Rooted in Craftsmanship, Defined by Care: The Day & Night Story

In the heart of the Arizona desert, home comfort isn't just a luxury; it’s a necessity. For over 40 years, Day & Night Air Conditioning, Heating & Plumbing has served as the backbone of reliability for homeowners across Phoenix and the Valley. Founded by Jeff Martin, our company was built on a simple, enduring philosophy: combine old-fashioned craftsmanship with modern innovation to keep your home safe and efficient year-round.

The Difference is Day & Night

What sets us apart? It’s our refusal to cut corners. While the world moves toward faster, cheaper fixes, we remain dedicated to the "old-fashioned way"—listening carefully to your needs, respecting your property as if it were our own, and delivering work that stands the test of time.

Our Guiding Principles:

• True Craftsmanship: We take immense pride in the precision of our work.
• Transparent Honesty: With upfront pricing, you’ll never find a hidden fee or a surprise on your bill.
• Immediate Response: We understand that a broken AC in July is an emergency. That’s why we offer Same Day Service and Next Day Installation.
• A "Home First" Mentality: If we wouldn’t install a specific unit or pipe in our own homes, we won’t recommend it for yours.

A Team of Local Experts

Our strength lies in our people. Led by General Manager Mike Littau and a specialized leadership team across HVAC and Plumbing, we employ NATE-certified technicians who are as passionate about your comfort as you are. From Jeff Lawson and Kevin Osborne in our plumbing division to our dedicated HVAC managers like Justin Lang and Ricky Rodriquez, every member of our team undergoes rigorous training to stay ahead of industry advancements.
