## The honest read

McCarthy Heating Oil says on its website that it operates out of Quaker Hill, serving south-eastern Connecticut, with complete heating system installations and air conditioning among its work, and its BBB profile describes heating oil and fuel delivery. The company says it has been in business for 65 years. It holds 4.5 stars from 13 Google ratings and an A+ grade from the BBB.

A customer since 1978 said the company replaced their oil tank in less than a day, took the old one out and left no mess behind. A recent customer said two Mitsubishi split-system AC units were installed and the workmen were meticulous both inside and outside the house. One recent customer who needed a new AC unit said Mike recommended a unit with both AC and heat, and that Jeff and Brandon did the install and helped troubleshoot a couple of days later when the customer did not know how to operate it. A recent reviewer said McCarthy has been servicing the Montville WPCA for years.

Connecticut lists its S1 heating and cooling contractor licence, HTG.0386429-S1, as active, held by McCarthy Heating Oil Service Inc.

**Strengths:**
- Oil tank replacement — a recent customer said it took less than a day
- A split-system AC install — a recent customer called the workmen meticulous
- Install follow-up — installers helped troubleshoot a couple of days later
