Indoor Air Quality Solutions 

Few people realize the impact indoor air quality has on our health and well-being. The air in our homes is often less healthy than the air outside, which can lead to severe allergies, lowered immune response, and fatigue.

Luckily, United Air Temp has many solutions to combat indoor air pollution and fill your home with clean, fresh air. We can help you with:

  • Whole-home humidifier and dehumidifier installation
  • Attic fan installation and repair
  • Air scrubber and purifier installation
  • Dryer vent cleaning
  • R-22 conversion
  • Ductwork installation and replacement
  • Thermostat repair

Plumbing Services

At United Air Temp, we do everything possible to keep your fixtures and pipes operating as they should. Turn to our team for all your plumbing service needs:

24/7 Emergency Plumbing Repair

When your water heater bursts or your water pipe leaks, you can’t afford to wait for a repair. Our emergency plumbing services are available 24/7 to minimize damage and restore your home as soon as possible.

You need an emergency plumbing team if:

  • You have a frozen, leaking, or burst pipe.
  • You smell sulfur or rotten eggs, indicating a gas leak.
  • Your water heater has burst.
  • Your toilet is overflowing.
  • You have water stains on walls or ceilings.
  • Your basement is flooded.

Sewage Ejector Pump Replacement & Repair 

Your sewage ejector pump protects the integrity of your foundation and basement by removing sewage waste. You need a sewage ejector pump if:

  • Your property is built at a low elevation.
  • You need to move wastewater from basements and other rooms below ground level.
  • You experience frequent waste blockages.

We offer sewage ejector pump replacement and repair to ensure your equipment is always in optimal condition. While hydro jetting can remove tough clogs, it can’t prevent them from recurring. A sewage ejector pump is a practical long-term solution.

Gas Line Replacement & Repair

Your gas line has the potential to affect your entire family’s safety, so you need a trustworthy plumber if something goes wrong. At United Air Temp, we provide emergency gas line repair and replacement for homes in Severn.

You can detect gas leaks by:

  • Scent: While natural gas doesn’t have an odor, utility companies give it an artificial scent, which smells like rotten eggs, to make it easier to detect a gas leak.
  • Sound: Beware of hissing or whistling sounds from gas appliances.
  • Symptoms: Gas leaks cause fatigue, headaches, nausea, and other symptoms.

If you suspect a gas leak, evacuate your home, call your utility company to shut off your gas supply, and call United Air Temp for gas line service.

Electrical Services

Keeping your home’s electrical systems functioning properly is of the utmost importance to minimize electrical hazards and ensure consistent and reliable power for lighting, refrigeration, HVAC, and more.

Rely on Severn’s trusted electricians at United Air Temp to keep your electrical systems running smoothly. Our solutions include:

  • Whole-home generator installation: Standby generators turn on automatically during a power outage, unlike portable generators, which need to be set up manually each time. Let us install your backup power system for peace of mind, even during extended blackouts.
  • Electric box replacement: Electrical panels need to be replaced every 20 to 40 years. We’ll help you choose a new panel that suits your power needs now and in the future if you add more appliances.

What Our Clients Are Saying
testimonial_image The tech was at my home less than 10 minutes and gone within 20 minutes due to having my A/C up and running. I really appreciate his response to my home and working with my son due to me being out of town, but we spoke on the phone.
testimonial_image The technician arrived promptly, wore a mask, was very courteous and professional. I am generally very satisfied with service by United Air Temp. In addition to good service (they repair well), it is easy to speak to a person, and promptly. Thank you.
testimonial_image Great service! I called because I was under the impression the AC was not working upstairs. Someone came on the same day, checked out the system, and ensured everything was working. He was polite, thorough, and friendly.
testimonial_image Tech was very attentive and professional. He went out his way to explain everything to me as he was doing it. I appreciated him keeping me informed.
testimonial_image The service technician was awesome! He spent the extra time necessary to ensure the leak in our system was fixed, the system fully recharged and everything was functioning as it should. He was extremely thorough and very professional. We are extremely pleased with the result!
