Service and Repair — Honest pricing.
Q) What will it cost?
Global Mechanical quotes the price of repairs and/or maintenance up front so you, the customer, know what to expect before the job is finished and you have choices. We utilize a flat rate on all parts. Flat rate pricing is determined by adding the average time to install the part with the list price of the part. You can be rest assured that Global Mechanical will keep repair prices reasonable.
Q) Do I need to have my furnace or air conditioner serviced every year?
Having your equipment serviced on an annual basis can prolong the life of your equipment and save you money on operating costs.
Q) How will cleaning my air conditioner help?
Cleaning your air conditioner can save you as much as 25% on A/C operating costs. The purpose of the condenser coil is to get rid of the heat that was collected from your house. A dirty coil will cause your system to run longer than it should and could shorten it’s life expectancy
Q) I could clean the air conditioner myself, why should I pay a company do it?
Besides cleaning your air conditioner, a Qualified Technician checks the system to insure that it is operating correctly.
Q) My air conditioner is running fine, why should I have it checked?
It may appear to be running fine but you really don’t know that. If your system is checked, a Qualified Technician may be able to detect problems before they occur. Something as small as a contractor that is worn or pitted can create some major problems. Bad contacts on the contractor can create higher amp draws and raise your utility bill. High amp draws can also cause a fire in your system resulting in a costly repair bill.
Q) I have to add refrigerant to my system every year, why does it use it up?
Your air conditioner is a sealed system. If you have to add refrigerant, you have a leak. This leak should be repaired.
Q) Why should I repair a leak?
Just adding refrigerant to your system when it is low is not a good idea. If your air conditioner is low on refrigerant, it could result in major repair bills not to mention that the escaping refrigerant is damaging the ozone layer. When an air conditioner is low on refrigerant the system will run longer and not be able to cool your house. Your system may “ice up”. The ice will not allow air to pass through the evaporator coil. The purpose of the Evaporator coil is to collect the heat in your house. As refrigerant enters the evaporator coil it boils and becomes a vapor collecting the heat from the air. If air doesn’t flow across the coil, all of the refrigerant can’t boil. Liquid refrigerant could flow back to the outside unit and wash the oil out of the compressor resulting in shortening the life of the compressor. Water from the ice may leak down onto your circuit board or controls in the furnace. This could cause some major problems that could have been avoided.
Q) What else can cause the system to “ice up?”
There are many reasons that your system can “ice up” but there are 2 main causes. One is low or no air flow. The most common reasons for low or no air flow is from a dirty filter, dirty blower wheel or bad blower motor. Filters should be checked monthly and replaced or cleaned on a regular basis. A dirty blower wheel is the result of poor filtration. Dirt and dust can damage your blower motor and shorten it’s life. The second most common reason that your system will “ice up” is low refrigerant.
Q) Why should I have my furnace cleaned?
A dirty furnace can result in a dangerous situation. If it has a lot of lint & dust around the burner area, it could cause a fire. The blower is also checked during a cleaning to make sure the air flow is correct. Low air flow can damage the heat exchanger because of a high heat build up.
Q) I can clean my furnace myself, why should I pay a company to do it?
A Qualified Technician will not only clean the furnace but also make sure that it is operating in a safe manor. Besides checking all of the controls and wiring the technician will also inspect the heat exchanger for cracks that could result in serious injury or even death from Carbon Monoxide poisoning.
Q) My furnace is new, why should I have it checked?
Improper operation of your heating system could raise your utility bill and create problems within the furnace itself. If the damage is from negligence, the manufacture may not cover the repair under warranty. The repair will come out of your pocket. Think of it this way, when you buy a new car you change the oil every 3,000 miles. If you don’t and the car breaks down, the warranty is VOIDED! Your Heating and Air Conditioning system should be regularly maintained with annual check ups to avoid costly repairs.
