Professional Air Conditioning Installation & Replacement Services

If your air conditioner is outdated, inefficient, or frequently breaking down, it may be time to upgrade to a new air conditioning system. At Dor-Mar Heating, Air Conditioning, Plumbing, and Water Treatment, we provide expert AC installation and replacement services to keep your home cool and energy-efficient. Our certified technicians will help you choose the best new AC unit for your home and install it with precision.

Signs It’s Time for a New Air Conditioner

Not sure if you need a new AC unit? Here are some signs that it’s time for a replacement:

1. Your AC is Over 10-15 Years Old

Older air conditioning systems lose efficiency over time. If your AC unit is over a decade old, upgrading to a new air conditioning system can save you money on energy bills and improve cooling performance.

2. Frequent Breakdowns & Costly Repairs

If you find yourself constantly scheduling repairs, replacing your unit may be the more cost-effective solution. Investing in a new AC unit can eliminate the hassle of frequent breakdowns.

3. Rising Energy Bills

An outdated or inefficient AC system requires more energy to maintain comfortable temperatures. A new air conditioner with high SEER ratings can reduce energy consumption and lower your monthly bills.

4. Uneven Cooling & Hot Spots

Are some rooms in your home warmer than others? An aging system or improperly sized unit may struggle to distribute cool air evenly. A properly sized new air conditioning system will keep every room comfortable.

5. Loud Noises & Strange Smells

If your AC is making loud noises, rattling, or emitting burning odors, it’s a sign of failing components. A new AC unit will operate quietly and efficiently.

Choosing the Right New Air Conditioning System

Selecting the right new air conditioner for your home is essential for efficiency and comfort. Our experts will guide you through the selection process based on:

  • Home size & cooling needs – Ensuring the system is properly sized for your home.
  • Energy efficiency (SEER Rating) – Higher SEER-rated units provide better efficiency and cost savings.
  • Budget & financing options – We offer affordable solutions to fit your budget.
  • Smart thermostat compatibility – Upgrade your cooling system with modern controls.

Our Air Conditioning Installation Process

At Dor-Mar, we make installing a new air conditioning system hassle-free with our step-by-step approach:

1. In-Home Consultation

We assess your current cooling needs, home layout, and budget to recommend the best new AC unit for you.

2. Proper Sizing & Unit Selection

An incorrectly sized system can lead to inefficiency and premature wear. We ensure your new air conditioner is the perfect fit.

3. Professional Installation

Our licensed technicians install your new air conditioning system according to manufacturer guidelines, ensuring optimal performance and longevity.

4. System Testing & Optimization

We test the new AC unit, calibrate the thermostat, and check airflow to confirm proper operation.

5. Customer Education & Maintenance Tips

We walk you through how to operate your new air conditioner and offer maintenance tips to keep it running smoothly.

Benefits of Installing a New AC Unit

Upgrading to a new air conditioning system offers several benefits:

  • Lower Energy Bills – Modern AC units use less energy and operate more efficiently.
  • Improved Comfort – Even, consistent cooling throughout your home.
  • Quieter Operation – Enjoy a peaceful home with reduced noise levels.

Dor Mar Heating & Air ConditioningExcellentDor Mar Heating & Air Conditioning4.6★★★★☆ Based on 1359 reviews fromSee all reviews review us onBryn SmathersBryn Smathers ★☆☆☆☆ Make sure prior to the job you discuss price, process and have it in writing. Our hot water tank needed a new valve which was covered under warranty. Our service maintence package with Dor Mar covered the first hour of labor for the repair. They sent me a bill for the hour labor it took them but I was told it was covered. Very discouraged by this and will be cautious with the next repair. Not good practice especially to a customer who bought the hot water tank through Dor Mar.Response from the ownerUnfortunely we are at the mercy of the manufacturer when it comes to what is covered under warranty, we are sorry that it was not discussed prior to your repair call that you would owe the labor to put the part in, standard protocall includes a phone call from our parts department to discuss costs before hand. Our records indicate you had discussed the price for the parts call before excepting the estimate for the work. Your labor for the Daignostic call was covered under your Service Contract. We appologize for any misunderstanding and hope you continue with Dor-Mar!

Elijah WilliamsElijah Williams ★★★★★ Dor Mar hires great prospects who provide excellent service. My tech, Preston, came and knocked the job out of the park — I’ve had 3 different companies come out and inspect my heat pump several times but we got no where.

Please reach out to our Customer Satisfaction Manager kayden@dormarhvac.com or call into the office and ask for her directly so we may get to the bottom of this. Juanita RamseyJuanita Ramsey ★☆☆☆☆ Dor Mar sent out a employee to drain my hot water heater as part of a maintenance program that I paid for. That employee spent most of the time walking around the inside of my house (my hot water tank is in the basement with an outside access only) taking pictures of all of my plumbing. He did not ask to do this he just started taking pictures saying he was supposed to. He opened my cabinet under my sink and wanted to know why I had a bucket there. (it was to carry cleaning supplies in when cleaning around the house)Then he told me that there was a problem with my tank since he emptied it and it was leaking. I asked him how much it would cost to fix it and he immediately said $2700.00. I told him just to turn the water off to the tank and to just leave. He had placed a bucket under where it was leaking, and he said I won't have hot water. If he turned it off. He then tightens the screw a little more and then it quit leaking.Another problem I had was I told him he could park beside the house (I showed him where) but for some reason he just wanted to walk through the front door and through the house and then out the back door. He did this about 3-4 times.Finally, when he was done, I opened the gate so that he wouldn't walk through my house again and he went straight to the front door saying he was so sorry, but he had lost all of the pictures that he took and had to come in to retake them all again. At this point I was ready to call the sheriff to escort him off the property. I did let him take the pictures and finally he was off.He was polite when talking to me I have no issues there, but all the other stuff was unnecessary... He was there to drain my hot water tank not to do a photo shoot. I will try to come to the office on Monday I am still extremely upset about this. IT IS NOT THE WAY TO DO BUSINESS!Response from the ownerFrom your description of what the technician did while in your home perfectly describes our Plumbing maintenance Juanita. The plumbing maintenance includes a check on the entire plumbing of the home and the flushing of your hot water tank, we do apologize if that was not properly explained to you when your service was booked. It is also unfortunate the tech couldn't follow the directions you offered to not have to walk through the home and we apologize for that, over all we hope this gives you some ese on what was done by the tech as he was just doing his job. S HawkinsS Hawkins ★★★★★ Anthony was greatResponse from the ownerThank you for leaving our tech a great review! Angela SeymourAngela Seymour ★★★★☆ The service was great. But they don't honor their service windows. My service windows was 12-4 and I get a message at 9:40 that the tech was on the way. I had to rearrange my schedule to fit in the cleaning. Luckily I was close by and could make it to the house in time.Response from the ownerWe apologize there was an issue with your scheduling, we always try our best to make our time frames, in the future wed be more than happy to have the Tech wait for the scheduled time frame had we known it was an issue for you to make the appointment earlier.

Tara BeyerTara Beyer ★★★★★ Response from the ownerThank you for the 5-star rating Tara! junior pjunior p ★★☆☆☆ Techs are great and do a very good and thorough work, but their billing and customer support will rip you offResponse from the ownerIts unfortunate that you had an experience with our customer service reps that made you feel that way, If could you please reach out to the head of our Customer satisfaction team to provide some more details on your situation so we can better ensure it doesn't happen again it'd be greatly appreciated. You may reach her by email - kayden@dormarhvac.com or call our office @ 740-345-6639 and ask for her directly.
