## The honest read

First Rate Mechanical LLC works on heating and air-conditioning equipment, and its site says it services oil and gas boilers and furnaces. Its New Hampshire HVAC licence, number MBE2501737, held by First Rate Mechanical, LLC, is active on the state registry. The company's stated service area includes Rochester, Dover, Portsmouth, Somersworth and Durham, and it carries a 5-star Google rating from nine ratings.

A 2025 customer said Andrew installed a new furnace, replaced old piping that was out of code, and had the new system up and running in two days. In a 2025 review, a customer wrote that Andrew tracked down obscure parts for a tricky A/C issue and got it fixed in time for a heat wave. A 2025 customer said having Andrew diagnose and repair a mini split system was quick and easy.

A 2025 reviewer described a preventative maintenance service of old A/C units at an office, with air filter replacements, and said Andrew looked over the boiler and made recommendations. A 2025 customer called the price fair on an instant hot water heater that went out unexpectedly, and said they then had the company put a propane heater into a shop. A 2025 customer said the rate saved them over $100.

**Strengths:**
- A furnace replacement — a 2025 customer said it ran within two days
- A tricky A/C repair — a 2025 customer said obscure parts were tracked down
- A reasonable rate — a 2025 customer said it saved them over $100
