Frequently Asked Questions About HVAC in Exeter

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

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

For a standard, efficient central AC system replacement in Exeter, homeowners can expect to pay between $5,000 and $9,000. This range accounts for the size of your home (typically 1,800-2,500 sq ft in the area), the system's SEER rating, and the complexity of the installation, such as updating ductwork. Given our humid summers, investing in a properly sized, higher-efficiency unit (16+ SEER) can provide better dehumidification and long-term energy savings, despite a higher upfront cost.

2When is the best time to schedule HVAC maintenance or replacement in Exeter?

The optimal times are during the shoulder seasons—late spring (April-May) for AC servicing and early fall (September-October) for furnace tune-ups. Scheduling during these periods ensures your system is ready for Exeter's cold, snowy winters and warm, humid summers, and you'll avoid the high-demand rush periods where wait times are longer. For replacements, planning in the fall or spring often provides more installer availability and potential promotional pricing.

3Are there any local regulations or rebates in New Hampshire I should know about when upgrading my HVAC system?

While Exeter follows the New Hampshire state building codes, there are no unique local town ordinances for standard HVAC replacements. However, it's crucial to hire a licensed New Hampshire fuel gas and refrigeration technician. For rebates, always check with Eversource or Unitil for incentives on high-efficiency heat pumps, furnaces, or air conditioners, as these programs change annually and can provide significant savings on qualifying equipment.

4How do I choose a reliable HVAC contractor in the Exeter area?

Look for a contractor with a solid local reputation, proper NH state licenses (Mechanical/Refrigeration and Fuel Gas Fitter), and proof of liability insurance. Ask for references from homes of similar age in Exeter, as many historic and older homes present unique installation challenges. A trustworthy provider will perform a Manual J load calculation specific to your home's construction and our climate, not just recommend the same size as your old unit.

5With our cold winters, should I consider a heat pump for my Exeter home, or stick with a traditional furnace?

Modern cold-climate air-source heat pumps are an excellent and efficient primary heating solution for many Exeter homes, effectively operating in temperatures well below freezing. However, for sustained periods of extreme cold common in New Hampshire winters, a hybrid system pairing a heat pump with a traditional gas or propane furnace as a backup ("dual-fuel") is often the most cost-effective and reliable year-round comfort solution. A local expert can assess your home's insulation and current fuel sources to recommend the best option.
