We know that it’s important to you to have your rooftop unit installed with a minimum of disruption to the occupants of your building. That’s why we make sure to have everything in place as quickly as possible. We’ll work within the confines of your schedule as much as possible so that the work is done at a time that’s convenient for you. During installation, we’ll help you decide what type of rooftop unit is best for your building – cooling only or a combination of cooling and heat. Many major brands offer multiple options for heating including staged and modulated gas heat, electric resistance heat, hot water heat and steam heat. Depending on your existing components, we can help design a system for you that will be as efficient as possible. If you don’t already have ducts installed in your building, we provide full ductwork installation services. An air duct installation project can take a bit longer than an HVAC project in which the ducts are already in place, but you’ll find that our technicians are in and out in no time.

Most importantly, you can be sure that the job is done right the first time so your rooftop unit will work well for years to come. Because of the size and scope of most roof top units, the installation process will also include exhaust and supply fan integration and placement of your evaporator coils and drain pans. The exact layout of your rooftop unit depends greatly on the current layout of your roof, the cooling and heating load required for your building, and the brand you choose. Over time, there will inevitably be times when a rooftop unit will need repairs. Call us as soon as you notice an issue with your unit and we’ll have someone out as quickly as possible to assess the situation and complete any necessary repairs. Even if we didn’t do your initial installation, we have the knowledge, skills and equipment needed to complete repairs on any type of rooftop unit. The best way to avoid emergency repairs, though, is to keep up with regularly scheduled maintenance for your rooftop unit.

The cost for these maintenance visits is relatively small, and they’ll save you plenty in repair and replacement costs in the long run. Most manufacturers of commercial rooftop HVAC units recommend maintenance at least once per year. During a maintenance checkup, a skilled technician will complete a thorough inspection of your rooftop unit to make sure all parts are functioning properly. ac unit warrantyThey’ll also clean out any debris or sediment that has built up over time and replace any parts that seem to be wearing down.best buy portable ac unit When seeking out a heating and air conditioning contractor to handle projects involving commercial rooftop HVAC units, it’s important to choose someone who has specific experience working with this type of equipment. miller central ac unit

Pictured here are some of our more commonly installed units, designed to be installed near the cold air side of your central air conditioner's cooling coil. The Original Air Probe Sanitizer™ is the first of its kind on the indoor air quality market. Underwriter's Labs have approved this system for use in HVAC systems. For the protection that you and your loved ones need, the Original Air Probe Sanitizer™ will take care of the job at a moderate cost. Why cut big holes to mount a UVC unit externally? With the model E-200, there's no need to cut holes in sheet metal to clear the UV lamp sockets. The E-200 easily installs inside of or duct near the air conditioner coil (as shown in the installation video). The electrical fittings are on one end as shown. Includes clear Lexan viewport kit for safe visual indication of lamp operation.

Easily flush-mounts on OUTSIDE of duct or other part of system. The two UVC lamps (probes) and sockets fit through two 3.25" diameter holes cut in duct near A/C coil, usually with the hole centers 13" apart . (Rectangular holes can be slightly smaller.) Can be simply fastened in place with four small sheet metal screws, supplied. Electrical fittings are on one end as shown. Includes built-in "light pipes" for safe visual indication of lamp operation. SAME AS E-200 ABOVE, EXCEPT ELECTRICAL FITTINGS ARE ON TOP INSTEAD OF ON THE END (as shown above). Useful in some installations where the A-coil is near the top of the duct or air handler. A 4" x 15" slot can simply be cut in the ductwork to clear the electrical fittings and light pipes on the back of the T-200, should your installation require it. For limited space and very small airhandler installations, such as motel and hotel rooms and small apartment units. Note: Lamp orientation may be different

FME-100L and FME-200L models: The dimension from the socket mounting surfaces (the outside of your duct or air handler) to the ends of the 16" lamps is approx. 16.75" inches. Can I use the Air Probe Sanitizer with my existing heating and air There is no HVAC system which cannot use the Original Air Probe Sanitizer. Nearly all systems can use the E-200 or FME-200 above, but it can be manufactured to fit any size air conditioner (usually at no extra charge). The original Air Probe Sanitizer is made of extruded aluminum and all stainless steel connectors. How does the Air Probe Sanitizer work? Nearly all HVAC (central heating and air conditioning system) systems have the ideal conditions for the growth of mold, mildew, and

