HVAC experts out there... I live in Wisconsin and it gets mighty cold here! I have a condo with 2 wall units that are used for both air conditioning and heat. My heat bill in the cold winter months can get up to near $300 per month (normally my bill is about $100 +/- $10 during the spring/fall and is about $200ish in the summer with the air on). If I keep one of the units on in the living room and turn the one in the bedroom off, my electricity bill is higher. It seems strange but true. If I have both running, they turn on and turn off every 10-15 minutes. They work with my thermostat and whatever it's set to in each room. Whether I have a unit turned off or not, and go next to it, I feel an extreme cold air coming in through it's vent. I think when it turns off (when it heats the room up to the desired temp), that area cools down and it was like not heating it at all. Seems to be a bad vicious cycle. I guess I'm looking for advice to prevent that heat loss, or to prevent the cold air from coming in from outside.

It's about 2 degrees outside. If you want pictures (or make/model numbers) let me know. heating hvac air-conditioning heater cooling You can install an insulating cover on the inside of the unit.

This comparison guide lists the pros and cons of each system type, along with a current estimated cost for each style. Please note that costs for each system type vary by manufacturer, and the size of the unit needed depends on several factors along with square footage such as area layout, proper insulation, and no leakage around doors and windows. HVAC Air Conditioning and Heating System

A standard HVAC heating and cooling system is cost effective and convenient, but it also has some drawbacks to alternative systems. Pros of HVAC Units: HVAC systems provide overall cooling and heating to every room that is equipped with a vent connected to a network of ductwork.portable ac unit for vehicle Systems will cycle on and off as the interior temperature needs to be adjusted.cost of ac compressor unit The standard for sizing is 1 ton per for every 500 square feet. portable ac power billFor a 2,400 square foot property, you would need a minimum of a 5-ton unit. For an HVAC system for a 2,400 square foot area in Los Angeles, California, the low cost is approximately $3,904.56 and the high end is $4,825.80. This is for a 3-ton unit with a Seasonal Energy Efficient Rating of 18.

Cons of HVAC Units: Ductwork can be expensive and prone to leaking when damaged or due to deterioration from age. If you’re having a new system installed to replace or upgrade a current system, the ductwork may need to be updated or modified as well, to ensure it is compliant with the new system. For a new installation, you must factor in the cost of the ductwork and labor. Unlike a ductless system, you cannot individually adjust the temperature for each room. Window Unit Air Conditioning System Whether they’re installed in a window or a wall, this unit has been heating and cooling homes and businesses for many years, and with today’s technology, they have improved in energy efficiency. Pros of Window Units: Window units come in a variety of sizes from 5,000 BTUs to 36,000 BTUs and are available for cooling only or for heating and cooling. These units are affordable, with current prices ranging from less than $400 to approximately $1,500.

Window units are relatively easy to install—simply place in an appropriate window and provide support. Cons of Window Units: Since the unit is installed in either a window or in the wall, it is not as versatile as a portable unit. Because the unit does not have a duct system with vents to every room, the immediate and surrounding area will feel the effects of the cooling sooner, while outlying areas will take more time to condition. A 12,000 BTU window unit is estimated to cover between 450 and 550 square feet. For a 2,400 square foot area, at least two 18,000 BTU units (18,000 BTUs covers up to 1,000 feet) are needed or one 28,000 BTU unit, which covers 2,200 square feet plus an additional 10,000 BTU unit to cover the remaining 450 square feet. Portable Air Conditioning System Portable air conditioners are an option known for their versatility. Here are a few things to consider when doing comparison shopping. Pros of Portable AC Units: The beauty of portable units is the ability to move them whenever and wherever you like.

By removing the drainage tube and window kit used to vent the hot air, the system is easily moved because it’s equipped with casters. Units are affordable, with prices ranging from less than $500 to $1,200. Portables are available in 8,000, 10,000, 12,000, 14,000 and 16,000 BTUs. Systems are available for cooling only, or for heating and cooling. Cons of Portable AC Units: Homes or offices with carpet may find it difficult to roll the unit. A 12,000 BTU covers an area of 400 square feet. Six units are necessary to accommodate a 2,400 square foot area. Portables tend to have a lower Energy Efficiency Rating (EER). Ductless or Mini-Split Air Conditioning and Heating System Mini-split ductless systems are a newer option in heating and cooling. The unit is comprised of an external compressor/heat pump and internal inverter boxes that connect to the compressor. The boxes can be wall, floor, or ceiling mounted. Lines are run from the inverter box to the compressor;

one copper for refrigerant, electric wiring and tubing for drainage and condensation. Pros of Ductless AC Units: Mini-splits are ductless systems, which save money on the installation of a network of ductwork throughout the ceiling. A slim duct line ductless system is also an option, which uses minimal ductwork. Each inverter box is individually regulated with a remote, meaning you can turn off units in rooms not needing heating or cooling. Systems can be ordered with 1 to 8 inverter boxes depending on your needs. Systems use 208-230 voltage. Ductless systems come with a high Seasonal Energy Efficiency Rating (SEER) and Heating Seasonal Performance Factor (HSPF) that measures the efficiency of the heat pump. Cons of Ductless AC Units: Systems are available with 12,000, 18,000, 24,000, 30,000, 36,000, 42,000 and 48,000 BTUs. A Multi-Zone (5 boxes) with 36,000 BTUs is estimated to cover 2,000 square feet. For homes or businesses with more square footage of 2,400 square feet, the addition of a single 12,000 BTU system with an inverter box may be necessary.
