HUS vs Southwest Heating & Air, line by line.
The HUS difference, in four points.
Every upgrade, one contractor
HVAC + solar + battery + roofing + EV under one contract. A heating-and-air shop can't bundle.
Heat pump + solar, designed together
We engineer your heat pump and solar as one system so cooling runs on power you generate.
Powerwall sized to run your AC
We size your Tesla Powerwall to keep essentials — including AC — running through outages.
Same HVAC quality, rebates handled
In-house technicians, Manual J load calcs, premium equipment — plus we review incentive documents. C-20 licensed since 2017.
Which one is right for your home?
When Southwest H&A is the right choice
Southwest Heating & Air is a longtime San Fernando Valley HVAC specialist with strong residential and commercial HVAC experience. For pure heating and air work in the Valley, they're a solid choice.
When Home Upgrade Specialist is the right choice
If your project goes beyond HVAC — adding solar, battery, roof, or EV — HUS does it all under one contract. We design heat pump + solar together so your cooling runs on power you generate.
The honest verdict
Both install excellent HVAC. Southwest brings 30 years of pure HVAC focus; HUS brings the same install quality plus solar, battery, roofing, and EV in one coordinated project.
Everything under one roof.
Questions to ask before choosing either company.
- ✓System sizing: ask whether the estimate includes Manual J or load-size review, not only old equipment size.
- ✓Ductwork: confirm whether airflow, return sizing, duct leakage and attic access were reviewed.
- ✓Electrical scope: ask whether a heat pump, EV charger, solar system or Powerwall changes panel requirements.
- ✓Permits and testing: confirm permit responsibility, HERS testing, inspection steps and warranty documentation.
- ✓Future upgrades: if solar, roofing or battery backup may happen later, ask whether the HVAC design is ready for that plan.
