Heating & Cooling in the GREATER San Fernando Valley, CA

When our AC stopped working we chose MightyServ because they were the top authorized dealer for our Carrier system. They exceeded our expectations and we will now work with them on a regular basis to maintain our HVAC system. Each technician and phone representative was professional, respectful and eager to help. We needed a specific high-tech part replaced by the manufacturer and MightyServ followed-through in a timely manner to complete the job. I also really appreciated that MightyServ texted a photo of the technician that would be arriving as an extra safety precaution. Thank you so much, MightyServ!

These guys are the best! Wouldn’t use anyone else. Brian was honest and professional and got us cool right away!

Great service, communication and cordiality. Technician and front office are very helpful and friendly.

Brian was fabulous. Explained everything clearly and took the time to come up with clear solutions..

Brian was a super service representative. He went above and beyond in his service. We are very grateful for Mighty Serv!

Alex is an excellent technician! He came out right away and quickly resolved the problem. He was friendly and extremely knowledgeable!!

Technician was very thorough and efficient, very nice, and explained our service visit. He was able to get the parts and fix our unit the same day. Thankfully the repair was under our warranty.

I have a maintenance contract with Mighty Serv. Jose Martinez arrived exactly on time and was 100 percent professional and very knowledgeable.He showed me how to reset my Nest thermostats, helped me order the correct filter for my unit on Amazon and wrote a thorough report on his findings and the work that he did. The best part is that because I have a maintenance contract the visit cost me nothing. Karen

They are the best to deal with

Jose showed up on time. Professionally did his job. Was friendly.Completed his task quickly. Thanks again.

Can’t say enough good stuff about the MightyServ team. The staff is always friendly, courteous and on time for appointments. I signed up for the maintenance program and they proactively reach out to set up appointments to make sure my system is keeping us cool during the summer and warm during the winter. Thank you MightyServ.

Nathan was very professional with the service and punctual. He was courteous, knowledgeable & I was happy with his overall performance. 5 Stars.

On time - highly competent - very thorough checkout - no complaints. Always fine service - on time - fast - friendly.

Reliable and reputable company. They checked in first thing this morning and then called 30 minutes before they got here.

Outstanding service from start to finish! I called around 9 AM, and by 11 AM they had a technician at my house. By 11:30, the problem was already fixed! Mynor was professional, friendly, knowledgeable, and took the time to explain everything clearly. I was genuinely impressed by how fast and efficient the entire experience was. It’s refreshing to receive this level of customer service. Couldn’t have asked for a better experience. I’ll absolutely use MightyServ again and highly recommend them!

Outstanding rep for your company. Very professional, knowledgable and respectful

After more than 15 years as loyal customers…starting when they were Canoga Park Heating & Air…we continue to receive top-notch service and excellent quality of work from MightyServ. Jeremiah was punctual, professional, friendly, and very knowledgeable. We highly recommend them!

Excellent technician and staff.

Professional and quick

Jeremiah was very thorough and professional.

MightyServ did a fantastic job with the HVAC installation at my home. From start to finish, they were incredibly professional, punctual, and thorough. Leal took the time to explain every detail of the system and answered all my questions with patience and clarity. The installation was completed right on schedule, and the quality of their work really shows. I couldn’t be happier with the service and highly recommend MightyServ to anyone looking for reliable HVAC professionals!

Marlon spent extra time and effort on improving insulation and cleaning the unit of debris.

Rodrigo AKA Rigo arrived early, before 8 am which was welcomed. He was friendly and professional during his visit to service my heater and check the AC portion as part of the bi-annual maintenance on our residential HVAC system for the upcoming winter (El Niño currently in our So Cal weather forecast). He informed me that he would be turning off and on the air conditioner to test that part of my system as well. Once completed Rigo clearly explained what he found and shared photos he had taken of my system during the testing and inspection process. The office staff is also great at scheduling my bi-annual appointments. With the new no hassle scheduling they called me the evening before my service to let me know the Tech (Rigo) is was making me his first call and would arrive around 8am which he did. I have used their services since the early 2000s and recommend MightyServ for anyone seeking annual maintenance or new installs. Thanks for providing great service and repairs. Alex

Kevin from Mightyserv was here to give me an estimate to replace the condensor in my A/C system. He was prompt and very through. He gave several ways to go and gave a good explanation of all the options. I have used this company for over 30 years in several residences. They have always been truthful and honest and do excellent work.

They are absolutely exceptional!!!!! Aside from doing a great job, with they are so organized and make you feel safe by calling to make sure you know who to expect etc. Shawn Flores the gentleman who was sent to our house delivered a 5 star job, going above and beyond to take care of every detail. I highly recommend them!!!

AC went out in hottest days of July. Eddie came out and trouble shot the problem and repaired it. It is cool again!

