The thermostat is the brain of your HVAC system. It measures and monitors ambient indoor climate, telling Kemnitz when air conditioning and heating units have to work whenever the temperature goes above or below the threshold.
Summer is in full swing, and the last thing you need is for your AC to breakdown. The air conditioning system has had a long break during winter. In most cases, it has not been fired up. This means that an HVAC tune-up is required to ensure the system is in tip top shape.
One of the most frustrating feelings is turning on the HVAC during a hot day only to discover that it is not working. Therefore, it is very crucial to contact a Mission Viejo expert that can check your system and get it ready for summer with an HVAC tune-up. It ensures that your home is ready to have fun in summer without any surprises.
Identifying Issues with Your AC
Note that during summer, most technicians are usually busy with unending repair calls. Therefore, it is wise to get ready before summer so that the system can be up and running when others are desperately searching for the available technicians. If you haven’t scheduled your routine maintenance yet, don’t worry. Here are some things you can check yourself in case all technicians in your area are busy.
Self-inspection checklist for Mission Viejo homeowners
- Different, unfamiliar odors that emanate from the AC
- The system blows up warm air instead of the refreshingly cooler air
- Fluid leaks around the AC
- The system may fail to start or other times running regularly
- Being unresponsive to any temperature alteration
- Strange sounds such as grinding might be an indicator of a fault in the system
What to Expect During an HVAC Tune-Up Visit
A professional HVAC technician can be able to diagnose the fault and advice on the best course of action. During the maintenance visit, the expert usually does the following to ensure that the system is in good condition.
- Cleaning of all the filters which ensure that the AC does not blow the dust trapped on the filters together with the cold air.
- Inspection of any fluid leaks which involves the use of a dye test to detect any fluid leak that might be difficult to identify.
- Visually inspect all the components of the system. Summarily, this gives the technician a chance to tighten any loose connections and fittings.
- Inspection of the working condition of the thermostat which goes with the checking of the refrigerant pressure and level.
- All the moving parts get lubrication for improved efficiency.
After a comprehensive checkup, the technician provides a list of all the components inspected. At this stage, you can note what needs a replacement as the summer heat continues to test your unit.
Benefits of an HVAC Tune-Up
Tuning up the heating and air conditioning system before summer is not only crucial but also necessary due to its numerous benefits. Having a system run for some days only to realize that it is not properly working translates into loss and high energy bills. As stated earlier, most technicians are usually busy in summer. Therefore, the cost of getting a specialist in summer is greater than in spring.
A well-maintained system will last longer than a system that was less effectively maintained. Therefore, a pre or mid-summer HVAC tune-up is necessary to save on costs and energy.

The heating and air conditioning industry constantly looks to improve home energy efficiency. Variable speed technology helps homeowners maximize their indoor air experiences. Compared to single-stage and two-stage motors, variable speed technology improves the efficiency of all air conditioners.
What is Variable Speed Technology?
Variable speed technology affects the fan and blower within an air conditioner. Single-stage motors only have “on” and “off” fan settings. Two-stage motors have an intermittent setting for reduced airflow and a wide-open setting. However, variable speed motors provide more control settings, operating between 40% and 100% capacity.
You probably have experienced the abrupt cycles of a single-stage motor. When the air conditioner detects a temperature change, it will run on high until the thermostat registers an adequate temperature drop. Throughout the day, you may feel the room temperature cycle between cold, comfortable, and too warm. A single-stage motor only can turn “on” at maximum capacity and then turn “off.”
A variable speed motor, in contrast, provides the amount of airflow needed to maintain a comfortable temperature. The motor can subtly maintain a comfortable temperature without using its maximum capacity. Therefore, the motor only uses the amount of energy needed at a given time.
Benefits of Variable Speed Technology
Variable speed motors cost slightly more than single-stage or two-stage motors but also offer many benefits that make them more appealing to modern homeowners. Consider some of the reasons why variable speed technology is gaining popularity:
- Efficiency. Since the technology only uses the amount of energy needed at a given time, it does not waste energy like other types of technology. Operational efficiency delivers homeowners two beneficial outcomes: energy expense savings and environmental sustainability.
- Comfortable temperatures. Instead of cycling through various stages of cooling, a variable speed motor will keep a home hovering around the ideal temperature throughout the day.
- Air quality. Variable speed motors tend to run more often at a reduced capacity setting than other types of air conditioners. When the air conditioner runs, it filters and circulates air. With a variable speed unit, you may need to change your air filter more often, but you can breathe easier knowing the system traps higher levels of allergens and contaminants.
