Frequently Asked Questions About HVAC in Lebanon

Get answers to common questions about hvac services in Lebanon, New Hampshire.

1What is the typical cost range for replacing a central air conditioning system in a Lebanon, NH home?

For a standard single-family home in Lebanon, a full AC system replacement typically ranges from $5,000 to $12,000. This wide range depends on the home's size, the system's efficiency (SEER rating), and the complexity of the installation, such as ductwork modifications. Given our humid summers and the demand for efficient cooling, investing in a higher SEER unit (16+) can offer better long-term savings despite a higher upfront cost.

2When is the best time of year to schedule furnace maintenance or replacement in the Upper Valley?

The ideal time is during the late spring or early fall (April-May or September-October). Scheduling during these shoulder seasons ensures you avoid the extreme cold of a New Hampshire winter, when HVAC companies are busiest with emergency no-heat calls, and the peak summer demand for AC service. This timing allows for more appointment availability and ensures your system is fully serviced before you need it most.

3Are there any local rebates or incentives for upgrading to a more efficient heating system in Lebanon?

Yes, Lebanon homeowners should first check with New Hampshire's NHSaves program, which often offers rebates for qualifying high-efficiency heat pumps, furnaces, and boilers. Additionally, it's wise to inquire with Liberty Utilities or your specific electricity and gas providers for any local incentive programs. These can significantly offset the cost of upgrading to a system better suited for our cold winters.

4What should I look for when choosing an HVAC contractor in the Lebanon area?

Prioritize contractors who are fully licensed, insured, and have extensive local experience with Lebanon's climate and older home stock. Look for positive reviews on local community forums and ensure they perform a detailed load calculation (Manual J) for new installations, which is critical for proper sizing given our temperature extremes. A reputable provider will also clearly explain permitting requirements, which are common for major system changes in New Hampshire.

5My heat pump seems inefficient during the coldest weeks. Should I consider a different system?

Not necessarily. Modern cold-climate air-source heat pumps are designed to operate efficiently in temperatures well below freezing, which is essential for Lebanon winters. However, many local homes successfully use a dual-fuel or hybrid system, which pairs a heat pump with a gas or propane furnace. This setup uses the heat pump for moderate cold and automatically switches to the furnace during extreme cold snaps (often below 5°F), optimizing efficiency and comfort while managing operating costs.
