All Air Conditioning, Heating, Duct work Guaranteed

Ruben Carmona, owner of L J Air Conditioning, treats you right! Ruben will personally come to your home or commercial building and give you a written estimate on your job. Your project will be completed quickly, economically, and professionally.

Custom Sheet Metal

HVAC Ducts and Vents

Let L J replace your worn out heating and cooling ducts so that they run efficiently and keep your energy bills down. They can also adapt your duct work when you replace your unit or upgrade it to refrigerated air. Ducting is available in standard galvanized and in stainless steel materials.

In addition to custom ducts for residential and commercial HVAC systems, L J Air Conditioning can fabricate other sheet metal products. Is one of your evaporative cooler sides badly rusted so it delivers less cool air now? L J can create a new panel and install it for you. (Or just bring in the old one and they will have a new one ready for you within a couple days.) When you need any kind of sheet metal work, think of L J Air Conditioning first.

Heating and Cooling

Convert your existing swamp cooler to refrigerated air

L J Air Conditioning installs and services many brands of heating and cooling equipment, including Rheem, Ruud, and Trane. Are you ready to upgrade to refrigerated air to keep your cool on those sweltering El Paso summers? Converting your current evaporative cooler to refrigerated air is L J's specialty!

Refrigerated air means your home stays 10 to 20 degrees cooler than evaporative coolers, and it does not add humidity to the inside air. If needed, they have can also modify your duct work and build a new roof jack or stand for wall entry. They handle your project from start to finish.

Licence experts for repairs and service

Air conditioning repairs may include new motors, fans, pumps, refrigerated air parts of all kinds, new housing parts, pads, and controls. Call for a free written estimate from L J's licensed experts in heating, venting, and air conditioning (HVAC). Don't let an unlicensed uninsured "handyman" work on your furnace, evaporative cooler, air conditioning, or duct work. They can create even more problems that will only cost more money. If they knew really the trade, they would be able to pass the exam for the HVAC license.

Custom Roof Jacks and Stands

Roof jacks made to fit your cooling or air conditioning unit

Unfortunately, there is rarely a standard size for air conditioning units. Whether it is refrigerated air or an evaporative cooler, you may need to adapt the new unit to the slope of your roof or to precisely fit into the existing wall opening. L J Air Conditioning and heating can build a sturdy, custom built roof jack or air conditioning stand just for you! Even if you are installing it yourself,
let the experts create the unit that will securely attach your air conditioner to your home or commercial building.

Replace your worn our, bent, rusted roof jack now

L J can also fabricate a duplicate roof jack if yours is damaged from rust or wind damage. Don't take a chance of damaging your unit or roof. Or worse, falling off the roof during a windstorm and injuring someone.

Your Job Completed the
Right Way

In a city where many inexperienced people ask for work even when they are not qualified, it's great to know that L J Air Conditioning offers great installations and repairs at affordable prices! Why take a chance on someone who is not licensed? To earn a license means showing expertise in the industry or trade, and to fulfill all state requirements. A license also shows a dedication to professional service and quality workmanship. Following regulations insures against further damages to your property; especially fire damage from improper electrical work.
