Frequently Asked Questions About Commercial HVAC

How is commercial HVAC different from residential HVAC?

Commercial HVAC systems are designed to handle the larger and more complex demands of business environments. They typically cover greater square footage, serve more occupants, and must maintain consistent comfort across multiple zones or floors. Commercial equipment — including rooftop units, packaged systems, chillers, and variable air volume systems — is built to run for extended hours under heavier loads than residential equipment. Installation, maintenance, and repair of commercial systems also require specific training and licensing. Holt’s technicians have the commercial HVAC experience to work on the types of equipment found in Iowa offices, retail spaces, warehouses, and light industrial facilities.

How often should a commercial HVAC system be serviced?

For most commercial properties, Holt recommends scheduling professional HVAC maintenance at least twice a year — once in the spring before the cooling season and once in the fall before winter heating demands increase. High-traffic facilities, buildings with specialized equipment, or businesses in industries with strict indoor air quality requirements may benefit from more frequent service. Regular maintenance reduces the risk of unexpected breakdowns, keeps energy costs in check, and helps extend the useful life of expensive commercial equipment. A planned service schedule is far less disruptive — and far less costly — than an emergency repair during peak business hours.

What are the signs that a commercial HVAC system needs repair?

Commercial HVAC problems rarely resolve themselves — and what starts as a minor issue can quickly affect employee productivity, customer comfort, and operating costs. Watch for these warning signs:

Inconsistent temperatures across different areas of the building
Unusual noises coming from rooftop units, air handlers, or ductwork
A noticeable increase in energy costs without a change in usage
Poor indoor air quality, excess humidity, or persistent odors
A system that cycles on and off frequently or struggles to maintain set temperatures

If your team or your customers are noticing comfort issues, it’s worth having Holt take a look. Early diagnosis almost always means a faster, less expensive fix.

Can Holt Plumbing & Heating handle HVAC service for my business without disrupting operations?

Absolutely — and it’s something we take seriously. Holt understands that downtime has real costs for businesses, and we work with commercial clients to schedule maintenance and repairs at times that minimize disruption. For routine maintenance, we can often work around your business hours. For urgent repairs, we move quickly to restore comfort and functionality as fast as possible.

We treat your commercial property with the same care and respect we’d bring to any home in Des Moines.

"I highly recommend Holt! I needed my water heater replaced, and they came out and took the time to discuss all of my options and to make sure that I fully understood everything about the project. They did quality work, with all of the plumbing in traditional copper. That was important to me because I didn't want any of that PEX in my home! My entire basement looks cleaner and tidier because of the work they did! I was also very impressed that they didn't talk down to me as a woman. I like to do my own appliance maintenance and repairs when possible, and they respected my desire to understand everything about the installation and the prospective maintenance into the future."

"Holt heating and air conditioning installed our heating and air conditioning system and now we have the maintenance program with them. All the different people we'd have had out to do the semi annual maintenance have been courteous and professional in there attire and speaking to us. I would use them for other services in a heartbeat."

"Looking for a no fluff, no BS review of Holt? I got you... Over the past 15 years I've been a home owner, We've tried more companies that I could count. Lots of shady businesses out there... We were coming of a brand new HVAC installation just two years ago and the previous company completely botched it. It had problems within a month of installation and they were completely MIA. We ran it as long as we could to try and recoup the some cost, but it was a constant worry. Decided to give Holt a chance and we're so glad we did! Yes, they were more expensive, but it's the classic "you get what you pay for". 100% worth it! It's so hard to find a company that has the perfect mix of quality, punctuality, and honesty and Holt nails it. I genuinely appreciate their level of service and will pay a bit more to have someone I have the utmost confidence in doing the right thing. You should definitely give them a look if you need heating, cooling, or plumbing work."
