"Steve and his team are very professional and get the job done in a timely fashion. We had three quotes on a new HVAC system and his was by far the lowest. They were wonderful to deal with and would hire them again without question."

"Kyle came to inspect my condo's HVAC. He was punctual, friendly and professional. I'm a new homeowner and he patiently answered all my questions about this stuff! I couldn't get access to the ac on my roof, so he didn't get to look at that but he spent a lot of time making sure my furnace was cleaned and in good order and looked at the air vents. He found a small gas leak on the furnace and sealed it up for me, thankfully. I will definitely contact them again for anything HVAC related!"

"Rob was fantastic. Very knowledgeable. Very kind. He took me step by step through. the whole process of replacement. I appreciated how he made sure I understood everything. In the end a family member helped with a quick fix. For now OK. But for anyone looking for someone to trust and give you honest information. EE'S HVAC is one you should call."
