Get answers to common questions about hvac services in Merrimack, New Hampshire.
For furnaces, schedule replacement in late summer or early fall before the busy winter season. For air conditioners, aim for early spring before the summer heat and humidity arrive. Scheduling during these shoulder seasons in New Hampshire ensures better availability, potential off-season discounts, and avoids the emergency premium pricing during a January cold snap or a July heatwave.
For a full system replacement (furnace and AC), Merrimack homeowners can expect a range of $8,000 to $15,000+, depending on system size, efficiency (SEER/HSPF), and home complexity. Local factors like the need for chimney liner updates for high-efficiency furnaces or dealing with older home layouts can affect cost. Always get multiple itemized quotes from licensed local providers.
Yes. Merrimack residents should first check for rebates directly from their utility provider, such as Liberty Utilities or Unitil, which often offer incentives for high-efficiency heat pumps and furnaces. Additionally, New Hampshire’s NHSaves program, funded by ratepayers, provides rebates for qualifying ENERGY STAR® heat pumps and other equipment, helping offset the upfront cost.
Always verify the contractor holds a valid New Hampshire Master HVAC License (#3000s) and proper liability insurance. Choose a company with deep local experience, as they understand Merrimack's specific needs—like designing systems for our cold winters and humid summers, and navigating older homes common in the area. Check for strong reviews on local community pages and ask for references.
Yes, this is a common concern. Standard air-source heat pumps lose efficiency as outdoor temperatures drop below freezing, which is typical for Merrimack winters. This is why many local systems are installed as "dual-fuel" hybrids, pairing a heat pump with a gas or propane furnace. The furnace provides efficient, powerful heat during the coldest stretches, ensuring comfort and cost-effectiveness throughout the entire New Hampshire winter.
