Had an issue with the old A/C not working texted Shane and he was by the next day. He seems to be available by phone, text email and whatsapp all the time and answers all questions. If I (customer) don't want something he will not push it on you. He is very hardworking, honest and knows what he is doing, and if somethings not right he will make sure it's right and explain the reasoning. Unit was 25 yrs old and had to be replaced due to old low refrigerant not widely available or used anymore and could have a leak. So the A/C unit + condenser and motherboard for it to communicate to the old furnace. I mentioned about different brands that I liked and disliked and no pressure on choosing which one. We worked out a deal and the install was completed successfully. I highly recommend Shane for any HVAC gas, A/C, or heating work.

We called Shane recently when we discovered our hot water tank was leaking from the base. He came immediately, diagnosed the problem and offered us solutions. With his help we decided on a Rinnai tankless heater and 2 days later he installed it!! His work was excellent, his prices very fair, he's great to deal with, and best of all he came by a couple of days later to check that everything was working fine and we were happy with his job. So yes, we'll happily recommend him to anyone needing their HVAC serviced/repaired! Thank you, Shane!!!

Shane from First Choice replaced our 40 year old furnace which had died. Since this was a no heat situation he changed his schedule so that he could service our home. He is very knowledgeable helped us in the decision-making process on what size of furnace to get. He didn't try to oversell us rather educated us on what was required. I had a great experience with him I would highly recommend Shane for any of your HVAC needs.
