I get my furnace inspected every year and Lynden Sheet Metal does a thorough job. I've been very happy with them for several years now. Abby was very knowledgeable and a delight to chat with. All of the technicians that they have are experienced and know what they're doing.

For 15 years LSM has been our go to. We’ve been fortunate that we haven’t had a lot of issues at our houses, but they’ve always been on time, courteous, very helpful and valuable. This time we did a pre-move inspection and cleaning to ensure our furnace was ready for our potential buyers.

I needed to have my furnace inspected. I was able to get an appointment in a very timely manner. The tech was very good and was able to troubleshoot the issue and make the repair. Top notch company!

Why Your Home Benefits From Regular HVAC Inspections

An inspection helps catch small issues before they turn into bigger, more expensive repairs. Components wear down gradually, and a trained eye can spot early warning signs that might not be obvious to a homeowner, like a slightly weakening part or a connection that’s starting to loosen.

Inspections also give you peace of mind, whether you’re buying a new home, preparing for a change in season, or just want to know your system is in good shape. In Bellingham and Lynden’s damp climate, regular inspections help catch moisture-related wear before it becomes a bigger problem for your system’s components.

What Our HVAC Inspection Covers

Our inspection process looks at the key components that affect your system’s performance and longevity. We check electrical connections, inspect coils and filters, and test your thermostat to confirm it’s communicating properly with your system. We also look for signs of wear, corrosion, or damage that could point to future problems.

Depending on your system type, we may check refrigerant levels, examine the blower motor, or inspect ductwork for leaks. By the end of the visit, you’ll have a clear picture of your system’s condition and know whether anything needs attention now or in the near future.

Signs It's Time for an Inspection

A few signs suggest it’s a good time to schedule an inspection. Here’s what to consider.

The Best Time to Schedule an Inspection

Scheduling an inspection before the demands of peak heating or cooling season gives your system time to be checked and adjusted before it’s working at full capacity. This is especially useful in Bellingham and Lynden, where damp weather can affect system performance throughout much of the year.

Homebuyers and sellers also benefit from scheduling an inspection during a real estate transaction, since it provides clarity on the system’s condition for both parties. Whatever your reason, an inspection is worth fitting into your schedule before you actually need answers about your system.

Why Homeowners Trust LSM Heating, Plumbing, Electric for HVAC Inspections

Bellingham and Lynden homeowners have relied on us for their heating, cooling, electrical, and plumbing needs for generations, and inspections are no exception.

We’d rather give you an honest picture of your system than talk you into work you don’t need.
