# D. A. Dalelis Plumbing, Heating and Cooling

**Trade:** Plumbing · **Languages:** English, Spanish

**Rating: 3.2/5** (low confidence) — from 0 reviews across 2 sources.

## The honest read

D. A. Dalelis Plumbing, Heating and Cooling presents itself as a Massachusetts plumbing and heating company established in 2005. Angi lists commercial and residential installation and repair, emergency service, free estimates, and warranties.

The written customer history is extremely thin: one undated web mention says, "I had a great experience working with James and his team to install our new boiler and water heater". That is a favorable account of specific installation work, but its date and context are not shown.

Before booking, confirm the service area, the exact plumbing or heating scope, and the terms of any estimate and warranty. Ask whether the person quoting the job will also handle the installation and what emergency response covers.

The available material fits routine plumbing, heating installation, and repair inquiries, but it is not enough to judge consistency across projects. Get the proposed equipment, labor, warranty, and arrival window in writing.

**Strengths:**
- Installation experience — one mention praises boiler and water-heater work
- Service options — Angi lists emergency service, estimates, and warranties
