Denver HVAC Repair

If your AC doesn’t turn off when room temperature reaches the temperature set on the thermostat, the problem is generally occurring either at the thermostat or in the electrical system that runs the outside condensing unit. You can use the AC’s circuit breaker to shut off the unit, but that should not be a permanent solution—circuit breakers are not designed to be used like light switches.

First, it is wise to stick with a company that specializes in HVAC services. While many general handyman companies may do some things with AC units, a company that specializes in air conditioning and heating is always a better option. Because air conditioning repairs can be quite costly, depending on the particular problem, it is best to work with highly trained HVAC professionals to ensure quality work.
Most of the time, diagnosing problems is simple and other times it can be a complicated process where the HVAC technician calls in another HVAC technician. The technician may call in an HVAC manufacturer representative. Residential and commercial heating and cooling is important and you want the best possible HVAC air conditioning and heating service. It does not matter whether you have a Carrier Air Conditioner, Trane Air Conditioners, or need a replacement, whatever, it is best to get a qualified technician to look at your system before a decision is made to repair or replace the air conditioner or heat pump systems.
If your air conditioner’s condenser coils, which are located in the outdoor unit, freeze up, your system will not run properly. Poor airflow through your cooling system can cause ice to form on the coils. Obstructions are typically the cause – such as dirty air filters or blocked return air ducts. Low refrigerant could also be the cause, requiring a refrigerant charge. A home AC repair technician can diagnose the issue behind your frozen coils, resolve it, and safely thaw your coils to restore cooling in your home.”

If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. Lastly, a good HVAC service tech will attempt to find the refrigerant leak within the hour’s air conditioning service you are paying for in addition to the refrigerant charge.

Fall is here and winter right around the corner which means soon you will be using your furnace day in and day out. With that said, you cannot expect your heating system to perform at peak levels and provide you with all the warmth and comfort you need if you do not take time out to schedule routine maintenance or an immediate furnace repair should you discover a problem with your system exists.
Per hour service charges are not the only way companies charge their customers. There are also service companies that flat rate their services. Either way, you pay, you want the service and troubleshooting done in a quick and efficient manner with a guarantee. Do your research before selecting a company to provide reliable, honest service to your home. If you know what the problem is then the company can likely give you an estimate over the phone. Some will while some do not. Why? Because they likely want to verify the problem to make sure it is a correct assessment. It can be a complex issue and what you think it is it may not be the problem. So you can expect to pay for a service call and troubleshooting charge. Most HVAC service companies do not give free estimates on repairs.

Before you reach out to local HVAC companies, jot down a few notes. Know the model of your unit and see if it’s under warranty. If so, call the manufacturer first. Then, get multiple quotes for the project in question. Never get less than two quotes for any home remodeling project. Once received, compare all and make sure all include the same work. Check referrals and certifications before making a final decision.


Air conditioners can create a lot of water because they remove moisture from the air. To get rid of this, they have a [usually plastic] drain pipe that comes out of the side of the air handler. Over time, algae can block this pipe and, when it does, the AC won’t work. In fact, some condensate drains have a float switch that won’t let the AC run if water backs-up. Water can also puddle around the unit or flood the area. To deal with condensate problems, please see Air Conditioner Leaks Water, below.
ISO 16813:2006 is one of the ISO building environment standards.[27] It establishes the general principles of building environment design. It takes into account the need to provide a healthy indoor environment for the occupants as well as the need to protect the environment for future generations and promote collaboration among the various parties involved in building environmental design for sustainability. ISO16813 is applicable to new construction and the retrofit of existing buildings.[28]
Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off. Note that this may mean shutting off a circuit breaker that serves the furnace and air handler, and then, near the compressor, pulling out the disconnect block (or shutting off the 220-volt power) to the outdoor compressor.
Central home air conditioner service systems consist of two major components: a condensing unit that sits outside your house, and the evaporator coil (often referred to as an A-coil) that sits in the plenum of your furnace or air handler. The refrigerant in the A-coil picks up the heat from your home and moves it to the outdoor condensing unit. The condensing unit fan blows outside air through the condensing coil to remove the heat. The condensing unit houses the three parts replaceable by a DIYer: the contactor, the start/run capacitor(s) and the condenser fan motor. The condensing unit also houses the compressor, but only a pro can replace that. The A-coil has no parts that can be serviced by a DIYer.
