Oscar's Cooling and Heating LLC

Oscar's Cooling and Heating LLC runs its HVAC operations from Green Valley and serves the surrounding spots including Sahuarita and the greater Tucson area. The outfit handles air conditioning and heating work for homes in this region where the weather stays hot for months on end. Their focus stays on repair jobs, new system installs, and regular maintenance to keep units operating through the long summers. Homeowners here often face units that quit during peak heat or older systems that need updates to handle the load without constant breakdowns. The crew shows up ready to diagnose issues on site and get things sorted without dragging out the process.

They perform air conditioning repairs on units that stop cooling properly along with full installations when a system reaches the end of its life. Maintenance visits cover cleaning coils, checking refrigerant levels, and testing heating components before winter hits so nothing fails unexpectedly. In this climate common problems include compressors working overtime or filters clogging fast from dust, and the team addresses those directly with the parts and tools needed on the truck. Calls come in for everything from emergency fixes on hot days to scheduled tune ups that prevent bigger failures down the line. Work stays practical with clear explanations on what needs doing and how long it will take.

Customers keep coming back because the service runs quick and the fixes hold up without repeated visits. The high marks come from solid quality on the actual repairs and installs plus fair pricing that matches the work done. Communication stays direct so homeowners know the status at each step and feel the price reflects real value. Speed matters when the temperature climbs and this crew delivers on that front consistently across many jobs. DIRT Score 4.99 from 1596 reviews on Finds.

“We recently had a new AC system installed by Oscar's Cooling and Heating, and we couldn't be happier with the experience. They installed an affordable, top-quality Trane unit, which is already running incredibly smoothly and cooling the house perfectly. The team was outstanding. Well mannered, respectful of our property, and hard working from start to finish. One of them also took the time to show me how to work the new thermostat and even scheduled a post-install appointment to make sure everything is humming along perfectly. It's rare to find a team that shows this level of professionalism while ensuring everything is installed flawlessly. Trust me, you'll be very happy with your new AC from these guys. Highly recommended!”

“I recently hired Oscar’s to do a completely new AC install. Their communication was flawless and their pricing was by far the best compared to 3 other quotes. Edgar and Mike made the whole process a breeze. Overall I am very satisfied with their work product and their professionalism. I will be using them for my future HVAC needs.”

“I had an excellent experience with this company. My AC stopped working yesterday afternoon, so I called earlier today, and Oscar was incredibly kind, understanding, and professional from the start. He arrived at my home in less than two hours, which I truly appreciated, especially in this Arizona heat. Oscar quickly diagnosed the issue and had my AC running again in less than five minutes. He was knowledgeable, efficient, honest, and respectful throughout the entire visit. It’s not often you find someone who is this reliable and trustworthy. I highly recommend Oscar and this company to anyone needing AC service. Thank you for the outstanding customer service and for getting my home cool again so quickly. Five stars all the way!”

“Today was my first experience with Oscar’s Heating & Cooling, and it was a great one. I signed up for their A/C system maintenance plan. They provided me a 3 hour window on their possible arrival to my home. I got a text and a call from the technician letting me know he was arriving soon. Junior, the technician, was very polite and professional. He communicated to me all the details of my current unit and gave me recommendations of what could be done in the future. Thank you Junior & Oscar’s for all your help!”

“Honestly I can’t say enough good things about this company! Two years ago my AC went out in the middle of the summer with 3 kids my house was heating up fast. I had just gotten a tune up by Alaskian AC company and they mentioned it would be running good for the summer, well it went out so they were my first call. I mentioned the tune up and the guarantee and they came out and said the part that broke wasn’t under there guarantee and wanted to charge me $400 to fix it. I refused and was super upset. After reaching out on the Rancho page I got connected with Oscars AC, Oscar came out himself the same day fixed the AC for around $140, two years later I decided Oscar’s would be the first place I would call for a new AC. The had the lowest price, they were friendly, they were great with my kid”

“Oscar's Cooling and Heating provided excellent CUSTOMER service! The individual who answered the phone was very professional. The field technician was very timely and equally professional and most knowledgeable. Oscar's was able to squeeze me in during a hot, summer day in Tucson! And at a fair price! Family owned and operated companies still do provide customer service, something very rare in today's business climate! I encourage you to try Oscar's Cooling and Heating!”

“Oscar's Cooling and Heating is the place to go for great service! I called and they were at my house so fast. Ruben and Jose were the techs and they were amazing. So personable and friendly. Unfortunately my system was too far gone so a few days later they installed a new system! Oscar and Trini are amazing, and really care about the community. Diane was a pleasure to work with over the phone. So help your local business for you heating and cooling needs..... Oscar's Cooling and Heating!!”

“I can't say enough great things about Oscar's Cooling & Heating! Our AC started leaking through the ceiling last night, leaving us without air conditioning overnight in the Arizona heat. I called Oscar's at 7:30 a.m. and was greeted by Diana, who was an absolute delight. It's so refreshing to receive such friendly, caring customer service first thing in the morning. To my surprise, they had a technician at our house by 8:30 a.m.! Mike was professional, polite, and extremely knowledgeable. He quickly diagnosed the problem, explained everything clearly, and had our AC repaired in no time. I was honestly worried the repair was going to cost a fortune after seeing water coming through the ceiling, but the price was very fair and didn't break the bank at all. From Diana's outstanding customer s”

“If you read past reviews, you will see this is not just my opinion but many others have had the same experience as I did. From the sales process through the installation this was the most professional interaction with a organization that I have ever had. The installation was professionally designed and accomplished by a very professional team that exceeded my expectations at every step, I could go on forever, but if you are in need of a new system, I highly recommend Oscar's!”

“Oscar’s Cooling and Heating exceeded my expectations from start to finish. They were quick to come out and provide a bid, and unlike other contractors, they asked detailed questions that others never thought to ask. They took the time to explain my options, provide recommendations, and make sure I understood the benefits of the different systems. Not only did they offer me a better price, but they also provided a higher-quality system with more features and perks than the other A/C companies I contacted. Their communication throughout the process was excellent, and they were efficient every step of the way. What stood out most was that they genuinely seem to care about their customers. It doesn’t feel like just a job to them—they take pride in their work and want to make sure you get the b”
