How Heating and Air Conditioning Works

Heating 

Most central North Las Vegas heating and air conditioning systems are a forced air system which means they send air through ductwork for distribution and recirculate. Radiant systems, on the other hand, create heat from sources like boilers and deliver it through radiators throughout the home. 

Heating products include: 

• Heat pumps
• Gas furnaces
• Oil furnaces
• Fan coils
• Boilers

Air Conditioning 

Whole-home heating and air conditioning systems are central systems that rely on ductwork to deliver cool and warm air throughout your home. A heating and air conditioning system can provide cooling, ventilation, humidity control and even heating which is using a heat pump. 

Typical air conditioning products include: 

• Heat pumps
• Air conditioners
• Evaporator coils
• Fan coils

In installing and repairing a heating and air conditioning system on your home, be sure to insist that the professional technician checks for the correct amount of refrigerant and test for refrigerant leaks. Capture any refrigerant that must be evacuated from the system. Check for and seal duct leakage in central systems.

Measures air flow through the evaporator coil, checks the accuracy of the thermostat. Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously. Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary.

Inspect oil motors and check belts for tightness and wear and tear. Loose belts can increase furnace operating time. Replace frayed or cracked belts if necessary. Two or three drops of oil in the motor will keep it running properly and smoothly (Sealed blower motors require no lubrication). If you have questions regarding your North Las Vegas heating and air conditioning system, check your owner's manual or call a professional technician. Make sure blower doors are replaced properly. This keeps combustion products such as carbon monoxide separate from the warm air circulated through your home. Also, check to see that the exhaust flue to the outside is clear of obstructions and in good condition from the furnace to the roof cap with all connections securely fastened. A professional technician will check it by removing the flue cap near the furnace and water heater and looking through the flue to the outside. The flue cap needs to be replaced securely. If the furnace or water heater is in an enclosed room or closet, they need to get plenty of air. These appliances need ten cubic feet of air for one cubit foot of natural gas to operate properly. Furnace rooms or closets should have door louvers or vents or a duct directly to the outside to provide sufficient combustion air.

Occasionally, clean the outdoor condensing unit by spraying it with a water hose especially at dusty and leafy areas. Check to make sure air conditioning vents inside your home are not obstructed by furniture. Inspect and see that vents in the house are unobstructed. Air in your home needs to circulate easily through the vents. Your furnace works less when heated air is not blocked and the cooler air can circulate back freely. Set the fan speed on high except in very humid weather. When it's humid, set the speed on low; you will get less cooling, but the air circulation will make it feel cooler. It is important to make sure your North Las Vegas heating and air conditioning system works properly for your sake especially during hot and rainy seasons.
