Denver HVAC Repair

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.
I'm very glad that I found another guy to come replace the circuit board and put it away from the water, fix the water leak, and also find and fix another impending failure.  All of that was for much less than HVAC Service wanted to charge for repair or replacement. The other guy did a great repair, so I'm confident it will not break down again, but if it does, I will not call HVAC Service. Don't get suckered by their Yelp Deal.

Eventually, every homeowner experiences a malfunction in their heating unit. It’s a cold morning and you hike the thermostat up like you usually do to take the chill off, but you get no response. You don’t hear the system firing up or feel the radiators or air vents producing any heat. You hope it’s just a quick fix, like a clogged filter or a tripped circuit breaker. On the other hand, you might be wondering if it’s more cost-effective to just have the unit replaced.
Just like running a marathon, we perform better at full strength. If we’re not feeling great, it’s that much harder to finish the race. Similarly, when you set your thermostat to a certain temperature, the system is tasked with maintaining that temperature throughout the room. Working at full strength, the system can easily maintain that temperature (as long as it’s not below 60 degrees or above 80 degrees). However, when injured, the system may struggle to keep the room at your desired temperature. As such, it’s working harder, which means higher utility bills.
If you need a furnace repaired or an air conditioner serviced, we'll send a local technician out to diagnose the specific problem and recommend solutions for you and your family. There will be a diagnostic fee for the visit, and any specific repairs will be an additional charge. If replacing your system is the best solution, the fee for the diagnosis will be credited toward the purchase and install of a new system.
Before selecting the installation location of air conditioner, several main factors need to be considered. First of all, the direction of air flow from the indoor units should not fall on the place of rest or work area. Secondly, there should not be any obstacles on the way of the airflow that might prevent it from covering the space of the premises as much as possible. The outdoor unit must also be located in an open space, otherwise the heat from the house will not be effectively discharged outside and the productivity of the entire system will drop sharply. It is highly advisable to install the air conditioner units in easily accessible places, for further maintenance during operation.
Believe it or not, your HVAC system can affect your health. Because the air is recycled in a contained space, airborne particulates like pet dander, allergens, mold, fungi, cleaning chemicals, and more can become a major issue. We specialize in ensuring the indoor air quality of your Northern Virginia home is of the highest level. To this end, we offer a full line of indoor air quality products and services, including air purifiers, ventilators, humidifiers, UV lamps, and air duct cleaning. Our qualified technicians are trained to ensure your family breathes easily.

Its difficult to describe how good of an experience I had with Cobb heat and AC. Ill put it like this, I have gone two 3 other AC repair companies, they send out their most novice field engineer, they give me a 6000 dollar quote to replace my AC for a property I just purchased, and then they leave. Mr Cobb came out himself, figured out the issue cleaned the condenser coils and told me my unit was only a YEAR OLD!!! He did not try to up-sale me or BS me with a quote to replace the boiler which I have had happen as well as the ac unit. Other AC companies suck, I'm sticking with Cobb. hope that helps
Change the filter: A new filter can cost as little as $20. Since this is the most effective way of maintaining your AC system, there is no reason not to change your filter. Homeowners should change your AC filters whenever it gets dirty. Depending on the filter, you may have to change it once every six months or once every month. Each filter should indicate how long it will last.
The condensed, pressurized, and still usually somewhat hot liquid refrigerant is next routed through an expansion valve (often nothing more than a pinhole in the system's copper tubing) where it undergoes an abrupt reduction in pressure. That pressure reduction results in flash evaporation of a part of the liquid refrigerant, greatly lowering its temperature. The cold refrigerant is then routed through the evaporator. A fan blows the interior warm air (which is to be cooled) across the evaporator, causing the liquid part of the cold refrigerant mixture to evaporate as well, further lowering the temperature. The warm air is therefore cooled and is pumped by an exhaust fan/ blower into the room. To complete the refrigeration cycle, the refrigerant vapor is routed back into the compressor. In order for the process to have any efficiency, the cooling/evaporative portion of the system must be separated by some kind of physical barrier from the heating/condensing portion, and each portion must have its own fan to circulate its own "kind" of air (either the hot air or the cool air).
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.

Not obvious is the fact that they need maintenance routinely, just like any other machine. The filter, usually located behind the front grill, needs to be washed. The condenser coil at the back of the unit can accumulate a lot of debris, and might require a special chemical bath. All air conditioning systems, large or small, need good air flow across the evaporator coil and the condenser coil. Efficiency and performance drop rapidly as air flow decreases. Lose enough air flow and the unit will burn out. Rodents can nest inside when not in use, and can foul up the unit in many ways. Wasps and hornets, as well as the honey bee find finned coils to be comfortable nesting places. Nests and dead insects can ruin the air conditioner.
The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.
The belt should slip right into place. If it seems to be too tight or difficult to set in place, it may be necessary to adjust the motor mount to provide more slack. Then you can re-tighten the tension once the belt is in place. Check the manufacturer’s specifications for proper tension—in most cases, the belt should deflect about an inch when you press down on it.

AC air handler buzzing sounds. Do you hear a buzzing sound when you turn on the thermostat? The only thing that comes on in the house when you turn on the thermostat is the fan relay and fan in the air handler or furnace. Try switching the thermostat HEAT/COOL switch to OFF. Then switch the fan switch from AUTO to ON. The fan (only) should come on. If the air handler makes a buzzing sound, it probably has a bad fan relay or, more likely, blower fan.
In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids (such as alcohol and ether) could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to speed up the evaporation. They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that, soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about 6 mm (1⁄4 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin concluded: "From this experiment one may see the possibility of freezing a man to death on a warm summer's day."[9]
Your HVAC professional can perform a yearly tune-up of your system for around $80-$100. This yearly maintenance can go far toward heading off major repairs to your system, and provide you with peace of mind and considerable savings in the long term. Additionally, regular servicing of your AC unit can help a home inspector to certify that your unit is working properly in the event you decide to sell your home.

