About Shamrock Heating & Cooling

Since 1996, Shamrock Heating & Cooling has provided expert HVAC services to homeowners across the Phoenix metro area, including Tempe, Ahwatukee, Phoenix, Glendale, Scottsdale, Mesa, and Chandler. As a family-owned and operated company based in Tempe, Shamrock focuses on honest recommendations, reliable workmanship, and long-term comfort for every home it serves.

Founded by Sean in 1996, the company has built its reputation on friendly service, technical expertise, and a “customers first” mindset. Whether you need fast repairs, a full system replacement, or seasonal maintenance, Shamrock offers options—not ultimatums—so you can choose the solution that fits your home and budget. To make comfort more affordable, the team provides flexible financing, Energy Saver Plans, and access to available tax credits and rebates where applicable.

Shamrock stands behind its work with strong warranties, including “can’t write a check” protection on many repair solutions and new system installations. Many repairs include up to five years of parts and labor coverage, with extended protections and transferable warranties on qualifying systems. Customers can also enroll in our Comfort Club Membership that include professional cleanings, seasonal tune-ups, extended warranties, and discounts on repairs to help systems run efficiently year-round.

Because customer service is the company’s number one priority, Shamrock offers fast, same-day service for emergencies and works hard to respond quickly during extreme Arizona temperatures. The company maintains strong ratings with trusted organizations and focuses on doing the job right the first time, following all applicable codes and standards while staying on time and on budget. This commitment to quality, reliability, and integrity is why so many Phoenix-area homeowners continue to trust Shamrock Heating & Cooling in Tempe, AZ with their home comfort needs.

Shamrock Heating & Cooling's Team

Shamrock Heating & Cooling’s team is made up of highly skilled, licensed, and insured HVAC professionals who are carefully selected for both their technical expertise and their character. The company only hires reliable air conditioning and heating technicians who meet rigorous standards for training, certification, and ongoing education, so every visit is handled by someone who truly knows how to diagnose and solve your comfort problems.

Because the owners know what it feels like to invite strangers into their own home, they follow a simple hiring rule: if they wouldn’t feel comfortable having a technician over for dinner, that person doesn’t work for Shamrock—period. This philosophy ensures that every technician who arrives at your door is not only knowledgeable, but also someone you can trust around your family, your pets, and your belongings.

Customers describe the Shamrock team as helpful, courteous, and honest, with technicians who take time to explain options clearly and never use high-pressure tactics. Each member of the crew is committed to going out of their way to deliver genuinely world-class service—from showing up on time and protecting your home to cleaning up thoroughly after the job is done.

Solving problems the right way the first time and standing behind all work 100 percent is at the core of how the team operates. Whether it is a simple repair, a complex system replacement, or routine maintenance, Shamrock’s technicians focus on quality workmanship, clear communication, and long-term reliability so you can feel confident in your home’s comfort year-round.
