Frequently Asked Questions — HVAC in Merrimack
Why is my AC not cooling my Merrimack home properly?
The most common causes of poor AC performance in Merrimack homes include low refrigerant, dirty evaporator or condenser coils, a failing compressor, clogged air filters, or leaky ductwork losing conditioned air before it reaches living spaces. Given harsh winters with heavy snowfall and hot, humid summers, a weak AC can quickly become dangerous. Call us for a same-day diagnostic — (888) 392-7512.
What's the best HVAC system for Merrimack's climate?
The best HVAC system for Merrimack depends on your specific home and budget. Given harsh winters with heavy snowfall and hot, humid summers, we typically recommend high-efficiency systems with SEER ratings of 16+ for cooling and AFUE ratings of 96%+ for heating. Heat pumps are increasingly popular in NH as they handle both heating and cooling efficiently. Our technicians will match the right system to your home's needs.
How can I tell if my HVAC ducts are leaking in Merrimack?
Signs of leaky ductwork in Merrimack homes include uneven temperatures between rooms, higher-than-expected energy bills, excessive dust near vents, and a system that runs constantly without maintaining the set temperature. Leaky ducts can waste 25–30% of your conditioned air. Our Merrimack team offers professional duct sealing that typically pays back in energy savings within 1–2 heating or cooling seasons.
