HVAC & Refrigeration FAQ

How many years can I expect to get from my Air Conditioner and Furnace?

About 10-12 years is normal in this part of Texas. This is a harsh climate, so regular maintenance is essential to get the most from your equipment. With current utility prices you should consider replacing sooner rather than later. Newer, higher efficiency equipment can help keep utility price increases down.

Can NEW Equipment really Save me Money on my Utility Bills?

Absolutely; by as much as 50%! At today’s utility prices it doesn’t take long to recover the cost of a new air conditioning and heating system. Call us at (972) 424-2929 to find out more.

What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio. Think of it as similar to mileage ratings for cars and trucks – a higher number is better. For example, a 14 SEER rating unit will provide about 40% better efficiency than the 10 SEER units typically installed during the early 1990s. For even greater utility savings, we offer equipment rated up to 18 SEER.

What is PURON?

PURON is an environmentally friendly refrigerant used in many refrigeration systems.

What is a 2 Stage Gas Valve?

A 2 Stage gas valve is a valve that meters gas into your furnace and it has two stages; a high stage and a low stage. For more information, please call LCS at (972) 424-2929.

Should I have a Preventative Maintenance Agreement?

Think of your air condition and heating system like a car. You wouldn’t run your car for 10 years without oil changes or inspections. Your heating and cooling system is a machine that needs regular service for a long durable life.

Is it possible to have too big of an Air Conditioning Unit?

An oversized unit will provide cooling faster, but will not remove humidity adequately. Also, if your ductwork isn’t big enough to match the air conditioner the airflow will be too slow and you could freeze the coil, which would make it cease to function at all. Size matters; bigger isn’t always better.

Yes, we will work with you and schedule work that needs done so that it will not slow down your business! If there is an electrical problem that is prohibiting you from running your business, we will have it back up and running as soon as possible.

Can you offer suggestions to save money on electric consumption?

Yes, we can do an estimate of your location to determine LED upgrades, and retrofits, as well as timers, photocells, and motion sensors to help cut costs on your lighting usage.

Do you work on equipment?

We offer services for all power, lighting, panels, and receptacles for any type of location. We do not specialize in equipment repair, however if it is a problem with a power cord, or a faulty part for a piece of equipment that we are able to replace, we will certainly be able to help.

Commercial Plumbing FAQ

What is a fiber-optic pipeline video inspection?

A fiber-optic pipeline video inspection is a diagnostic process whereby a high-resolution fiber-optic video camera is inserted in a pipeline to view the pipe from the inside. It takes the guesswork out of diagnosing a pipeline problem and can pinpoint exactly where a problem is and exactly how to fix it in the most cost-effective manner. LCS has several of these cameras and qualified technicians to run them.

What is high pressure pipe jetting?

This is the most effective method of completely cleaning the inside of a pipeline. Water is pumped through a nozzle at up to 4,000 psi to actually scour the inside of a pipe, thereby removing roots, scale, grease, dirt and other obstructions.

How can I tell if I have a slab leak?

If you’ve checked the above items and found no leaks, you should check your water meter. This will usually be found in the front yard and will usually appear as a concrete or metal rectangular lid at a grade level. Open the lid and locate the meter inside. This may require removing some dirt to access the face. With no water running at the facility (dishwashers, laundry, toilet, refilling, etc.), check the dial face for any movement. Many meters have a “leak detector” which appears as a small black triangle or a small white wheel. If this is spinning or there is any movement on the dial, this indicates a leak in your water pipe system.

What is a repipe?

A repipe is a complete replacement of the incoming fresh water system in a home or business from the water meter or well to all plumbing fixtures. As severe as it sounds it is actually a very common procedure. It is necessary in situations where the plumbing pipes have begun to leak due to deterioration, or when low pressure due to calcification is present in pipes.

At what temperature should I set my water heater?

Manufacturers recommend setting water heaters at 120° degrees (F). This will prevent accidental scaldings.

Should I use a caustic drain cleaner before calling a plumber?

We do not recommend EVER putting caustic drain cleaners in drains. If a drain is running slowly you may use a biological product to help clear it. We recommend BIOOne. Use according to directions. If it is completely stopped up we recommend you call a professional to unclog your line. Pouring caustic solutions into drains can ruin pipes and cause severe burns to anyone working in the drain after application.

What are my payment options?

New customers are given the option of paying with either Visa, MasterCard, American Express, Discover, Checks, or Money Orders. Repeat customers in good standing are offered a “30 Net” option..
