Get answers to common questions about hvac services in Andover, New Hampshire.
The ideal time is during the shoulder seasons of late spring or early fall. Scheduling service in May/June or September/October avoids the extreme demand of our cold New Hampshire winters, ensuring better availability from local HVAC contractors and often more competitive pricing. This timing also provides a crucial buffer to ensure your new system is installed and tested before the first hard freeze.
Yes, homeowners should always check for incentives. Primarily, you should look into New Hampshire’s NHSaves program, which offers rebates for qualifying high-efficiency heat pumps, furnaces, and boilers. Additionally, consult with your local Andover HVAC provider, as they are best informed about current state and any potential utility-specific rebates from providers like Liberty Utilities or the New Hampshire Electric Co-op that can significantly offset installation costs.
Andover's cold winters with temperatures often dropping below freezing make heating reliability paramount. A high-efficiency cold-climate heat pump paired with a backup furnace (a dual-fuel system) is an increasingly popular and efficient choice for our region. For homes using oil, upgrading to a high-efficiency modulating boiler can provide substantial fuel savings. Proper system sizing for our specific heating degree days is critical to avoid inefficiency and discomfort.
Prioritize contractors who are licensed by the State of New Hampshire (Plumbing & Heating License) and fully insured. Choose a company with a long-standing local reputation in the Sunapee/Lakes Region, as they understand the challenges of our climate and older home stock. Ensure they perform a detailed Manual J load calculation to correctly size your system, not just match your old unit's capacity, and provide clear, written estimates.
Yes, you should treat unusual noises (banging, screeching, rumbling) from your furnace or boiler as urgent, especially as winter approaches. These sounds can indicate imminent component failure, a cracked heat exchanger, or airflow issues. Given that temperatures in Andover can plummet quickly, a sudden breakdown in January could be dangerous. Contact a local HVAC professional promptly for diagnosis to avoid a more costly emergency repair during a cold snap.
