I called this "business" to book an appointment and I got a really weird reply. The guy who picked up kept saying "the business of what" over and over again, but in a zesty, flirtatious voice. This made me really uncomfortable, did not answer my questions about services, and gave me a hard time. If 0 stars was an option, this "business" earned it.

⭐️⭐️⭐️⭐️⭐️ Outstanding Service and Quality Work

I hired this company last year to replace the ducting system under my home and upgrade both the heating and air conditioning systems, which were over 40 years old. From start to finish, the experience was excellent, in woodside California.

The service technicians dedicated over a week to the project, making sure everything was thoroughly cleaned, properly installed, and functioning perfectly. Their attention to detail and commitment to doing the job right really stood out.
Since the installation, the air conditioning has been working flawlessly, and the heating system performs exceptionally well — the comfort level in my home has improved significantly.

More recently, I had them return to replace my attic fan and seal all openings to prevent mice from entering the attic. Once again, their work was precise, clean, and highly professional.

I’m extremely happy with the entire team. They are knowledgeable, hardworking, and truly care about the quality of their work. I highly recommend them to anyone looking for reliable HVAC services.

Excellent HVAC service in Sunnyvale, CA! Highly recommend for anyone local looking for air conditioning repair or heat pump installation.
Last year, this company fixed a leaking condensation issue in our attic, and this year they helped us again when our old 23-year-old Trane furnace started making strange noises and giving off gas-like odors. They quickly found the problem—a rusted and unsafe heat exchanger that needed replacement.

We upgraded to a new all-electric Trane heat pump system, which is perfect for our home in Sunnyvale, especially since we have solar. It’s energy-efficient, quiet, and a huge improvement overall.
The team was professional, clean, and easy to work with from start to finish. If you need HVAC repair, furnace replacement, or energy-efficient heat pump installation in Sunnyvale or nearby areas like Santa Clara, Mountain View, or San Jose, this is the company to call.

Support a reliable local HVAC company—you won’t be disappointed! I’ll definitely keep recommending them to neighbors, friends, and family.

I’ve trusted this HVAC company for over 25 years, and they continue to exceed my expectations every time. In an industry where many companies come and go, their longevity and consistent quality truly stand out. Their CSLB record is excellent, which gave me even more confidence in choosing them again.

They originally installed my Trane air conditioning and heating system and recently upgraded my home with a brand-new Carrier Infinity heat pump system. The new system is incredibly quiet, energy-efficient, and delivers perfectly balanced heating. I’m excited to experience its performance during the summer months as well.
Their team also sealed the ducts and vents under my home in Atherton, which has significantly improved efficiency and airflow. The attention to detail and professionalism they bring to every job is impressive.

If you’re looking for reliable HVAC services in Atherton, Menlo Park, Palo Alto, Redwood City, or surrounding Bay Area communities, I highly recommend this company. Their customer service is outstanding, and they truly stand behind their work.
I came back to them because they earned my trust—and once again, they delivered exceptional results.

Marko is Awesome ! I have an original 1940 floor furnace. He said it would be $7500 to replace but he was able to rebuild it and add a thermostat to it. It originally just had a on/off valve. He did a beautiful job and cleaned up everything spotless. Super nice guy and a very reasonable price. Heater works perfectly. I highly recommend him. Great experience !!!

Excellent HVAC Installation & Service in San Jose, CA
We recently replaced our old Carrier heating and air conditioning system with a new Trane variable-speed heat pump system with electric heating. Our previous unit was over 30 years old and had needed several repairs over the years, so it was time for an upgrade.

The technicians did a great job throughout the entire process. They removed the old equipment, installed the new system, replaced the supply and return plenums, and insulated exposed ductwork. They also updated the electrical panel with new breakers and fuses.

Everything was done cleanly and with attention to detail. As an added bonus, they painted the HVAC closet while it was empty, which we really appreciated.
The price was in line with other quotes we received for similar equipment and work.

Overall, we are very satisfied with the installation and the professionalism of the team.
Thank you for the excellent service.

This is an outstanding company! They had installed our whole HVAC system as well as a min split in our backyard cottage, several years ago. Recently they have come back for additional support. Rats in attic had eaten away at the wires. Marko took control of the situation and within a short time everything was working again.
He is wonderful to work with and gets the job done right!

Pretty expensive. I ended up spending $914 (labor + parts) to fix the furnace gas valve. I was looking for the same day fix. But if you have time, I suggest to get a 2nd quote.

They came on the same day, within a couple of hours, in the evening. Did a great job. I will be using them anytime I need service. Professional and very fair on pricing. Thank you so much!!!

same day repair, good job
