Semper Fi Heating & Cooling has a home base right here in Mesa, with our office located off Clearview Avenue. Our crews serve homeowners throughout the city, including neighborhoods near Downtown Mesa, Falcon Field, Eastmark, Las Sendas, and the communities stretching toward the Superstition Mountains.

Mesa homes put their cooling and plumbing systems through demanding conditions. Long summers keep air conditioners working hard, while the city’s hard water can leave mineral buildup on fixtures and affect plumbing equipment over time. We provide air conditioning, heating, indoor air quality, and plumbing services for Mesa homeowners who need repairs, maintenance, replacements, or help with an urgent problem.

Air Conditioning Services

Air conditioning gets a serious workout in Mesa. Long stretches of extreme heat can expose problems that were easier to ignore during milder weather, including weak airflow, uneven temperatures, short cycling, and systems that struggle to keep the house comfortable. The City of Mesa specifically identifies extreme heat as one of the severe-weather conditions residents should prepare for.

Semper Fi Heating & Cooling handles AC problems as well as planned replacements and routine upkeep.

  • When the house won’t cool properly, AC repair can address the problem before the indoor temperature keeps climbing.
  • Aging equipment or a system that no longer fits the home’s needs may call for air conditioning installation.
  • Regular AC maintenance helps prepare cooling equipment for Mesa’s demanding summer workload.
  • Homeowners looking at their cooling options can start with our main air conditioning services page.
  • For year-round HVAC upkeep, our maintenance plan offers another way to stay ahead of system needs.

Book AC service when your Mesa home starts feeling warmer than it should.

Heating Services

Mesa winters are mild compared with much of the country, but cool desert nights still make dependable heating worthwhile. A furnace or heat pump that has sat mostly idle can reveal ignition, airflow, thermostat, or performance problems once temperatures drop.

We service several types of heating and HVAC equipment found in Valley homes.

  • If the system isn’t producing dependable heat, heating repair can identify what’s keeping it from working properly.
  • Homeowners replacing older equipment can explore heating installation.
  • Seasonal heating maintenance can help uncover developing problems before colder nights arrive.
  • Homes using traditional forced-air equipment can find more information about furnace services.
  • Our main heating services page covers additional options for home heating.

Schedule heating service before a minor problem leaves your Mesa home without dependable heat.

Heat Pumps & Ductless Systems

Heat pumps make sense for many Arizona homeowners because one system can handle both heating and cooling. Ductless equipment can also be useful when a home addition, converted garage, workshop, or individual room needs temperature control without extending existing ductwork.

Home Comfort & Indoor Air Quality

Cooling the house is only part of staying comfortable in Mesa. Dust, duct leakage, insulation, thermostat performance, and indoor air quality can all affect how the home feels and how hard HVAC equipment has to work.

Mesa also has a wide mix of housing ages. The city recognizes multiple historic districts and heritage neighborhoods, including Lehi, Evergreen, Fraser Fields, and West Second Street, alongside much newer development elsewhere in the city. That variety means comfort concerns can differ considerably between properties.

Schedule a home comfort appointment when uneven temperatures or indoor air concerns are affecting your Mesa home.

Plumbing Services

Mesa’s water creates a plumbing concern homeowners can see on faucets and shower doors. According to the City of Mesa, water hardness ranges from 12 to 22 grains per gallon depending on the source serving the property. Calcium and magnesium in the water cause the hardness and familiar chalky mineral deposits.

Semper Fi Heating & Cooling provides plumbing service for everyday repairs as well as larger water, drain, sewer, and gas line concerns.

Schedule plumbing service when leaks, clogs, hot water problems, or mineral buildup start causing trouble.

The office was quick about scheduling an appointment after I had talked to Semper Fi at an event. They were communicative throughout the process too. Jason was the tech that came by for a free HVAC tune up. He was efficient and explained what he found afterwards without being too pushy about getting the work done then. 1 of the jobs I will probably do on my own, and he told me what to make sure I look out for. The other job I will not hesitate to reach out to them to have done.

Mr. McCrae and Pao Pao were very experienced and professional. Both took the time to explain everything and and answer all my questions. Not only were they knowledgeable but they both had a great sense of humor. My belief is they went far beyond to get me the best price for what I can afford and succeeded. I would highly recommend both of these gentlemen.
