Furnace Repair Co


Over the Labor Day weekend our hot water heater decided it was time to say good bye. Since we had our fall check the week before, we called Nerthlings. I cannot say enough good things about how this situation was handled. The technician, Dwain, was knowledgeable, friendly, and quite helpful without being pushy. Our questions were answered clearly. I am never made to feel that this is something...

We’ve been serving the Charlotte area for over 45 years, and our customers are always treated with respect and professionalism.

See below for some reasons why we’re the best air conditioning and heating service company in Charlotte and surrounding areas:
Reinstall the access panel and disconnect block. Turn on the circuit breaker and furnace switch. Then set the thermostat to a lower temperature and wait for the AC to start (see “Be Patient at Startup,” below). The compressor should run and the condenser fan should spin. If the compressor starts but the fan doesn’t, the fan motor is most likely shot. Shut off the power and remove the screws around the condenser cover. Lift the cover and remove the fan blade and motor (photo 7). Reinstall the blade and secure the cover. Then repower the unit and see if the fan starts. If it doesn’t, you’ve given it your best shot—it’s time to call a pro.
Circulating refrigerant vapor enters the compressor, where its pressure and temperature are increased. The hot, compressed refrigerant vapor is now at a temperature and pressure at which it can be condensed and is routed through a condenser. Here it is cooled by air flowing across the condenser coils and condensed into a liquid. Thus, the circulating refrigerant removes heat from the system and the heat is carried away by the air. The removal of this heat can be greatly augmented by pouring water over the condenser coils, making it much cooler when it hits the expansion valve.
Dehumidification (air drying) in an air conditioning system is provided by the evaporator. Since the evaporator operates at a temperature below the dew point, moisture in the air condenses on the evaporator coil tubes. This moisture is collected at the bottom of the evaporator in a pan and removed by piping to a central drain or onto the ground outside.
It's quite possible that you need a new HVAC unit, but we can't tell for certain. We will need to do a complete inspection of the property and conditions the unit is in. Because of the multiple maintenance aspects regarding HVAC units that could and will prevent the unit's proper functions. We are the experts in diagnostics and repairs. If your HVAC unit is at all salvageable... before we are done we'll make sure that it operates in peak condition.
Beware these aluminum clad wood doors. The wood is particle board. Why would anyone make a storm door out of particle board? They don't seal it in any way, it gets wet between the aluminum cladding and boils and blisters the aluminum and looks terrible in just a few years. I have two Larson's and they were horrible doors almost from the start. I've seen reviews and EMCO is the exact same way. When your storm door needs a storm door, you bought the wrong door.
