Professional Mueller Industries Service in Pasadena
Keep your Pasadena business running smoothly with our expert Mueller Industries rooftop package unit repair & installation in los angeles services. We specialize in minimizing downtime and maximizing efficiency. Rooftop package units (RTUs) are the most common commercial HVAC solution, providing all heating and cooling components in a single outdoor unit. Our rooftop unit services keep commercial buildings comfortable and energy-efficient. We service all major rooftop unit brands including Johnson Controls, American Standard, ICP, Goodman, and Daikin. Our technicians have extensive experience with package units ranging from 3 to 50+ tons capacity. Rooftop units contain the compressor, condenser, evaporator, and air handler in one cabinet mounted on the building roof. This design saves indoor space and simplifies maintenance access. However, rooftop location exposes equipment to weather and requires specialized service expertise. Common rooftop unit problems include refrigerant leaks, compressor failures, blower motor issues, control board problems, economizer malfunctions, and heating element failures. Our technicians are equipped to handle all repairs safely on rooftops. Our rooftop unit installation service includes crane or rigging services for unit placement, curb adapter installation, ductwork connections, electrical hookup, refrigerant lines (if applicable), condensate drainage, and complete system startup and testing. Preventive maintenance for rooftop units is especially important due to weather exposure. Our service includes filter replacement, coil cleaning, belt inspection and adjustment, motor lubrication, electrical connection tightening, refrigerant level check, economizer operation testing, and control calibration. Regular maintenance prevents premature failures, reduces energy consumption, ensures consistent comfort, and can extend rooftop unit lifespan to 15-20 years. We offer customized maintenance contracts for single units or multiple buildings. ### Serving Pasadena and Surrounding Areas Our technicians are frequently in Old Pasadena, Playhouse Village, South Lake and throughout Pasadena.

I highly recommend this AC repair company! They did an excellent job fixing my air conditioner — fast, professional, and very reliable. I also had my commercial freezer repaired by them, and just like before, the service was top-notch. Their team really knows what they're doing, and they always make sure everything is working perfectly before they leave. Definitely the best repair service I've worked with!

We had an issue with our walk-in freezer and these guys were amazing. They showed up quickly, diagnosed the problem right away, and had everything up and running in no time. Professional, knowledgeable, and very easy to work with. Highly recommended for any commercial refrigeration needs!

Called them to service a commercial ice machine. They were able to send out a technician the next day. He was able to diagnose the issue and fixed the machine. He also stayed for a few cycles, to make sure the issue was resolved.

We found this company on Google. Iriana is excellent customer service. Alex is genius. He repaired 2 of our refrigerators that had major issues. He found the issue and he fixed it immediately. Request for Alex for sure.

Have a small commercial fridge that was running constantly so needed a check up. seemed the thermostat was broken. got a new one as well as a cleaning of the condensor. working well now hope the electric bill will go down. After a few months I noticed the fixed fridge didn't seem to be working optimally still and had them send a tech out to check. turns out it's a 13 y o fridge with all original parts. a good sign but also a sign that on the original inspection that tech probably should have checked the coolant levels. long story short, turns out after checking the levels were low and more was added. it now is really working as it should. The best part of this review is that after paying, I thought about it more and called them asking for some sort of reduction on the bill as it all could have been addressed in the first visit. I thought only paying for 1/2 of the service fee visit (not the coolant of course) would be a fair compromise. after thinking it over on their end they actually reimbursed me for the entire service fee. I am impressed at their level of service, customer service and business sense.
