I'm on Long Island, so I imagine you wouldn't know the going installation rates for my area. However, would you have a ballpark figure of what it might have cost you if your unit was strictly A/C, and without the added insulation? This site has prices for units only: How Much Does a Mitsubishi Ductless Air Conditioner Cost? They list the unit we have (18,000 btu, 26SEER) as $3k, pretty sure we paid a bit less than that, given all our costs. The installation will be the same, I think, on an A/C only unit as an A/C/heat unit. The installation required a 20amp 240 volt service and an exterior electrical outlet within 25 feet (don't ask me, the county said on the permit that it is current county code to have an outlet for servicing exterior heat/cool units). The heat pump box was mounted on the side of the house above the snow line, insulated fluid (refrigerant) cables run up two and a half stories to the attic, across the attic and into the back of the head unit on the wall.

So they were up in the attic anyway. My impression, looking at the bill, is that the install portion was just under a grand. That included two "service visits" as well, at 6 months and a year, to check on the system, clean the 4 filters, etc. ac unit not cooling houseThe electrician was from the same company that put in our 4.8kW solar panels, so I think we got a deal from them.best air handling units The Fed and state rebates came to about $400, based on the size we were heating vs the size of the house, with the state chunk being the larger.how much does it cost to install ac unit 33,571 posts, read 32,296,961 times Originally Posted by nitram Would you happen to know how many zones? 168 posts, read 266,010 times

They can produce heat down to 15* and sometimes lower without any additional source.Click Here for DetailsDuctless heating and cooling in one system can start fully installed and ready to turn on for as little at $2499, and the price goes up from there depending on a number of factors. By now you may already know that ductless is a quiet, efficient heating and air conditioning solution for your home that will reduce your energy costs and in some cases, pay for itself in energy savings.But, what can a homeowner expect to pay for this modern, convenient heating and air conditioning solution in the greater Boston area?Ductless mini-split technology has been around for more than 50 years, but has only been available to New England homeowners for about thirty years.

In Japan, ductless accounts for 90% of all HVAC systems sold, and more than 80% in Europe. Unfamiliarity with ductless technology and spotty access to educational information has slowed the growth of ductless acceptance in the United States, but the efficiency of ductlesss has caused major utility companies, government agencies and homeowners to take notice. The financial incentives associated with ductless technology have made it one of the fastest growing types of air conditioning in the HVAC industry.So, how much can you expect to pay to have a Mitsubishi ductless system installed in your home? The price of a ductless system is determined by four primary factors: Due to the flexibility of these systems (whole house, partial house, one room, etc.) there are multiple configuration possibilities that can slide your job from the lower end of the cost range to the highest. A ductless system, on its most basic level, consists of: Professional installation of the most basic, or single zone, configuration (consisting of one wall unit and condenser) will cost between $2,800 and $4500.

This layout is ideal for many kinds of applications like conditioning the air in a sun room, garage, attic, and some smaller homes. A single ductless unit is perfect for keeping a sun room comfortable all year long Some New England homeowners need only one ductless unit, while other applications are better served by 3, 4 or 5 units. It all depends on the layout of the home and what works best for you. A multi-zone system consisting of two indoor evaporator units typically run between $7500 and $8000. We can run as many as five indoor units with a single outdoor condenser, and we can come back to add indoor units at a later date if you want to have your system designed for future expansion as budgets allow. A 5-zone system will run you between $18K and $22,000. At first glance, the cost of ductless heating and air conditioning can seem steep, however, the benefits in energy efficiency will save you a lot in the long run.Since there are no ducts, you won't waste energy via leaky ductwork.

Typical forced air systems experience duct losses equivalent to about 20% of the system's energy consumption. Ductless systems are also less expensive to maintain than traditional systems. When you add in attractive rebate programs and 0% payment plans, ductless solutions wind up shaking out as a net cost savings to most homeowners. A multi-zone configuration comes with an additional energy saving benefit. You can control the temperature independently in every room where an air handler is installed.So, if you're not using a room, you won't have to keep it heated and cooled the same as the rest of the house.Finally, you'll need a qualified installer, like NETR, Inc., and, as I mentioned earlier, there are some good reasons for that (beyond the fact that it's us. :-))If you're interested in ductless for you home, give NETR, Inc. a call at 781-933-6387, or click the button below to learn more and schedule an appointment.Want to be comfortable and save money? A heat pump is one of the most advanced and efficient heating and cooling system available today.

