Window Units vs. Ductless Splits for Air Conditioning

Tuesday, May 29th, 2012

If you cannot afford or do not have duct work to support a central air conditioning system, there are two options – window units or ductless units. But, which is better? It depends largely on your budget, whether you rent or own and if there are any risks inherent in either choice.

Window Units

First let’s look at window units. Window units are the least expensive form of air conditioning on the market and don’t require any work on your home to install. They are good for single rooms and smaller apartments as well, and they can usually be installed by one or two people without professional assistance.

The downside of a window unit is that it cannot cool your entire home, even in an apartment. Also, window units tend to block an entire window and they pose a security risk, especially on the first floor. They are easy to remove from the outside and therefore should only be used in extreme circumstances if the window is easy to access.

Ductless Systems

Ductless systems offer benefits that counter all of the downsides of a window unit. Specifically, they don’t block the windows and are mounted inside on the walls. They are also more efficient than window units, using 30% less energy on average than a comparable window unit. They can be sized to cool your entire home and they still don’t use ductwork so extreme installation methods are not needed.

However, a ductless system costs more than a window unit. They are more efficient, quieter, and less obtrusive, but they require a professional installation. Another issue to consider is whether you rent or own your home. Renters may not be permitted to have a system installed like this as it takes up more space and requires some work that could alter the building.

Which Is Better?

So, which should you choose? It depends on the specific needs of your home. If you have two or more zones to cool and can want to have a ductless system installed, it is a great long term solution.

Ductless vs. Duct Air Conditioning Systems

Monday, May 21st, 2012

When it comes time to pick out a new air conditioning system in Bethesda, you will have to make the choice between ductless and duct models. While both of these types of systems have their advantages, the specifics of your situation will go a long way to determining which one is right for you.

Ductless air conditioning systems are becoming more and more popular these days for a number of reasons. For one, they are generally considered more energy efficient than their ducted counterparts. Also, ductless systems are often cheaper and simpler to install, particularly in a house that does not already contain ductwork.

These types of air conditioners use refrigerant lines to connect the indoor unit or units to the outdoor compressor. The refrigerant lines take up much less space than ducts do and they also are much easier to install. Refrigerant lines can also reach into areas of your house that ducts may not be able to, making it possible for you to bring the benefits of air conditioning to places that did not have access to it before.

The indoor unit of a ductless air conditioning system can generally handle the cooling load of one or two rooms, but if you want to cool a larger space, it will be necessary to install multiple indoor units throughout the house. All of these units can connect to the same outdoor compressor and they can also be controlled individually. That means that you can set different temperatures in different parts of your house and you do not have to pay to cool the entire space if no one is occupying certain parts at the moment.

A duct air conditioning system also involves indoor and outdoor components. However, these elements are connected to each other by a system of ducts rather than by refrigerant lines. In a duct system, cooled air is brought inside from the compressor and then circulated through various ducts by the air handler.

The latest duct systems are quite energy efficient as well, and they can also be coupled with zone control systems to create different climate zones within your house. Particularly if you already have some ducts in place, a central air conditioning system can be a great option for you.

What Does an Air Handler Do? An AC Question

Monday, May 14th, 2012

Your HVAC system is a complex system filled with vital components tasked with keeping you comfortable. One of the most important of those component is the air handler – the device responsible for circulating the heated or cooled air produced by your system through the vents in your home and into each of your rooms.

The air handler is a metal box, usually consisting of a blower and the heating or cooling elements. It might also include dampers and sound attenuators along with an air filtration and humidity control system. The simplest air handlers are designed only to transfer the heated or cooled air to the various parts of your home, while the most advanced devices are designed to perfectly condition and clean that air as it is circulated.

 Types of Air Handler

There are a few different types of air handler as well, depending on the size of the HVAC system and the nature of the heating and/or cooling used. Most homes, for example, use terminal units which consist of just an air filter, blower and coil. This very simple system is all you really need to heat and transmit air through your ductwork.

However, for larger systems, there are also makeup air units which use outdoor air instead of recirculated indoor air. There are also packaged and rooftop units which are designed to be placed outside. These devices are most commonly used for commercial applications when space is limited.

