Common Furnace Issues in Mount Washington
In our neighborhood, I see a lot of furnaces that won't ignite. Usually, this is a simple fix like a failed hot surface ignitor or a dirty flame sensor. These parts are designed to wear out over time, and I keep them stocked on my truck so I can get your heat back on the same day.
Another pattern I see is 'short-cycling'—where the furnace kicks on, runs for a minute, and shuts back off. This is often a pressure switch issue or a sign that the system is overheating because of a dirty filter or blocked airflow. Because Mount Washington homes have such varied layouts, I always check your duct condition and airflow to make sure the fix will actually last.
Hillside Heating Challenges
Mount Washington’s steep hills and narrow streets aren't just a challenge for driving; they affect how we service your HVAC. Access is the first thing I look at. If your furnace is tucked into a tight attic or a crawlspace, I take the time to ensure the equipment is accessible for future maintenance.
Because our homes range from historic cabins to new construction, there is no 'one-size-fits-all' repair. I look at the electrical layout and duct condition to ensure that any repair I perform is safe and compatible with your home's specific setup.
My Diagnostic Process
Every service call starts with safety. I don't just look at the part that failed; I check the whole system. This includes a CO measurement and a heat exchanger inspection to ensure there are no safety hazards. I want to make sure your home is safe before I even talk about a repair.
Once I identify the fault—whether it's the gas valve, the control board, or a blower motor—I explain exactly what happened. You get a written estimate for the repair cost before I turn a single wrench. No surprises, just honest work.
Repair vs. Replacement
A lot of contractors will try to sell you a new furnace the moment something breaks. I take a different approach. If your furnace is 15 or 20 years old but the repair is minor, I’ll tell you it’s worth fixing. I’m here to help you get the most out of the equipment you already have.
However, if the repair cost is high or the heat exchanger is compromised, I’ll be honest about that too. I’ll explain why replacement might be the better long-term choice for your home, giving you the facts you need to make a decision that fits your budget.
Safety First
Your family's safety is the most important part of my job. I perform a combustion analysis on every furnace service call. If I find a cracked heat exchanger or a venting issue, I will show you exactly what I found. I won't leave a system running if it poses a safety risk, and I won't use safety as a scare tactic to sell you a new unit.
Mistakes to Avoid
The biggest mistake I see is ignoring small warning signs. A squealing blower motor or a faint smell of burning plastic usually means something is about to fail. If you catch these early, the repair is usually straightforward. If you wait until the system stops working entirely, you might end up with more damage to other components.
Another mistake is neglecting basic maintenance. A dirty filter can cause your furnace to overheat and shut down, which mimics a major mechanical failure. Always check your filters before calling for service.
Understanding Costs
I believe in flat-rate pricing. You shouldn't have to worry about how long a job takes. Whether it’s a flame sensor cleaning for $100–$175 or a gas valve replacement for $350–$600, you will know the price upfront. My diagnostic fee covers the time it takes to properly inspect your system and provide you with a professional assessment.
