HVAC Repair in Pasadena

Cold Cloud repairs AC units, furnaces, heat pumps, thermostats, and airflow problems for homes and light commercial spaces throughout Pasadena. Our licensed technicians inspect the full system before recommending any fix, so you know exactly what’s wrong and what it will cost before we start.

Common signs it’s time to call us:

  • Hot or cold spots that won’t go away
  • Rising energy bills with no clear cause
  • A system that short-cycles, won’t turn on, or makes odd noises

Pasadena homeowners call Cold Cloud for HVAC repair because we diagnose first and recommend second. Our CSLB C-20 licensed, EPA 608-certified technicians look past the obvious symptom to find the real cause, whether it’s electrical, mechanical, or refrigerant-related. You get a clear, upfront price before any work begins, and a repair backed by a written warranty, not a guess dressed up as a fix.

AC Repair
Warm air, weak airflow, or a unit that won’t turn on. We pinpoint the cause and restore cooling to your Pasadena home, often in a single visit.

Furnace Repair
A furnace that cycles on and off or won’t heat properly needs more than a guess. We inspect every component and repair it safely.

Mini Split Repair
Ductless systems need specialized know-how. Our technicians diagnose and repair mini splits without guesswork or unnecessary part swaps.

Thermostat & Airflow Repair
Hot spots or a thermostat that won’t communicate with your system? We calibrate controls and correct airflow issues at the source.

If your system is over 10 years old, breaks down repeatedly, or repair costs are creeping close to the price of a new unit, replacement often makes more financial sense. We’ll give you an honest read on which option fits your system and your budget, no pressure either way.

    what we provide

    Energy Efficiency Improvements & Available Rebates

    A repair estimate shouldn’t come with hidden fees. Cold Cloud provides upfront pricing before any work begins, so you know the full cost up front, not after the job is done. Every repair is backed by a written warranty, giving you confidence that the fix will hold. If a part fails within the warranty period, we make it right at no extra charge.

    Guesswork leads to repeat repairs. Before recommending a fix, Cold Cloud technicians run a full diagnostic on your system, checking electrical connections, refrigerant levels, airflow, and mechanical components. This comprehensive approach means we catch the actual cause of the problem instead of patching a symptom that returns a few months later.

    Google review★★★★★
    I just had a new mini-split system installed by Cold Cloud Mechanical. I couldn’t be happier. I met with 6 companies for this project and each one had a different idea for the plan. Alex’s plan was clearly the best and smartest. It was also the most complicated! I'm very impressed with the installation. Suren and Sebastian were fantastic. They executed the complicated plan brilliantly. One can hardly notice the pipes as they are all buried within walls and in closets. The condenser was placed in a place where it is hardly noticed. I highly recommend Cold Cloud for any HVAC needs. I will definitely be switching to Cold Cloud for maintenance and repair of the other systems in my house. They clearly know what they are doing.

    My AC unit wasn’t working properly, and other technicians told me everything was fine. Nick from Cold Cloud Mechanical was able to identify and fix the issue. He was professional, patient, and took the time to clearly explain all my options. Great expert and a great guy. I highly recommend him!

    My mini split stopped blowing cold air so I put in a request for quote on Yelp, got about five replies. Four of them sounded shady as hell, some of them not responding to my questions, not wanting to repair my system because profit margins were too low, or requesting absurd amounts of money upfront, but Cold Cloud Mechanical was super responsive and able to send someone out at no cost the day of. The technician, Alex, was super knowledgeable, noticing issues with my system and explained what fix he recommended, all that for free, meaning I could have taken the info and looked for someone else to do the repair. But the quoted price was super fair so I went with it and the repair was done by the next morning while I was at work. I'm really happy I decided to work with them, the craftsmanship was great and I'm pretty sure other companies would have charged me much more for less.

    Our upstairs level gets very hot during the summer, especially in our kids' room, and so we were investigating installing a mini-split in that room. We got a number of quotes, but Alex was the only one who thoroughly measured room dimensions, air flow from each vent, etc. I was extremely impressed with his thoroughness and the amount of thought that went into his recommendations. We hired Cold Cloud, and they re-did the ductwork, installed dampers, set up a 3-zone system, and installed an air cleaner. We did not go forward with the mini-split option, and the cost for revamping the whole system was comparable to the mini-split quotes I was getting from other providers. Our house is much more comfortable, and it looks like our electricity bill is going to go down significantly as a result. Overall, I am extremely happy with the outcome. The only negative experience I had was communication with the front office - the team was hours late on the first day and the front office kept telling me that they are "really close" or "30 minutes away" multiple times. When they arrived, it turned out that a part was needed from Long Beach and they had to go get it - if the office had simply communicated that to me I would have been much more understanding of the delay. However, the team arrived on time for each subsequent day. They were very flexible with scheduling, cleaned up well after themselves, and we had minimal disruption while they worked. I especially want to highlight how amazing Alex was - if I ever need further work on my HVAC system I will definitely be reaching out to him first.

    We had an excellent experience with Cold Cloud Mechanical to repair our AC unit. They responded quickly to our request, sent their Service Technician the next day who did a thorough check on what went wrong with the unit. He explained everything to us and gave us a fair estimate. We went ahead with the repair and everything is working perfectly now. I would highly recommend Cold Cloud Mechanical for any AC unit repairs.

    Alex did analysis starting from the blower to the conductor. In the beginning he suspect it was the issue with signal wire, but then later he thought about it's probably with the conductor. After replacing the conductor, the compressor returned to work. In contrast to the repairman visited 1 day before, the last person couldn't fix the problem, but still charge me $165, and tried to convince me install a new system. Alex's service is professional. He fix the problem.

    Questions Worth Asking Before You Approve a Repair

    Service DetailWhy It Matters
    Is the system on R-22 refrigerant?R-22 is phased out — a recharge runs expensive and argues for replacement over a refill
    Is the failed part under the manufacturer's parts warranty?A compressor or coil can be factory-covered for 10 years even when the labor isn't
    The $5,000 ruleMultiply the unit's age by the repair quote; past ~$5,000 replacement usually wins
    Get the failed reading documented, not just the part nameA logged measurement (microfarads, amps, subcool) protects you from paying twice
    Is the diagnostic fee credited toward the repair?Ask up front — many shops waive it once you approve the work
