Package Unit Repair & Replacement in Walnut
When a package unit breaks down at your Walnut home or business, you need a contractor who will give you a straight answer and a clear price before any work begins. That is exactly how Season Control HVAC handles every package unit repair and replacement call in Walnut and the surrounding San Gabriel Valley. We show up, diagnose the problem, and walk you through your options with upfront pricing and no surprise charges.
Our California contractor license is #795799, and we have been in business since 2001, delivering over 25 years of HVAC service across Greater Los Angeles. Whether your rooftop unit needs a compressor swap, a control board replacement, or a full equipment upgrade, Walnut residents and local businesses can count on clear credentials and a long track record backing every job we perform.
Package unit repair and replacement demand in Walnut and nearby San Gabriel Valley communities stays consistent year-round because these self-contained systems handle both heating and cooling from a single cabinet, typically mounted on a rooftop or concrete pad. Walnut residents and local businesses rely on package units in a range of building types, from single-story commercial spaces to residences where indoor mechanical room space is limited. Hot summers in the San Gabriel Valley push these units hard, and aging equipment can develop refrigerant leaks, failing blower motors, or corroded heat exchangers that demand prompt diagnosis. Rooftop access planning matters here because safe equipment removal and crane coordination vary from building to building. Season Control HVAC evaluates each site individually so the scope and cost are transparent before we begin. Nearby communities in Alhambra, Arcadia, and Azusa face similar conditions, and our service area spans 143 cities across Greater Los Angeles.

Package Unit Repair & Replacement in Walnut - FAQ
How much does package unit replacement typically cost, and what affects the price?
The total cost depends on the unit size, efficiency rating, mounting location, and whether ductwork modifications are needed. We provide a written estimate after an on-site evaluation so you see the full price before any work starts. No surprise charges.
How long does a package unit replacement take from start to finish?
Most residential replacements are completed in one day once equipment is on hand. Commercial rooftop installations may take longer depending on crane scheduling and building access. We outline the timeline during your estimate appointment.
Can you repair my existing package unit, or does it need to be replaced?
We always diagnose first. If the repair cost is reasonable relative to the age and condition of the unit, we recommend repairing it. When repair expenses approach the value of a new system, we present replacement options with clear cost comparisons so you can make an informed decision.

“I cannot speak highly enough about my experience with Seasons Control. From the initial consultation to the final installation, the entire process was seamless and exceeded expectations. Tomar was truly exceptional. He took the time to carefully listen to all of my concerns and specific needs for both my daughter and me. His attention to detail, professionalism, and genuine care made all the difference. The installation crew, led by Pablo, delivered outstanding workmanship. Their communication was clear and timely throughout the entire project. I appreciated their integrity and commitment to doing the job right. They treated our home with care and respect, and the end result was high-quality work that we can trust. I highly recommend Seasons Control to anyone looking for a company that combines technical expertise with excellent customer service. Thank you, Tomar and Pablo, for making this such a positive and stress-free experience. Thank You!”
“Tomer was on time, and very quickly diagnosed our problem. We have an air conditioner that seemed to have a leak and he gave us all scenarios, and explained everything until we understood how it worked and what we could do in the event of anything else happening to it. I believe he saved us money thanks to his great communication. Now, we understand the unit that we currently have, and what all our options are. Tomer gave us a feeling of relief, because he's definetinely a pro at this. We will be using this company again after our experience with Season Control Hesting & Air Conditioner. Like Tomer said "Now YOU control the air, not the AIR controlling you!" Lol!! Thanks again Tomer!”
“I have recently replaced an almost 30-year-old HVAC with this servicer through multiple quotations. I am so glad to make the right call. Its quotation is very competitive and the technician(Eric) is well-experienced and knowledgeable in walking me through the whole process in detail. Upon installation is complete, they did thorough testing to check if everything went well; and called me a few days later to follow up with the performance of the unit. I could not be happier with this smooth transaction.”