Types of Heating & Cooling Systems Electric furnaces come in a variety of configurations and are similar to gas-forced air furnaces. Most electric furnaces are multi-flow units, meaning that the same unit can be positioned in a variety of ways: upflow, downflow or horizontal. Compared to electric baseboard heating systems, forced-air electric furnaces provide the advantage of a centralized air handling system with air filtration, humidification and control of air distribution. Investing in a central electric furnace system is worthwhile if you plan on filtering the air and/or if you plan on installing a central cooling system. Fan-coil wall heaters are controlled by thermostat and use an internal blower to force air over a resistance coil. Since they provide heat via forced air, no fins are needed on the electric element. Wall heaters are available in a number of configurations and sizes to fit various space heating considerations.

Because these units use large volumes of air as their heating medium, they’re not as large as baseboard units of the same heat output, and location isn’t as critical. Electric wall heaters are easy to install since wiring is the only connection needed. These units offer the advantage of individually controlled zones of heat throughout the house. This system can decrease energy use while increasing comfort. In the past, the major drawback of these units was fan noise. However, many of the new units are quiet enough to use in a bedroom. Electric wall units contain resistance elements, similar to baseboard heaters, and rely on radiant heat and natural convection as well as forced air. They’re generally used for small rooms or areas like entryways or bathrooms. Wall heaters operate quietly, they distribute heat pretty quickly, and they make zoning a breeze. Of course there are some disadvantages. Wall units are very visible. Installation can interfere with the wall insulation and make furniture placement difficult, and less expensive units can generate some fan noise.

In most homes, as much as 50%* of your monthly utility bill goes to heat and cool your home. A heat pump is one of the most advanced and efficient heating and cooling systems available.

Types of Heat Pumps A dual-fuel heat pump uses a combination of two technologies to provide comfortable and efficient heating and cooling year-round. A dual-fuel heat pump is an air-source heat pump designed that works in conjunction with a forced-air furnace heating system. The major different between a standard energy-efficient heat pump and a dual-fuel heat pump has to do with the auxiliary heating process. During severe winter weather when outdoor temperatures drop below 35 degrees, a heat pump has to use an alternate source of heat. With a dual-fuel system the forced-air furnace takes over automatically to provide constant heating comfort. The forced-air furnace can be new or existing, and can be fueled with natural gas or propane. The dual-fuel heat pump works in conjunction with your present furnace, regardless of fuel type. To learn more, call 1-800-524-2421. An underground system with special refrigerant piping, the geothermal heat pump uses the near-constant temperature of the earth for its heating & cooling source.

VRFs do not have ductwork as a component of the overall system. They serve as a great application for homes and living spaces where installing ductwork is not possible or desired. Commonly known as a ductless heat pump, a VRF system allows one outdoor condensing unit to be connected to multiple indoor units. Typically, these indoor units can be mounted on the wall or ceiling and come in a variety of styles. Each unit has its own thermostat, providing the right amount of heat or conditioned air for that zone.

In addition, both heating and cooling can occur at the same time with a VRF system. So if the bedrooms in the back of the house need cool air, while the front of the house requires heat, the system can handle it. VRF systems offer many benefits including increased energy efficiency, design flexibility during renovation or construction and quiet operation. Systems can be controlled with a central monitoring application that allows users to control the entire system from a single location or via the web. There is minimal energy loss with VRFs as compared to 30-40% energy loss with traditional forced-air systems that use ductwork in unconditioned places like attics. By operating at varying speeds, VRF systems work only at the needed rate, allowing for substantial energy savings. Radiant heaters distribute heat the way the sun does, using radiation. Like heat from the sun, heat from a radiant heater travels outward striking objects directly in its path. The heat is then conducted from the heated surfaces to the surrounding air, where it sets up convection currents, gently distributing heat to the space as the warmed air rises.

Radiant heat is popular because most people find it comfortable (although it is not always the most economical way to heat)—they feel warm from the radiation, even though the air around them may be cooler than would normally be comfortable. Homes equipped with electric radiant heating systems have no furnace, ducts, flue, or chimney. The heating elements may be ceiling-mounted electric resistance wires installed between two layers of wallboard or just beneath the plaster. This location is convenient because, from the ceiling, heat can easily radiate to the floor, walls and occupants. However, places producing “shadows”—like under tables, for example—may feel cold because they do not receive direct radiation. In mild climates, the radiant heat wiring is often located in the floor, usually embedded in a concrete slab. Baseboard panels, wall heaters and portable units are also used for resistance electric heating. Another familiar form of radiant heat is the heat lamp commonly used in bathrooms to take the chill off people exiting the shower, and in cold garage work areas.
