What recent reviews say

Gabriel's diagnosis of a shorted compressor wire saved one homeowner thousands of dollars; Brian and Jeff handled emergency calls with speed and professionalism. Technicians explain work clearly and keep homes cool fast, but non-members face week-long waits during peak heat. Those who pay for their annual maintenance plan ($660/year) unlock priority scheduling and lower repair rates.

All Out Cooling & Heating

5.0(581)✓ Google-verified

All Out's technicians earn consistent praise for speed, honesty, and clear communication, with Cameron Brown and Tre singled out repeatedly for professionalism and willingness to explain systems without hard selling. One long-standing customer found repeated scheduling failures and a pushy $2000 upsell on a warranty-covered part, followed by ignored cancellation requests and persistent text solicitations despite complaints. Most reviewers report same-day or next-day visits, fair pricing, and genuine effort to educate rather than sell. Weekend emergency service and thorough documentation (photos for insurance) also stand out. The annual maintenance plan is praised as value-for-money, though the one detractor's experience suggests execution gaps and aggressive sales follow-ups that undercut the stated culture of customer care.

Viking Heating and Air Conditioning

4.9(439)✓ Google-verified

Scott and the Viking crew show up on time during Phoenix heat waves, diagnose AC problems fast, and explain what they're fixing so you understand it. They handle emergency calls the same day, remember to bring a smile, and stick around until the system runs cold again. Reviewers consistently name specific technicians (Scott, Pat, Owen, Austin) and praise their mix of skill and patience, especially when handling salon and home AC during summer peaks. Maintenance tune-ups get the same care as emergency repairs. The business pulls records across multiple units per property and hands customers a checklist for upkeep between visits. One reviewer noted the company even helped keep a dog calm during the call. Their website states they've operated since 2016 and cover Chandler, Gilbert, Mesa, Phoenix, Scottsdale, Tempe, and Maricopa and Pinal counties.