The service was part of my service agreement, and the seevice today went great, the technician showed up on time and was professional.

On time, very professional and explains everything as needed.

Excellent and knowledgeable service

We were concerned that the A/C was broken but it was a clogged pipe. Jose identified the problem right away. A/C is working smoothly now!

Brain was absolutely well mannered and very professional and was a delight to talk to

Shawn was very knowledgeable and very friendly, helpful and honest.

Jose showed up on time, and performed routine semi-annual maintenance. He was very professional and was very polite and pleasant. The service was excellent.

COMMENDABLE SERVICE CAME OUT THE SAME DAY FIR AN EMERGENCY...GREAT CUSTOMER SERVICE!!!!

Very happy with the service Brian was very . professional.

Had air check, did an excellent job, were clean and quick. Thank you!

Excellent through service.

Very happy with promptness, knowledge and no-nonsense repair work. Def recommend!

Nice people, good service

Collin was polite, respectful and very patient in explaining the functioning of my heaters. He’s an asset to your company. Please pass on my good thoughts about him to him.

Shawn was personable, knows what he needs to do the job

Very knowledgeble in the HVAC systems. Very courteous & well mannered. Best wishes!

I have consistently used Mightyserv for myself and three rentals, and the company has been great on every service call. Today, Alexander completed a service call after my tenant reported water leaking under the system. Alexander was great in communicating with me about his finding and what he did. He made good recommendations going forward.

I had a specialist come out for lack of airflow in a particular room, and general maintenance, and I had Rigo at my house. His explanation of everything going on, where he was at in the process, all of the findings and issues I had were very clear, with photos. He then came back with a solution that was fairly priced, and very much fixed an issue I didn’t even know I had. My air conditioner is working much better now. Rodrigo had amazing customer service skills. He was polite, nice, clean and willing to go the extra mile even in the summer heat.

Alex identified the leak with the condenser drain line and corrected the problem. He was patient and very helpful. We will request that he does all future service.

Could not be happier than I am! Brian was most professional, polite, accommodating, and thorough. His patience and kindness was exceptional. The entire process from my first original call to completed job was effortless and expertly executed. Every time I use them, the experience is superb!!

Courteous and well trained technicians. They always provide a detailed report of work andcservice provided. We have used and trusted Mighty Serv since 2008 when they installed out HVAC unit !

My or was very professional and positive. He explained and showed me in my unit why my condenser needed to be replaced.

HE WAS PROFESSIONAL, CHECKED WHAT WE THOUGHT WAS THE THERMOSTAT AND AGREED IT WAS THE THERMOSTAT THAT WAS CAUSING THE FAN FROM BEING ABLE TO TURN OFF. THE NEW THERMOSTAT OFFERED WAS TOO EXPENSIVE AND NOT SOMETHING I COULD AFFORD TO PURCHASE AT THIS TIME.

Marlon was very professional and informative. I feel he did a very good job.

Very nice tech and did his job well

Arrived on time for scheduled maintenance appointment. Technician was friendly and exhibited a very professional demeanor. He conducted a comprehensive evaluation of HVAC and determined no issues exist. Thanks for the great service.

Did great job, honest, provided information needed.

Shawn was incredibly communicative, efficient and overall just very pleasant to work with. Would recommend this company and this technician.

Marlon was prompt, professional and answered all my questions. He mentioned that they are one of the few remaining small businesses that are not acquired by equity firms. We like to support small businesses because they take pride in what they do. Yes, I recommend this business to everyone.

Fast efficient! Wow These are good guys and - very professional. Hey diagnosed my issues in an hour. Turned out to be an over pressurized system. Too much coolant. Apparently there is a sweet spot for refrigerant coolant. Mine had too much. Thank Jose He’s really good.

Excellent service!! Kevin clearly and throughly explained what was wrong, what was needed, and how he solved our problem. He also explained how we should use the appliance to prevent over loading it thereby prolonging the life of our AC unit. We will request him next time we have an AC or heater issue. Excellent!!

Excellent service. Thanks.

I've dealt with 6 different HVAC companies in the Los Angeles area thus far and MightyServ blows all of the other companies out of the water. Amazing service. MightyServ is transparent and don't try to upsell you on parts that aren't actually broken like other companies do. The only company that actually respected my home by protecting the floor with a mat and shoe covers. Actually on time. Showed up the same day I called. I had Nathan come to my apartment to service my HVAC unit and he was training a technician. Both couldn't have been nicer or more professional. I would recommend this company over any other in the Los Angeles area.

Leal, Eduardo, and the whole MightyServ team are absolutely awesome. We bought two heat pump units for our property earlier this year and it has been a great experience. They are everything we expect from a business: transparent on service and pricing, communicative on scheduling, punctual on services, and all-around professional. Leal walked us through exactly what we were buying and provided all the documentation needed for our rebate. Eduardo and the team executed the installation, inspections, and commissioning of units. Since the installation, we have needed some things addressed and the MightyServ team had a technician come out the same day. Same. Day. They have earned our full trust and confidence.