How the Air Handler Works

An air handler’s most basic component is a blower fan. This device is run by an AC electric motor and can be either single speed or variable speed depending on the size and scope of your air handler. The dampers on the fan will control the flow rate of the air going through the blower fan. Most residential blowers are part of the air conditioning or furnace system, while commercial systems often have multiple blowers to maintain steady airflow for a larger space.

Because an air handler passes all of the air that will go through your vents, it is the best place to install high quality MERV or HEPA filters to remove pathogens and contaminants. It is also a good place to install humidity control devices to either raise or lower humidity depending on the time of the year.

Your air handler is an incredibly important component in your home heating and cooling system. Without it, all that heated and cooled air you pay for each year wouldn’t reach you. So, make sure to keep your system in tip top condition. If you need any air conditioning service in Gaithersburg, give Tuckers Air Conditioning & Heating a call at 301-670-0034!

HVAC Question: What is a Matched HVAC System?

Monday, May 7th, 2012

It has been about 200 years since the arrival of interchangeable parts during the Industrial Revolution. Today, we laud being able to take a malfunctioning part from a car, computer or vacuum cleaner, replace it with a newly minted part from any number of manufacturers, then keep right on plugging along.

Although this is a blessing in most arenas, when it comes to the HVAC system in your Silver Spring home, it is not necessarily a good practice. Heating and cooling systems work best when they are matched – but what does that mean? And why does it matter?

Why Matched Parts Matter in HVAC Systems

When referring to HVAC systems, a matched system is one in which various components are designed to work together. For example, an air conditioner and furnace made by the same manufacturer can be matched, as can a furnace and a heat pump.

Typically, the matching is done in such a way that the “outdoor” components, such as air conditioners and heat pumps are designed to work best with their “indoor” partners, like air handlers and furnaces. There are also matched systems in which every component is matched to every other.

Efficiency Boosts

While this may seem to make maintenance and repairs a pain, the practice provides a big boost to the efficiency of the system. Because the components were designed and manufactured by the same team to work in harmony, the system performs optimally. Although you can often replace one component of a matched system with one from another manufacturer and have it work fine, the system can lose efficiency, often to a significant and noticeable extent.

For these reasons, it is best to make use of matched systems in your home whenever possible. This means choosing a new matched system to install, replacing broken parts with ones that match the rest of the system and even replacing older systems with newer ones to properly match, when necessary.

It may seem like a hassle at first, but it saves money in the long run by adding increased efficiency over unmatched systems. For more information about how to keep your HVAC system working at peak efficiency, give Tuckers Air Conditioning & Heating a call at 301-670-0034!

HVAC Contractor Tip: The Growing Popularity of Geothermal Heating and Energy

Monday, April 30th, 2012

It’s no secret that use of alternative energy sources is on the rise. Solar panels, windmills and hybrid cars have been heavily publicized over the past several years as people and governments try to employ energy strategies that are more efficient, friendlier to the environment and more cost effective.

One alternative energy option that you may have overlooked amid the press that the above topics have received is geothermal heating. That is, using the existing energy of the Earth as a means to heat and cool your home.

If you have in fact been unaware of geothermal heating and energy thus far, it is rapidly growing in popularity as an alternative energy and heating source. According to an article in GOOD Magazine, there are projects currently underway that would double the United States’ capacity to produce electricity from geothermal energy. In the summer of 2011, the U.S. Congress approved $70 million in funding to research geothermal energy.

It’s not just the government getting in on the act, either. Some contractors report anecdotally that over the past five years or so, demand from customers for geothermal heating installations has risen noticeably.

What’s all the fuss about? Well, for starters, geothermal heating can lower heating costs dramatically by reducing reliance on electric or fuel-based heat. Anyone that has received a staggeringly high home heating bill knows that any relief would be welcome.

Additionally, geothermal heating has the advantage of being hidden from sight. Unlike solar panels that have to be mounted on your home or a towering windmill that dominates your property, geothermal pipes run underground. Once they’re installed, no one even knows they’re there.

Geothermal may not be for everyone, but if you are looking for an alternative energy solution in Bethesda, you have some land and you can invest some money upfront to see savings each month, then it might just be for you.

The Benefits of Ductless Splits AC in Gaithersburg

Monday, April 23rd, 2012

Ductless splits air conditioners are designed to eliminate the need for ductwork in a home where space is at a premium. Usually homeowners with older homes – those built before the 1970s – have very little space to work with when it comes to installing the ductwork a traditional central air conditioning system requires. These homes are often heated with radiant boiler systems and have window units to provide cooling in warmer weather. As a result, cooling costs can be extremely high each summer and the house usually isn’t comfortable during these months.

