Roznovak'S Services,Inc

Roznovak's Services, Inc works out of Round Rock, TX as HVAC contractors who cover air conditioning and heating jobs for homes and businesses throughout the Austin area. The company has handled this type of work since 1979 and keeps a radiator shop on the side for rebuilds, repairs, and cleaning on trucks and industrial units. Round Rock summers hit hard with long stretches of triple-digit heat, so the crew stays ready for everything from quick fixes on failing units to complete system swaps and duct sealing. They also take on commercial work like walk-in coolers, freezers, and large dehumidifiers when those systems break down in local shops and warehouses.

Their day-to-day covers air conditioning installation and repair, heat pump service, furnace work, thermostat replacements, zone controls, and indoor air quality upgrades such as filtration and UV purifiers. One family watched the crew keep an old furnace running through another winter until a new unit could go in, and that temporary fix held solid for four years afterward at a price that stayed reasonable. Tech Michael arrived for a diagnostic call, walked through every step without rushing, stayed polite while a two-year-old napped nearby, and gave honest answers instead of upselling. Other calls involved straightforward furnace repairs and full replacements where the crew answered the phone fast and laid out the plan before starting.

Homeowners keep coming back because the techs show up on time, explain the problem in plain terms, and quote prices that hold without surprise add-ons. Reviews point to consistent quality on both small repairs and bigger installs, solid communication from the first call through the final walkthrough, and work that lasts without callbacks. The crew earns steady marks for moving fast when the heat or cold hits and for treating every house like regular work instead of a sales pitch. DIRT Score 4.48 from 52 reviews on Finds.

“If I could give this company 10 stars I would! Michael was the tech that came out to look at our issue and he was absolutely amazing. He was super polite, knowledgeable and completely honest about every step of the process. We also had our 2 year old laying down for a nap and he was so accommodating to that as well being as quiet as he could and he did not wake her up. He also took extra time to write everything down step by step as to how to maintain what we needed to do to keep our air conditioner on the settings to fix our issue. Also customer service when I called to rave about it was out of this world!”
