A and R Air Conditioning and Heating

New air conditioning tune up and heat pump Installation. We recently had A and R HVAC Heating & Air Conditioning repair our air conditioning system and replace our older Trane AC unit with a brand-new Carrier heat pump system in San Carlos and Los Altos, California. From the very beginning, the entire experience was professional, smooth, and stress-free. The service technicians arrived on time, communicated clearly throughout the project, and completed the installation and replacement with precision and attention to detail. Our old system was no longer reliable, and upgrading to a new high-efficiency Carrier heat pump system was the perfect decision for our home comfort. Marko and Julian are an excellent team — hardworking, knowledgeable, honest, and always performing at their very best. Their professionalism and dedication truly stand out in the HVAC industry. If you are looking for trusted air conditioning repair, heat pump installation, furnace service, or HVAC replacement in San Carlos, Los Altos, Palo Alto, San Jose, or anywhere in the Bay Area, we highly recommend A and R HVAC. Thank you again for the outstanding service. We will definitely recommend your company to our friends and family!

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.

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 !!!