Ductless air conditioning offers a solution to most of these problems. Not only does the technology not require ductwork to be installed; it allows for multiple in-room units on a single compressor and it costs significantly less to operate compared to window AC units.

Ductless System Specifications

Ductless air conditioning systems consist of two major components: a compressor which is placed outside and indoor evaporators. With the use of inverter technology, these systems can support multiple evaporators – usually as many as four to a single condenser. This means you can have a single outdoor unit supporting cooling four separate rooms of your home at the same time.

Each of those indoor evaporators acts as a heat pump, allowing you to both heat and cool the room year round. And because the only connection needed between evaporator and condenser is a single refrigerant line, the installation is much simpler than it would be for a ductwork based central AC system.

Room by Room Benefits

While the primary benefit of a ductless system is the fact that it allows you to install air conditioning in multiple rooms of your house without the need for ductwork, there are other benefits. Not only do you get a much higher energy efficiency rating than you would with traditional window units (many ductless systems are rated at 16 SEER or higher while window units are frequently as low as 10 or 11), but you can control each unit individually. So if a room upstairs doesn’t need to be cooled during the afternoon hours, simply turn off the thermostat in that part of the house and save money.

There are some factors to consider when installing a ductless system. How many rooms do you need cooled? How warm does it get in the summer? Will the system be used for heating in the winter? These are all things you may want to discuss in greater detail with your contractor when you call for an estimate.

Air Conditioning Repair Tip: The Danger of Refrigerant Leaks

Monday, April 16th, 2012

Your air conditioner is filled with a chemical compound called refrigerant. This substance is what allows your air conditioner to remove heat from and dehumidify your home. It is a necessity, but it is also a dangerous chemical that, if released, can cause damage to the environment and pose health risks to your family.

 Why Refrigerant Is Dangerous

There are many types of refrigerant but most air conditioners use either R-22 or Freon coolant – depending on their age. Newer air conditioners may use R410-A refrigerant, an environmentally safer alternative.

All of these refrigerant types are chlorofluorocarbons or CFCs. These chemicals are controlled substances by the Environmental Protection Agency, meaning they must be properly removed and disposed of. Because your air conditioner does not consume any of coolant in operation, it should never need to be refilled unless there is a leak. Such a leak should be stopped immediately due to the immense damage CFCs can do to the environment.

If you suspect a leak, you should call a Bethesda air conditioning professional immediately to inspect your air conditioner.

 Damage to Your Air Conditioner

Beyond the environmental and health issues posed by a refrigerant leak, the biggest problem you will face is damage such leaks can cause to your air conditioner. Low refrigerant levels put undue stress on your compressor and can lead to damage in almost every part of the device.

Not only that but the air conditioner won’t work as efficiently. A 10% loss in refrigerant volume can result in up to a 20% increase in electricity cost to run your air conditioner.

 What to Do in the Event of a Refrigerant Leak

If you suspect a refrigerant leak in your air conditioner, take action immediately. Call a certified Bethesda HVAC technician who can recapture the escaped gasses and seal the leak fast. It is important not just for your safety but for the wellbeing of the environment.

Air Conditioning Question: Why Are Clean Filters So Important for Efficiency?

Monday, April 9th, 2012

Your air conditioner cost money to operate – even more when they don’t work at 100% efficiency. So, it is important to perform the various regular maintenance tasks that ensure the system uses as little electricity as possible. The first thing on your list (and the easiest) is cleaning those filters.

Keeping Filters Clean

Did you know that you can lower your air conditioner’s energy use by up to 15 percent by just keeping your filters clean? While that might seem surprising, it actually makes a lot of sense when you consider how the filter works.

The filter on your AC captures dust and debris that is circulated through your system. If you didn’t have a filter at all, the dust and dirt would not only cause problems with some of the mechanical parts of your AC but also reduce your indoor air quality. However, when a filter is clogged, your HVAC system has to work harder to draw air in. Your motor will need more electricity for the same amount of cooling.

It takes very little to clog the filter of an AC unit, especially if it is running 24 hours a day for two or three months out of the year. So, it’s best to check your filters once every 30 days regardless of what type of filter you are using.

