"Furnace died on a Sunday night in January. EcoThermix had a tech at my door by 7am Monday. Fixed in two hours. These guys are absolutely the real deal."
"We installed a Mitsubishi heat pump through EcoThermix and received $11,000 in rebates. They handled every piece of paperwork. Couldn't believe how painless it was."
"The AC rental is the best home decision I've made. Zero upfront, all repairs included. When we had a refrigerant issue in July, they came same-day for free. Mind blown."
"Got 3 quotes before EcoThermix. Their price was fair and the technician actually explained what he was doing. Clean, respectful, and done way faster than expected."
"Water softener + RO system installed in half a day. The difference in water quality is night and day. Our skin is better, appliances last longer. Worth every penny."
"Called at 10pm when our heat went out. Marcus arrived at 7am and had it running by 9am. Having the Ultimate Protection Plan was 100% worth it — paid for itself in one call."
