Who We Are

Hello, and welcome to Marathon Mechanical Air Conditioning!

I’m Andy, and I have been selling, installing and repairing air conditioner systems for over 25 years.  Whether you need a repair, or need a new system, we can help.  We carry all brands of air conditioners as well as parts for any system that needs fixing.

Any time you need us, we are there. We offer emergency service. No job is too big, nor too small.

How is your air conditioning system?  Feeling too hot, these days?  Or, maybe, your air conditioning just uses too much electricity?  Well, systems have advanced a lot of recent years to be more energy efficient.  Perhaps it is time for a new one.  Or, maybe you just need yours repaired.  Whichever you need, we can help you.

In either case, Marathon Mechanical is the place for you.  We are a small, family-owned business that offers you the best in customer service and speedy service as well.  Don’t wait for too long in the heat.  We are honest, and will tell you if it is time for an upgrade, or if a repair will do.  We offer both commercial and residential service, and carry all makes of Air Conditioners and HVAC systems, and parts, including Carrier, Trane, and Goodman.  Repair or replace, we will give you an honest opinion as to which is better for your particular situation.  Our prices are the better than larger companies.  If you live in the Greater Dallas/Fort Worth metroplex, give us a call for a free quote and see!

Air Conditioning Service

Did you know the highest heat ever recorded here in Dallas was 113 Fahrenheit during the heat wave of 1980?  While, luckily, we don’t get temperatures that extreme most years, our summers do get hot.  Usually, we average up to 96 degrees Fahrenheit during the summer.  That is enough that you want your air conditioner to work, and to work well.


Heating Service

Did you know the highest heat ever recorded here in Dallas was -8 degrees Fahrenheit in 1899?  While, luckily, we don’t get temperatures that extreme most years, our winters do get cold.  Our typical low temperature is in January at about 37 degrees Fahrenheit.  We get everything in our four seasons from Thunder and Lightning, to floods, tornadoes, and even hurricanes.



Walk-In Refrigerator/Freezer Repair

If you own a restaurant, you know one of your biggest costs is the food you keep in cold storage.  If you see a temperature above 40 degrees Fahrenheit in your refrigerator, or 0 degrees Fahrenheit in your freezer, you know that you need help.  And fast.  That spoiled food, you see as dollars being tossed in the trash.