This doesn't mean air conditioning isn't right for your home. Some people are more sensitive to heat than others. Even if you can't justify the expense of central air conditioning, window air conditioning units will allow you to cool individual rooms tailored for your needs. If you work from home, you may want to put one of these units in your home office. If you have trouble sleeping with even modestly warm temperatures, you may want to put one in your bedroom. If you love to cook and spend long afternoons using the oven, your kitchen may be the place.
Since the 1980s, manufacturers of HVAC equipment have been making an effort to make the systems they manufacture more efficient. This was originally driven by rising energy costs, and has more recently been driven by increased awareness of environmental issues. Additionally, improvements to the HVAC system efficiency can also help increase occupant health and productivity.[20] In the US, the EPA has imposed tighter restrictions over the years. There are several methods for making HVAC systems more efficient.

Air conditioning units work by using evaporator and condenser coils to remove heat from the air in your home. Warm household air blows through the evaporator coils, which transfer the heat into refrigerant vapor, which is then moved to the condenser in the outdoor part of the unit. The condenser coils turn the now-warm refrigerant vapor into liquid, allowing the heat to be dispersed outside and away from your home.

You should have your air conditioning maintenance done at least once a year, in the spring. Doing it in the spring will allow your technician to repair any damage the unit might have acquired during the winter, and make it ready just in time for the arrival of warmer temperatures. However, it’s best to do maintenance twice a year: in the spring and fall. Sticking to this bi-annual schedule will keep your unit running optimally.
Heating, ventilation, and air conditioning (HVAC) are one of the most important ways to make certain that your Tucker home is a comfortable place to spend time.

In the most general sense, air conditioning can refer to any form of technology that modifies the condition of air (heating, (de-)humidification, cooling, cleaning, ventilation, or air movement). In common usage, though, "air conditioning" refers to systems which cool air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.[3]

AC air handler squealing or grinding noises. Though most air handlers have direct-drive motors, some older units may be belt-driven. Squealing sounds from a belt-drive air handler generally occur when the belt that connects the motor to the blower slips. In most cases, the belt is improperly aligned or worn and needs replacement. Follow the instructions above under Air Conditioner Not Blowing Air and refer to your owner’s manual.


Hii need you guys help! Once my thermostat drop below the set temp , my furnace does not turn on and I was wondering what’s wrong with it. It happens mostly on cold nights. Sometimes I would have to go in the basement and turned the furnace power switch off then on and will come on once I switch it off then on.i also change the thermostat recently, so I don’t think that’s the problem

A mini-split system typically supplies air conditioned and heated air to a single or a few rooms of a building.[38] Multi-zone systems are a common application of ductless systems and allow up to 8 rooms (zones) to be conditioned from a single outdoor unit. Multi-zone systems typically offer a variety of indoor unit styles including wall-mounted, ceiling-mounted, ceiling recessed, and horizontal ducted. Mini-split systems typically produce 9,000 to 36,000 Btu (9,500–38,000 kJ) per hour of cooling. Multi-zone systems provide extended cooling and heating capacity up to 60,000 Btu's.
If your HVAC equipment is more than 10 years old or not keeping your house comfortable, have it evaluated by a professional HVAC contractor. If it is not performing efficiently or needs upgrading, consider replacing it with a unit that has earned the ENERGY STAR. Depending on where you live, replacing your old heating and cooling equipment with ENERGY STAR qualified equipment can cut your annual energy bill by more than $115. But before you invest in a new HVAC system, make sure that you have addressed the big air leaks in your house and the duct system. Sometimes, these are the real sources of problems rather than your HVAC equipment.
The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

In the United States, HVAC engineers generally are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), EPA Universal CFC certified (for installation and service of CFC HVAC devices), or locally engineer certified such as a Special to Chief Boilers License issued by the state or, in some jurisdictions, the city. ASHRAE is an international technical society for all individuals and organizations interested in HVAC. The Society, organized into regions, chapters, and student branches, allows exchange of HVAC knowledge and experiences for the benefit of the field's practitioners and the public. ASHRAE provides many opportunities to participate in the development of new knowledge via, for example, research and its many technical committees. These committees typically meet twice per year at the ASHRAE Annual and Winter Meetings. A popular product show, the AHR Expo, is held in conjunction with each winter meeting. The Society has approximately 50,000 members and has headquarters in Atlanta, Georgia.

It can be hard to make the decision to replace or repair your AC unit. However, in many cases, homeowners call in HVAC professionals to check their units and provide a second opinion. A technician can tell you if there’s plenty of life left in your old air conditioning unit or that it’s time to let it go and get a new one. Your HVAC technician may check out your home’s insulation quality, too. You could increase your system’s effectiveness by improving the insulation.

If your furnace needs to be repaired, you’ll want to find a qualified heating, ventilating and air conditioning (HVAC) repair technician. Each state has its own licensing requirements; some require all HVAC technicians to have an HVAC license, while others only require someone operating an HVAC service and installation company with employees to hold a contractor’s license. For example, in Alabama, the Alabama Board of Heating Air Conditioning, and Refrigeration Contractors regulates licensing, while in Kansas there is no state regulatory body and HVAC licensing can vary by region. For simple furnace repairs like changing out a filter, a trusted handyman can probably handle the job, but a trained professional should be hired for tasks like replacing a gas valve, installing a new inducer fan motor or other critical furnace repair jobs that involve dealing with gas leaks or other dangerous conditions.
