How Does an Air Conditioner Really Affect Your Monthly Energy Bill?

Air Conditioning Units Energy Efficiency

Many people have the misconception that an AC typically uses less electricity than a common electric heater. However, this isn’t always true, especially for larger units designed to cover a room or an area of greater square footage. Air conditioning is costly, especially in warmer areas and where the insulation of the building doesn’t help you too much. So it’s a good idea to have a clear picture of how much your AC will cost you before you consider purchasing a new unit or turning on your old one to heat your home or building on a regular basis.


If you’re using a central Denver air conditioning system, the average consumption you can expect per day will be somewhere between 3,000 and 5,000 watts. This usually depends on the size of the area you want to heat – with the larger value being assigned to a larger square footage.


To calculate how much you have to pay for that, let’s say you use your AC about 3 hours a day on average. At a price of $0.15 per kWh, you can expect about $47 per month or $570 per year. Of course in places like Hawaii, where electricity is more expensive, that amount can even be double.


Remember that this is just the amount you’d pay to run your AC for 3 hours per day. If there’s a heat wave and you have to run it more extensively, you can expect to pay even more. So make sure you are fully aware from the start of the type and size of AC you can afford and the number of hours you can afford to run it each day.

The Main Questions You Need to Ask About Your Air Conditioner

Main questions air conditioning

Regardless of the type of HVAC or standalone air conditioning system you own, it is essential to ask as many relevant questions as you can, so you’ll know exactly how to operate and maintain them in good shape, if you want to avoid having to call in the experts for a repair job too often.


One of the first things to ask about is how large the system should be for providing the adequate air conditioning power to a room, an apartment or a house of a specific square footage. Asking your contractor about these details will provide you with the ideal information to purchase the right size system, so you don’t have to overwork it and you won’t run the risk of feeling hot in the summer despite running your AC on a constant basis.


How long will installing a new system take? Would it be a viable solution to just repair the old one? When it comes to fixing your AC, you might want to check and see whether it’s even worth it, or whether it would be best to just get a brand new AC with all the bells and whistles.


How often should you clean or replace the filters? Do you have to clean the vents? What other maintenance tasks can you do without the assistance of a team of experts? In many cases, you’ll find the right answers to these and many other maintenance-related questions by simply calling on your local contractor at

Important Things to Do Before Turning on Your AC for the Summer

First Things First Important Air Conditioner Tips

When considering the maintenance required by a working AC system, as well as the tasks you have to consider around the house, you’ll find that there’s a lot to do prior to turning on your AC for the summer. There are vents to look after, windows to seal and a whole number of other things that will require your attention:


  1. Start by making sure that your AC is working properly. You can check the filters and vents yourself, or have a professional take a look at them. Also, simple tasks like cleaning the vents can be performed by you or another member of your household, and you won’t need professional air conditioner Denver technician support to deal with those.
  2. Test your AC, and make sure it operates at peak efficiency. Check for strange noises that could betray a mechanical problem. You can also check to see how much electricity it uses by turning off all other electrical and electronic devices around the house and checking the electric counter. That way, you’ll have a clear picture of whether the AC is as efficient as advertised or whether something is causing it to operate at a lower level of energy efficiency.
  3. Seal your windows. If there are cracks or you have older windows that don’t close up properly and can no longer be repaired, consider buying replacement windows in all the rooms where you’ll be using your AC.

Why Annual Maintenance to Keep Your HVAC Going Is Worth the Money

Annual HVAC Maintenance AC Repair Recommended

If you ask any expert, the yearly maintenance for most types of HVAC units is a pretty big deal. Not only is the risk quite pronounced if you avoid annual maintenance, but most units will also operate less efficiently as time goes by and use up a greater amount of fuel or energy.  Having Denver AC repair done in early Spring is recommended, as well as furnace repair in early Fall.


It doesn’t necessarily matter what type of HVAC you own, since some tasks, like cleaning the ducts, will be required every year regardless. When the ducts gather too much dust and dirt, the transfer of heat no longer works properly, and no matter how powerful or efficient your unit might be, it will still need to produce more heat to get the job done.


The biggest reason why annual maintenance is needed is to avoid the risk that the unit might break down completely when you need it the most. This usually happens in harsh winter conditions, when the HVAC has been working overtime for quite some time.


There were many cases in the past when homeowners wanted to save a few dollars by avoiding maintenance, and they ended up having to pay a much greater amount on HVAC repairs – not to mention that they’ve also exposed themselves to the cold for at least a day or two, before the unit was brought back online. To avoid all that, it’s definitely worth paying for annual maintenance.

How Frequently Should You Use Your Air Conditioner to Cool Your House?

Although some people might prefer to use the air conditioner on a constant basis, especially in very warm areas, this isn’t usually recommended and causes a need for Denver AC repair more frequently. Doing so will not only put added pressure on the system and cause it to malfunction sooner, but it could also cause health problems when your body is adapted to the cooler environment and then you suddenly have to go out and do some physical work.


The best way to use your AC is intermittently, by turning it on and off occasionally to cool the air and then maintaining the cold by insulating your room in various ways – such as shutting all doors and windows, setting up blinds to keep the sunlight out, and so on.


The answer to the question of how often you should turn on your air conditioning and how long you should keep your AC on depends on how large and strong your unit is. If it’s oversized for the room you own, then it will probably only need to run for about 10 minutes at a time, a couple of times per hour. If it’s just the right size, however, it will likely need to run about 15 minutes at a time.


Of course, many other factors come into this as well, including how well your insulation is working and how quickly the temperature and weather conditions tend to change in your area.

What Your Heating and Cooling System Is Trying to Tell You

Heating And AC System Repair

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.

How Do Air Conditioners Work?

How Does An Air Conditioner Work

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.


Tips For Cooling Your Home Faster During The Summer

HVAC Cooling Home

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.  See more on cooling your home at

Tips for Keeping Your House Cool During Summer

Air Conditioning Is Necessary To Combat The Summer HeatSummers 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.
