We are a full service HVAC company offering service and installation on furnaces, air conditioners, boilers, geothermal, and water heaters. We also perform premier duct cleaning services along with boiler water quality testing and treatment. Des Moines Comfort, Inc. has been the metro's leader in Geothermal and Radiant Floor Heating service and installation for over 13 years. We offer yearly service agreements and service the entire metro and surrounding areas.

"Last night, our furnace stopped working and we woke up to 56° indoor temp and dropping. To complicate matters, our household is currently sick with COVID and we were unable to have a technician enter our home because of this. After speaking with Jackie (the appointment secretary), I received a call back from the manager, George. George was very kind and explained why they couldn't send a technician out (completely understandable). He then continued to offer to walk me through things to check to identify and possibly solve the problem. I stayed on the phone with him while he walked me through trying a few different things, and by the end of the 25ish minute phone call I had a working furnace again. I am so beyond grateful for the above and beyond service George and his company supplied to me today. Because of him, we have a warm home to recover in. Thank you, George."

Gas Leak Repair questions, answered by experts

Earthquake gas shut-off valves, or seismic gas shut-off valves, are safety devices that attach to your natural gas line. When an earthquake hits, the valve automatically turns off the flow of gas. Earthquake gas shut-off valves can prevent gas leaks, which are especially dangerous after a quake due to the risk of fire and explosion.

Plumbers start by walking around the property to see if they notice any signs or sounds of a gas leak. They can also use tools like electronic gas detectors and infrared cameras to find the source of leaks. There are also detectors that use laser, thermal, and multi-wavelength imaging. All these devices allow a plumber to scan your home and pinpoint the exact location of a leak.

Local codes often mandate specific fittings, permits, and vent considerations for permitted function and safety, which are enforced by professionals.

Most qualified local plumbers in your area should be able to help with this job. However, it's always best to check with your utility company before starting any gas-related project. Speak with them about your needs and request recommendations for licensed plumbers who can pull permits and properly install the line.

Not all gas fireplaces need a chimney. If you install a ventless gas fireplace, it will release low levels of combustion byproducts back into your living space (instead of pushing them outside through a chimney or vent). Ventless fireplaces burn fuel efficiently, so the emissions are minimal—but they could bother people with allergies or respiratory issues.
