“My only regret is that I didn’t have my geothermal installed years earlier.”
The technicians are not only pleasant but they are extremely knowledgeable. Atel Air stands by their product and are always easy to contact even when you have a problem.

“We can now fill up our oversized bathtub without running out of hot water!!”
We had Atel Air install a new On-Demand hot water system. They did an amazing job, rerouting ductwork and pipes, leaving the furnace room neater and tidier than ever.

Frequently asked Questions

How soon can my boiler be repaired?

If you’re enrolled in our maintenance plan, you can expect same-day service, often within just a few hours. Non-members are scheduled at the earliest available time, which could be the same day or within a few days.

How do I know if a boiler is right for my home?

Boilers are an efficient and comfortable heating choice, especially with radiators or in-floor heating, as they distribute heat more gently than forced-air systems. Our experts can assess your home and recommend the best solution for your needs.

What are the benefits of converting from an oil boiler to a gas boiler?

Switching from oil to gas can save up to 50% on energy costs and free up valuable space in your basement. Our team has the expertise to safely and expertly handle oil-to-gas conversions.

Can boilers be used with snow-melt systems?

Yes—boilers efficiently power both in-floor heating and snow-melt systems, distributing warmth evenly from the ground up to keep indoor spaces cozy and outdoor areas like driveways, walkways, and patios snow-free all winter.
