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.


Stay away front his company!!! In 2008 I had the company send Rick a technician to do warranty work on my new house. I complained about my house being hot in the summer. Tech said that I had a delta t of 14 degrees (the difference of temp coming into the return and out the supply) and that system was functioning properly. Unfortunately I took their word. After 8 years of being hot I called a reputable company to come and check my system again. The HVAC system still operating with a delta t of 14 degrees. The new company looked at my HVAC system owner manual. They calculated my dry bulb temp and wet bulb temp and used the chart in the owners manual to determine that the system wasn't functioning properly. After the new company came a put two pounds of freon into my HVAC system I now have a 20 degree Delta t. Do not do business with this company not trust worthy!

Many homes in Portland don't have air conditioning of any kind. Whether your home is decades old or just a few years, the wisdom is that the moderate climate of Portland will be enough to keep you comfortable. In fact, when building a home, you typically need to request air conditioning installation from your home builder. With an average of only two weeks or so worth of days that hit 90 degrees, many people simply can't justify the expense. Of course, HomeAdvisor does see quite a few Portland air conditioning installation requests, simply because so many homeowners don't have central air. If you've decided it's time to indulge yourself or have recently moved into a Portland home without air conditioning, we can help you find a contractor who will help you with any or all of your A/C needs.

In the UK, the Ozone Regulations[62] came into force in 2000 and banned the use of ozone depleting HCFC refrigerants such as R22 in new systems. The Regulation banned the use of R22 as a "top-up" fluid for maintenance between 2010 (for virgin fluid) and 2015 (for recycled fluid). This means that equipment that uses R22 can still operate, as long as it does not leak. Although R22 is now banned, units that use the refrigerant can still be serviced and maintained.

My A/C went out on a Friday and I found this company in the phone book on Saturday morning. They came out just a few hours later and it was decided that I needed a new system. The pricing was good as well as the customer service. They brought me a temporary portable air conditioner for Saturday night and they replaced my system on Sunday. This company has the best customer service of any business that I have dealt with. I would highly recommend this company to anyone and have. Great Company!!!!!
Air conditioners can create a lot of water because they remove moisture from the air. To get rid of this, they have a [usually plastic] drain pipe that comes out of the side of the air handler. Over time, algae can block this pipe and, when it does, the AC won’t work. In fact, some condensate drains have a float switch that won’t let the AC run if water backs-up. Water can also puddle around the unit or flood the area. To deal with condensate problems, please see Air Conditioner Leaks Water, below.

In the case of heated water or steam, piping is used to transport the heat to the rooms. Most modern hot water boiler heating systems have a circulator, which is a pump, to move hot water through the distribution system (as opposed to older gravity-fed systems). The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat.
Refrigeration air conditioning equipment usually reduces the absolute humidity of the air processed by the system. The relatively cold (below the dewpoint) evaporator coil condenses water vapor from the processed air, much like an ice-cold drink will condense water on the outside of a glass. Therefore, water vapor is removed from the cooled air and the relative humidity in the room is lowered. The water is usually sent to a drain or may simply drip onto the ground outdoors. The heat is rejected by the condenser which is located outside of room to be cooled.
The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, methyl chloride, or propane, that could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon, in 1928. The name is a trademark name owned by DuPont for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. The refrigerant names include a number indicating the molecular composition (e.g., R-11, R-12, R-22, R-134A). The blend most used in direct-expansion home and building comfort cooling is an HCFC known as chlorodifluoromethane (R-22).

It costs approximately $35,000.00 to properly stock an HVAC air conditioning and heating service van (not mentioning the cost of the van itself), office overhead including marketing, phone, fax, business licenses, professional licenses, insurance, advertising, marketing, and did I mention advertising and marketing, Employee costs including payroll, insurance (out of control), benefits, etc…………, and ongoing training and HVAC educational requirements to remain knowledgeable, competitive, and to retain HVAC professional licenses.
In the refrigeration cycle, heat is transported from a colder location to a hotter area. As heat would naturally flow in the opposite direction, work is required to achieve this. A refrigerator is an example of such a system, as it transports the heat out of the interior and into its environment. The refrigerant is used as the medium which absorbs and removes heat from the space to be cooled and subsequently ejects that heat elsewhere.

