What Your Neighbors Are Saying About Us

Nate with the rest of the team Jason, Keith and Julio who were all very helpful, professional and hardworking. I can’t say enough about their service and dedication to their job to provide a quality product , which was evident. I highly recommend the Rescue Air one for all your air conditioning needs. Great job team and thank you for all your hard work.

Wayne was such a down to earth young man. He was very helpful and even moved my granddaughter's swing set because the bad storm tore thru my back yard. I appreciate the hard work and kindness from Wayne. Last week the other young man also worked the inside terminal only because of the storm but he was great as well. Thank you Rescue Air One for your maintenance guys. They are such a blessing.

Mathew was so great! He was very thorough and so completely friendly and best customer service! I owned a restaurant for 10+ years so I know great customer service when I see it!!! I will ask for him for all our HVAC services! We have the every 6 month maintenance for 5 years and it’s worth it by far, and now that Mathew is with them, major bonus!

These guys are amazing. They were very professional polite and did a wonderful job. I was amazed at how friendly All of them were. I would recommend these guys to everyone and their prices are very affordable, especially if you sign up for the five year program. You will save so much money with this company. I recommend them highly.

Rescue One is all over it. This is my second time calling them for a new unit (Variable Speed Carrier Infinity). Both times I called, they had a Rep onsite the next day. Agreed to the terms and which Unit I wanted. Then the next day they were installed. Quick, timely, and no wasted time. Can't recommend enough. Plus their partnership with Wells Fargo allowed for Zero percent financing. Can't be beat.

How to Know When It's Time for a New AC

Sometimes a repair isn’t enough, and continuing to patch an old system can cost more than replacing it. Here are some signs it may be time for a new AC:

The system is 10 to 15 years old
Frequent or costly repairs
Rising energy bills without explanation
Inconsistent cooling throughout the home
Refrigerant type no longer available
The system runs constantly but struggles to cool
Excessive noise or persistent odors

If your system shows more than one of these signs at the same time, replacement is likely the more practical and cost-effective option. Our technicians can walk you through an honest comparison of repair versus replacement so you can make the right call for your home and budget.

What Causes AC Systems to Fail Prematurely

In Tempe, air conditioners work harder and longer than in most other climates. Systems that run year-round are subject to wear that shortens their lifespan if they aren’t properly maintained.

Skipping annual maintenance is one of the biggest contributors to early failure. Without regular cleaning and tune-ups, components like the compressor and condenser coil degrade faster under the relentless heat. Oversized or undersized equipment is another common issue. When a system isn’t matched to the home’s size and layout, it cycles inefficiently and wears out sooner.

Poor installation also plays a significant role. A system that wasn’t set up correctly from the start may never operate at full efficiency, leading to premature breakdowns regardless of how well it’s maintained afterward. Choosing the right installer matters just as much as choosing the right equipment.

Our AC Installation & Replacement Services

Rescue One Air Cooling, Heating & Plumbing handles every aspect of AC installation and replacement from start to finish. We work with all major brands and install central air conditioning systems, ductless mini-splits, and heat pumps.

Our process begins with a home comfort assessment to determine the right system size and type for your space. Proper sizing is critical in Tempe’s climate, where an undersized unit will struggle on the hottest days, and an oversized one will cycle on and off without properly controlling humidity. Once we’ve identified the best fit, we handle the full installation,n including removal and disposal of your old equipment, system setup, and a complete test run to confirm everything is working as it should. We also walk you through your new system so you know how to get the most out of it from day one.

Emergency AC Replacement Services

When an AC system fails during a Tempe summer, waiting days for a replacement isn’t an option. Our team offers extended service hours from 7 a.m. to 8 p.m., seven days a week, to respond to urgent replacement needs as quickly as possible.

If your system is beyond repair, we can assess your options and proceed with a replacement without unnecessary delays. We keep a strong inventory of equipment on hand so we can get your home cooling again as fast as possible. When temperatures outside are extreme, we treat every installation with the urgency it deserves.

FAQs

How long does an AC installation take?

Most installations are completed in a single day. The timeline can vary depending on the system type and any modifications needed in your home.

How do I know what size AC I need?

Sizing depends on your home’s square footage, layout, insulation, and other factors. Our technicians perform a full assessment before recommending a system.

Will a new AC lower my energy bills?

In most cases, yes. Modern systems are significantly more efficient than older models, and proper sizing helps ensure they run optimally.

How long should a new AC system last in Tempe?

With proper maintenance, most systems last 12 to 15 years. Tempe’s heat can shorten that window without regular tune-ups.

Do you remove and dispose of the old system?

Yes, we handle full removal and disposal of your existing equipment as part of the installation process.
