Tankless Hot Water Heater Replacement in Sudbury, MA 01776

“Just wanted to highly recommend Chaves HVAC. Before/after photos of my latest energy efficiency upgrade. (Navien OnDemand hot water). Chaves performed the work promptly and flawlessly. I'd gotten a quote in Jan, thinking about it, then weekend wind storm caused power surges that fried electronics atop the old tanks (also fried my refrigerator and garage door opener). Chaves fit me in within 24 hours of my call, and got it done without a hitch. Hot water again! (Mass Save rebate eligible too).”
