Our Reviews

We called 4 Seasons when our heater mysteriously stopped working, right when we had the first serious cold weather the beginning of November. The gentleman who helped us, William, was on time, politely told me the motor in our sixteen-year-old system had gone out, and replaced it later in the day as promised after he picked up a new motor. He even called so I would know he was on the way. The price was unbelievably reasonable- half as much as my monthly PGE. The company could have taken advantage of my lack of knowledge about heating systems. Thank you, 4 Seasons!

This company has the highest level of employees and owners.  They fixed my system and their prices were very reasonable.  Their response was ultimate.  I would highly recommend 4 Seasons Heating and Air over any company for your heating and ac needs.  The best in Castro Valley and by far the best around!

I'm putting these guys on speed dial!  Our air conditioning conked out in the peak of a heat spell.  Not knowing who to call, I checked with Yelp and called these guys on a Sunday morning and left a voicemail.  I wasn't expecting to hear back until Monday but later in the day I did get a call back and was able to schedule a tentative appointment for the following day.  I appreciated a call back on a Sunday and also the flexibility with scheduling an appointment that worked for my schedule.  Monday morning I received a second call to confirm that they would indeed be able to come out and accommodate my schedule.  I loved the friendly customer service and the follow up phone call. Monday arrived and shortly after the scheduled time someone from 4 Seasons arrived and quickly diagnosed the problem.  We were back up and running in less than 30 minutes.  The cost was reasonable and the service was great from both the office staff and the technician.

Very good service. They gave me a time frame of when they will arrive and it was perfect timing. The service guy was VERY professional. He put on booties that I had in my front door and was very well mannered. Overall, very satisfied with my service. Thank you!

We had 4 Seasons Heating and Air-conditioning to check our heating system in the attic of our two story house and were very happy with their service. Several days earlier, a company called BH Bay Air Services had cleaned the vents of our washer and dryer and inspected my heating furnace. It was welcomed as we were not sure it was working efficiently as the first floor always seemed impossible to warm up. BH Bay Air cautioned us not to use the furnace as it might stop working due to the blower was full of dust and that there were no filters on the furnace. The recommended service of vacuuming inside surface of the furnace, cleaning blower components and installing electrostatic filters was $850! Since we were unable to find BH Bay Air Services on Yelp and found positive reviews for 4 Seasons. We called 4 Seasons. The 4 Seasons  technician found the heating system in good working order- no cleaning necessary, no filters needed except in the upstairs hall way, and did not understand BH Bay Air's reasoning for filters in the attic. The technician reinstalled the vent grilles downstairs which had been improperly installed (levers now better able to direct the air) and now the first floor warms much quicker. I requested a new thermostat be installed. Total cost: $185 ($100 for service call/diagnosis and $85 for thermostat and installation). Thanks Yelp!
