Highlights
- Fast emergency response — 2025–26 reviewers described arrivals within an hour
- Heating replacements — late-2025 reviewers called boiler and furnace prices fair
Denis Plumbing & Heating got the call when something broke, and customers from October 2025 to February 2026 kept saying how fast it showed up. Google shows 5 stars from 20 ratings. In a January 2026 Google review, a homeowner said their furnace died before 8am on a weekend, on the coldest day of the year, and they had heat two hours later. Another that month had water coming out of a ceiling light fixture and said the crew arrived within an hour and had the problem found and fixed within another hour. In November 2025 reviews, customers described a boiler fixed on the spot and a water heater replaced after the crew arrived within an hour of the call. Several reviewers, in October and November 2025, had boilers, furnaces or water heaters replaced and said the price was fair. Customers name Deni and Roni as the people doing the work.

I needed a faucet replaced and they were in no time. Quick and thorough. Couldn't ask anything better. If I could give them 10 stars I would.
