Repairs a Heat Pump May Need in Winter

Wednesday, October 29th, 2014

The best reason to have a heat pump installed for your home is that you receive two comfort systems in one unit: a forced-air heater and an air conditioner. In a place like Connecticut, which enjoys the full range of seasons, you will receive plenty of activity from both modes of a heat pump. This means the system will undergo a great deal of stress over the year, and it’s important to schedule twice-yearly maintenance to make sure that it remains in the best shape and rarely require repairs.

But malfunctions can still happen, and you’ll need to call expert repair technicians to solve them. The repair staff at Dynamic Mechanical Heating & Air Conditioning is ready around the clock to help you fix your heat pump, no matter the time of year. Whatever heating repair in Berlin, CT you need, we can deliver it.

Heat Pump Winter Time Blues: Some Repairs Issues You Might Encounter

Because a heat pump works in the same fashion whether in heating or cooling mode (it circulates refrigerant from the inside to the outside of a house, moving heat from one location to the other), you should not expect problems when turning the system from cooling mode to heating mode when the winter weather arrives. However, there’s a chance that a malfunction developed in the reversing valve during the summer and you didn’t notice it. The reversing valve is a critical component that makes a heat pump different from an air conditioner: it changes the direction of refrigerant flow and allows the heat pump to switch from removing heat from the inside of a home (cooling mode) to removing heat from the outside of a home (heating mode). If the valve breaks or loses its connection to the thermostat, you will end up with a heat pump that will only send cold air—when you want warm air!

Technicians will usually need to change out the reversing valve entirely. This is complex repair, and isn’t something you can attempt on your own by opening up the heat pump cabinet. If your heat pump is locked in cooling mode when winter starts, call for skilled repairs.

Something else to watch for when winter begins is dirt along the outdoor coil. When the heat pump moves into heating mode, this coil begins to work as the evaporator coil, absorbing heat. Dirt along the coil that may have developed over the summer will make the coil struggle with sufficient heat absorption, leaving the refrigerant inside it too cold. This will cause the coil to begin to ice over. (A similar problem can occur with the indoor coil in cooling mode.) This is a serious issue, and should you notice ice on the outdoor coil, call right away for professionals to remove, defrost, and clean the coil. Ice on the coil might also point to other serious malfunctions, such as leaking refrigerant, and it needs to be dealt with as soon as possible.

How a Hybrid Heating System Protects Your Comfort

Wednesday, October 22nd, 2014

Heat pumps can be great systems for many households, but there is concern about using a heat pump during the winter, particularly in the Northeast. The reason for the concern is valid: heat pumps absorb the heat around them to provide heat to your home; because of this, they can struggle when the temperature goes below 32 degrees, as it does frequently in Connecticut. So how can you enjoy the benefits of a heat pump while also have adequate heating in Farmington? Consider installing a hybrid heating system. A hybrid heating system uses a heat pump as its main source for heating (and cooling), while also having a gas furnace back-up. A hybrid system can be complex, so it’s important to hire professionals, like the ones at Dynamic Mechanical Heating & Air Conditioning, for installation.

Protecting Your Comfort

As stated above, a hybrid system uses a heat pump as the main source of heating, and has a gas furnace as a back-up system. The switch is automatic, and happens via the use of a dual-fuel thermostat and a sensor that is placed on the outdoor unit. As the owner, you set a temperature for the sensor that signals the system to change from the heat pump to the gas furnace for heating. Once this set-point is programmed, the system will automatically switch from using the heat pump to using the gas furnace at this set temperature. You’ll also set a temperature at which the system can go back to using the heat pump as its main source for heat. This feature allows you to have total comfort without having to worry about how cold it is outside.

With a hybrid heating system, you can enjoy the many benefits of a heat pump, including:

  • Heating and cooling
  • Excellent energy efficiency
  • Longer lifespan of equipment
  • Comfortable, gradual heating and cooling

If you are worried that a heat pump system won’t work for you because of winter temperatures, you don’t have to worry anymore. A hybrid heating system in Farmington can give you the heat pump you want with the assurance of gas heat should you need it during the winter. Call Dynamic Mechanical Heating & Air Conditioning today and schedule an appointment with one of our installation experts.

Common Misunderstandings about Boilers

Wednesday, October 15th, 2014

Boilers have a number of common misunderstandings circulating about them. Most of these are due to the fact that boilers operate so differently from furnaces, which are more familiar to homeowners. Below we’ll examine some of the common myths and misconceptions commonly applied to boilers.

Myth: Old Boilers that Start “Kettling” May Explode

Kettling is what happens when too much water becomes trapped in the boiler, usually from mineral deposits blocking the lines out. This can lead to banging and gurgling sounds coming from the boiler when it is running. This usually happens with old boilers, as it takes time for the mineral deposits to build up in the chamber. While boilers do occasionally explode, this is an extremely rare occurrence that usually is the result of other factors. If your boiler is kettling, call a professional to fix it. You don’t need to live in fear of an exploding boiler, however.

