You can always count on Elins for the best products, parts, accessories and experts.



Our technical services team, Black Tech, performs complete home air conditioning installations as well as AC relocations and upgrade installations. Our team is able to install all kinds of residential HVAC systems ranging from ductless and ducted systems, surface or conduit piping for ductless systems, multi-zone systems and more.
First, Black Tech conducts a preliminary site inspection to gather the necessary information about the specifications of the room(s) for an effortless installation operation. After the information has been compiled, we give a free consultation to ensure adequate dissemination of information and to familiarise you with Black Tech’s mode of operation. Thereafter, we come in fully prepared and adequately equipped with our tools and equipment and install your air conditioning system seamlessly with our wealth of expertise.
All home air conditioning installations come with a six month or one-year labor workmanship warranty depending on your service agreement with us. We have been in business for more than 30 years because of our outstanding services.



Thousands of homeowners each year specifically request, or unknowingly pay, to have an oversized/undersized HVAC system installed in their home. A properly designed air conditioning system is very important when cost and efficiency is taken into consideration. The residential conditioning design process begins with a free consultation from one of our highly trained technical professionals and engineers. We guarantee immense satisfaction and top-notch designs exclusively mapped out for your needs.

Maintenance of an AC/Refrigeration system is very important in order to increase the lifespan of the system, reduce the cost of repairs in the long run and to ensure that your system is running at high efficiency. Detection of faults in an AC system can also be detected in time in order to avoid further deterioration of the system. This is done by frequent servicing of the HVAC-R system quarterly, biannually or annually depending on your needs.

HVAC is short for Heating, Ventilation and Air Conditioning. HVAC is most oftenused to depictthe whole heating and cooling system consisting of the duct work, air filters, humidification controls, and registers.

Is it making strange noises? Is it cooling or heating all areas of your home sufficiently? Has it been taking longer to cool down or heat up? Have your utility bills been rising for no apparent reason? Any of these are signs that you may have a problem that needs service. In most cases, the longer you delay, the worse any underlying problems will get. So be sure to contact Horizon Services to check out your system whenever you notice anything out of the ordinary.

According to studies created by the U.S. Environmental Protection Agency, exposure to air pollutants indoors can be 100 times higher than outdoors. Frequent dusting and vacuuming can help reduce the amount of dust.

Temperature settings depend on the time of year and your personal preferences. In the summer, the average temperature setting is 75°-80°. In the winter 68°-72° is the norm. Remember, when leaving your house; try to avoid drastic temperature changes. Do not set your temperature back more than 5°; this will cause your unit to work harder to achieve the desired temperature setting.