- Zoning technology. Zoned AC systems allow for customized air control in different spaces. For instance, if your back bedroom gets hot more often than other rooms, a zoned system will adjust airflow in that one zone for improved comfort. With variable speed technology, a zoned system can effectively manage temperatures in different spaces to suit your needs and energy concerns.
- Humidity control. Working consistently allows variable speed motors to consistently pull moisture out of the air for improved humidity levels. Lowering humidity levels inside the home can improve overall comfort without changing the thermostat temperature.
Like a smart thermostat, variable speed technology can make subtle, efficient, and comfort-enhancing changes on a daily basis. Any homeowner looking for improved air conditioning may enjoy the benefits of variable speed technology. For more information, contact Kemnitz today.
Excessive humidity can not only make one feel hot during the summer, but also affects the performance of HVAC systems. It takes more energy to achieve optimal indoor temperature when the humidity is too low or high. Modern units come with dehumidifiers and humidifiers to regulate the humidity level.
Effects of Humidity on Air Conditioning
Air Conditioners work by removing excess moisture and heat from the air. If the level of humidity is too high, the unit is forced to work harder. Common symptoms of high humidity include moist air that produces a clammy feel on one’s skin, foggy windows and an unpleasant odor. Units without sufficient cooling capacity find it hard to cope with extreme humidity. As a result, the home never feels comfortable for the inhabitants.
HVAC Systems and Cooling Capacity
A common misconception is that large, powerful units cool homes more effectively. In such cases, the system is usually unable to effectively remove moisture. Because the unit doesn’t run often, it doesn’t get the chance to remove the moisture that’s in the air. This means that the humidity level in your home remains high. It’s therefore vital for one to purchase an AC system that suits their home.
A dehumidifier would be the best option for dealing with excess humidity. When installed on a HVAC system, this appliance pulls moisture from the air before it gets into the house. It’s therefore possible to adjust both the temperature and humidity level simultaneously. Keeping the humidity levels in check means that ACs run more effectively.
Humidity and Heating
During the winter, humidity levels drop significantly. This makes a home feel much cooler than it really is. The heat pump/furnace is thus forced to work harder to maintain a comfortable temperature within the house. If humidity levels fall below 50%, the ideal thermostat range of between 71 and 77 degrees doesn’t produce comfortable results. The apparent temperature within the home usually feels too low.
To deal with low humidity, you need to install a humidifier to the HVAC system. This moisturizes the air before it enters a house. The home’s relative humidity is maintained above 50%, which makes the apparent temperature feel warmer. This results in a more comfortable home and increased efficiency.
Gas furnaces are very easy to operate but they do require regular care and maintenance. Proper maintenance can reduce furnace repairs, maintenance costs, energy expenditure and spotty heating in your home. To catch any problems with the system, you should consider starting a furnace well ahead of winter for a test run. Any incipient problems like leaks, tears and blocked ducts will be visible immediately and can be repaired at once. As gas furnaces are simple to use, you can also evaluate the system yourself for damages by carrying out a thorough heating system inspection.
Inspection and tuneup of your heating system: Here is what you can start with.
Shut down the system — Before starting any type of maintenance, make sure you turn off any electrical or gas connections for the furnace. All furnaces usually have a distinctive red switch that is located near the burner, near the fuel shutoff valve or the incoming gas pipe.
Clean the combustion chamber — Gas and air mix in the combustion chamber to produce heat required for the entire home. As a result, the combustion chamber is going to be filled with soot that will build up over time. If possible, let the chamber cool, then scrape out the soot with an industrial grade vacuum, and replace the cover.
Check the flue pipe — Gas furnaces have a flue pipe that vents CO outside the house. Over time, the metal pipe may develop holes that will leak CO into the house causing serious health problems. Small holes are patched with plumbing tape but badly rusted pipes need to be replaced completely. You should also check the flue pipe’s barometric damper that will then regulate the air entering into the chimney to heat the home.
Check and change the air filter — Ideally, air filters have to be changed every three months. During the winter, we recommend checking and changing the filters every month. This is because you and your family are breathing in air that comes only through the filter. This is easy but some filters are permanent and they have to be removed, washed, dried and then reinserted before the furnace can be turned on.
Adjust the heat — Gas furnaces need to be analyzed with a combustion analyzer to measure heating efficiency. Along with heating efficiency, it is also necessary to clean the fuel nozzle and then inspect the color and shape of the flame.
