This historic town, with its blend of colonial charm and modern development, presents unique heating and cooling challenges that we’ve mastered over years of dedicated service.

Our team recognizes that Exeter’s variable New England climate demands reliable, efficient heating and cooling systems.

The diverse property types in Exeter require versatile HVAC solutions. Historic homes near Phillips Exeter Academy often need creative approaches to preserve architectural integrity while improving comfort and efficiency.

Emergency HVAC Response Throughout Exeter

Understanding that HVAC failures don’t follow business hours, we offer round-the-clock emergency service to Exeter residents and businesses. When your heating system fails during a January cold snap or your air conditioning gives out during a humid August afternoon, our friendly staff are always at your disposal. We recognize that proper air control and refrigeration is of maximum importance, particularly for businesses that depend on climate control for operations or inventory protection.

Our emergency response team maintains a comprehensive inventory of parts and equipment, allowing us to address most issues on the first visit. This preparedness is especially crucial for Exeter’s restaurants, medical facilities, and retail establishments where temperature control directly impacts business operations. We take pride in the fact that our customers have come to know and depend on our quality service, responding quickly.

Energy Efficiency Solutions for Exeter Properties

Energy costs continue to rise, making efficient HVAC systems more important than ever for Exeter property owners. We help customers reduce their energy consumption through several approaches:

• High-efficiency equipment upgrades that can reduce heating and cooling costs by up to 30%
• Proper system sizing to ensure equipment operates at peak efficiency
• Regular maintenance programs that keep systems running optimally year-round
• Smart thermostat installation for precise temperature control and scheduling
• Ductwork inspection and sealing to eliminate energy waste

Many Exeter homes, particularly older properties, benefit significantly from modern high-efficiency systems. We frequently work with homeowners to upgrade from outdated oil heating systems to efficient heat pumps or high-efficiency gas furnaces, often resulting in substantial cost savings and improved comfort.

When we founded our business, we established it with one basic belief that has managed to last throughout all these years: treating customers as if they were family. This philosophy guides every interaction, from initial consultations to emergency service calls. Along with this belief, the commitment to delivering high-quality service at a fair cost is always doable, and is an aspect of the Coastal Mechanical LLC standard of quality that we are not willing to compromise.