Excellent installation and Exceptional maintenance of our Carrier heating and air conditioning system. We had the UV air scrubber installed recently and it works great! If our system fails for any reason, we have priority access to an HVAC technician. (I believe our system has never failed because we purchased an excellent system and we have regular maintenance.) Marlon Gonzalez is our recent maintenance technician. He is an example of the reliable and experienced people who are employed by Canoga Park MightyServe Heating & Air Conditioning. Marlon’s knowledge and expertise is professional in every sense of the word!!!!

Brian was awesome. He was professional and knowledgeable. I appreciate the service.

Punctual,friendly honest service..Brian was great to have as a technician.

Everything perfect. Thanks.

Very customer friendly, great technician, on time, takes pictures of work done and price is reasonable.

Alex was professional, efficient and knowledgeable. Very friendly.

Shawn was great. He was very pleasant and completed the work quickly.

Excellent response from the company, explanation of different options of service, immediate scheduling. Serviceman Shawn Flores arrived on time, performed all necessary checks, explained condition of the unit in details, was very professional and courteous

Shawn was very professional, knowledgeable and super friendly.

Great attitude and knowledgeable tech. Always very helpful and informative. The AI on your phone system leaves a lot to be desired.

Brian was extremely helpful and resolved the issue with my AC very fast durning this heat wave we are having.

I found Nitin to be very professional, thorough and I felt that he had my best interests at heart., It surveyed my entire unit and he came up with several ideas that will make the system perform better. I was very impressed by his passion for his job and he offered me great advice oh how to make my AC system perform as well as possible. Nitin is a very valuable asset for your company.

Job well done

Excellent customer service from Rodrigo Garcia. He was kind, efficient and a professional who explained every detail to my satisfaction with photos. I request his service on my next maintenance appointment. Thank you.

We appreciate Rigo's skill level, communicating everything with us clearly Warm and easy to talk to. Trustworthy.

Shawn was terrific. He showed up on time, was courteous, took the time to explain the problems, was extremely knowledgeable, and seviced my air conditioner!

Shawn, the HVAC repairman is Fantastic!! Was not familiar with Mighty Serv until yesterday when I met him while he was doing the Inspection for a home I'm purchasing. He was so knowledgeable, professional and comprehensive, so I actually scheduled service for my current home today. He just left and once again, great job! Thanks so much I will absolutely use your service in the future!

Henry was knowledgeable, listened to understand our needs and provided.a solution to meet those needs.

Excellent service tech

I had a very positive experience with the technician! Which i always have since I started having them come out! I have recommended them to anyone who asks me where do I get my A/C serviced at!

Nathan was very professional and knowledgeable, he explained in detail what was wrong. He advised me what steps needed to be taken to repair the AC unit. Thank you Nathan for taking the time to answer all my questions.

Amazing people and work! Installed new HVAC system and the everyone on the team (Ulysses, Daniel, managers, the crew, Felipe) was wonderful. Very understanding and did everything they could to make sure we were happy. This is after getting 0 help from this company called RELIABLE ENERGY (UN-RELIABLE Energy should be there name).

Preventative maintenance is a good thing. Brian came out today & ran a comprehensive service on our AC unit and all is good. Courteous & professional service.

I have used Mighty Serve for a year now. Today Shawn arrived on time and ready to go during the torrential rains this morning (2/16/26). Shawn took care of 2 Furnaces. One in the attic and one in the garage. Shawn asked me if I wanted to have the filters changed before going ahead without asking me. I liked that! Shawn showed me the filters which indeed needed replacement. Shawn was efficient, knowledgeable, polite and held a professional albeit friendly attitude. I would definitely recommend him as well as MightyServ Heating & Air Conditioning. .

These guys are really good and they have amazing customer service. They are always on time, they confirm the day before call you when they get there and the techs are always very respectful.

He is very respectful and helpful. Work well done!

It’s been a pleasure to be a customer of MightyServ from the moment I asked for a quote to replace my aging Heating & Air system back in August 2023 to todays Maintenance & inspection service. I consider this company and all its employees to be of the highest caliber providing quality services. I give them a 5 ⭐️ recommendation

Brian Barrera from MightyServ came out right away when I called because my air conditioning was not working. He was very diligent and carefully inspected the available power, the thermostat and the A/C unit itself which was on the roof of the condominium building. He explained his findings and communicated his recommendations. After his made the required repairs to get the air conditioning working again, he evaluated the system to see that it was working well. I would definitely use MightyServ again. I think that Brian was very competent and responsible.
