HVAC in Round Rock
Round Rock is one of the largest suburbs north of Austin, with neighborhoods built over several decades, from established 1970s and 1980s subdivisions to new master-planned communities. Systems of very different ages and refrigerant types exist side by side here.
Electric utility and rebates
The City of Round Rock's new-resident information says Oncor delivers electricity and residents choose a retail electric provider through Power to Choose. Gas service is from Atmos Energy. PEC also lists Round Rock as a franchise city, so some addresses may be PEC members. Oncor's Take A Load Off Texas page said 2026 residential incentive funding was fully committed, so check again for the next program year.
Things worth knowing in Round Rock
- Older Round Rock homes may still have R-22 systems. Repairs involving refrigerant on those are expensive, which is often the point where replacement makes sense.
- In a deregulated area, your retail provider's rate plan affects how quickly efficiency upgrades pay back.
Climate
Round Rock doesn't publish its own climate normals that we could find. As a regional reference, the National Weather Service's 1991–2020 normals for Austin's Camp Mabry station show a normal August high of 97.8°F, with almost every August day reaching 90°F or more. Conditions in Round Rock can differ somewhat, but the long cooling season is the same, which is why spring tune-ups and prompt AC repair matter here.
Permits
The City of Round Rock issues building and mechanical permits inside city limits. Your contractor should pull the permit and schedule any inspection.
Round Rock HVAC FAQs
Can I get an Oncor rebate?
Oncor's incentives are paid through participating service providers and depend on yearly funding. The 2026 funds were listed as exhausted.
Who supplies gas in Round Rock?
The city lists Atmos Energy.
Do you do the HVAC work yourselves?
No. We're a referral service. Your request goes to an independent HVAC contractor licensed by the Texas Department of Licensing and Regulation (TDLR), who contracts with you directly.
Does it cost anything to submit a request?
No. It's free for homeowners, and there's no obligation. We may be compensated by the contractor for the referral.
How do I check a contractor's license?
Search the company or license number at tdlr.texas.gov/LicenseSearch. Texas law requires air conditioning contractors to show their license number on advertising and quotes.
Should I get more than one quote?
For big jobs like a replacement, many homeowners get two or three itemized quotes and compare equipment, scope and warranty. For major repairs, a second opinion is reasonable.
Should I repair or replace an older system?
Age, the size of the repair, refrigerant type and repair history all matter. A newer system with a single failure is usually worth fixing. Older systems facing a compressor or coil repair are often compared with replacement.
Is R-410A being banned?
No. New R-410A equipment is no longer made, but existing systems can still be legally serviced and repaired. Be cautious of anyone using a 'ban' to push a replacement.
How often should I change my air filter?
Commonly every one to three months for 1-inch filters, and more often in summer, with pets, or during cedar season.
How fast can someone come out?
Many contractors offer same-day or next-day service, but it depends on demand. We can't promise arrival times.
