How often to change your air filters can depend on [several factors|a few things|the following]1]: the type of air filter you are using the overall indoor air quality how many pets are in the home the number of people occupying the home, and the level of air pollution and construction around the home For basic 1″-3″ air filters, manufacturers usually [say|recommend|direct you]2] to change them every 30-60 days. If you suffer from light to moderate allergies, you could upgrade the air filter or change them [even more often|more frequently|every few weeks]3]. Or, if you’re in a more remote area or less occupied home (like a vacation home) and there are fewer cars around, annually may be [quite sufficient|adequate|often enough]4]. Here are [some general guidelines to|common rules to help you|averages that might help you]5] know how often you should change the air filter at home: Vacation home or single occupant and no pets or allergies: every 6-12 months “Average” suburban home without pets: every 90 days Add a dog or cat: every 60 days Add more than one pet or anyone has allergies: 20-45 days
This task is more accurately carried out by one of our qualified engineers; however, there are ‘rule of thumb’ guides to calculating heat-loads in residential applications. The size of the room, number of occupants, ambient temperature and the electronics heat loads are the factors which determine the size of the unit to be installed. Can the equipment heat as well as cool? It certainly can, and very efficiently too. The systems that heat as well as cool are referred to as ‘heat-pump’ systems. These systems are fitted with additional valves within the outdoor unit that can reverse the flow of the refrigerant cycle. In effect, the system then tries to cool the outside air, and rejects the heat which is collected (and amplified) to inside. The rated heating capacity of a ‘heat-pump’ system is generally slightly higher than its rated cooling capacity, and provides a huge saving in electrical consumption over any other form of electric heating. An electric fire, heater or under floor heating system that has a rated heating capacity of 3 kW, consumes a directly proportional 3 kW of electrical power. Some of the latest energy-efficient ‘inverter’ heat-pump systems can produce more than 5 kW of heat from 1 kW of electrical power, in turn providing an electrical saving of more than 80%.
No. One of the most important design criteria for the equipment manufacturers is a low operating noise level. Many systems incorporate ‘quiet’ or ‘silent’ modes, which provide sound levels as low as 20 dB (A) from the indoor unit and 43 dB (A) from the outdoor unit. In basic terms, you have to be within 2 meters of these units in the quietest of environments, to hear any indication that they are running. How long does it take to install? This is dependent on the type of equipment selected and the complexity of the installation. A rough ‘rule of thumb’ would be, for a residential setting, with one lounge machine and two bedrooms, the installation would be complete in one day or two.
As the name suggests, air-conditioning services in kenya is the process of conditioning (altering) the air within a chosen environment. The term ‘conditioning’ can refer to the control of the temperature, humidity or cleanliness of the air, in order to achieve desired conditions.
Certain commercial processes require some very specific conditions to be maintained, however in the home we simply need to achieve a general level of comfort for the occupants.
In today’s fast paced home and business environment, the quality of air that you breathe in, needs to be taken very seriously. Breathing in good quality air at home or in the workplace not only reduces the risks of health hazards but also encourages productivity. This is exactly where the HVAC systems come into play. They warm or cool the air as per the requirements and also supply clean air which is so important for good health. Apart from regulating the temperature of the building, the HVAC systems help to keep your body warm and comfortable.
Going green global trend has seen an increase in demand for AC and refrigeration systems that are extremely energy efficient, cost effective and environmental conscious. Today’s designs are able to accommodate the heating as well as the cooling components in a single unit. This has enabled them to use energy in a more cost effective manner thereby reducing electricity bills to a great extent.
By installing air conditioning into the home or workplace you’ll benefit in many ways. Here are what we consider to be thetop benefits of air conditioning for the home.
An air conditioner is a system or a machine that treats air in a defined, usually enclosed area via a refrigeration cycle in which warm air is removed and replaced with cooler air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air
compressor is a specific type of gas compressor. Compressors are
similar to pumps: both increase the pressure on a fluid and both can
transport the fluid through a pipe.
Anhydrous ammonia is frequently used in large commercial systems, and sulfur dioxide was used in early mechanical refrigerators. Carbon dioxide (R-744) is used as a working fluid in climate control systems for cars, residential air conditioning, commercial refrigeration, and vending machines.
The water flows from the chiller to the application’s point of use and back. … In industrial water chillers
is the use of water cooling instead of air cooling. In this case the
condenser does not cool the hot refrigerant with ambient air, but uses
water that is cooled by a cooling tower.
The refrigerant used in mobile air conditioning systems. Vehicle manufacturers have used two different refrigerants in automotive A/C systems. Most pre-1994 model year vehicles used CFC-12 (also called R-12; most people know it by its most popular brand name, Freon™).
Should You Repair or Replace Your Air Conditioner? … To begin with, replacing an air conditioner can be a pricy endeavor, so make sure that your old AC unit is on its last leg before doing so. To be clear, in most circumstances, an air conditioner can be repaired
5 Common Signs That You Need to Replace Your AC Unit
- Lack of Cool Air & Limited Airflow. This is probably the most obvious sign that your AC is experiencing issues. …
of Moisture. All AC units will create moisture to some extent, but
those which are functioning properly should be able to handle it without
- Strange Sounds. …
- Foul Smells. …
- High Energy Bills.
