Heating and cooling systems work hard to maintain the temperature in your home at comfortable levels and all that strain can eventually cause system components to malfunction. Here are some of the most common signs that indicate some sort of fault:
- Strange noises – clicking, chattering or thumping noises coming from the HVAC call for immediate attention. Whining and sqealing signs coming from the motor indicate worn bearings, while dirty burners may also make strange sounds;
- The cooling or the heating function or the fan won’t turn on or off – this sign usually tells you that there is a problem with the thermostat and need of repair by a Denver AC repair company;
- Inefficient operation and a strange smell – the most likely cause of the issue is a clogged, dirty or worn filter that needs to be replaced immediately;
- Diminished overall performance and hiking energy bills – one of the most common causes behind the problem is aging. HVAC systems include lots of components that can be affected by normal wear and tear, but that continue to work to a certain extent even when they are approaching the end of their lifespan. The replacement of the affected components usually restores the efficiency of the system and will reduce energy bills as well.
Energy-related expenses make about half of monthly household expenses. While heating is something that you cannot live without in winter and cooling is also essential if you want to maintain the comfort of your home, each year has several months when you can cut back on heating and cooling bills:
- The end of spring – when temperatures reach comfortable levels and those comfy temperatures are maintained, too, it is time to turn off or to turn down your heaters. Try to use the heaters only when it gets really cold – compensate for the lower interior temperatures wearing warm clothes, don’t worry, summer will be here soon with hot days;
- The end of summer – the end of the summer, when the heat subsides, is the next period when you can reduce your energy bills. Turn your air conditioner down or off when you don’t need cooling that much or at least reduce the amount of time when your AC is running. On hot days, try to use other cooling methods, such as closing the blinds or the shutters. You can also use the lower night-time temperatures to your advantage, keeping the windows open at night and closing them for the day to keep cooler air in. End of summer is also a great time to have a professional air conditioning repair Denver technician do a complete inspection and repair.
The operating principle of air conditioners is similar for all these appliances, including refrigeration units, heat pumps etc. and is based on the temperature exchange between two different environments with the help of specially formulated liquids, generically called refrigerants.
From the beginning, it is necessary to specify that there is no air exchange between the indoor unit and the outdoor unit of an air conditioner, and the cold air inside does not come from outside via the connection between the two units of the equipment. Inside, hot air is circulated continuously and cooled by getting it in contact with the refrigerant that is found in the air conditioning equipment, thus forming a continuous heat takeover and heat removal circuit.
Processes that happen in the indoor unit of an air conditioner
Due to the fan’s rotation movement, the warm air in the room is filtered and driven on the evaporator located inside the unit, through which circulates the refrigerant. There is a temperature exchange: the hot air cools down in contact with the evaporator pipes and, it is released back into the room and the heat is transferred to the refrigerant. As the refrigerant takes over the heat, it switches from the cold liquid state to the low-pressure cold gas.
The cooling process make water vapors condensate; the water resulted is being collected in a special tray released externally, through a hose. If your AC in not working as it should be, it might be time to have an air conditioner Denver technician do some repairs.
Besides using air conditioning, there are other more economical solutions to protect your home from excessive heat.
Tip 1: Avoid the sun’s rays. To protect the interior against summer`s heat, you must keep sunlight away from your windows. To do this, you can use blinds or window shutters. Let them down in the morning, so that the interior of the building does not heat up. If you live in a warm area, with lots of sunlight year round, you should also consider installing a reflective roof.
Tip 2: Ventilate your home efficiently. It is advisable to open the windows only after sunset, at night and early in the morning, to cool the rooms. It is best to use cross-ventilation with windows and doors that are completely open. However, the most efficient is ventilation through intelligent ventilation equipment, which evacuates very quietly the indoor air from the house and constantly supplies filtered, fresh air.
Tip 3: Keep moisture at an optimum level. An additional condition for a enjoying adequate thermal comfort is maintaining the optimal air humidity. During the hot summer days, humidity must be as low as possible. If the level of humidity rises too much, the body is sweating, and high temperatures are more difficult to bear.

Summers are becoming hotter and more humid each year, prompting homeowners who don’t want to pay excessively high cooling bills to introduce supplementary measures to keep their homes cool without running their air conditioners high all the time. Fortunately, most of these measures are easy to implement – here are some tips for you:
- Use your drapes and shutters – blocking the access of the sun’s rays can reduce your interior temperatures significantly. Air your home during the night, when the air is cool and draw your drapes, blinds and shutters during the day to preserve the cool temperatures. While airing your home, open windows at both ends of the house to allow air to move through your rooms;
- Turn off the lights in the rooms that you are not using – light bulbs, even modern, energy-saving ones, emit heat when they are turned on. If you pay attention to turn off the lights when you leave a room, you can save on your lighting-related and on your heating-related expenses as well;
- Don’t cook inside – use your outdoor grill or stove for cooking instead of the appliance in the kitchen – it is a great way to add new meals to your list of recipes as well as to keep the temperatures low in the building.