Check all vents and ducts — Vents and ducts may be clogged with dirt and debris. Floor vents in particular have to be cleaned out or vacuumed clean. Checking the ducting system is also a good way to locate leaks and blockages. We also recommend you check grills and make sure that they are free of blockages.
The bottom line
Regular inspection and tune-up of your heating system is essential but most homeowners do not really have the time and patience. As a result, it is a good idea to hire a professional contractor or firm to do the job. Contractors can be called in for a one-time visit or they may offer annual contracts. Annual contracts are the best, as the contract will involve yearlong testing of your heating and cooling systems, repairs, maintenance and cleaning of the entire home ventilation system for a set contract price. Not only is this affordable but it is a very sensible option for ensuring a warm home during the long winter months.
While some people are able to repair a clogged drain or a blown fuse, the prospect of commercial HVAC equipment repairs is usually well over the head of even the most handy of handymen. Companies that specialize in trouble shooting HVAC electrical and mechanical problems, however, usually only need to take care of a few issues, since the most common HVAC concerns can be solved relatively quickly. Here are some of the common troubleshooting issues that concern repairs and commercial HVAC replacement.
In the same sense that you need to change the filter of a car engine, a fish tank, or a coffee machine, you also need to change the filters of a commercial HVAC whenever it gets cluttered with dust and detritus. When a filter becomes too clogged up with dirt, it will have to work much harder in order to pump air through the filter, which results in overloads and power failures. In the event that a minimum of air is moving over the coils of the HVAC, furthermore, it will not move the cold air out fast enough, which results in a buildup of ice over the entire coil — effectively choking the unit into failure. So, an HVAC filter should be changed every month.
The electricity that flows into a commercial HVAC is just like that which powers any other appliance: when it fails or shorts, it will be unable to run the machine. A fuse exists to ensure that a shortage does not damage the mechanical unit, but a fuse is designed to fail and thus will break down in a matter of time. It can often be easy to tell when a fuse is blown since there will be flash marks from the power around its switch.
The massive amount of air that a commercial HVAC takes in and blows out would move a large quantity of dust around both inside and outside the machine. The evaporator coil on the machine can and will get dirty whenever too much dust accumulates. Since you cannot wipe down the coil, lest you risk damaging the unit, commercial HVAC equipment repairs require sensitive vacuuming. These vacuums will eliminate the objects that cause the coil to heat up: whenever it the programming zone controls read that the unit cannot cool air to at least twenty degrees colder than the exterior temperature, it suggests the coil is too dirty.

Many people, especially those in older homes, use window mounted air conditioning system. These appliances are great for cooling down your home fairly inexpensively. As with all other appliances, these units do require regular maintenance and upkeep to ensure that they continue working at an optimal level. Doing so will help your unit to properly cool down your home with maximum efficiency and ensure the air used to do so is clean for you and your family.
Determining the Correct Size
The first thing that needs to be considered when covering maintenance of a window mounted AC unit is the size of the unit itself. In most scenarios, consumers tend to think that bigger equals better. However, a window unit that is too big for the room it is intended to cool will not perform at its highest level. This is because the too-big unit will not properly reduce the humidity level of the room, prohibiting it from running efficiently.
Regularly cleaning the window unit, especially after sitting unused during the winter months, is extremely important. This can easily be done by unplugging the unit and removing it from its mounting frame. Once this is done, you can vacuum the the outside of the unit and its coils with a vacuum attachment. If you prefer, you can even hose down the coils, careful not to get the electronics or motor wet. Next, you want to check the coil for bent cooling fins and the air filter for any damage. A coil fin comb can be used to help straighten any bent fins. If the filter is damaged, you will want to replace it. If it is dirty, you should wash it with soap and water and let it dry thoroughly before replacing. Once this is done, you can put the window unit securely back in place and use it.
Changing the Air Filter and Dusting
While this thorough cleaning is really important for the maintenance of your window mounted air conditioning unit, you should also remember to periodically dust and clean around the unit. It is a good idea to simply incorporate this into your dusting routine. This will prevent the unit’s vents from getting clogged with dust and pollen. In turn, your unit will properly cool your home while keeping your cost of doing this low. It is also crucial that you remember to clean or replace the air filter every 2 to 3 weeks, especially if the pollen in your area has been particular bad or if you have pets.
Upgrading Thermostats and Units
In addition to choosing the correct size and regularly cleaning your window unit, there are a few more things you can do that are beneficial. If you have a newer model, you may have a programmable timer on it. This will help you control when it turns on and shuts off, helping you control your costs. If you have an older unit, it may be advisable to consider trading it in for a newer, energy efficient model.
