One call handles everything. Our tagline says it best: One Call Does It All.
Air Conditioning Repair & Installation
Our technicians are fully licensed and insured, and they cover the full range of air conditioning work, from seasonal tune-ups to complete system replacements. A maintenance visit typically includes refrigerant level inspection, coil cleaning, filter checks, and thermostat calibration. Catching issues before summer heat peaks can reduce the chance of a mid-season breakdown when you need cooling most. Same-day service is available for urgent calls.
Furnace Repair & Installation
New Hampshire winters bring extended stretches of below-freezing temperatures, and a furnace that fails mid-season isn't just uncomfortable. It needs a fast fix. Our team handles furnace repair and installation across all major brands and models, diagnosing everything from ignitor failure and heat exchanger issues to blower motor problems. Whether you need a same-day repair or a new unit installed, we can help keep your system working and your home warm through whatever the season brings.
Heater Maintenance & Replacement
A well-maintained heating system is the key to avoiding costly breakdowns and maintaining peak efficiency. Our technicians perform annual maintenance visits that cover burner inspection, heat exchanger checks, filter replacement, and flue inspection. This work can extend equipment lifespan and catch problems before they become emergencies. When a system is past its useful life, we handle replacement from selection through installation. Schedule heater maintenance before the cold sets in rather than waiting for an emergency call.
Heat Pump Repair & Installation
Heat pumps provide both heating and cooling from a single system. They're a practical fit for Hudson's mixed-climate seasons. We handle heat pump repair, installation, and maintenance to keep your system running efficiently year-round. Ductless mini split installation is also available for spaces where traditional ductwork isn't an option, giving you zone-by-zone temperature control without a full duct system. For customers considering a new heat pump or mini split installation, financing options are available. Ask about current terms when you schedule.
