We are a family-owned contractor established in 2018, located at 3055 Foothill Blvd in La Crescenta-Montrose, CA.

Our certified HVAC technicians have more than eight years of experience with all makes and models of heating, air conditioning, and air purification systems. We provide AC repair, furnace repair, HVAC installation and replacement, equipment maintenance, and heat pump installation. Rather than recommend repairs without investigation, we examine malfunctioning equipment to determine the source of the issue. We then explain the results, review available solutions, and present a written estimate before beginning the work. Customers receive clear pricing with no hidden charges.
Our services also include emergency HVAC repairs, same-day appointments, thermostat replacement, capacitor replacement, flame sensor replacement, and refrigerant recharges. We assess older equipment when customers need guidance on whether to repair an existing system or replace it. Our technicians address airflow limitations, uneven temperatures, abnormal noises, frequent operating cycles, and increasing energy costs. Replacement recommendations account for energy efficiency, proper equipment sizing, and compatibility with current ductwork. We stand behind our repairs with a one-year guarantee and offer warranties on parts and labor. Free estimates, financing options, and discounts are available. Our service coverage includes Glendale, Burbank, La Caada Flintridge, Tujunga, Van Nuys, North Hollywood, Studio City, Santa Clarita, and the greater Los Angeles area.

Our team at Orion HVAC handles residential air conditioning needs with repair, installation, replacement, and maintenance services. Certified technicians carefully assess equipment that blows warm air, produces unusual noises, cycles repeatedly, or stops working, identifying the underlying cause before recommending corrective action. We service all air conditioning brands and address both minor component issues and major system overhauls. For new equipment, we help homeowners choose appropriately sized, energy-efficient units, with same-day service, emergency repairs, free estimates, and financing available. 
Orion HVAC delivers prompt residential heating repair, with emergency assistance available when furnace problems cannot wait.

Our pricing is provided upfront with no hidden fees, and every repair includes a one-year guarantee. 
We provide comprehensive seasonal tune-ups for air conditioners and furnaces, helping customers protect their equipment, reduce operating expenses, and minimize the likelihood of unexpected failures. AC maintenance includes refrigerant and pressure checks, thermostat and wiring inspections, capacitor and relay testing, condenser cleaning, and drain and compressor inspections.

These installers are 5-star professionals. From beginning to end, Constantine explained every detail in the estimate & answered my multiple questions in laymen terms. The 4-man team was very thoughtful, polite and protective of my home, landscaping, and personal belongings. I wish every service company worked at these high standards. Too bad they dont do construction and home painting also. I would hire them for both!! Thank you to the entire team.

Orion HVAC replied immediately to my request for service, arriving on the day I made the request. Yuri was prompt and professional, quickly identifying a furnace component that required replacing at a fair and modest price. Orion HVAC are on my speed dial now for future service and upgrade opportunities.

Orion HVAC installed a new Carrier central ac and Heating system for my 4 bedroom 4 bathroom townhouse. The office called me for an ETA prior to arrival, the technicians Tim and Leo arrived on time. The work was completed efficiently and professionally. After the work was completed, they cleaned up the tools, boxes, etc, and left the place clean. Highly recommended company. Thank you!

I had put off having work done on my defective thermostat until the original employee of Orion was available for a follow up replacement service. As it turned out he was NOT the one who DID show up on the delayed scheduled day. The man who DID come out was another man but he did a fine job. Just it could have been sooner but I thought it best the original guy come out. No matter

Thank you Orion for helping me. It was very cold last days and it appeared to be my heater wasn't working. I called couple companies and Orion was the first who responded and send the technician the same day yesterday. I don't have enough words to describe their perfect service. They only charged me the service fee which is less then nothing. THANK YOU!

My air conditioner stopped working on Aug 5,24 so I called HomeServe and they made arrangements with another company. That company never showed up. So I called HomeServe this morning 8/6/24 and they made arrangements with Orion HVAC. They said that they couldn't come today, I told them that I take care of my 81 yr old mom and that the temperature was 90. They said that they would be here by 4pm. And they were. The technician was very nice and fixed the issue. Thank you Orion HVAC for taking care of my family. I will let everyone I know, how wonderful you are and how much you care about your customers. Thank you again for all of your help

Victor was the technician that came out to do maintenance work on our HVAC. We had recently bought the home and wanted to just get more information on the unit while also getting it serviced. Victor was on-time, nice, professional and gave us all the information we needed on our union. Yury, the business owner, was also prompt & professional when I initially inquired about services.
We'll definitely be back for future service with Orion!

The office was very responsive. The A/C technician was thorough and knowledgeable. Although the problem was not resolved the first day, the technician came back 3 days later and was able to get the A/C back working. He worked hard in the heat inside and out for 3 hours the first day and 3 hours the next time, he cleaned and worked through all the components to figure out the issue with my old unit. I much appreciate his diligence and resolve to fix the problem. Thank you Arthur. I can recommend this company for your A/C needs.

Alex at Orion was friendly, courteous and professional. He took his time explaining the issue and when he came back with the part to fix he made sure the job was done right! We appreciated this so much because we have a 21 month old child and needed to make sure we didnt have to do many visits to fix the problem.

Victor and Feliks did great work. They took their time to accurately diagnose and repair the issue with my AC unit that has plagued me for 6 years. They explained to me what the issue was, how they diagnosed as well as how it will be repaired. My AC is now ready for summer. Yury the manager was amazing as well working with AHS to ensure that my system would be properly covered. Ashley and Hannah who work in the office were always ready to answer my calls and very polite. I would recommend Orion to anyone having AC issues. I am beyond satisfied.
