Air Conditioning Repair

Expert Air Conditioning Repair Services You Can Trust

When your air conditioner isn’t working properly, it can make your home unbearably hot and uncomfortable. At Dor-Mar, we provide fast, reliable air conditioning repair services to keep your home cool and comfortable. Our certified technicians have the experience and expertise to diagnose and fix AC problems quickly, ensuring your system runs efficiently.

 

Common Air Conditioning Problems We Fix

If your air conditioner is showing any of the following signs, it’s time to schedule a repair:

1. AC Not Cooling Properly

If your air conditioner is running but not producing enough cool air, it could be due to low refrigerant levels, a clogged filter, or a failing compressor. Our technicians will identify the issue and restore your system’s cooling power.

2. Strange Noises Coming from the AC Unit

Loud banging, rattling, or squealing noises could indicate a loose or broken component. We’ll inspect your system and perform necessary repairs to prevent further damage.

3. Weak Airflow from Vents

If your air conditioner isn’t blowing enough air, it could be due to blocked air ducts, a failing blower motor, or a dirty filter. We’ll determine the cause and restore proper airflow.

4. AC Unit Leaking Water

Excess moisture around your air conditioner may be a sign of a clogged condensate drain line or a refrigerant leak. We’ll address the issue to prevent water damage and system failure.

5. Air Conditioner Constantly Turning On and Off

If your AC is short cycling, turning on and off frequently, it may be due to an overheating system, a faulty thermostat, or an electrical issue. Our team will diagnose and fix the problem to ensure your unit runs smoothly.

6. Frozen Coolant Lines

If your AC unit’s coolant lines are freezing up, it could indicate low refrigerant levels, poor airflow, or a dirty evaporator coil. Our technicians will identify the cause and restore proper function.

7. Low Refrigerant Levels

If your AC isn’t cooling properly, low refrigerant could be the culprit. A leak in the system may be preventing it from operating efficiently. We will locate and repair leaks before recharging the refrigerant.

8. AC Unit Not Level

If your outdoor unit isn’t level, it can put unnecessary strain on your system and cause premature wear. We will assess and correct placement to ensure optimal performance.

9. Organic Matter Clogging Cooling Fins

Leaves, dirt, and debris can clog the cooling fins of your AC unit, reducing airflow and efficiency. We will clean and clear obstructions to ensure your system runs smoothly.

I was so frazzled because we discovered out water heater leaking last nite. It was late, but I got the phone service for Dor Mar and they said they could schedule us for Wednesday. it was Monday nite. I said yes, but I didn't know how to stop the water. We finally figured out to stop the pump to the well. Then I got news that Dor Mar could send someone today, and I was so excited!! Seth got here looked at everything, gave us a very reasonable quote and we agreed. He found a second leak and fixed that. I am very happy with his work, and have calmed down from the nite before.

Terri GuoTerri Guo ★☆☆☆☆ We paid the yearly maintenance fees, they didn’t do the maintenance at all only charged for the money, the maintenance guy said my furnace need to put a UV light to kills the moisture, when he came he told me our water heater need to be replaced and he said if we buy the water heater from them he’ll install the UV LIGHT for free at least 50% off, and clean it for free. After we replaced the water heater they didn’t do it, we still paid a lot money for the UV LIGHT and they didn’t clean it at all so DisappointedResponse from the ownerWe appologize that you have had your maintenace reasxheduled a couple of times Terri, unfortunely with the heat wave we expirienced all working units had to be moved off of the schedule to take care of people without working ACs. As far as the UV light our record indicates extensive notes on where we installed a UV light at one of your properties and that you canceled the one for your home address. If you wish to further discuss your issues you may reach out to our office. Dorothy McCulloughDorothy McCullough ★★★★★ Trevor did an awesome job. He was so professional and nice.Response from the ownerThank you for leaving your tech a great review! John MJohn M ★☆☆☆☆ We experienced some mixups with their after hours phone service but then finally the tech shows up and says "I called my boss and we don't service geo-thermal systems" When we explicitly told them that is the system we had and they show on their web site as servicing/installing geo-thermal. in the end it was just a run around and ended up going with another company that worked out great.Response from the ownerWe apologize for the miscomunication John, we are currently working to correct the issue with our Live Services to further inform them on vthe types of units we do not service. We have also double checked our services lsited on our website and Geothermal units are not on that list. Again we apologize for the miscomunication and are working to ensure this doesnt happen again. Josh HarshbargerJosh Harshbarger ★★★★★ Anthony was so great! Polite, knowledgeable, and efficient. Thanks for repairing our leaks!Phyllis NelsonPhyllis Nelson ★★★★★ Response from the ownerWe appreciate the 5-star rating Phyllis! Tanya ClarkstonTanya Clarkston ★★★★★ Great service! Friendly! Calob B was fast, efficient, friendly & knowledgeable!Response from the ownerThank you Tanya for leaving your tech a great review! Aaron JacksonAaron Jackson ★★★★★ Response from the ownerWe appreciate the 5-star review Aaron! Josh PratherJosh Prather ★★★★★ Good all around.Response from the ownerThank you for the 5-star review Josh! Lee annLee ann ★☆☆☆☆ DorMar does my sister’s HVAC and she has a yearly maintenance contract. SHE is unable by phone or text due to an illness. DorMar came out 3 times during my time as my sister’s Personal Home Manager and POA (in writing). A supply vent has mold and now and they are refusing to come to investigate and/ot provide a quote to fix this serious problem on their work. Even with my sister’s permission in writing and agreement to pay DorMar - they refuse to come to investigate mold on a supply register. Delaying service is going to make it worse and could be deadly.Response from the ownerUnfortunetly Lee, when it comes to scheduling services outside of the maintenace agreement that has been paid for by your sister we have to have consent straight from your her or a legal document stating you are POA and can make decisions for the property. Our system tracks every phone call and we have it on record that on 6/27/2025 in a phone call between you and one of our CSRs that you are not POA this means you are not able to schedule these appointments. Legally we are not able to schedule anything without that documentation or consent straight from your sister. If you are able to provide either of those we will be happy to schedule a service to inspect the issues going on in the Ductwork/HVAC in the home. WAYNE LWAYNE L ★☆☆☆☆ My ac stopped working this evening. This company claims 24 hours service but reluctant to provide service for 2 days. What happened to prompt service? The lady on the phone couldn't speak clear English. This company claims prompt service but fails to do so.Response from the ownerUnfortunetly Wayne with the heat wave we have had this past week our schedule has been booked a couple days in advanced for this entire past week. We always try our best to do same day service but our schedule can still book up. Dorothy MoorheadDorothy Moorhead ★★★★★ Service call yesterday for issue of short run and inefficient cooling after being inspected 3 weeks ago and deemed in good working order resulted in discovery of king valve being mostly closed and starving system of coolent then the system being bleed down to where it had to be shut down due too tech having trouble disconnecting equipment (reverse threads) .As tech didn’t have coolant on His truck - received text schedule for today between 8-12 to recharge the system - now 1:25 and still waitingjs_loader
