Keep your building comfortable and running

Idaho is known for extreme heat and extreme cold, and that’s when commercial equipment breaks down. A clean, properly maintained system is less likely to fail when you need it most and costs less to run.

Repairs, replacements and Right Size maintenance

Our commercial technicians service all makes and models, from small rooftop units to air handlers large enough to park a semi in. We change motors, bearings and shafts, adjust economizer linkage, replace filters and handle complete equipment replacements.

With a Right Size maintenance plan, we assess your equipment and set a schedule that fits your business and budget, keeping operating costs down and breakdowns rare.

Rooftop units, air handlers and economizers

We repair, replace and maintain rooftop heating and cooling units and package heat pumps, and air handlers of every size. Yearly maintenance covers motors and bearings, blower wheels, belts, filters, door seals and amperage checks. Economizers bring in outdoor air for free cooling when it’s cool outside and fresh air year-round; we install, repair and set up their controls, from outdoor temperature to CO2 sensors and building automation.

Commercial boilers, unit heaters and waste oil heaters

We install, repair and maintain gas, propane, fuel oil and waste oil commercial boilers and hydronic heating systems, with yearly checks of glycol and inhibitor levels, gas pressures, combustion and the makeup water’s backflow preventer. Unit heaters, whether natural gas, propane, hot water or steam, heat shops, warehouses and pump houses efficiently. Waste oil heaters turn your fleet’s used oil into heat instead of paying to haul it away; we install them and service burners, pre-heaters and filters.

Server room cooling and heat recovery

Electronics generate heat, and a server room needs dependable cooling around the clock. Our certified technicians handle start-up, installation, repair and maintenance of Liebert and other precision cooling units, 24 hours a day, 365 days a year. For tight, well-sealed buildings, heat recovery units bring in fresh air while recovering heat from the air being exhausted.

    Josh and his crew (Oscar and Levi) came out to install my new water heater and repipe my entire home. It was 3 days and they did a fantastic job! I will add that my drywall guy came to make some repairs and he also said they did a fantastic job! Thank you again to the entire team!

    Smelled gas when we were unhooking the stove, called Drake they immediately sent Thomas out. Make sure you don’t lose him, he’s a keeper. He took care of the problem, we’re good to go.

    We had an excellent experience with Drake Mechanical. We needed a wine cellar AC split system repaired and they were able to help us out (apparently this requires a specialist). We appreciate their timely and professional repair.

    This is the second time Bryce has done repairs on my AC. He is so kind & knowledgeable and is thorough in explaining the issue and how it is being fixed. AC units are too expensive to replace & I appreciate that Bryce found other solutions.

Common questions

Have a question that isn’t here? Call us any time at (208) 362-6200.

How often should rooftop units be serviced?

At least once a year, and ideally before both the cooling and heating seasons. Idaho’s extreme heat and cold are when equipment breaks down, and a clean, properly running unit is less likely to fail then and costs less to run.

What is a waste oil heater?

A waste oil heater or furnace burns the used motor oil, gear oil and transmission fluid from your shop’s vehicles to heat the building, so you’re not paying to have that oil hauled away. We install new units and repair and maintain existing ones, including burners, pre-heaters and filters.

What does an economizer do?

When it’s cool outside, an economizer brings in outdoor air instead of running the cooling, which is essentially free cooling and lower utility bills. It also brings fresh air into the building. Economizers can be controlled by outdoor temperature, the building automation system or CO2 sensors.

Do you offer commercial maintenance plans?

Yes. Our Right Size approach builds a maintenance plan around your property, equipment and budget. We visit, assess your buildings and equipment, and set a schedule that fits how your business runs, so repairs and maintenance cause as little disruption as possible.

Do you offer 24/7 commercial service?

Yes. Emergencies don’t keep business hours, so a live person answers our phone 24 hours a day, 365 days a year, and we dispatch technicians for commercial and industrial emergencies day or night.

Fast. Friendly. Fixed.
