What Foster City customers say about local pros

the technicians helped with a small commercial install and kept the process calm and organized. they coordinated access with our manager, protected the work area, and kept tools contained so our staff could keep moving. they explained the plan, then completed the installation and testing in a way that felt careful. i appreciated the clear estimate and the simple closeout notes. they also verified the unit was calbrated correctly and that the settings matched our operating hours. cleanup was complete and they hauled away packaging and old materials. the follow-up email included model numbers and a service schedule, which helps for our records. overall it was a steady, professional experience and the space has been comfortable since.

I used Air Conditioning Champ for a small commercial suite where the air felt uneven between rooms, and they approached it like a real diagnostic job instead of a quick patch. The crew checked the registers, measured temps, and looked over the control wiring before suggesting changes. They explained why teh back office was staying warmer and proposed a couple of solutions with prices up front. What stood out was the pace: they didn’t drag it out, but they also didn’t skip steps. After the work, they tested each zone, verified the fan settings, and made sure the noise level stayed reasonable. Cleanup was handled well, no dust piles or loose tape left behind. The office manager appreciated the clear invoice and the way they coordinated access around our client appointments. We also got a follow-up email with maintenance reminders and a contact line for any questions. Everything felt handled with care and consistency.

The technicians handled a cooling issue that had been bothering us for weeks, and the process felt well thought out. They listened to the symptoms first, then checked the outdoor unit and the indoor coil rather than jumping straight to a replacement pitch. When they found the likely cause, they explained what it meant and how it affects performance, including what happens when refrigerant is low and why that can show up as longer run times. The estimate was written clearly with labor and parts separated, and they didn’t rush me while I reviewed it. During the work, they covered the floor, moved equipment carefully, and kept the noise down as much as possible. Afterward, they tested the system, confirmed the temperature drop across the unit, and had me stand with them while it stabilized. they also answer my questions and was patient even when i repeat things, and the office person call back quick which help alot. Overall, the repair felt thorough and the house has been comfortable since.

Only one experience with them, but I'll be back. Needed a simple bit of tin work done and not only did they do the work as I was driving over, they helpfully provided a second piece of the same dimensions - and at a fair price. Another local HVAC provider needed a week and wanted to charge the earth for this simple job. Thank you Bayside Mechanical!

I made an appointment with this company. To make the appt, they asked for a credit card? The lady on the phone was not friendly at all. The day of the appt. nobody showed up during the 2 hour window. I called and the same women who took the appt. answered and gave me a BS excuse, why nobody showed. She lied about not having my number, even though I gave it to her when I called 2 days prior. Terrible/ dishonest business, stay away!

Best HVAC heating and air conditioning repair company in San Mateo. We ask 3 companies to give us a estimate on what we needed. We have a business location with 4 roof top 5 ton air conditioning systems. Two companies told us we should replace all 4 units. They are only eight years old and that did not sound correct. Bayside Mechanical was the only company who said there was nothing wrong with the units that a general servicing would not correct. $483.00 later we were fixed and have been very happy for the last 3 months. They saved us $20,000 plus. We love Bayside Mechanical.
