HVAC reviews in Covina, California

John was our choice for our HVAC project because he clearly communicated what his team would do, sent a detailed quote, and followed up on any questions we had. During the project, he and his team were prompt, professional, and even did a great clean up job. We are happy we went with Efficient and would recommend John to anyone with HVAC needs.

Leah provided timely communication, and John was very thorough when he performed the maintenance for my HVAC system. I also asked for some photos to be taken on the roof, and they kindly provided those to me as well. Overly, very satisfied with the service.

I would like John and his team. I found them to be so wonderful to work with. They are People of integrity with wonderful work ethics. They communicate well and they stand behind their work. It is an honor to write a review as this is something I don’t normally do.
thank you and all your team.

Great experience from start to finish. Honest, reliable, and professional service. Their work is always done efficiently and with care. I would definitely highly recommend Efficient Incorporated.

I had a hard time getting other companies to even show up, but I’m so glad I found Efficient Incorporated. From start to finish, the experience was smooth and professional. John, the technician, was on time, knowledgeable, and explained everything clearly. The quality of work was excellent, and it’s rare to find a company this reliable. Highly recommend Efficient Incorporated for anyone needing HVAC service!

It’s nice to know I can rely on the reliable and honest service that Efficient Inc provides. I got a reminder message that my system was due for an annual maintenance, and with work schedules so busy, Efficient Inc. booked an appointment time that worked with my availability. Abraham, the AC tech was very professional and explained the process every step of the way.

Efficient Incorporated was very kind and willing to try and repair our commercial AC unit when many other companies refused and recommended we replace it. They were very responsive and the technician helped explain everything. The work was done in one day even with a few extra things we added. Our AC is working great and we will be calling them for any of our AC needs.

Heaven sent!!! Jon did not try to up sell me for my repair he gave me an honest quote to get the job done!! I can't begin to express how grateful and blessed I feel to have met Jon and Efficient Incorporated!! Honest, reliable, trustworthy, quick, compassionate, and just simply the BEST!!!! If I could give 1 Million stars I would 5 stars dosent do justice!!! I highly recommend Efficient Incorporated to anyone looking for a honest contractor to get the job done fast!! Million thank you to this company!! The world needs more honest and good humans like Jon and the Efficient Incorporated team!!! Gob Bless!! and Thank you! Thank you! Thank you!!

I found Efficient Inc through a manufacturer’s website and asked them to replace a AC compressor at a rental property. They were thorough and communicative throughout the entire process and the price was reasonable for the work they did. I’ve used them at other properties since and I’d recommend them with no hesitation for any HVAC needs.

Efficient Inc. inspected an older central heating system and provided options for adding central cooling. Both the office staff and the technician communicated effectively and were very accommodating about meeting a tight schedule. The technician was knowledgeable and thorough--I could tell he was looking carefully at this particular system and not just giving me generic answers. I am not moving forward on this project right now, but I will definitely be calling Efficient for work on other properties.

Efficient Incorporated and John with his entire team have gone above and beyond to provide us with an excellent AC system for our home. From start to finish, the process was handled with true professionalism, care, and attention to detail.
They are reliable, trustworthy, extremely hardworking, and clearly take pride in what they do. Communication was clear, timelines were met, and the quality of the work speaks for itself.
I can highly recommend Efficitn Incorporated to anyone looking for a top-level HVAC company you can truly trust.

My AC was blowing out warm air so I decided give Wintri a buzz. They were able to fit me into their schedule and got to my house by the end of the day to take a look and diagnose the issue. Zach showed up and was very professional and got straight to work. He found the issue, replaced the part, and had my AC back up and running very quickly. He also replaced my filter and recommended I change it more often. Any time I have AC or heating problems I will definitely be using these guys!

We had a positive experience with Wintri. They were able to come to our home early in the morning and fix our AC problem. I definitely recommend this company and will continue to work with them should we have any further issues. Thank you!!

Zach diagnosed the issue and presented the options and the costs, and the pros and cons of each. I appreciate his honesty and technical knowledge. The prices he quoted were reasonable as well. I highly recommend this company.

Have nothing but great things to report about Wintri HVAC! The guys showed up on time….got right to work…..protected the pathway to the heater inside the house and removed all of the old units….hvac total….were pleasant….and the BEST part….the heater and the A/C worked on the first try!!! So if you are ready to make an upgrade to your HVAC, Wintri will be a great choice!

I installed a 1.5 Ton (18,000 BTU) in my daughter's home. Zach Taylor estimated the cost of installation, arrived on time, and was eager to secure my business. He was professional, and managed to arrange installation for the following day. The installation was seamless; the unit looks beautiful in the home, and equally as important is the clean and professional look of the electrical and other lines required to operate the unit. Wintri hid the lines underneath a well installed aluminum cover that gives the finishing touch required for an amazing look. I would highly recommend their services. Thank you, Wintri!

Very satisfied with the service! Gave a fair price for the work done and were very responsive. They even provided a portable AC unit while waiting for parts on order to arrive. Zach and crew were awesome!

Edit: Just had my new unit installed by Wintri and couldn't be happier! Fernando was quick and efficient, I barely noticed them working. The new system has been amazing so far and everyone I have spoken with at the company has been extremely courteous, helpful and professional.
So happy with the service! They were able to squeeze me in within an hour of my call. While my issue turned out to be $$$, the tech really took his time to explain the pros and cons and answer my questions. So pleased with the service!

Angel did the diagnostic/estimate and he definitely lived up to his name! Super friendly and informative. Respectfully covered his shoes and didnt leave any mess. He explained everything in detail and answered my many questions. Came out fast and on time, and went through the many different options. Appreciate it!

Fast and professional service, Salvador is polite and knowledgeable A+ technician, he took care of the job immediately and recommended future service. Shoutout to Mariana effective and efficient customer service. Thanks to you all.

I feel that this company doesn't try to steal your money. Our technician, Zach, has been wonderful and honest since he started working with us. Our AC is doing great.
