Air handlers, duct work and thermostats work together as a unit. It is possible to have say, the most advanced dual stage compressor, a computerized zone control thermostat, but if your ducts leak, your system is going to be just as inefficient as any other. If you have old single pane windows and inadequate insulation, most of your heating and cooling is just going to leak outside. Therefore it is important that your HVAC system be installed as a unit. Denver HVAC companies should check the integrity of the whole system every time they do any maintenance or you need a new air conditioner condenser. Any errors you may have in the system can be costing you money. As energy prices rise, it is best to take care of any leaks or faulty equipment as soon as possible.

Usually it is best to upgrade the system as a whole. Sometimes when a part fails, it is cheaper to just replace that part or some device than upgrading your central air system. However you do need to consider the risk that the new part does not solve the problem. If the air handler or compressor is aging, one part might fail soon after another. As new air conditioner technologies come into play, many HVAC manufacturing companies like Trane do not even make older parts. So you may need a custom unit to replace HVAC parts.

Both heat pumps and air conditioners use condensers as part of their cooling cycle. An HVAC air conditioner is basically a giant refrigerator for your house. The idea is that the unit absorbs heat from the air, leaving hot air outside and pumping cool air in. The evaporator coil is on one end of the refrigeration cycle. It absorbs heat from inside, while the condenser on the outside releases the heat into the atmosphere. Energy is used to circulate refrigerant through the system, which conducts heat well. As it is forced to expand and contract every time it goes through the compressor. 

Every time you turn off the air handler on your central air unit, the compressor stops and the pressure of the coolant equalizes. However, if you turn the AC unit on within 5 minutes, that pressure will not have subsided yet, and the condenser has to start working much harder against this pressure. This can lead to early air conditioner compressor failure and frequent visits from your Denver HVAC contractor. The air conditioner condensing unit needs a delay timer to stop the system from cycling on and off and damaging the compressor.

 Common Denver HVAC problems caused by cycling Air Conditioners.

If the compressor is repeatedly started at high pressure, it could lock up. As the system strains to start it, common problems include blown fuses, melted capacitors, or general electrical damage to the compressor. A capacitor or fuse is easy to install. Most Denver air conditioning services companies.have spare capacitors and fuses in the truck. In this case, the HVAC tech can fix your machine in under an hour. If the compressor has a mechanical problems, the tech might be able to fix it, but if not you will need an air conditioner compressor replacement. Major damage might require the replacement of the condenser unit as well.

Modern gas furnaces use electrical ignition instead of a pilot light. HVAC manufacturers switched away from pilots because they are slightly dangerous, waste gas, and cause service calls when they go out. The average HVAC companies will re-light your furnace for free, but this is not a call they want to go on.

Electrical ignition is divided into three types. Usually electronically ignited furnaces are more efficient because they are newer and more care went into their design. One type of ignition is the intermittent spark pilot. The system basically just takes sea normal spark pilot ignition system and links it with the thermostat. When the thermostat calls for heat, first the electronic igniter lights the pilot, then furnace operation works normally from there. Once heat is no longer needed, the furnace and pilot stop.

Intermittent hot surface ignition was invented by Honeywell, the masters of pilots and thermostats. Instead of a spark, the system uses a hot loop of wire and electronic sensors to see if the pilot is lit. The sensor is built into the central heating units digital controls.
