If you’re a business owner, you know that functioning plumbing and HVAC systems are not optional– they’re essential for keeping your business up and running. A comfortable and well-functioning space keeps employees happy and increases productivity overall. It gives customers a great first impression and encourages them to take their time and come back again in the future. Regardless of what type of company you run, it’s critical that your plumbing, heating, and cooling systems are functioning effectively and serviced by a professional when necessary.

You can rely on the experts at A-1 Services, Inc. for sewer replacements, gas piping, and other plumbing replacement needs! Depending on the material and purpose of your pipes, you may need a replacement for your supply pipes, toilet pipes, drain lines, or even your water heater. If you notice anything close to low water pressure, repeated leaks, discolored water, or frequently clogging drains, it may be time for a complete pipe replacement instead of just a repair. Our skilled workers would be happy to help you identify the issues and set up a refreshed system.


The summer months– and fall, spring, and even winter– in southern Utah and Nevada can be swelteringly hot. A-1 Services, Inc. offers maintenance, repair, installation, and replacement of air conditioning systems. Commercial buildings can vary significantly depending on whether they’re used as an office, retail, dining, manufacturing, warehouse, or another kind of space. Certain air conditioning setups may be better suited for each of these spaces. The HVAC experts at A-1 Services, Inc. can help you understand and install the most efficient cooling system for your space. We also offer spring AC tune-ups to make sure your air conditioning system is maintained and ready to handle the summer season to come.