With mild to moderate use, they can last twice as long. However, it is not unusual for air conditioners to last 20 to 25 years when they have been maintained properly over the years. If you want to get the most out of your air conditioner, make sure to have a licensed professional perform annual AC maintenance.
If an air conditioner or heat pump outdoor unit is 10 years old and needs to be replaced, the indoor unit is just as old and has been subjected to the same amount of wear and tear. Replacing both units means you won’t have to replace the indoor unit in a short time—you‘ll have years of service from both units.
Yes, but the degree of sealing depends on the needs of the client. For example, hospitals and labs need their cold storage rooms fully sealed and secured so whatever they are storing in their rooms will not be contaminated or vice versa. For supermarkets, all they need is a room to keep the cold in
It depends on your requirements. The colder it is the more expensive and advanced it will be. It’s also more difficult to maintain lower temperatures, therefore most will also use it together with temperature control.
They can be used for anything if a client needs a place cold place to store something. Usually they are perishables like food, or temperature sensitive items, like blood or medicine. Cold rooms are also used in the IT industry, which uses them as a place to store their servers.
If refrigerators come to mind when you think about cold storage, it’s pretty close, but that’s only the tip of the iceberg. Cold storage is also about everything that has to do with refrigeration, like room insulation, drainage, room design, and construction, which we all handle as part of our services.
Since as much as 50% of your building’s energy consumption is used by your HVAC system, it’s smart to look for ways to make your system use less energy. Here are a few tips:
- Upgrade to a newer high efficiency air conditioning unit. According to the U.S. Environmental Protection Agency (EPA), every dollar invested in energy efficiency can produce a double or triple return on investment. Upgrading to high efficiency equipment can pay for itself in a surprisingly short period of time.
- Choose ENERGY STAR labeled systems. According to the US Department of Energy, these systems can save you $3 to $4 per square foot over the life of the equipment. In addition, you also may be eligible for rebates from your utility company.
- Perform an energy audit to determine your usage needs, then install programmable thermostats to decrease usage when it’s not needed. For larger buildings, install zoning and Building Automation Systems to have more precise control over energy usage.
- Install economizers, which measure outside air to determine when it’s cool and dry enough to provide comfortable conditions inside. If it is, outside air is used instead of running the air conditioner, reducing energy usage.
- Have your system regularly cleaned and tuned up. Dirty systems with worn parts must work harder to produce the same results, and use more energy in the process.

If you’re considering installing a new air conditioning unit, you’ve probably run across many rating acronyms on the sales literature. If it’s all greek to you, here’s a quick explanation of the various ratings:
- EER (Energy Efficiency Ratio) is a measurement of the cooling output of an air conditioner divided by its energy usage, calculated under specific test conditions that represent peak load. A higher number means a more energy efficient system.
- SEER (Seasonal Energy Efficiency Ratio) measures the efficiency of cooling equipment, calculated based on a seasonal average instead of at specific laboratory conditions. A higher the SEER rating means the unit is more energy efficient.
- HSPF (Heating Seasonal Performance Factor) measures the efficiency of the system’s heat pump. Again, a higher number means a more efficient unit.
The best thing you can do to prolong the life of your system is to have it regularly serviced by a professional. In addition, here are a few tips for easy things you can do to avoid costly air conditioning repair:
- Keep leaves and debris from collecting around your outdoor air conditioning unit. This simple action prevents dirt from clogging up your system, and keeps airflow paths clear.
- When arranging furniture layouts and carpeting installations, make sure air grills and ductwork are not blocked.
- Use blinds and shades on west and south facing windows to keep out heat
- in the summer.
- Use programmable thermostats to reduce air conditioning usage when it’s not needed.
You’re right to be concerned about the humidity in your building. Levels that are too high or too low are one of the leading causes of poor indoor air quality, and can result in mold growth, the spread of airborne illnesses, and even computer breakdowns.
When properly designed and controlled, your air conditioning system definitely should keep the air in your building at between 40 and 60 percent relative humidity. While there are a number of methods used to help your air conditioner remove humidity from the air, the most efficient methods involve using heat generated by the air conditioner itself to cause the unit to run long enough to remove more moisture from the air. If your building is too humid or too dry, your HVAC tech can check if your humidistat is properly set, or if your system requires maintenance.
An air conditioning system that needs recharging of refrigerant on a regular basis is leaking and needs repair. Leaking refrigerant not only causes your unit to lose cooling capacity and use more energy, it’s also very bad for the environment. Refrigerant gases released into the atmosphere are one of the worst culprits in depleting the ozone layer.
Be sure to choose a service provider that uses the latest technology to find refrigerant leaks, since the old methods are very time consuming and will cost you more money.
Depending on your system, it should be serviced a minimum of once a year, with periodic inspections up to 4 times a year. We suggest scheduling a consultation with a leading HVAC service company that has respected industry certifications such as MSCA Star. Based on the age, size and usage of your system, a quality service provider can tailor a service plan to meet your budget requirements and keep your system running reliably.
