EDIT: Earnest reached out to me and came out next day to resolve the issues I had. He and his technician were here early, listened to my complaints and made sure to fix everything. Job looks 10X better. Really do appreciate them coming back out and fixing things.-----------------------------------First technician who came out was great. The guy who actually did the install, not so much. I needed a new drain line installed for my attic unit. 2nd technician shows up nearly an hour after the window he said he would be, was only able to do about half of the job because he forgot a ladder. Installed the tube, but didn't seal the hole where it came out of the house. The tube itself droops in spots so it doesn't just drain, it'll pool until it hits its mass and then pour out. The tube also doesn't run to the ground and just ends about 5 ft off the ground.The technician also left all his trash and unused/ dropped extra materials all over the backyard.The overall cost for this was nearly $1100 for about $100 of materials and a bad home DIY job.

Was connected with ELM through my home warranty company. They came out the next day, promptly called to tell me when/who would be out and reached out after with the diagnosis. They waited patiently while I priced out my options and then scheduled me next day after I reached out to confirm the service. They had the best price, the fastest turn around time, and a very professional staff. Ernest was a delight to work with and the whole experience was so easy.

We had a fantastic experience with ELM. Earnest was our HVAC technician. From the moment we put in our service request, he was incredibly responsive, reaching out almost immediately to get us scheduled. He arrived right on time, was polite, professional, and made the entire process smooth and stress-free. It's rare to find someone who genuinely cares about their work and customers, but Earnest exceeded all expectations. Highly recommend him and ELM for anyone in need of reliable HVAC service!

Ernest and his team provided excellent service from start to finish. If you’re looking for someone who is honest and provides great prices give ELM HVAC a call. Very knowledgeable and explained all of our options on replacing our old system. Will use them for all future HVAC needs

I requested a HVAC call and they were at our home the following morning. Mr Ernest Harris listens to our concerns patiently. He made the diagnosis quickly and repaired the issue the same day. We had excellent service and an outstanding client experience!
