The outline is traced from the shape you drew on the map. It's approximate: the drawn line is about half a mile wide and was drawn by hand, so places within about 1.5 miles of it are marked "edge zone" and customers there are asked to confirm their address. The published outline is a smoothed version of your line (the dashed line is your original). Smoothing stays within about 0.3 mile of your line, doesn't enlarge the area, and changes no town's inside/outside or edge status. Your line ran just outside Northville's center, so the outline curves gently around it to keep Northville inside, as you confirmed. Rochester is marked not served.
To refine the outline, mark places Include or Exclude in the list, then copy the draft and send it back. Nothing here changes the public site.

It depends on the system and what's wrong. Call or book a visit to talk through your situation.
Yes, that's a core part of what we do. Call to check the soonest available time. If you smell gas, leave the building first and call your gas utility or 911 from outside.
Yes. We repair, replace and maintain water heaters along with furnaces and air conditioners.
A common approach is a furnace tune-up each fall and an AC tune-up each spring, with filter checks every one to three months. We can recommend a schedule for your equipment.
Your address, a short description of the problem and when it started, and, if you can see it, the brand and model on the equipment label. A phone photo of the label helps.
Home comfort guide
Explore indoor air quality, seasonal maintenance and how your equipment works.
Indoor air quality
Indoor air carries everyday particles like dust, pollen, pet dander and cooking smoke, along with extra moisture. Too much of it can leave rooms stuffy and uncomfortable, and it can bother people with allergies or asthma. The EPA describes three core strategies, with controlling sources usually the most effective. Managing moisture is extra practical advice that helps too.

Particles like these settle on surfaces and get stirred back up into the air. When they build up, rooms can feel stale and people sensitive to them may notice it more.
Most forced-air heating and cooling systems don't bring in outdoor air. They move the air that's already inside. Running the furnace fan circulates and filters indoor air, but it isn't the same as fresh-air ventilation.
The EPA calls source control usually the most effective way to improve indoor air: remove or reduce what causes the pollution instead of trying to clean it out afterward.
Ventilation brings in outdoor air and helps carry indoor pollutants out. It matters most during short bursts of activity, such as cooking, painting or showering.
The EPA describes air cleaning and filtration as a supplement to source control and ventilation, not a replacement. Filters capture particles from the air that passes through them. They generally don't remove gases, and they can't keep up with a strong source that's still running.
Ideal 30–50% Stay below 60%
The EPA advises keeping indoor humidity below 60%, ideally between 30% and 50%. Too much moisture can lead to moisture-related problems indoors. Michigan winters often run dry indoors, and summers often run humid.
Filters & maintenance
Look at it every month, especially in the heavy-use months of winter and summer. If it looks dirty, replace it.
Most standard disposable filters need replacing when dirty, and generally within one to three months. Follow the instructions from your equipment and filter makers.
These run on their own schedules, so follow their instructions. Pets, dust, renovation projects and heavy system use can all mean sooner changes.
Have your system checked yearly. We suggest the air conditioner before summer and the furnace before winter.
Tell us what you're noticing, like dust, dry air or stuffy rooms, and we'll talk through your heating and cooling system with you.

Southeast Michigan winters are long and summers are humid. Tune-ups in the shoulder seasons mean fewer surprises when you need the system most.
