Lammers Heating & Air Conditioning

The weirdest kind of fan club.

Here's a throwback to when Lammers Heating & Air Conditioning service technician Dave Sherfinski found this clogged and filthy humidifier while checking on a furnace for a customer of ours.

As you can see in the second photo, Dave not only replaced the humidifier pad but also cleaned the tray that holds it. That will help prevent potential condensate leaks, which can cause damage to a furnace.

This is just one example of the hidden problems our technicians catch during annual furnace inspections and tuneups. A little preventative maintenance now can help you avoid bigger headaches later. Want peace of mind heading into the heating season? Give Lammers Heating & Air Conditioning a call to schedule your furnace tuneup!

This is Mojo, a 4-year-old mixed breed dog with a resilient spirit and an even bigger heart. Mojo is also the Lammers Heating & Air Conditioning “Warm Your Home” Pet of the Month for October. That means Lammers will pay the adoption fee in full for anyone who adopts Mojo from the Cascades Humane Society during the month of October.

Mojo is ready to leave shelter life behind and find a loving family to call his own. He is currently undergoing treatment for heartworm disease, and his future family will need to continue following the treatment plan recommended by their veterinarian. He is also missing a few toes, but that doesn't stop him from enjoying life or getting around.

Mojo has been neutered and microchipped, and he is up to date on his vaccinations. To learn more about Mojo call the Cascades Humane Society at (517) 787-7387 or stop by and visit us at 1515 Carmen Drive from noon to 6 p.m. Tuesday through Saturday.

Everyone knows what a turducken is, right? (That’s the holiday dish made by stuffing a deboned chicken inside a deboned duck and stuffing the stuffed duck into a deboned turkey.) Some of our team members recently found the HVAC version of the same thing.

This home near Cascades Park featured a monster furnace that was installed in the 1960s or ’70s. Then, in the early 2000s a new furnace was installed into the 50- or 60-year old furnace cabinet. Our team removed the monstrosity and replaced it with a high-efficiency air conditioning and furnace system that will save them money on energy bills along with making their home more comfortable, cleaner and safer.

And if you're wondering if we considered stuffing the new furnace into the middle of the old furnaces, no, we did not.

If your furnace isn't on already this fall, well, it will be soon. (Unless you really like the cold!) That means now is a great time to check (and probably change) your furnace filter. It's also a great time to get an annual tuneup.

Call us at (517) 787-6984 to get on the schedule. And thanks to JTV for having Todd Desy on last week!

Is your home missing a great dog? Mojo, a 4-year-old mixed breed dog with a resilient spirit and an even bigger heart, might be the dog you're looking for.

Mojo is the Lammers Heating & Air Conditioning “Warm Your Home” Pet of the Month for October. That means Lammers will pay the adoption fee in full for anyone who adopts Mojo from the Cascades Humane Society during the month of October.

Mojo is currently undergoing treatment for heartworm disease, and his future family will need to continue following the treatment plan recommended by their veterinarian. He is also missing a few toes, but that doesn't stop him from enjoying life or getting around. Mojo is looking for adopters who will appreciate him for the wonderful dog he is and provide him with the love and care he deserves as he continues to thrive.

Mojo has been neutered and microchipped, and he is up to date on his vaccinations. To learn more about Mojo call the Cascades Humane Society at (517) 787-7387 or stop by and visit us at 1515 Carmen Drive from noon to 6 p.m. Tuesday through Saturday.

💰💰 A SECOND OPINION COULD SAVE YOU THOUSANDS 💰💰
Some heating and cooling companies take advantage of customers and convince them to purchase a new furnace when a simple repair would get the job done.

Lammers Heating & Air Conditioning will NEVER do this. We would be honored to be your heating and cooling company, but we will NEVER sell you new equipment when a simple repair will do.

If a heating and cooling company has told you that you need a new furnace, contact us for a second opinion. It could save you thousands.
