The presence of many older homes leads to needs for system replacements, ductwork modernization, and energy efficiency upgrades to handle the significant temperature swings.

Frequently Asked Questions About HVAC in Loudon

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

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

For a full system replacement in Loudon, including a new outdoor condenser and indoor coil, homeowners can expect to pay between $6,500 and $12,000. This range accounts for the specific challenges of older New England homes, such as accessing equipment and updating electrical service, as well as the higher-efficiency units recommended for our humid summers. Always get multiple itemized quotes from local, licensed contractors to ensure a fair price for your specific home's needs.

2When is the best time of year to schedule a furnace replacement or major heating service in Loudon?

The absolute best time is during the late spring or early fall (April-June or September-October). Scheduling during these "shoulder seasons" ensures you avoid the extreme cold of a New Hampshire winter, when HVAC companies are swamped with emergency no-heat calls, and you can secure better pricing and more flexible appointment times. This proactive timing is crucial for preparing your system for Loudon's harsh, sub-zero winter temperatures.

3Are there any local rebates or incentives for upgrading to a high-efficiency HVAC system in New Hampshire?

Yes, New Hampshire homeowners should first check for rebates directly from their utility provider, such as Unitil or Eversource, which often offer incentives for high-efficiency heat pumps, furnaces, and boilers. Additionally, the federal tax credits for energy-efficient home improvements can apply. For systems like cold-climate air-source heat pumps, these incentives are particularly valuable in Loudon, as they are an excellent technology for both our hot summers and cold winters.

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

Prioritize contractors who are locally owned, fully licensed by the State of New Hampshire (Plumbing & Mechanical License), and insured. Look for companies with extensive experience servicing the specific types of systems common in our region, like oil boilers, propane furnaces, and heat pumps. Strong local references and membership in organizations like the Granite State Association of Plumbing-Heating-Cooling Contractors (GSAPHCC) are excellent indicators of reliability and community trust.

5My heat pump seems to struggle on the coldest Loudon winter days. Is this normal, and what can I do?

This is a common concern. While modern cold-climate heat pumps are designed for New Hampshire winters, during sustained periods below 20°F, their efficiency can drop, and a backup heat source (like electric resistance strips or a dual-fuel system with a furnace) will activate. To ensure optimal performance, schedule a pre-winter tune-up with a local technician to check refrigerant levels, defrost cycles, and backup systems, which is essential for our climate.
