Job Well Done by Him
I wanted to leave a 5-star review for Raul, service technician with Environmental Heating and Air. He did an outstanding job servicing our furnace and went the extra mile in cleaning air grates, installing our air filter, and making sure all screws were bolted tightly. Job well done by him!!!
Marc Keller

Jim Schellentrager
A Fountainhead of Knowledge
Jonathan Monzo, senior service technician, is a cool professional. This was my first maintenance on my Lennox furnace and he went over every step with great zeal and passion. It's nice to know that EHAS has great individuals who care and get the job done efficiently with know-how. I appreciate his work ethic too, and he told me I could call him anytime if I have a question. He is quite experienced and a fountainhead of knowledge.
Anthony C. Bersamin

Very Professional Company
This company is very professional. They arrived on time and took care of my water heater, which wasn't producing any hot water. I will definitely use them again.
Carlos Sueldo
He did a great and thorough job
I definitely take back any derogatory comments I made before about this company. Zack was at my house for a while today trying to find out why I have high humidity in my home, and he did a great and thorough job. Super frustrating to have a brand new home that is so uncomfortable to live in. He knew HRV and modern systems really well and found more about my system than I previously knew. Definitely call this place if you have a situation or problem of unknown cause or origin.
Paul Bradbury
Thoroughly Impressed Since the Start
We booked Env Heating & Air through Costco and have been thoroughly impressed since the start. They installed a new furnace for us, replacing a model from 1973! They also went above and beyond and fixed several leaks in the old ductwork, which other companies quoted us thousands to do. They tested the system repeatedly, built a new to-code furnace platform, and were great at explaining everything they were doing and why. Raul and Jefferson were our techs for the install and if I could give them 6 stars, I would.
T. Caires
Absolutely amazing and highly professional
Eddie and his assistant were absolutely amazing! They called me and told me they were coming. They arrived early! They were professional, courteous, respectful, and knowledgeable. They explained the procedure and set expectations about the installation. Quick pause and shoutout to Melody from Elk Grove Costco, who has been saying hi to me since before 2022, encouraging me to get a free estimate. And when I said OK, the nicest guy, Chris the sales representative, came knocking at my door in 2022 and in 2026. Also very friendly, knowledgeable, and thorough.
Back to Eddie and his assistant - they were clean, laser-focused, and efficient. Altogether, the installation took 2 days, but it was such a highly professional installation, I only have high praise. I love my Lennox system and I love Environmental Heating and Air Solutions.
Fred Stevenson
Zac is knowledgeable
Zac has been to our home twice in 2 years for repairs. Our air and heating unit in our home were purchased in 2019. We have been diligent about having the system checked each year, and just this year we will have it thoroughly cleaned!
Zac is knowledgeable and gives us pricing for each job. I look forward to working with Zac! Thanks, Zac!
Sylvia Lopez

Trevor Rackley
Wonderful from start to finish
Environmental Heating and Air were wonderful from start to finish. Eddie Saucedo, the lead on the install of my electric HVAC system, was professional, courteous, and knowledgeable. He paid attention and responded to all my questions. The work was done as scheduled, completed on time, and the crew cleaned up well. The rest of the team, from the service tech, sales rep, and reception staff, are also great and very responsive.
Jody
Very knowledgeable technician
Our heater stopped working, and they sent a technician who was very knowledgeable and did a temporary fix and gave us our options.
maher Umari
Great company I’ll keep using
So glad I have regular checkups on my system, which is about 20 years old. Two of the ducts had completely lost the insulation due to age and weathering effects. Harjotan Singh did an excellent job replacing both. He showed me each duct being replaced so I could see for myself how much it needed it. If EHAS hadn’t been checking my attic ducts, I wouldn’t have known anything was wrong until they burst and suddenly no AC/heat. Yikes! Great company who I’ve done business with for many years and will keep doing so.
Peggy Mabes
Best heating and air company
Best heating and air company, outstanding customer service. They installed my system and maintain it. The tech that comes here, Shannon, is always awesome. Very, very nice fellow. I'm always happy with EHA.
John M
Really excellent service from Kevin
Really excellent service from Kevin. Arrives when he said. Got the job done. Helped me register on Lennox app. Patiently answers all questions. A real 5-star guy.
Sally Rhodes
From First to Last, 5 Star
From first to last Environmental and Air Solutions was 5 star. The representative, Kevin Coulter, was very good in explaining the difference in all the options. I especially appreciated that he did not try to convince me to buy the most expensive but recommended a system based on my needs. The install technicians were efficient and left the area spotless. The city inspector had questions about the amps. The technicians came back and left notes and a splice to show what was installed. I highly recommend the company.
Barbara Cross
Very Professional
Harjotan was very professional and even gave our doggies some love! Thanks, Harjotan.

KJ Is the Consummate Professional
My experience with Environmental Heating and Air Solutions was tremendous. From the beginning to the completion of the installation, Chris (Sales Representative) was great. He was informative, low pressure, honest, and knowledgeable. The installation team was excellent. Eddie and Marcus are extremely professional, courteous, respectful, and talented HVAC technicians. I highly recommend Environmental Heating and Air Solutions. They installed a Lennox HVAC system in our home. Thank you all for a job well done!
FOLLOW UP
I have experienced issues with my new Lennox HVAC system. I have been working with “KJ” for resolution of the issue. KJ is the consummate professional. He is detailed, knowledgeable, resourceful, and 100% customer centric. He is easy to communicate with and is committed to making sure that my Lennox system is working correctly. I am disappointed that the Lennox HVAC system has not worked consistently, however, KJ and the support team have conducted themselves with respect and kindness. I am extremely THANKFUL to have such a genuine technician in my corner. I appreciate all you have done, KJ.
FOLLOW UP 9-9-2025
KJ is the consummate professional. I requested a service call because I am continuing to have issues with my recently installed Lennox HVAC unit (specifically the A/C). I had no idea that he would be the technician that was going to respond to my latest service call. I was relieved to see him at the door because I have confidence in his abilities. KJ is diligent about his duties, and he has earned my trust. I am less confident about the Lennox system installed because of the multiple problems that I have experienced. I will continue to work with Environmental Heating & Air to resolve my A/C concerns in hopes that a resolution is established so that I can move towards a semi-annual maintenance type of relationship. I can't thank KJ enough for his support.

Jordan A Hamilton PhD
Very happy with the job Eddie and Marcus did
I am very happy for the job Eddie and Marcus did. Eddie is very professional in details and expertise in installation of the heating and air condition system. He explained all the details. First of all, I called Environmental heating and air condition to make an appointment. Next day I met Jen; she explained everything to me and arranged the system to be installed in 3 days! She was very helpful. Thank you for the great service.
