About Us

An Austin Original Since 1977

McCullough Heating & Air Conditioning

McCullough has operated with exceptional business ethics, quality, and expertise since 1977, earning a spot among both Austin and national leaders in home comfort services and energy conservation.

McCullough is well-respected in the Austin community because of our work with local non-profits, our partnership with the City of Austin, and the thousands of residents we have helped.

We have a reputation for excellence, but don’t be misled – we’re not the most expensive brand on the block. In fact, it’s our depth of understanding in the HVAC business, and our commitment to keeping things honest, that equips us to offer consistently fair prices to our customers.

McCullough Heating & Air Conditioning Is….



If your furnace, heat pump, air conditioner, or ductless system is emitting odors, don’t delay. Our customers report everything from sulfuric or chemical smells,

to hot or burning smells. Many are harmless, and it’s normal to experience certain smells when a system is used for the first time after idling. However, it’s important to troubleshoot your system if it’s emitting odors.

The McCullough Difference

McCullough is a household name in Austin, not because of what we’re capable of, but because of how much we care. Yes, we do what we say we’re going to do. Yes, our technicians are highly skilled, deeply experienced, and well-trained. But, that’s not why we have customers who have been with us for multiple decades. It’s because we treat the entirety of Austin (and our surrounding ‘burbs!) as family.

We don’t compete on price. We don’t compete with tactics or gimmicks. We serve our neighbors with value and care. That’s how it’s always been.