Myth: Gas Burning Boilers are More Energy Efficient than other Kinds

Not really. The energy efficiency of most heating systems depends less on the fuel they burn and more on the internal operation of the actual unit. There are efficient wood and oil boilers, as well as extremely inefficient gas boilers. Now, you will have to store things like oil, wood, and propane to fuel your boiler. Natural gas can simply be piped in by the city. Don’t let that fool you into thinking that natural gas is always the best option, however.

Myth: Boilers are More Difficult to Install than Furnaces

Not true at all. Boilers require a different system to be installed, but are in no way more difficult to install than furnaces. This is especially true if you are installing a boiler system in a new house. Retrofitting will, of course, be more expensive than installing a unit for which the house is already equipped. This is true of all systems, however, and not just of boilers.

If you want to know more about boilers, or are thinking of having one installed, call Dynamic Mechanical Heating & Air Conditioning and schedule an appointment. We install boilers all over the Burlington, CT area.

Gas Furnace vs. Electric Furnace: Your Heating Options

Wednesday, October 8th, 2014

When it comes to furnaces, homeowners have a few choices in fuel types. Two of these choices are electricity and gas. Electric furnaces have come a long way over the years, and have proven to be a good choice for certain homes. But no matter which furnace you choose, make sure that you hire professionals for your furnace installation service in Wethersfield. Dynamic Mechanical Heating & Air Conditioning has helped multiple customers in the Wethersfield area choose and install heating systems, and we can help you from start to finish.

Electric Furnaces

As we mentioned above, electric furnaces have come a long way over the years, especially where energy efficiency is concerned. Electric furnaces heat by blowing the air heated by red-hot metal coils through ductwork. There are several benefits to installing an electric furnace that make them worth considering for certain households:

  • Good energy efficiency – because electric furnaces do not use a fossil fuel, they have an average AFUE rating of 95% and can go as high as 100%.
  • Long lifespan – the average life of an electric furnace is 20 to 30 years.
  • Lower installation costs – the cost for purchasing and installing an electric furnace can be more the 40% less than that of a gas furnace.
  • No need for a gas line or fuel tank – some homes do not have access to a natural gas line, and it may not be convenient to install a fuel tank.

Gas Furnaces

Gas furnaces are one of the most commonly-installed heating systems around. Using natural gas, gas furnaces heat air with a heat exchanger, and then blow the hot air into your living spaces. There are several benefits of gas furnaces worth considering:

  • Gas is usually less expensive – natural gas is less expensive to use as a fuel than electricity.
  • Gas heat is very effective – gas heat is around 130 degrees, and will heat your home faster than an electric system; this also makes gas furnaces more effective on very cold days.
  • Clean burning – natural gas is the cleanest burning of all the fossil fuels.

Choosing a heating system in Wethersfield is a big decision. If you need help deciding what type of furnace is the best fit for your home, call Dynamic Mechanical Heating & Air Conditioning today and schedule an appointment with one of our experts.

How Does a Heat Pump Provide Both Heating and Cooling?

Wednesday, October 1st, 2014

Heat pumps are pretty ingenious devices, as they provide both heating and cooling, and use very little energy to do so. But the name “heat pump” can be confusing, leaving a homeowner to wonder how this device can both heat and cool a home. We’ll explain more about this below, but one of the most important things to keep in mind about heat pumps in Bristol is that. if you are considering the installation of one, or need repair or replacement, you should always hire experts. Dynamic Mechanical Heating & Air Conditioning has been installing, repairing, maintaining and replacing heat pumps for almost a decade, and we bring this experience to every job.

How Do Heat Pumps Heat and Cool?

Heat pumps can both heat and cool because they are made with a component called a reversing valve. This valve allows the heat pump to change the flow of refrigerant in the system, so it can operate in either cooling or heating mode. During the winter, in heating mode, the heat pump absorbs heat from the surrounding air, concentrates it in the heat exchanger and blows the air into your home. In the summer months, the heat pump removes the heat and humidity from your indoor air and transfers it to the outside. A heat pump doesn’t create heating or cooling; it simply transfers heat from one place to another, with the help of refrigerant. Heat pumps do not use fossil fuels, and use about 25% of the amount of electricity of a whole-home air conditioning system.

Other Benefits of Heat Pumps

Heat pumps also offer other benefits aside from being able to heat and cool your home:

  • Very “green” – as we mentioned above, heat pumps use no fossil fuels and very little electricity, making them very environmentally friendly.
  • Very comfortable heating and cooling – heat pumps operate at a low, continuous airflow, so the heating and cooling is gentle and comfortable.
  • Long lifespan – heat pumps have an average lifespan of 20-25 years, as compared to 10-12 for air conditioners and 15-20 for heating systems.

Heat pumps can be a great option for your home, but the best way to determine if a heat pump is a good choice for you is to work with a trained specialist. Call Dynamic Mechanical Heating & Air Conditioning and schedule an appointment with one of our experts to see if a heat pump for your Bristol home is right for you.
