Frequently Asked Questions About HVAC in Hillsborough

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

1What is the best time of year to schedule HVAC maintenance or replacement in Hillsborough?

For maintenance, early fall (for heating) and late spring (for cooling) are ideal to ensure systems are ready for our cold winters and humid summers. For full system replacements, the "shoulder seasons" of spring and fall are best, as HVAC contractors in the Monadnock Region are less busy than during extreme temperature peaks. Scheduling during these windows often provides more flexibility and can prevent emergency breakdowns during a January cold snap or a July heatwave.

2Are there any local rebates or incentives for upgrading to a high-efficiency HVAC system in New Hampshire?

Yes, New Hampshire homeowners should first check with their local utility, such as Liberty Utilities or Eversource, for rebates on qualifying high-efficiency heat pumps, furnaces, or air conditioners. Additionally, the state of New Hampshire and federal tax credits for energy-efficient home improvements can significantly reduce the net cost. A reputable local HVAC provider will be knowledgeable about current programs and can help you navigate the paperwork.

3How does Hillsborough's climate affect the type of HVAC system I should choose?

Our climate demands a system capable of handling both extremes: humid, warm summers and long, very cold winters with temperatures often dropping below zero. This makes dual-fuel or cold-climate air-source heat pump systems paired with a backup furnace an excellent and efficient choice for year-round comfort. Proper sizing is also critical, as an oversized system will short-cycle in our milder seasons, reducing efficiency and comfort.

4What should I look for when choosing an HVAC contractor in the Hillsborough area? **Question:** What should I look for when choosing an HVAC contractor in the Hillsborough area?

Always verify that the contractor is licensed by the State of New Hampshire (Plumbing & Mechanical License) and carries proper insurance. Look for a company with extensive local experience, as they will understand the specific installation challenges of our older homes and rural properties. Check for strong reviews, clear written estimates, and membership in local business associations, which indicates a commitment to serving the community.

5My oil furnace is old. What are my most efficient and cost-effective heating options for a Hillsborough home?

Given the high cost of heating oil, many Hillsborough homeowners are switching to high-efficiency ductless or ducted cold-climate heat pumps, which provide both heating and cooling. For whole-home heating in very cold weather, a hybrid system (heat pump with a propane or high-efficiency oil furnace as backup) is often the most practical and efficient solution. A local HVAC professional can perform a detailed heat load calculation on your specific home to recommend the optimal system for long-term savings.
