Vickie M.
★★★★★
They were very professional and explained things to me about my filter replacement in a couple months that I had not been told before and it was very useful information. I appreciated the time they took with me.
Debra D.
★★★★★
Lynden Sheet Metal just did the annual inspection of a heat pump/furnace they installed last year. As always polite, amiable & knowledgeable service people completed the inspection. All is well. Great service.

Kevin went the extra mile, not only showing me how to work the remotes properly but also checking each Daikin split for cleanliness. Now I know how and how often to clean the mesh vents.

Signs Your Home Has Poor Indoor Air Quality

Poor indoor air quality often shows up in a few recognizable ways. Here’s what to watch for.

If any of these sound familiar, it’s worth having your home’s air quality evaluated to identify the underlying cause.

Our Indoor Air Quality Solutions

We offer a range of solutions depending on what your home actually needs. Air purifiers help remove particles, allergens, and pollutants from circulating air, while humidity control systems address moisture levels that can lead to mold growth or that persistent musty smell. Ventilation improvements can also make a big difference, particularly in homes where stale air tends to linger.

Bellingham and Lynden’s damp Pacific Northwest climate makes humidity control especially relevant for many homeowners in our area. We evaluate your home’s specific conditions before recommending equipment, since the right solution depends on factors like your home’s size, existing HVAC system, and the particular issues you’re experiencing.

How Poor Air Quality Can Affect Your Home and Health

Poor indoor air quality can contribute to a range of health issues, particularly for those with allergies, asthma, or respiratory sensitivities. Excess humidity and mold growth can also aggravate these conditions, and prolonged exposure can affect anyone in the household over time, not just those with existing sensitivities.

Beyond health, poor air quality can take a toll on your home itself. Excess moisture can damage building materials, encourage mold growth in hidden areas, and even affect the performance of your HVAC system as it works harder in less-than-ideal conditions. In Bellingham and Lynden’s damp climate, addressing humidity is often just as important for protecting your home as it is for protecting your health.

Why Homeowners Trust LSM Heating, Plumbing, Electric for Indoor Air Quality

Bellingham and Lynden families have relied on us for their heating, cooling, electrical, and plumbing needs for generations, and indoor air quality is no exception.

We’d rather recommend what your home actually needs than sell you more equipment than necessary.
