If you smell natural gas, call your Gas Company, open windows and doors and exit the home immediately. Contact G & L Services for repairs or service if needed.

G & L Services recommends annual maintenance on both your heating and cooling systems. Cooling systems should be checked prior to the hot summer months, and heating systems should be checked prior to the cold winter months.

Air conditioners are a closed system and should not require adding refrigerant. If the equipment is low on refrigerant, there may be a service-related problem or a leak in the system. Refrigerant leaks can be repaired in some cases or may require equipment replacement. Contact G & L Services for repairs or service if needed.

Routine maintenance lowers utility costs, maintains capacity and extends equipment life. G & L Services VIP Maintenance Plan offers a 15 percent discount on parts and priority service. 

Keep your filters clean. Keep leaves, foliage and other debris from building up around outside air conditioners. It is important to schedule routine maintenance, safety inspections and repairs.

It is generally recommended to set the fan motor to the "auto" position.

Ductless air conditioning doesn’t use air ducts to transport cool air through a building. Instead, indoor air units blow the conditioned air directly into the room or area they’re installed in.

We install all types of HVAC systems and ductless mini-splits. Schedule a quote to find the right fit for your home by calling G & L Services at (423) 242-8257.

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas produced by partial fuel combustion which, in turn, is frequently caused by insufficient access to oxygen. Appliances relying on natural gas, charcoal, wood, or kerosene are common sources of CO gas, especially if they are not running correctly or have been installed incorrectly. CO is poisonous to the body and is lethal at high levels or prolonged exposure.

Initial symptoms such as nausea and fatigue are often mistaken as a result of the flu. But CO gas exposure can progress, potentially leading to confusion, organ damage, or even death. Other symptoms include:

• Headaches

• Dizziness

• Chest pain

• Vomiting

If an air freshener isn’t doing the trick, there may be microbes or contaminants nearby producing the unpleasant odor. Bacteria and mold are common sources, but they can be resolved with the sanitation properties of a germicidal UV light. They are particularly effective against odor-producing microorganisms and viruses.

Scheduling frequent tune-ups on your HVAC systems can help extend your system’s life span, which is a big step for personal sustainability. Smart thermostats also control the daily temperature of your home and help with zoning, which reduces the impact on your systems by not having major temperature changes. Using energy-efficient HVAC systems can also be a big step in making your HVAC eco-friendly. High-efficiency HVAC systems are usually ENERGY STAR certified, which lowers carbon emissions by reaching high performance for less energy.