other hazardous air pollutants. There are volatile organic compounds (VOC) in the air and also the very common problem of fine organic dust, germs, mold spores, pollen, animal dander, and other allergens. The air in your home, office, school or hospital circulates anywhere from 250 to 400 times per day through the HVAC system. The air passes through the germicidal ultraviolet air purification produced by the Air Probe Sanitizer. The Air Probe Sanitizer produces 2500 times more germicidal effect than the amount in the sunlight that reaches the earth's surface, using a carefully selected, optimum portion of the UV-C ultraviolet spectrum (yes, all "UV-C" light is not the same). After 24 hours, the air you breath will be so clean, you can actually feel and It also generates helpful negative ions and hydroxyls, which naturally occur in the atmosphere, to scrub pollution, odors, and pathogens from the air in your building. The Air Probe is installed safely and out of sight inside your air conditioning and heating

system to kill the source of the problem using the high-energy UV-C form of ultraviolet energy. The original Air Probe Sanitizer uses the UV-C form of ultraviolet air purification. as short wave UV. It has very low penetration abilities, so it cannot go through walls or ductwork. It produces no harmful ozone, gases, radioactivity, etc. same time it has been found to be most effective in destroying the DNA of bacteria, mold, mildew andProperly installed, you cannot be exposed to any ultraviolet light rays (which can be harmful to your eyes or skin) from the Air Probe Sanitizer. products carry the warning "Can cause temporary or permanent loss of vision". be because their UV lamps also emit dangerous UV-B (short wave) ultraviolet radiation (the Air Probe Sanitizer does not). This also represents wasted and useless UV energy. See the lamp comparison chart for more information. But even if someone should look at the Air Probe Sanitizer lamps (not

recommended), the UV-C radiation cannot penetrate the cornea of the eye and damage the delicate retina. Regardless, you should not look at UV lamps without wearing some kind of glasses (you might experience delayed eye surface pain). Properly installed in your central air handler, this will not happen. Does the Air Probe Sanitizer produce ozone?If fact, the UV-C wavelength that the Air Probe Sanitizer's lamps produce would destroy ozone, were it somehow present in the air. Sanitizer is classified as non-ozone producing. It purifies and sanitizes the air with UVC light and hydroxyls, with none of the disadvantages of ozone. The UVC wavelength of the germicidal UVC lamps that are used in the Air Probe Sanitizer (253.7 nanometers) does not produceThe UV wavelength of other brands of UVC germicidal lamps that do produce ozone is shorter, 180 to 220 nanometers. What is the difference between the Air Probe Sanitizer and duct The Air Probe Sanitizer purifies and sanitizes all the air in the building constantly, 365 days per

Duct cleaning and/or sanitizing lasts only one day and does not purify the air. dirty air makes dirty ducts; dirty ducts do not make dirty air. Will it eliminate odors?It will eliminate odor from pets, cooking, mold, mildew, chemicals, paint, carpeting, etc...! Is there any maintenance? The probes (UV-C lamps) should be wiped clean onceThe UV Probes should be replaced once every two years (three years at most), since the lamps' UV-C output drops about 12% per year, and the UV-C output after three years is about 67% of a new probe.For all that it does (sanitizes and purifies the air, reduces dust, destroys odors, sanitizes the ducts and airhandler, helps the a/c run more efficiently - EVERYDAY!) it is very cost effective!Compared with duct cleaning, which really only lasts one day, it would be like cleaning your ducts everyday, plus all of its other benefits. (Remember, dirty air is what makes the ducts dirty toIf it costs $200 to clean your ducts once, it would cost

$73,000 to have them cleaned everyday for a year. Is it easy to install?It couldn't be easier. video shows how simple it is. There are several models to fit any unit. internally-mounted E-200 and the externally-mounted FME-200 comes with mounting screws and cover switch (not shown). good air conditioning man (or mechanical contractor, qualified electrician, etc.) should find this the easiest thing he's ever had to do, and one of theFree tech support is available from us, if needed. Units come with wires for internal installation as shown in above photos. The wires can be replaced with 16/3 cord or covered with flexible metal conduit. NOTE: Direct UV-C light from the lamps is harmful to eyes and skin. Equipment using these lamps must screen them completely Can it help prevent deadly diseases such as H1N1 Swine Flu, H5N1 Bird Flu or SARS?Please see the pandemics page for more If I absolutely cannot install the Air Probe Sanitizer™, then what product(s) do you recommend instead?
