How expensive is a new air conditioning and heat pump system?

Not all heating or air conditioning systems cost the same. Many factors affect the cost of a new system: the size of your house, the age and condition of the duct work, the thermostat and whether you have an electronic air cleaner will cause price to change.

An energy expert can provide a operating cost comparison for any unit a consumer is considering. For someone with allergies, an ECM motor connected to an indoor unit will allow the homeowner to circulate the air in a home while at the same time filtering the air of allergens and pollutants. The cost is minimal, about the same as operating a light bulb. Many systems offer a payback which means the monthly savings of a new unit will offset the cost over time.

How does an air conditioner work?

An air conditioner doesn’t actually add coolness to a home, but rather removes heat from the air indoors and transfers it to the outdoor air. Heat from the indoor air is extracted when it passes across a cooling coil located in the indoor AC unit. When the hot air indoors passes over the cold evaporator coils, a refrigerant inside the coils absorbs the heat. In order to maximize efficiency, the air conditioner coverts the gas inside the coils back to a liquid by placing it under high pressure. A great article on the intricacies of the air conditioner is at

The heat created from this compression is sent outdoors through a set of condenser coils and a fan. This endless cycle continues until the optimal temperature is reached inside. Frank will ensure your system always reaches the optimal temperature:

There are two activities happening in an air conditioner. First, the refrigerant inside is chilling the indoor air creating a gas. This gas is being compressed, cooled, and then converted back to a liquid. Once this happens, the heat is released to the outside air and the inside air remains cool.

What size air conditioner unit do I need for my home?

When building a new home or replacing an old air conditioning unit, many people wonder what size unit to purchase. Thinking of the children’s story Goldilocks and the Three Bears is a good guideline when purchasing a new or replacement unit: too small and your unit will not cool properly, too large and you are wasting money, but just the right size will provide you with comfort and savings

Frank Weglarz and Action Air HVAC Construction Inc. can provide a load calculation for your home or office. Many dealers will also provide an energy analysis to give you a rough estimate on operating costs. Knowing the efficiency of the unit and your budget are also factors to consider when thinking about a new air conditioning unit.

How do I know if my existing unit is covered under warranty?

Many units that are older than 5 years old no longer have an existing warranty However, if you are unsure of how old your unit is, locate the label on the outer surface of the equipment for a manufacture date. This is the age of the unit.

Since warranty terms and conditions will change for each manufacturer and installation company, you will need to contact the company for specifics.

The Frank Weglarz and the experts at Action Air HVAC Construction Inc. can provide an inspection on your existing unit and recommend whether you need a replacement unit or not.

What are the different parts of an air conditioner?

A standard air conditioner has four major parts: evaporator, condenser, expansion valve, and compressor. Not only do air conditioners cool the indoor air, they also monitor and regulate the temperature of the indoor air with a thermostat. Filters remove airborne particulates from the air. Air conditioners also function as dehumidifiers. When the air outside is humid, an air conditioner will discharge water. More on that at

The evaporator receives the liquid refrigerant. The condenser takes the heat from the inside to the outside. The expansion valve regulates the flow of the refrigerant into the evaporator, and the compressor pumps the refrigerant. Frank goes into more detail about what this means for your home on his website

Think of an air conditioner as having two sides: a cool side and a hot side. The evaporator is on the cold side of the unit and with the use of a fan, blows air over the chilled coils releasing cool air into a room. The hot air is on the other side along with the compressor and condenser. In between these two sets of coils is an expansion value. Once here, the evaporator drops the pressure changing the refrigerant gas into a gas allowing the heat to escape. The compressor is actually a large pump that puts pressure on the refrigerant gas in order to turn it into a liquid so it can return inside and cool the air once again.

Why is ventilation so important?

Natural ventilation is obtained by simply opening a window. However, if a homeowner is paying money to cool or heat their home, they do not want to waste money on an open window. Homes have become, in effect, sealed from the outside to improve efficiency. Tips on ventilation can be seen at

Air leaks have all but been eliminated from homes with the use of weather stripping and caulk guns. Unfortunately, this means that the same air is recirculated around a home trapping pollutants and other unwanted particles into the air. Keep this in mind and read more at

Should I be concerned about the quality of the air in my home?

There are many products on the market today that allow the homeowner to measure the indoor air quality (IAQ) of their home, which can be seen at Once a consumer understands the possible health effects from unhealthy air, they can then measure the quality of their air and then manage it. The new devices on the market that monitor air quality allow the home builders to use products that increase air quality. Elements such as carbon monoxide, carbon dioxide, organic compounds, humidity and temperature can now be measured. Allergies, odors, illnesses, and more can be caused from poor IAQ. Frank Weglarz has written a great piece on that and it can be seen at

Professional tools have better sensors and are much more expensive, but may be needed to determine the exact cause of poor IAQ.

When building a new home, experts like the ones at Action Air HVAC Construction Inc. can determine the best materials to use along with the best system to install to give the homeowner the best IAQ. In addition, substantial energy savings from 30 to 70 percent can be realized in homes that have carefully planned their HVAC upgrades. Visit us at and we can get you started.

How long should a new system to last?

Industry experts suggest that a new unit should last between 12-15 years if properly maintained and with regular preventative service measures. All heating and air conditioning systems along with ventilation require regular and proper maintenance to maintain maximum efficiency. Frank Weglarz has a blog at with maintenance tips.

However, even if homeowners are vigilant and proactive in maintenance, many systems will only last a maximum of 20-25 years. If you live close to a sea coast, this number is reduced due to the outside conditions of the air. At the page you can read more.

A gas furnace should last from between 15-25 years. Heat pumps will last around 15 years also. If you have a tank less water heater, expect a 20 year life before a replacement is needed. With rapid technological improvements, thermostats will usually be replaced before their 35-year lifespan ends. Read about tank less water heaters at

Should I replace my existing heating or air conditioning system?

There are many factors to consider when replacing an existing air conditioning or heating system. The age of the unit, how efficient the current unit performs, and if the current unit is in need of repair. With increases in HVAC technology, many of the units made a short decade ago perform less efficiently than once made just a few years later. Frank ( says that his top of the line today perform 3x better than the top of the line just 5 years ago.

Systems today may be as much as 60% more efficient. Also, previous maintenance, or lack thereof, can cause wear and tear on a system that would reduce the actual efficiency of the unit. A reduction in utility bills and an expensive repair bill are other factors to consider. Read more:

What is involved in replacing an old system?

Before deciding to buy a new system, let Frank Weglarz and Action Air HVAC Construction Inc. ( inspect several items to determine whether certain items need to be replaced and the cost effectiveness of replacing these items offsets the cost of a new unit.

For example, ductwork, insulation, wiring, electrical service, thermostat, filters, drain pans and evaporator coils are just a few of the parts that a qualified service repairman will need to check. If several parts of an old unit need replacing or will wear out within a short amount of time, homeowners may be better off replacing the entire unit for a more cost efficient one.
