace and air handler typically runs $8,000 to $16,000. These are estimates; your actual cost depends on home size, system efficiency, and contractor pricing.

Do I need a permit to replace my AC in Richardson?

Yes. The City of Richardson requires a permit for new HVAC system installations and replacements. Your licensed contractor should pull the permit and schedule the required city inspection as part of the job; if a contractor tells you a permit is not necessary for a full system swap, that is a red flag.

Is it worth repairing or replacing an older AC unit in Richardson?

A common rule of thumb: if the repair quote exceeds $2,500 to $4,000 and the system is more than 10 to 12 years old, get a replacement quote before spending money on the repair. Richardson’s climate runs AC units hard, which accelerates wear compared to milder markets.

Can I get a rebate on a new AC in Richardson in 2026?

Oncor’s Home Energy Efficiency rebate program offers $400 to $600 on qualifying high-efficiency systems and is open through November 2026. Ask your contractor which equipment qualifies before you commit to a specific model.

How many quotes should I get before choosing an HVAC contractor in Richardson?

Three written quotes is the standard recommendation. Make sure each quote specifies the equipment model, system size in tons, SEER2 rating, warranty terms, and whether the permit and city inspection are included. Comparing quotes on those specifics is more useful than comparing bottom-line numbers alone.
