Kevin from Sierra came to our house to find the best thermostat that will fit our needs He explained on how they work and sold us on one of the brands we were thinking about He was pleasant and answered any other questions I had I will request him from now on

I had a new HVAC system installed in my home by Sierra Air Conditioning & Heating in June Everyone involved from office staff to installers and technicians have been very professional They have followed up, after the original install, on several occasions to make sure the system is running properly I appreciate them being proactive and calling me instead of me having to call them I wouldn't hesitate to use them again in the future

Tyrone is great! Tyrone did a complete check up of our two HVACs and even replaced a failing capacitor in one of themVery friendly, clean worker and expertly qualifiedRobin did a super job of scheduling Tyrone's visit so he could come earlier than planned!

Wayne was a professional and was considerate of my home, by wearing shoe covers, covered the floor before putting his ladder on it He took pictures of the heater he was checking on, so I could see what he was talking about He had previous notes on the previous visit to my home, so he knew what he had to look at again Sierra a/c and heating is a good company, I repurchased another year of them to come out and watch over my systems

I had Sierra Air-conditioning to our home to do the winter service of our furnaces and I also had them service my water heaterMatt did a very thorough and complete inspection of our heating units and made sure they are operating at maximum efficiencyMatt also drained my water heater, changed the anode and cleaned and adjusted the flame so it also works at maximum efficiency
Matt was a great representative of The Sierra Air- conditioning brand and he explained everything before he did anything
I would highly recommend Sierra Air- conditioning, you will not be disappointed!

On July 4th I had Silverstate check my 4ton unit - compressor was going bad They installed a new Maytag 4ton seer Once complete when I went to bed I would wake up sweating Temperature rose 3-degrees I had them out three times with their most senior technicians and they said the coolant was perfect, but I still kept getting hot
I met someone a Costco selling Lenox A/C's and asked them if they could send out their best technician They sent Frank out, he was here close to two hours it seemed and found out I was low 1/to pound of coolant based on a sub cool number He was very meticulous with his coolant monitoring equipment and very patient to make sure it was perfect
The results are my A/C now works perfect, no more sweating and I did not even have to low the thermostat at night What a relief! From now on I only what the people at Sierra to work on my unit Thank you guys for ending a month long problem on a brand new unit!
