The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are commonly installed in tandem with a more conventional form of heating, such as a natural gas or oil furnace, which is used instead of the heat pump during harsher winter temperatures. In this case, the heat pump is used efficiently during the milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower.
With the split system, the evaporator coil is connected to a remote condenser unit using refrigerant piping between an indoor and outdoor unit instead of ducting air directly from the outdoor unit. Indoor units with directional vents mount onto walls, suspended from ceilings, or fit into the ceiling. Other indoor units mount inside the ceiling cavity, so that short lengths of duct handle air from the indoor unit to vents or diffusers around the rooms.
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York.[citation needed] After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.[citation needed]

During a seasonal tune-up, our technicians run diagnostics on every part of your system. We make sure the fans run smoothly, the thermostat is programed to your liking, and that all critical parts are not showing signs of wear. If a component needs replacing, we will replace it for you before it gives out. We’ll even replace the filter for you – one less hassle!


A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
We moved into a new home and had issues with the heating ducts in one of the rooms. We called HVAC based on other yelp reviews. Overall, everyone we dealt with were friendly, professional and knowledgeable: From the people on the phone managing the schedule to the those performing the work in our house. The day before the scheduled work we asked if additional work could be done (clothes dryer duct cleaning), which they were able to accommodate. The people working at the house were on time, very polite, took great care to keep the house clean during the entire job and explained everything when they were finished. I will certainly use HVAC again.

The myth that most people believe is that if you add more refrigerant to the unit it will cool better. This is only true if the evaporator coil is operating below freezing. The unit must have a balanced charge at the correct refrigerant pressure for the temperature and usually, only an HVAC professional can charge your unit properly. Another misconception about refrigerant is that the unit burns it up and it must be replaced from time to time. This is not true. Furthermore, the refrigerant loop is a closed system and barring any leaks the air conditioning system should never need any refrigerant.
Other than mineral deposits, the most common problem is sediment in the water supply. The float inlet valve has a tiny hole that easily clogs. The float is usually made of plastic, and if cracked will fill with water and sink. The valve will be stuck open and the reservoir will overflow. Use caution when scraping deposits off the float. If the deposits cannot be removed, replace the float or it will sink and cause an overflow.

One of the most important ways to maintain the efficiency of your air conditioner is to check on its efficiency periodically throughout the year. In addition to changing your air filters every three months, having a professional heating and cooling professional service your air conditioner before the peak of summer ensures you're not overlooking potential problems. The thorough inspection and tune up of your air conditioner is well worth the low maintenance cost.
Although your AC may continue to work for a time, if you ignore warning signs of air conditioner repair troubles, it can be much more costly to repair in the long term. Diminished cooling capacity not only makes your home uncomfortably warm, but it also raises your utility bills significantly as your unit struggles to maintain the desired temperature ineffectively. A system put under strain is likely to overheat, resulting in major damage. Therefore, it is best to have your air conditioner repaired promptly when you discover signs of trouble. 

If you believe that the ac not working or you’re getting little or no cold air, check these three things first. Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home. If you’ve changed the filter and opened all the registers and you’re still not getting airflow at the registers, deice the A-coil. Move the thermostat mode switch from “Cooling” to “Off” and move the fan switch from “Auto” to “On.” Let the blower run for at least 30 minutes or until there’s good airflow at the registers. Then turn the AC back on to test it. If it works for the next 12 hours, you’ve solved the problem.
