Air Conditioning Services

Nothing beats the heat of a hot, humid summer day like a highly efficient air conditioner. But as time passes, the wear and tear your AC goes through eventually leads to issues such as short-cycling, refrigerant leaks, and overall inefficiency.

To keep your home from feeling humid and uncomfortable, United Air Temp offers a wide range of air conditioning services, including:

In addition to central air conditioning systems, we also offer installation, repair, and maintenance for ductless mini-splits and heat pumps! These systems offer heating and cooling capabilities, precise temperature control, and increased energy efficiency!

Enjoy cooling comfort with the help of UAT in Greenbelt. Get in touch online or call (410) 413-3549 to schedule air conditioning services.

Emergency Heating Services

Reliable home heating starts with choosing the right unit for your heating needs, efficiency goals, and home specifications. At United Air Temp, we offer free replacement estimates and install the following systems according to specifications:

Annual heating tune-ups will then keep your system in optimal condition. However, if your heating unit is ever on the fritz and needs repair, a UAT technician can inspect and identify the cause of unusual sounds, uneven heating, or burning smells.

Call (410) 413-3549 or reach out online to schedule heating service in Greenbelt. We’re available for emergency heating repair!

Indoor Air Quality Services 

The air you breathe in your home can be up to 5 times more polluted than outside. That’s because bacteria, allergens, dirt, chemicals, and other airborne particles get trapped inside and circulate through your ductwork.

Breathing in high concentrations of these particles can contribute to chronic health conditions over time. Even in a short period, they can cause annoying allergy symptoms.

With indoor air quality services from United Air Temp, you can get back to breathing fresher and cleaner in your Greenbelt home! We install:

  • Whole-house humidifiers and dehumidifiers
  • Attic fans
  • UV light purifiers
  • Ductwork services

We also perform R-22 conversions for air conditioners that run on Freon refrigerant. Previously the most popular refrigerant, R-22 negatively affects the environment and is no longer produced. We’ll upgrade your air conditioner to be compatible with Puron, an eco-friendly refrigerant that’s better for your home’s indoor air quality and the environment.

Make your home’s indoor air safer to breathe for you and your loved ones and schedule indoor air quality services in Greenbelt.

Drain & Sewer Services

Your water, drain, and sewer pipes are your plumbing’s infrastructure. United Air Temp provides effective drain and sewer services throughout Greenbelt.

  • Video camera inspections allow us to quickly identify the source and cause of any blockage.
  • Drain cleaning from a professional will clear blockages and stop standing water in your fixtures.
  • Hydro jetting is a technique we use to remove sewer line clogs and excessive buildup that drain snakes and augers can’t clear.
  • Sewer line replacement and repair may require a trenchless or traditional approach to address tree root intrusion, a line break, or deteriorating pipe materials.
  • Sewage ejector pump replacement and repair aid drainage flow for properties with a main sewer line or basement fixtures that are lower than the municipal sewer line.

Keep your drains and sewer line clear with the professionals at United Air Temp. Call (410) 413-3549 or contact us online today.

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!
