HVAC reviews in Spring Valley, California

Mario did a great job installing our mini split with two ceiling cassettes. He was communicative and efficient as well as clean.

Temo was awesome at diagnosing the system and even getting it to work before our session was over, even if there are other major issues that still need to be dealt with. He was also great to work with and approachable as well.

Awesome company, small very honest business!
Had them replace the furnace and ducting in my rental property. They beat everyone on pricing and did a very clean job. I highly recommend them for your HVAC needs.

Blue Collar Technicians Temo & Mario are very professional, knowledgeable and very accommodating,
I will highly recommend Blue Collar for any residential & commercial installation, repairs and maintenance.

Keep up the good work guys!!

Very professional employees. Temo was very helpful and knowledgeable. I highly recommend Blue Collar for your HVAC service!

Very clean work! Everything went exactly the way it was explained to me. These guys were very professional and polite. They left my house clean and worked around me and my pets being home during the install. They did a full AC/Heater and additional mini-split .. it works awesome!

My Real Estate agent referred me to him while selling my home. Got quotes from other companies and they all said that the system had to be replaced with new duct. Blue Collar HVAC found the root of the issue and fixed it in one day. System is still good for another 5+ years. I sold the house with no delays and the buyer was extremely satisfied. I was extremely pleased with their honesty and hard work. Definitely recommend them!

Hands down, Blue Collar takes the Gold Medal! From my initial contact with the incredibly knowledgeable and experienced Temo, to the outstanding, organized, and detail-oriented Cassandra, and the efficient and experienced installation team with Alex, Mario, and Temo, I received the best customer service I've had in a very long time. As an independent woman, it is important to me that my questions are answered and my concerns addressed with respect and trust. Temo really took the time to find the best system for my home and answered my questions with patience. Cassandra ensured details that were important to me were addressed, and communication with the installation team was excellent. The whole team is friendly and professional....I've already recommended them to friends! Bonus points that I was able to give my business to a hardworking and honest small family business!

We needed to upgrade our ducting-- Blue Collar came in with a great price and knocked it out fast-- we are all set to stay cool in the summer and warm in the winter. Marco and Lam were exceptionally respectful and hard working.

It was a pleasure to work with Temo on a service call to see why our wall heater was not turning on. Temo was knowledgeable and professional. He was able to fix the issue even though it appears the issue was my partner and I 😅. Would highly recommend this company!

I highly recommend Blue Collar HVAC. All of the people I have talked with are polite, helpful, and efficient. Temo did an excellent job and obviously cares about clients receiving great service.

The team (led by Mario) with Blue Collar HVAC that installed a new furnace and coil in the home were fantastic! Professional, efficient, experienced, and knowledgeable. Thank you! I will definitely recommend Blue Collar HVAC to neighbors, friends, and colleagues.

Excellent customer service from beginning to end! Very friendly customer service from Cassandra and Temo. Cassandra was very friendly when I called to book a disconnect appointment for our condenser. The day of the appointment Temo was very friendly and knowledgeable. Will definitely be using their services again.

I recently had the pleasure of working with Blue Collar to install a multizone mini-split system in my house, and I couldn't be happier with the entire experience. From start to finish, Temo and his team demonstrated a level of professionalism and expertise that far exceeded my expectations.

First and foremost, the contractor's workmanship was truly exceptional. Their attention to detail was evident in the thoughtful manner in placing the equipment and the mechanical/electrical runs that are aesthetically pleasing, seamlessly blending with the overall design of my home. I appreciate their dedication to not only functionality but also the visual appeal of the installation. See attached photos.

Moreover, the project was completed on time and within my budget. They were efficient, organized, and transparent throughout the entire process, including assisting me with getting HOA approval and the city’s final inspection passed. Their willingness to go the extra mile to ensure a smooth experience truly impressed me.

They helped me with proposing a high-efficiency Bosch equipment to meet my home needs, budget, and Federal Tax Credits eligibility. I appreciate their dedication to sustainable solutions and their ability to offer top-notch equipment that aligns perfectly with my needs and budget.

Overall, I wholeheartedly recommend Blue Collar to anyone in need of exceptional service, outstanding results, and the best value. Their professionalism, attention to detail, and commitment to customer satisfaction truly set them apart. I am beyond satisfied with my mini-split system installation and will not hesitate to engage their services again in the future.

Thank you once again to the entire team for their exceptional work!

Temo, Mario, Eduardo znd Cassandra were fantastic. They came on a Saturday do to an emergency situation and removed and installed a new electric HVAC. They are very professional, friendly and funny. They kept the place clean and I will be calling on them again. Thank you Patrick 😊

Bravo to Blue Collar HVAC! For fast, clean, professional installation of our new 2 Stage Trane Furnace with UV Light Air Purification. This furnace qualifies for the tax credit because of it's 97% efficiency rating. Super nice people too! Temu, Mario, and Alex were all super helpful!

Temo came and inspected another company's HVAC installation. He was extremely professional and knowledgable. His inspection notes were impecable and he was empathetic to my situation. I could only assume his work is just as excellent and will definitely support and promote his business. Cassandra was also fantastic at booking my appointment. Thank you BC HVAC!

Had our HVAC system serviced yesterday (12/12/25) by Lalo. He did a great job, the kind of service you hope for in any customer situation. The service turned out to be a bit more complicated than anticipated. He could’ve easily done the basic service and asked me to schedule a more in depth maintenance service at a later time. However every issue was identified and taken care of before he left. I really appreciate that. You guys did great as a company as well. Thank you.

Temo was great. Honest man doing great work. I wish I would have found Blue Collar sooner. Fast and meticulous work from a great family owned and ran business. I can’t say enough about them. Will be recommending them to everyone I know. Use them you will not be sorry!

Cannot say enough good things about Temo and Blue Collar HVAC. From the first time Temo came out to inspect our HVAC setup, he was super knowledgeable and honest with what he recommended. For the work, him and his team were on time, did great work, were super friendly, and provided me with updates throughout the day. I will always come back to Blue Collar HVAC for any additional services I need.

I had an excellent experience with Blue Collar HVAC from start to finish. Their work was high quality, affordable, and completed in a timely manner. Communication was outstanding — they kept us informed every step of the way, answered all our questions, and were always responsive. The team was professional, knowledgeable, and respectful of my time and property. It’s rare to find a company that combines great workmanship, fair pricing, and clear communication. I highly recommend Temo and would absolutely use his services again.
