Demand controlled kitchen ventilation (DCKV) is a building controls approach of slowing down kitchen exhaust fans and subsequent supply air in response to the actual cooking loads in a commercial kitchen. Traditional commercial kitchen ventilation systems operate at 100% fan speed independent of the volume of cooking activity and DCKV technology changes that to provide significant fan energy and conditioned air savings. By deploying smart sensing technology, both the exhaust and supply fans can be controlled to capitalize on the Law of Affinity for motor energy savings, reduce makeup air heating and cooling energy, increasing safety and reducing ambient kitchen noise levels.[30]

We want to compliment your fine sales and installation team. They are outstanding. Carlos, your sales rep., was highly informative. We reviewed our needs and we ultimately chose the Trane XV-18 variable speed system. Carlos did not try to up sell us with things that we did not need but he did help us choose the correct upgraded filter and UV light that we wanted. We told Carlos that our research indicated that the quality of the installation of the unit was at least as important as the unit itself, and Carlos agreed. Carlos pointed out that new proper sized duct work and copper wiring would be required for a correct installation, and that we needed to add two more returns. We asked if more returns were needed and Carlos said that would not be cost effective. That was great to hear. Carlos assured us that the installation team of Willie and Gary, both lead installers, would be used. They were both superb. They came on time and worked for 12 and 1/2 hours. It was a 93 degree day so the heat in the attic was intense. We kept telling them to take a break but they continued to work up there in what must have been 130+ temperatures. They were amazing! They were neat and cleaned up any mess they made. They patiently answered all of our many questions and gave us helpful tips. They were truly professional in all respects. We also note that Stacy, Angie and Karen of your office staff were each courteous, accommodating and efficient. They helped things to go smoothly. Carlos, Gary, Stacy, Angie, Willie and Karen are each great assets to your company. We would be comfortable recommending that team of people to anyone! Ken and Kathy Luban
If the condenser coils are clogged, the compressor can overheat and shut down. You’ll experience intermittent periods of minimal cooling, followed by no cooling. Even if you’re “sure” the condenser coils are clean, clean them again. Turn off the power. Flip the air conditioning service and furnace circuit breakers in your main electrical panel to the “Off” position. Next, turn off the power switch right at the furnace or air handler. Then yank the disconnect block (Photo 1) and clean the condenser coils (Photo 2). If the air conditioning service still doesn’t work properly after you’ve cleaned the condenser coils, installed a new filter and opened all the supply vents, proceed with the following repairs.
1) Change your filter. The simplest and most effective way to keep your AC running smoothly is changing your filter once a month. By regularly changing your filter, you reduce a lot of the burden on your system. A dirty or clogged filter makes your air conditioner work much harder than does a clean filter. Changing your filters regularly is easy on your budget and easy on your system as well. It will lower your utility bill and extend the life of your AC.
You might guess it from the name: the heat exchanger is the part of your furnace that actually heats the air your blower motor pushes through the furnace. It consists of a chamber in which the heat energy produced by natural or propane gas is transferred to the forced air. At the same time, this part also includes a vent through which the gases themselves are safely removed from the unit and the air that enters your home. Because of these gases, a problem with your heat exchanger needs to be dealt with promptly. Over time, cracks in the exchanger can result in carbon monoxide leaks. Taking care of the problem once again means understanding the existence of a range: repairing your heat exchanger can cost as little as $100, but a full replacement may cost up to $1,200.
The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window. This process also made the air more humid, which can be beneficial in a dry desert climate. In ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season.[5]

An air conditioning system, or a standalone air conditioner, provides cooling and humidity control for all or part of a building. Air conditioned buildings often have sealed windows, because open windows would work against the system intended to maintain constant indoor air conditions. Outside, fresh air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure. The percentage of return air made up of fresh air can usually be manipulated by adjusting the opening of this vent. Typical fresh air intake is about 10%.

The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

The selection of indoor units has one restriction: their total power should not exceed the capacity of the outdoor unit. In practice, however, it is very common to see a multi-split system with a total capacity of indoor units greater than the outdoor capacity by at least 20%. However, it is wrong to expect better performance when all indoor units are turned on at the same time, since the total capacity of the whole system is limited by the capacity of the outdoor unit. Simply put, the outdoor unit will distribute all its power to all operating indoor units in such a way that some of the rooms may not have a very comfortable temperature level. However, the calculation of the total power is not simple, since it takes into account not only the nominal power of the units, but also the cooling capacity, heating, dehumidification, humidification, venting, etc.
An electric furnace provides warmth by moving air over and through a series of coils. Ductwork and vents then distribute that air to the individual rooms in your home. Repair costs will depend on both the brand and the exact nature of the problem, but tend to be lower than some of the options above. That's because the units are small, and issues tend to be contained within the heating elements themselves. Expect to spend less than $300 on your electric furnace repair, depending on the exact problem.

Since the 1980s, manufacturers of HVAC equipment have been making an effort to make the systems they manufacture more efficient. This was originally driven by rising energy costs, and has more recently been driven by increased awareness of environmental issues. Additionally, improvements to the HVAC system efficiency can also help increase occupant health and productivity.[24] In the US, the EPA has imposed tighter restrictions over the years. There are several methods for making HVAC systems more efficient.

If your home is not heated using forced air, chances are a boiler will make sure you stay warm during cold nights. A hot water system delivers hot water through a network of pipes that run to every room in your house. The heating effect gets maximized through radiators. The most common issues with hot water heating tend to be not be major, but small problems that add up over time. Mineral deposits within the water tank, a pilot light malfunction, or an issue with a radiator itself can require professional repair. On average, you will pay between $183 and $582 for these problems. The exact amount will depend on the exact problem, as described in our boiler repair cost guide.
7) Schedule an annual tune-up with an HVAC professional. A trained HVAC technician can detect most problems before they become major ones. With a cost of around $100 for a routine maintenance call, the benefits will likely outweigh the costs by a considerable margin. A typical tune-up will include various tests to ensure your unit’s internal parts are functioning correctly, as well as a filter check, and a refrigerant charge if needed. Your technician will likely also clear the drain, and clean your unit thoroughly inside and out.
