How quickly can you arrive if my heat or AC quits unexpectedly?

We provide 24/7 emergency AC repair and emergency furnace repair near you. If your system shuts down during extreme weather, call our emergency line immediately, and we will dispatch a technician right away.

Do you handle commercial systems in Greater Landover?

Yes, our technicians deliver professional commercial AC repair and commercial furnace repair to keep local offices, warehouses, and storefronts safe and comfortable.

How do I know if I should repair my system or replace it?

If your unit is under 10 years old and the repair cost is reasonable, a targeted repair is usually your best value. If the unit is over 12 to 15 years old, requires frequent repairs, or uses outdated refrigerant, upgrading to an energy-efficient model typically saves more money on monthly utility bills and prevents repeated service calls.

How often should I schedule HVAC maintenance?

You should have your cooling system inspected and tuned up each spring, and your heating equipment serviced each fall. Bi-annual maintenance helps lower your monthly electric and gas bills, keeps your manufacturer warranty valid, and catches minor wear before it turns into an expensive breakdown.

What to Look for: Signs Your System Needs Professional Care

Prince George's County weather puts sustained mechanical strain on both cooling and heating equipment throughout the year. Recognizing subtle symptoms early protects your system from catastrophic breakdowns and saves you from costly secondary damage.

Call us if you notice any of these warning signs:

Short-Cycling Patterns: The unit switches on and off constantly every few minutes without reaching the target temperature on your thermostat.
Alarming Mechanical Noises: Grinding, screeching, or harsh rattling sounds coming from the outdoor condenser unit or indoor air handler.
Lingering Indoor Dampness: Humid, sticky indoor conditions even when your cooling equipment runs throughout the afternoon.
Moisture Buildup or Frosting: Standing water collecting around your indoor drip pan or visible ice encasing your exterior refrigerant pipes.

Catching these problems early helps protect your compressor, motors, and heat exchangers from expensive permanent damage.

The age, physical wear, and design configuration of your specific HVAC system.
The exact component requiring attention, ranging from simple contactors and relays to complete compressor swaps.
The availability of required manufacturer replacement parts or necessary refrigerant types.
How accessible your indoor unit is within attics, basements, or tight crawlspaces.

Instead of throwing out guesses over the phone, our technician inspects your equipment in person and provides an exact price before beginning any work.

Adding to my positive comments regarding my recent One Hour furnace-installation experience: Odunayo Titunyemi and his team including Keelan Stewart and Thomas were spectacular! They worked carefully, efficently and steadily without so much as taking a break until the job was sucessfully completed. Their work ethic and professionalism exceeded my expectations. If you need a new furnace, I urge you to call One Hour; you are in good hands with Odu, Keelan and Thomas. My new furnace is working beautifully. Kyle and Jeff helped us to make an informed decision about furnace replacement. He was patient, supportive and guided us through the process in a trustworthy, reliable manner - working with his team to coordinate immediate plans to replace our furnace with a quality product (at a very reasonable, competitive price) in an extremely timely manner. I would recommend Kyle, Jeff and the One Hour family every time! That's why I have stayed with them for over 20 years.

This company installed two HVAC systems a while back in my home. My basement furnace would not start up, and a service call was set up. The service technician found that the induction motor was bound up and got it working but was loud. The part was ordered under warranty and was replaced with no labor charges based on some Cust. Sat. issues that I had. It was 8 plus years old. I appreciate the company working with me on that with no charge for the labor to T/S this and replace the part. Both techs. were very professional and did a good job.

We have used One Hour Air Conditioning & Heating for over 10 years and they have been a great company. I recommend requesting Dane he has done a great job, he is curious, professional, and loves dogs. He has been to my house two times for our 6 months maintenance and he just returned for the 3rd time and performed a major part replacement (no error on their part. Issue was a wear and tear issue). They diagnosed and repaired a major component in less than 24 hours. The AC is working great and putting out cold air.