In most cases, it’s best to have a professional air conditioner Denver technician do this annually, for use in the extremely hot days.
HVAC maintenance is essential not only for the health of the HVAC unit, but also for the health of the people using the room served by the unit – without proper maintenance, HVAC systems can let contaminants, such as allergens and viruses, spread in the air, the capacity of the unit will decrease or, even worse, the unit will fail prematurely, making you pay a lot for the repairs. Here are some more details about you can save money with HVAC maintenance:
- Reduced repair costs – properly maintained systems don’t break down as often and the faults are not as costly to repair as in the case of neglected HVAC systems. In most cases, the complete failure of the HVAC system is very costly to remedy and such faults always happen at the most inconvenient times, so they are best avoided;
- Longer life for the system – maintenance can efficiently prolong the life and the problem-free operation of your HVAC system;
- Lower energy bills – your HVAC will probably be able to cool and to heat your rooms to the desired temperature for a long time even without maintenance, but unmaintained systems work much harder to deliver proper performance than regularly cleaned and maintained ones, which also means that an unmaintained HVAC system needs much more energy that one that has been taken proper care of.

Spring maintenance is for your air conditioner what spring cleaning is for your house: the process of assessing the impact of the winter and of preparing the unit for flawless operation when it is needed the most. While you can hire a professional air conditioning repair Denver technician to inspect and maintain the more complex components of your HVAC system, there are a lot of things that you can do by yourself – here are some:
- Cleaning the outdoor condenser unit and the area around it – make sure there is at least 18 inches of clearance around the condenser unit and clean the unit itself, too, using a bucket of warm water and some mild detergent. The process is essential not only for ensuring safe and efficient operation, but also for revealing faults, such as cracks and leaks;
- Replace or clean the air filters – some units use disposable filters, others have permanent filters that can be cleaned under the tap. The filters play the role of maintaining healthy air quality in your rooms, so maintenance is essential when it comes your HVAC filters. Locate all the filters in your unit using the equipment’s manual, then handle the filters as described in the instructions – replace disposable ones and clean the permanent ones.
Air conditioning is more and more popular and accessible, but there are still people who are afraid of it because they think they may experience health problems later on, especially related to the respiratory system, or, if they already have such health problems, they believe they will get worse.
However, if the choice of the air conditioner is correct and the appliance is maintained and cleaned regularly, nobody should experience health issues when using it. So, if you have an air conditioner at home, you must not worry about how often you should use it. You and your family will be safe if you only keep those filters clean and change the air direction to avoid being exactly in its way. The air flow must not be directed to people in the room, because some of them are more sensible and might experience neuralgia, neck pain and torticollis (numbness in the arms or fingers). It is preferable that the distance between the air conditioner and a person is of at least 5 meters, and the air filters are cleaned twice a year, Denver AC repair services are affordable and well worth the investment.
If you are unsure about purchasing such an appliance for your home, we can tell you for sure that unless you have a contraindication from your doctor, then you can buy an air conditioner and use it whenever you want.
Air conditioners that are composed of a wall-mounted unit, hoses and cables and an outdoor unit need regular cleaning to ensure proper functioning and operation that does not put the health of those in the building served by the air conditioner at risk. While interior units usually do not draw in any large debris and the cleaning of the component is fairly easy, requiring only filter replacement and cleaning with some special products, the outdoor unit is permanently exposed to the elements, therefore the cleaning process in its case is somewhat more complicated. Here is how to ensure that the outdoor unit of your air conditioner stays debris free r:
- Regular checks – checking whether the unit is free from leaves, twigs, other plant particles, feathers, dust, small stones and other debris is very important, especially if the unit is surrounded by vegetation;
- Cover the unit when you mow the lawn around it or if you do any work that might send debris into the outdoor AC unit;
- Trim the shrubs, bushes and tree branches that might clog the outdoor unit;
- Dismantle the unit twice a year or whenever you deem it necessary and perform a thorough cleaning of the components, including the case and the fans;
- Keep the unit covered when it is not in use during the colder months, and have an air conditioning repair technician out in Spring.
A lot of people think that ignoring air duct cleaning tasks is not that bad. After all, if the HVAC or AC unit is still working, why would you want to spend a lot of money on a service just so they can tell you that and perform a task that seems so useless? Unfortunately, things are never as “black and white” as all that.
You don’t always know when your furnace or AC unit will stop functioning, and unfortunately, one of the many factors that could lead to its demise is that of having dirty air ducts. If the air ducts that circulate the air throughout your home are dirty, then it stands to reason that the machine will have to pump air a lot harder to get to the desired results.
Since modern day HVAC systems regulate their output automatically based on how abrupt the temperature change may be, it stands to reason that a dirty air duct will cause them to use up more energy and fuel, and ultimately put the entire system under tremendous strain.
The answer is to clean your air ducts regularly. You should definitely consider it as part of your annual maintenance plan, and definitely do it at least twice a year (once before winter and once before summer), in order to make sure you can extend the life span of your furnace and AC as much as possible. Consult a heating and air conditioner Denver professional to set up a maintenance schedule.
