Cooling for Dallas summers and winter freezes.

Dallas summers bring 20 to 40 or more days of triple-digit heat, and winters bring regular freezes. Many homes have horizontal equipment in high-pitched attics.

## Climate

Dallas sits in IECC Climate Zone 3A (with Tarrant County and southern metro pockets bordering 2A). Summers bring 20 to 40+ days of triple-digit heat that push attic temperatures past 145°F, demanding condensers that won't trip on high head pressure. Winters are brisker than in South Texas, with regular freezes that require dependable gas furnaces or cold-weather heat pumps.

## Local homes

Older Dallas neighborhoods like Lakewood, M Streets, Oak Cliff, and Bluffview feature 1920s–1950s pier-and-beam cottages where crawlspace ductwork is tight. Post-1960s neighborhoods across Lake Highlands, Richardson, Plano, Frisco, McKinney, and Irving are built on expansive blackland clay slabs with horizontal HVAC equipment tucked into high-pitched attics.

## Utilities

Oncor Electric Delivery provides electric grid delivery (paired with your chosen retail electricity provider), and Atmos Energy supplies natural gas across Dallas–Fort Worth. Oncor sponsors residential energy-efficiency incentives for qualifying heat pump and AC replacements.

## Recommended systems

- [AC replacement](https://ethohome.com/services/ac-replacement/): Paired with a gas furnace, a two-stage or variable-speed central AC keeps Dallas-area slab homes cool even when afternoon highs top 102°F.
- [Heat pumps](https://ethohome.com/services/heat-pumps/): Dual-fuel and inverter heat pumps can lower electricity use during North Texas's long spring and fall seasons and qualify for Oncor efficiency incentives.
- [Furnace replacement](https://ethohome.com/services/furnace-replacement/): Replacing an attic gas furnace alongside your AC gives you a variable-speed ECM blower for summer cooling and reliable warmth during North Texas ice storms.

## Questions

### My Dallas-area home has two HVAC systems in the attic—do I have to replace both at once?

No. Many two-story homes in Plano, Frisco, and North Dallas split upstairs and downstairs into two independent attic systems. You can replace the failing unit (most often the harder-working upstairs system) first, or replace both together for bundled savings.

### How do Oncor HVAC incentives work in the Dallas area?

Oncor offers residential incentives through participating contractors for upgrading to qualifying heat pumps and air conditioners. We design matched AHRI-rated systems that align with North Texas efficiency standards.

### Can shifting North Texas clay soil affect my outdoor AC unit?

Yes. Blackland prairie clay expands when wet and shrinks during summer droughts, tilting old concrete condenser pads. During replacement, our crews level and set a stable composite pad and verify refrigerant line flexibility so soil movement doesn't stress copper joints.
