Common Furnace Problems We Diagnose & Repair
Forced-air heating systems tend to fail in recognizable patterns, and our technicians have seen them all. Whether your furnace has stopped producing heat entirely or is just behaving strangely, a thorough diagnostic inspection is the first step before any work begins. You receive an upfront price before the technician touches anything, and our vans are stocked with commonly needed parts, so many repairs are completed in a single visit.
Here are the problems we most frequently diagnose and repair for local homes and businesses:
- No heat or weak output: Often traced to a faulty ignition system, failed pilot light, or restricted airflow from a clogged air filter
- Short cycling: Frequent on/off operation without completing a heating cycle, which can indicate a heat exchanger issue, an oversized system, or a thermostat malfunction
- Unusual noises: Banging, squealing, or scraping sounds that often point to blower motor or fan component wear
- Yellow or orange pilot light: A pilot flame that isn’t blue may indicate incomplete combustion, which can produce dangerous carbon monoxide. This is a safety concern that warrants a prompt professional inspection.
- Thermostat problems: Inaccurate readings or miscalibration that prevent the system from cycling correctly
- Blower motor failure: A non-functioning blower stops conditioned air from circulating through your ducts, leaving rooms unevenly heated
Furnaces older than 15 years, or systems that have needed multiple repair calls in a single season, are often better candidates for replacement than continued repair. Our technicians can walk you through the cost comparison after the inspection so you can make an informed decision. Every completed job, repair or replacement, is backed by a signed workmanship warranty.
Why Salem Homeowners Choose Cornerstone Services for Furnace Repair
There are plenty of HVAC contractors serving the Salem, NH area. What sets Cornerstone Services apart is the way we work, not just the services we offer.
- Per-Job Pricing: We price by the job, not the hour. The number we quote before the repair starts is the number you pay at completion, with no hourly overruns or hidden fees.
- Signed Workmanship Warranty: Every job is backed by a signed warranty under our quality assurance policy, giving you documented protection on our work.
- Background-Checked Technicians: Every worker we send to your home has passed a background check before setting foot on your property. They arrive in uniform, in a lettered vehicle, so you know who’s at your door.
- Tidy Job Sites: Our technicians clean up before they leave. We don’t leave your utility room or basement worse than we found it.
- Financing Available: For larger repairs or full system replacements, financing options are available. Ask about current terms when you schedule.
- Monthly Promotions: We run rotating special offers each month, so it’s worth asking what’s available when you call.
One more thing worth knowing: Cornerstone Services isn’t just an HVAC company. We handle electrical, plumbing, cleaning, and handyman services under the same roof, with the same pricing structure and the same warranty backing every trade. If your furnace call reveals a related electrical or plumbing issue, you don’t need to find and coordinate a second contractor. One call still does it all.
Frequently Asked Questions
How Do I Know If My Furnace Needs Repair or Full Replacement?
Furnaces that are 12 to 15 years old, require frequent repair calls, or have caused a noticeable spike in energy bills are often better candidates for replacement. AFUE efficiency ratings tend to drop as systems age. A technician inspection gives you the information you need to make that call with confidence.
How Often Should a Furnace Be Serviced?
Annual professional maintenance, ideally before the New Hampshire heating season begins in the fall, helps catch small problems before they become expensive ones. It also keeps the system running at its rated efficiency and can extend the useful life of the unit.
What Should I Do If My Furnace Stops Working Suddenly?
Check your thermostat settings and make sure the circuit breaker hasn’t tripped. If neither of those is the issue, it’s time to call a technician. Cornerstone Services offers around-the-clock availability for urgent furnace calls in Salem, NH, so you don’t have to wait until morning.
