Daikin 15.2 SEER2 Heat Pump Installation in Southlake, TX (76092)

A High-Efficiency Upgrade by Greentech Engineering Heating & Air Conditioning

Greentech Engineering Heating & Air Conditioning recently completed a full Daikin heat pump system replacement for a single-family homeowner in Southlake, TX 76092. The project involved upgrading an older 2-ton system to a properly sized 3-ton Daikin 15.2 SEER2 high-efficiency split heat pump system, delivering improved comfort, quieter operation, and long-term energy savings tailored to North Texas conditions.

As a Daikin Comfort Pro dealer, our team follows strict engineering and commissioning standards—from load analysis to advanced testing—to ensure each installation performs exactly as designed.

Project Overview: Right-Sizing for Comfort and Efficiency

Many comfort complaints in Texas homes trace back to improper system sizing. Oversized equipment short-cycles and struggles with humidity; undersized systems run continuously without meeting demand. For this Southlake residence, Greentech evaluated the home’s cooling and heating requirements and recommended a 3-ton heat pump to better match the load profile.

The result is a balanced system that delivers:

• More consistent temperatures across rooms
• Improved humidity control during hot, humid summers
• Higher efficiency under real-world operating conditions

Frequently Asked Questions (Q&A)

Q1: Is a 15.2 SEER2 heat pump efficient enough for Texas?

Yes. A 15.2 SEER2 heat pump meets current DOE standards and provides an excellent balance of efficiency, upfront cost, and reliability for North Texas climates—especially when properly sized and installed.

Q2: Why was the system upgraded from 2 tons to 3 tons?

After evaluating the home’s cooling and heating load, a 3-ton system was determined to be the correct capacity. Proper sizing improves comfort, reduces run-time stress, and enhances humidity control.

Q3: What does a 500-micron vacuum mean?

Evacuating the system to 500 microns confirms that moisture and contaminants have been removed from the refrigerant lines. This step is critical for compressor longevity and system efficiency.

Q4: How long does a Daikin heat pump typically last?

With professional installation and regular maintenance, a Daikin heat pump can deliver 15–20 years of reliable service.

Q5: Does this system qualify for rebates or tax credits?

Eligibility depends on federal, state, and utility programs available at the time of installation. Our team reviews current incentives during the consultation process.