If you follow all of these tips to maintain your window mounted air conditioning system, you are sure to enjoy the benefits of a nice, cool home without breaking the bank.

Geothermal is a hot topic in the green movement today. Both professionals and homeowners are starting to really take an interest in learning about geothermal cooling and heating technology. However, despite all the new found interest, it really is not a newer technology. In fact, it has been around for decades and has improved significantly. Currently, in the United States alone, over a million geothermal units have been installed in both commercial and residential applications.
How it Works
This type of system works by using the heat that is stored below from the ground surface, and is mostly considered solar energy because the earth does get heated up by the sun, and provides cooling, heating and hot water assistance.
In the heating mode, the ground absorbs the heat and it then gets pumped into your residence. In the earth loop is water circulating which is cooler than the ground surrounding. Because of this, the water absorbs energy, from the earth in a form of heat. Then this energy is carried by the water and pumped into the heat exchanger pump. When in the heat exchanger, the water’s heat energy is absorbed by the refrigerant. Then the water becomes a colder temperature as it leaves the heat exchanger, and circulates and picks up more energy from the earth loop.
The refrigerant gas that is filled with the earth loop energy travels to the compressor from the heat exchanger. The temperature of the refrigerant in the compressor rises to 160 degrees. The heated refrigerant then makes its way to the air heat exchanger. At this point, air is circulated across the air coil by the heat pump’s blower, which then increases the air temperature and is then blown through the ductwork heating the home. Once heat energy is released into the air by the refrigerant, it starts the same cycle all over again.
In cooling mode, heat is pumped from your residence and releases in the ground. The earth loop water circulation is warmer than the ground surrounding. This results in energy being released from the water, in heat form, into the earth. Hot refrigerant gas that comes from the compressor in the heat exchanger transmits heat into the water. This results in an increase of water temperature, and heat is released into the ground.
Heat energy is released from the refrigerant causing it to become a cool liquid and this liquid begins to travel to the heat exchanger. At this point, warm, humid air is circulated from the heat pump’s blower, and flows across the cool air coil. The home is then cooled from the air being blown from the ductwork. The air coil refrigerant absorbs heat energy from the air, and flows into the compressor. Once this refrigerant is released from the compressor, it starts the whole cycle again in the earth loop heat exchanger.
Geothermal heat pumps are comfortable, durable, safe for the environment, clean and non-allergenic. These pumps require minimal maintenance, and they lower your cooling and heating bills significantly. They provide a great deal of comfort by cooling and heating evenly and getting rid of cold and hot spots. They minimize threats to the environment, since they burn fossil fuels.

No matter how good your air conditioning system is, it is going to end up experiencing problems and faults from time to time. You will therefore need to keep an eye out for these. There are a couple of problems that are quite common and can often be avoided by simply making sure that you maintain your system properly. Some of these issues are also quite easy to sort out yourself, while others are going to require the assistance of a professional.
If you do decide to call on a professional, then it is a good idea for you to make sure that you find someone who is properly qualified. If you go with a company you are not normally going to have to worry as they are likely to be certified. If you decide to take the services of a private contractor, however, do not be afraid to ask them for proof of qualification. They should be more than happy to provide it for you.
Below are a couple of issues that can happen from time to time:
Dirty Air Filters
The air filter is a very important part of your system, as it makes sure that no dust and debris actually gets into the air conditioner or causes extra problems. Most people are going to change the system’s filter regularly to ensure that everything is running properly. You may also find that all you need to do is clean the filter from time to time.
If the filter gets clogged up, then it is going to restrict the flow of air into the system. This is going to provide you with a less than satisfactory level of air conditioning, and it can make your home very uncomfortable during the hot summer days.
Dirty Condenser Coils
Condenser coils need to be clean, but many people may forget about them. They are often the cause of a lot of issues that air conditioners will have during the summer time. Condenser coils are going to draw the heat out of your home, and therefore they are going to be situated on the outside part of the air conditioning unit.
Dirty condenser coils can end up bringing the efficiency of your system down. When this happens, you are going to end up spending more energy on a less effective form of air conditioning. This is something that you will need to try and avoid by keeping your coils clean.
Environmental damage is often common in the form of things like thunderstorms. The key here is to make sure that you avoid electrical issues from taking place by switching off the air conditioner when the thunderstorm passes overhead. This is one of the safest things to do, as you will be able to ensure that your system does not get damaged.
Overall, it is important to keep an eye on your systems to make sure that they do not break down during the summer. This will ensure that your home is more comfortable.
