Dowling Corporation - Portsmouth's Professional HVAC Repair

High heating bills in our coastal New England climate are often due to an aging or inefficient HVAC system, poor insulation, or ductwork leaks. Our technicians perform comprehensive energy audits to pinpoint the exact cause, whether it's a furnace needing service, a heat pump losing efficiency, or recommendations for system upgrades. We provide clear, honest assessments to help you improve comfort and reduce your energy costs.

Our custom Preventive Maintenance Plans are tailored to your specific system and needs. A typical visit includes cleaning critical components, checking refrigerant levels, inspecting electrical connections, testing safety controls, and calibrating your thermostat. This proactive care helps prevent unexpected breakdowns, extends the life of your equipment, and maintains its efficiency, which is especially important for handling our local seasonal extremes.

We understand that a loss of heat or cooling is urgent. For our local customers in Portsmouth and nearby towns, we prioritize emergency service calls. Our dispatch team works to get a certified technician to you as promptly as possible, often the same day, to diagnose and resolve the issue, restoring comfort to your home quickly and reliably.
