HVAC service truck from Infinity Air Solutions in the Birmingham area

A Family Tradition Built on Trust

Three generations of HVAC experience serving Hoover, Birmingham, and surrounding areas with honesty, craftsmanship, and pride.

Some Things Are Worth Passing Down

Doug Shrewsbury learned this trade the way it should be learned — side by side with his father, starting at age 13. He went on to earn his certifications and licenses, but the most important lessons came long before that: show up on time, be honest, charge a fair price, and take care of people.

In 2009, Doug took everything his father taught him and built Infinity Air Solutions — a company grounded in those same values from day one.

Now his son Nick is coming up through the ranks, and the tradition continues. Nick's skills grow stronger every day, and he's on track to complete the Trane owner course — the industry's mark of a technician and leader ready to carry a business forward.

Three generations of knowledge. One set of values. And a fourth decade of serving the Birmingham area the same way it’s always been done. When you call Infinity Air Solutions, you're not calling a faceless company — you're calling a family that has spent decades earning the trust of neighbors just like you.

HVAC Technician & Owner

Doug Shrewsbury

I’ve spent my life in this trade, and I’ve built my reputation here in the Birmingham area one job at a time. What matters to me is simple — show up when you say you will, be honest about what the customer actually needs, and stand behind the work when the job is done. That’s how I was taught, and it’s how I’ve run this company from day one.

This business carries my name, my family, and my responsibility to the people we serve. When you call Infinity Air Solutions, you’re getting more than a service call — you’re getting someone who takes that seriously every single time.

Nick Shrewsbury

I didn't just grow up around this industry — I grew up in it. Riding along to jobs with my dad, helping on installs, watching how he treated customers. This trade, and this company, have been part of my life for as long as I can remember.

Now at 18, I'm proud to be on the team full-time. I'm still building my skills every day, and I take that seriously — every job is a chance to learn and to get it right. Hoover is my home. These are my neighbors. Treating people with honesty and respect isn't just good business to me, it's personal.

Being part of a family legacy means everything. I'm here to earn your trust and help carry this company forward for years to come.

Keith Lovetto

I've been in this trade since 1997 — and I'm still learning. That's not something I say lightly. Over the decades I've built real hands-on expertise in duct installation, system service, and keeping heating and cooling systems running the way they should. But what I'm most proud of is that I've never stopped showing up to training. Every class available, I take it. This industry evolves, and I think the customers we serve deserve a technician who evolves with it.

What I bring to every job is simple: experience you can count on and work you can trust.
