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!

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.

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.
The company says its technicians are certified by Lennox and NATE.
The rating, reviews, and round-the-clock hours
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.
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.