Beyond changing the air filter on a regular basis, one of the best ways to ensure your home's HVAC system is operating at peak efficiency is to have a qualified professional HVAC contractor tune up the system on a biannual basis. Energy Star recommends scheduling your system tune-up around the beginning of daylight savings time in the fall and its end in the spring. It's an easy way to remember to have your system serviced before the peak heating and cooling seasons. A standard tune-up is likely to cost you between $70 and $100, but it's money well spent. 
I'll give props to HVAC Service for being available quickly and having Saturday and Sunday appointments. Tony fixed our air conditioner and was professional. So why only 2 stars? Because we sent the receipt into our homeowner association to see if we could get reimbursed for some costs, and the property manager said that we paid THREE times more than we should have. We got conned. I advise you to call HVAC Service, but also shop around and get other estimates. Learn from our mistake!

The most recognized standards for HVAC design are based on ASHRAE data. The most general of four volumes of the ASHRAE Handbook is Fundamentals; it includes heating and cooling calculations. Each volume of the ASHRAE Handbook is updated every four years. The design professional must consult ASHRAE data for the standards of design and care as the typical building codes provide little to no information on HVAC design practices; codes such as the UMC and IMC do include much detail on installation requirements, however. Other useful reference materials include items from SMACNA, ACGIH, and technical trade journals.

Replacement of air filters: dirty filters can lower your unit’s efficiency and cause damage. You can perform monthly checks and cleanings yourself. If your AC is in constant use, you’ll need to replace the filters once per month to keep the unit running properly. Filters typically cost $15-$60. Some filters are reusable, and only need regular cleaning.

Your home’s HVAC system is a fine-tuned piece of machinery. Like your car, your system needs regular maintenance and tune-ups to ensure it is running reliably. Manufacturer warranties for most new systems require annual tune-ups, and for good reason: these preventative maintenance measures extend the life of your system by keeping your system running the way it is designed to run.

If you need a furnace repaired or an air conditioner serviced, we'll send a local technician out to diagnose the specific problem and recommend solutions for you and your family. There will be a diagnostic fee for the visit, and any specific repairs will be an additional charge. If replacing your system is the best solution, the fee for the diagnosis will be credited toward the purchase and install of a new system.
I even asked if this is something they don't do, as in services on a Saturday night.  I was told by the receptionist that they do and I would just be ok calling another company if they is not  part of their services. They again assured me someone WILL call me in 10 mins.  Well, unless their definition of 10 mins is never, then they got it wrong as I am still waiting to be called 5 days later.
    Second, there are the diagnostics involved as well as the return trip to effect the actual repair. What about the hidden costs such as having the part picked up at the supplier, was this considered? As for the parts manager at our shop having wasted time tracking the part down, it often happens that we have to contact several suppliers to find parts especially during the recent cold spell when so many suppliers were out of stock of even the most common service items due to demand being so high. 

Energy efficiency can be improved even more in central heating systems by introducing zoned heating. This allows a more granular application of heat, similar to non-central heating systems. Zones are controlled by multiple thermostats. In water heating systems the thermostats control zone valves, and in forced air systems they control zone dampers inside the vents which selectively block the flow of air. In this case, the control system is very critical to maintaining a proper temperature.
From furnaces to full commercial systems and much, much more, we are committed to fantastic service and meeting our customer’s needs.

Some systems include an "economizer mode", which is sometimes called a "free-cooling mode". When economizing, the control system will open (fully or partially) the outside air damper and close (fully or partially) the return air damper. This will cause fresh, outside air to be supplied to the system. When the outside air is cooler than the demanded cool air, this will allow the demand to be met without using the mechanical supply of cooling (typically chilled water or a direct expansion "DX" unit), thus saving energy. The control system can compare the temperature of the outside air vs. return air, or it can compare the enthalpy of the air, as is frequently done in climates where humidity is more of an issue. In both cases, the outside air must be less energetic than the return air for the system to enter the economizer mode.

"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
