Good Work but...................




Review of Certified Heating and Air Conditioning

The work was done as told and promised. but the work place was not cleaned and messy, They broke the attic cover panel and did not bother to fix it. But they are very prompt in collecting the payment. They can still do a better service.

Tyler was great!




Review of Certified Heating and Air Conditioning

Had a tune up special and Tyler identified an issue we didn't know we had. Not a giant expensive fix, but a small issue that over time would have caused problems. Same day appointment, super pleasant office person on the phone, simply excellent. Will use you guys again. Thank you!

I am in Fremont, California to discuss replacing central gas furnace and air conditioning systems with high efficiency heat pumps. We discussed technologies and efficiencies of new equipment. I was also able to get his current system running in the meantime.

Here on day 2/2 with all the challenges and corrections that had to be made in order to fix things, we will need another day to complete. But with the hard work put in today, we got the duct work started, all boots cut in, new return cut in, all rough patching work was completed, and we installed new tstat wire and tstat. We will only need a half day to finish it all tomorrow

Today we were here in the Fremont area performing a furnace and duct work replacement. This will be a multi day job, and on day one we got all old duct work and old furnace tore out. The new 2ton furnace set in the attic and removed 2 wall furnaces. Ran in to some major electrical issues due to the house being built in the 50’s. But after fixing the issues the clients will be at ease knowing that they will be safe until we return Monday morning to do duct work and patch work