Which Filters to Check

The main filter on your AC unit should be checked along with any air handler filters and any air cleaner filters you have installed in your system. Another thing to consider is the condition of your home and the area around your outdoor condenser. If you have pets, lots of plants or your condenser is located in a dusty area, you may need to check and change those filters even more often.

Most filters are located along the return length of the ductwork – sometimes in ceiling ducts and walls, though they may also be located in your furnace’s air handler or inside the air conditioning unit. If you have window units or mini splits, the filters are frequently in the unit.

Clean air filters are important for your health, your wallet and the longevity of your AC system. Stay on top of them and you will save money in more ways than you might expect.

Your Frederick HVAC System and Ventilation

Monday, April 2nd, 2012

The vent system in your home is vital to the operation of your Frederick HVAC system. Without successful ventilation, your home won’t have the necessary clean air to keep you and your family healthy. So, what does proper ventilation require and how can you ensure your home has it? Here are some quick tips.

Install the Right Parts from the Start

Proper ventilation should result in even air pressure in your home to avoid problems with gas pilot lights. It should also be as energy efficient as possible and provide clean air through proper filtration and cleaning of the air that comes in. The best way to ensure your home has the ventilation needed to stay comfortable and safe for your entire family is to check the total size of the home and then measure the concentrations of certain pollutants like dander, pollen and smoke. A Frederick air conditioning contractor can provide these services for you. Frederick HVAC Installation

Energy Loss

Ventilation is very important, but it is also important to remember energy loss. Since ventilation obviously involves moving air in and out of your house, you lose some of conditioned air that your is produced by your furnace or air conditioner, which makes them work harder to maintain the temperature.

To solve this problem, you should think about getting an energy recovery ventilator. Energy recovery ventilators transfer heat from one environment to another, so you are able to get fresh air into your home without worrying about raising your utility bills. In the winter, it transfers the heat to from the air going out to the air going in, and in the summer it will do the opposite. Its an excellent way to get great indoor air quality without putting extra strain on your HVAC system.

Supplements to Ventilation

Proper ventilation should not only provide fresh air, but it should also ensure your home has clean air. The air outside may be fresher, but it can be filled with pollutants like pollen, dander and smoke. These should be removed before they get inside and into the lungs of your loved ones. To do this, you need a full sized air cleaning system that removes particles from the air down to 0.3 microns.

HEPA filters can do this, as will electronic air cleaners which can ionize and remove smoke and gas particles. Make sure you discuss filtration and cleaning with Tuckers Air Conditioning & Heating during your next annual maintenance visit.

Heat Pump Question: Why Won’t My Heat Pump Start?

Thursday, March 29th, 2012

If you are having trouble with your Germantown heating system, or more specifically your heat pump, you may be surprised to learn that it is probably not the heat pump that is to blame.  That seems counterintuitive, but it’s true: the heat pump can be in perfect working order but still not turn on.

The good news, then, is that your heat pump is fine and you won’t have to pay an arm and a leg to fix or replace it. Still though, these types of problems can very frustrating to diagnose and correct. There are four common culprits when a heat pump won’t start.

  • A common problem is no power to your Germantown heat pump, which is certainly going to cause it to stop working. You should check your breaker box to make sure that the circuit breaker was not tripped. If your heat pump is wired to a switch, check to see if that switch is turned on. While this might seem obvious, its an important first step to take when troubleshooting.
  • Another quick check any homeowner can make is to see if the heat pump is set to the right mode. You want ‘heat’ mode on during the winter and ‘cool’ mode on for the summer. Again, this might seem obvious, but you should always check the mode before deciding that your heat pump needs a professional repair.
  • If you have recently replaced your home’s thermostat, it might not be communicating properly with your heat pump. Some thermostats don’t work well with heat pumps, so you should always check the model’s compatibility before installation. Incorrect wiring may also cause a problem. While you probably need a professional to fix this issue, it is relatively simple to resolve.
  • The last problem that commonly occurs is the heat pump’s own circuit breaker is tripped. Check your unit to see if your unit has its own circuit breaker to determine if that is the problem.

If you exhaust these problems and the problem persists or recurs – for example, if the circuit breaker trips again – call a Germantown heating and air conditioning contractor to work on your heat pump. There may be something larger at work that is causing problems in the electrical system that controls your heat pump, and that requires some expertise to properly address.
