Why Homeowners in Blaine, WA Trust Us

Our furnace went out on Christmas Eve. Called several places on the morning after Christmas and all went to voicemail with no call back. Someone told me about Lynden Sheet Metal and said they were wonderful. LSM answered the phone and squeezed me in on short notice so that we would have heat over the weekend. I can't say enough good about this company. The lady who took my call was friendly and helpful. The technician was the same and is highly skilled at his job. They have us back up and running for significantly cheaper than I expected. Lynden Sheet Metal is our go to provider moving forward!

Our furnace quit working and Lynden Sheet Metal quickly scheduled service. Their employee was very knowledgeable and professional, taking time to explain the problem and our options. He serviced our furnace and got it working in short time. I would definitely recommend them. The cost was also very reasonable.

I called them when my furnace stopped heating. They showed up on time (actually a little early, which was nice). The technician went right to work, and got the job done quickly. The price was affordable too. I would highly recommend, and I will definitely use Lynden Sheet Metal again if the need arises.

Signs Your Furnace Needs Repair

A Blaine home’s furnace usually gives a warning before it quits working altogether. These are the signs to watch for.

Cold air from vents
Strange banging or rattling
Frequent short cycling
Yellow or flickering pilot light
Rising heating bills
Uneven heat throughout the house

Calling at the first sign usually means a quicker, less expensive fix.

What's Really Behind Your Furnace Problems

The marine fog and dampness that settle over Blaine overnight bring persistent moisture that can work its way into a furnace’s components, especially in older waterfront cottages that were never sealed as tightly as newer construction. That dampness contributes to corrosion and wear over time.

Quick shifts between foggy, chilly mornings and milder afternoons also mean a furnace cycles more often than it would in a steadier climate, which adds wear to parts like igniters and switches.

Furnace Repair Done Right

Blaine’s older waterfront homes often have furnaces tucked into tight, retrofitted spaces that take some extra care to service properly. Our technicians are used to working in those conditions and know what to check first given the marine climate here.

Whether your home is an older cottage or a newer build set back from the water, we diagnose the specific issue and explain it clearly before any work begins.

Inside a Typical Service Visit

A homeowner named Susan along Blaine’s waterfront called after her furnace started shutting off unexpectedly on damp, foggy mornings. Our technician found a corroded sensor that had slowly worn down from years of persistent moisture in the air.

Replacing the sensor solved the shutoffs completely. Susan mentioned she’d assumed the whole system was failing, and was glad it turned out to be one specific part.
