These guys charge a lot and never get anything done. The Lennox systems they install are expensive and do not perform. They promise a lot, do not deliver and take a lot of your money. Stay away.

Dalco team did a great job replacing my ac unit. Management was very involved from start to finish. The techs were kind and considerate, and answered all of my questions. We are happy to not be melting in this Texas heat! Thank you for your service.

UNPROFESSIONAL AND UNRELIABLE. a) This business voluntarily confirmed an 8 AM appointment with me the day before. b) Assured me they were on the way the day off the appt. c) Did not show up to the appointment, did not communicate that and blocked my number. Edit: The technician arrived later, identified the issue as a bad capacitor, was very professional in their communication and finished in time. Revising my review to 4 only because they were late and did not preemptively communicate that.

Had a noise in condenser unit at my leased property. Called to have it checked out. Service technician scheduled visit with tenants and then sent me an estimate for a full replacement of the entire system - $11K. No feedback on the noise problem. Got a second opinion and was told that the system is old but running. The noise in the condenser unit was from a loose part. Criminal!

Signed up for air conditioner check To make sure all was good when purchases my new home. They quoted a price for 2 checks in one year. Said great. They came out checked inside left due to rain said would be back next day for outside. No show. Called the 3rd day said would send someone. Called serval times after that still no shows. Wouldn’t recommend justo. The fact they can’t keep appointment a

To say I'm disappointed is an understatement.. I reached out to Dalco after buying an investment property. I just needed a company to do biannual maintenance for my unit. They originally came out on a Monday, checked the inside unit and a sudden surge of storms delayed the checking of the outside unit. I understand they needed to come back at a later date, weather permitting, but we're pushing two weeks and I have yet to have the outside unit checked and no one has returned my calls. I can't believe in this economy I'm having to beg a company to take my money.

I needed an emergency service towards the end of the day. Kate made sure the techs came out within that hour . They got my unit up and running and were very kind and knowledgeable. Thank you to the wonderful technician’s for their hard work and helping me understand what was going on and for not charging an arm and a leg for the service. I will be recommending them to family and friends. Thank you dalco.

You won't believe this happen.. This company missed 2 appointments with us. They made us wait on 3/11 and 3/12 from 9-11am and never showed up. When we called them, they said the technician was out sick, and knowing that they didn't cancel his appointments. When I spoked with the supposed "manager", obviously upset by missing 2 days at work, she ended up saying I could go to a different company and HUNG UP ON ME! Can you believe this?

My heater went out last night so I called this company in the morning and within 30 minutes there was a technician at my house. They let me know the service charge up front and gave me an estimate before any work was done. I am so impressed with how efficiently the technician worked and how well he knew his inventory. Jonathan was great and we will definitely use this company again!

I found Dalco via the manufacturer of my HVAC. I needed help quickly, because I'm in Dallas, TX suffering in this heat. The company my Home Warranty Company sent was HORRIBLE. Ivan with Dalco was awesome. He explained everything he did AND he gave me tips on best practices I should use. I signed to a maintenance agreement with them on the spot. I need a company licensed to service Lennox HVAC systems.

Dalco has been great to work with. In the midst of these crazy freezes, every other plumber pricing was sky rocketing while Dalco still provided exceptional services at fair prices. They have truly been a blessing to all our clients and I would recommend them to anyone.

We needed our ducts cleaned so I called JD Points and even though they were slammed, he got someone out to our house in just a couple of days. They were on-time, kind, professional, and the quote they gave us for a new HVAC system was so much lower than the other company we had out a few months ago. After my experience I wouldn’t use another HVAC company. Highly recommend!

I have been using DALCO as an integral part of my construction company for years. JD has personally assisted me with outstanding customer service both for me and the customer sites that I send him to. The various levels of employees and staff have been nothing but professional in their interaction, efforts and workmanship.

About Dalco Air Conditioning & Plumbing
Dalco Air Conditioning & Plumbing says it has worked in Dallas since 1963. Its work includes air conditioning and heating, with installation, repairs, and maintenance for residential, commercial, and industrial customers.
Air conditioning and heating work in Dallas
The company identifies maintenance as part of its work and says it installs new systems as well as repairing and maintaining existing equipment. It also names Lennox among the systems its technicians work on. Its description includes plumbing alongside HVAC work, though its stated HVAC services focus on air conditioning, heating, installation, repair, and maintenance.
Dalco reports four generations working in the family business. That tenure is paired with a Dallas focus rather than a separately named service territory. The company’s hours show it open 24 hours a day, seven days a week.
In Dallas, electricity heats 65% of housing units in 2024, per the American Community Survey. NOAA normals for 1991-2020 give Dallas a mean temperature of 66.8 degrees F, with an average high of 77.3 degrees F and an average low of 56.2 degrees F.
Its technicians are certified by Lennox and NATE.
The rating, reviews, and round-the-clock hours
Dalco has a 4.3 rating from 43 reviews. Reviewers describe successful air-conditioning replacement and restoration of cooling, along with helpful phone communication and technicians who answered questions.
Other reviews raise concerns about appointment timing, follow-up communication, and estimates for replacement work. Several accounts describe delayed or missed visits before later service was completed. The feedback therefore covers both completed repair or replacement work and the consistency of scheduling and communication around it.
For a Dallas buyer comparing HVAC contractors, the measurable basics are a 4.3 rating across 43 reviews and 24-hour daily hours. The company’s stated work across new-system installation, repairs, and maintenance, plus its long Dallas tenure, rounds out the information available for assessing the fit.
Services, brands and warranty details come from the company's own website. Ratings, hours and reviews come from Google. Town figures come from the US Census and NOAA.
