About Warren Heating and Cooling, LLC
Warren Heating and Cooling, LLC is a Milford-based HVAC contractor holding a 4.6-star rating across 191 customer reviews. The company serves residential clients across five New Jersey counties, including Hunterdon County, Warren County, Somerset County, Morris County, and Middlesex County. This family-owned operation maintains standard weekday hours from 8 AM to 5 PM and provides financing options through NEIF to help homeowners manage equipment costs.
What distinguishes Warren Heating and Cooling from regional competitors is their comprehensive equipment lineup and follow-through on installation support. As a dealer offering high-efficiency heating systems, boilers, furnaces, and heat pumps, the company handles complex replacements including oil-to-gas conversions and radiant heating installations. Their indoor air quality services include iWave air purification, UV air purifiers, and ventilation systems. Critically, customers report that the team addresses post-installation issues at no charge, as demonstrated by documented cases where technicians returned multiple times to fine-tune new systems.
Reviewers repeatedly mention specific technicians who managed challenging situations. For one homeowner facing single-digit temperatures, technicians Mike and Brett arrived on a Saturday morning to complete an urgent furnace installation. Another customer experienced 33-1 Limit warnings after a full system replacement, and Warren sent technicians back repeatedly over several months to resolve airflow issues at no additional cost. Sales representative Melinda guided homeowners through financing options, while Paul provided detailed explanations of repair versus replacement decisions.
What Customers Say
Every one of the four fully visible reviews awards 5 stars, with customers consistently praising the company's follow-through on post-installation issues, competitive pricing, and responsive communication. Reviewers call out specific team members by name and highlight the team's willingness to return multiple times to resolve problems.
