Top 5 Tips to Save Money on Heat Pump Replacement

Monday, June 5th, 2017

Heat pumps are vital components of your entire cooling, heating, and ventilation system. They use advanced air transfer methods to move warm air out of your home during the hot months, leaving cool air behind indoors, and move warmth from the outdoors into your home during the cold months. Rather than generating artificial temperatures, a heat pump simply moves cool and warm air around to create comfortable temperatures.

What Corrosion on a Heat Pump’s Coils Means

Monday, February 24th, 2014

Heat pumps make a logical and economical solution for both heating and air conditioning here in Atlanta. They function well in conjunction with our mild winters. Heat pump problems are infrequent, but then they do occur, they can often be serious. Take the issue of rust or corrosion on the internal components, especially the coils. Here’s a brief discussion of what corrosion on a heat pump’s coils means.

Corrosion comes in many forms; it is usually caused by exposure to cleaning products with a high acidic content, fluoride in the water, or similar elements.  High quality heat pumps will apply a protective coating to their coils, but that can wear out over time.

Regardless, the corrosion itself is a serious problem. Over time, it with create a breach in the coil, releasing refrigerant gas and effectively halting the heat pump’s ability to function. When that happens, the coil will need to be replaced if you want the heat pump to function again.

You can help prevent this first by having a professional coat the coil in a corrosive retardant that will help protect it. A qualified professional can assess the state of your coil, then make a recommendation for a reliable coating based on the particular needs of your heat pump. You can also schedule regular maintenance sessions to watch for signs of corrosion and perhaps alter the existing conditions to reduce the risks involve (such as removing problematic insulation from the wall around the heat pump).

In these cases, the experts at Cool Air Mechanical are ready to help you. We know what corrosion on a heat pump’s coils means and we would much rather help you prevent the problem before it becomes too big to handle. Here in Atlanta, heat pump repair services like ours are ready and able to set up a maintenance session or a flat-out repair session to keep your coil rust-free.

3 Things to Consider Before Your Heat Pump Installation

Monday, February 17th, 2014

Heat pumps are an innovative and versatile means of conditioning the air in your house. They utilize the same basic system as an air conditioner, which cycles refrigerant gas through a series of valves and coils to change the temperature in the surrounding air. But while air conditioners are set up to simply cool your home, heat pumps can use the same system to reverse the process and heat it as well. They work best in areas with mild winters, which is why Atlanta heat pump installation makes a lot of sense. If you’re thinking about placing a heat pump system in your home, you want to prepare for the operation properly.

Here are 3 things to consider before your heat pump installation:

  • Ducted or Ductless: Some heat pump are forced air systems, designed to work in conjunction with a duct system. Others work as part of a ductless system, deploying multiple indoor units throughout your house to heat or cool each space individually. Which one works best depends on the specifics of you house. If you have an existing duct system, a centralized heat pump might work best. If you don’t, then you might want to look into a ductless heat pump system.
  • Sizing is key: Like other HVAC systems, heat pumps need to generate just the right amount of power to work best. If it’s too small, it won’t heat or cool your home adequately. If it’s too large, it will cycle on and off rapidly, wasting considerable energy in the process. A technician can inspect your home and provide a precise estimate of the right sized heat pump for your space.
  • Select locations carefully: Heat pumps depend on both indoor and outdoor components to do their job. You’ll need to find spots in the right location (or locations) in your house and make sure they have the right dimension for the unit. Heat pumps do make some noise, so that might affect the placement of your unit as well.

The experts at Cool Air Mechanical can help with Atlanta heat pump installation, as well as giving you more things to consider before your heat pump installation begins. Careful planning is the key to installing a new heating system, and we have the expertise to do the job right. Call us today to set up an appointment!

Are Heat Pumps Cost Effective?

Friday, January 10th, 2014

Heat pumps combine the functions of an air conditioning system and a heater into one unit. Heat pumps are an excellent heating system for Marietta, since they do best in places with mild winters. But are heat pumps cost effective? According to the U.S. Department of Energy they are: saving you up to 40% in monthly costs depending on your old heating system. A closer look at how it works can explain the reasons why.

In simple terms, heat pumps don’t strictly create heat. They simply move heat around, which uses a lot less energy than an electric or gas furnace. The refrigerant in the heat pump transfers heat from the inside to the outside or visa versa, instead of creating heat by burning a fuel. The process involves a little electricity, but not nearly as much as you’d need with an electric heater.

The technology works best when heating in Marietta and similar communities, where the temperature rarely drops below a certain level. Heat pump efficiency tends to drop when the temperature falls to 40 degrees or below. It struggles below that, though you can augment its heating ability with an electrical or gas furnace.  Thankfully, that’s less of a problem here in the Atlanta area, which helps make heat pumps cost effective as well as convenient.

Contact Cool Air Mechanical to see if a heat pump is right for your home; we can explain the detail to you and help you find a model that suits your needs. We can explain the details to you and conduct installation while keeping you in the loop every step of the way. Give us a call today to set up an appointment!

Benefits of Dual Fuel Systems

Wednesday, December 18th, 2013

Heat pumps are popular options for home comfort in Georgia; we often recommend them to our clients because of their energy-efficiency and double function as both a heater and an air conditioner.

However, heat pumps do have one drawback that sometimes makes homeowners hesitate about installing them: they begin to lose their heating efficiency in when the outdoor temperature drops below freezing. This is where dual fuel systems come in so handy. We’ll explain what a dual fuel system does and how it can benefit your heating in Marietta, GA.

For installation of a dual fuel system, or repairs and maintenance on an existing one, contact the experts at Cool Air Mechanical—24 hours a day, 7 days a week.

What a dual fuel system can do for you

A dual fuel system is a hybrid of a heat pump and a second heater that uses a different fuel source. Usually, the second heater is a gas furnace. The back-up heater will activate when the outdoor temperature drops below the “economic balance point,” i.e. the point at which the heat pump will start struggling to reach its target temperature.

The first benefit of a dual fuel system is that you will have all the advantages of a heat pump—its use as both a heater and an air conditioner, its energy efficiency—without the main disadvantage.

The second benefit is that you will not experience high heating bills because of the back-up system. The back-up heater will need to run only a few times during the winter (especially a mild Georgia winter), so the increase in your energy bills over the heat pump working alone will not be significant. You’ll have the warmth of a furnace without the full price of running a furnace.

The third benefit is that the system is automated. You don’t have to think about the back-up heater at all, because it will come on when it needs to and then shut off when the heat pump no longer needs it.

Dual fuel system repairs and maintenance

Because dual fuel systems add a layer of complexity to a heat pump, they require professional repairs when anything goes awry with them. Sometimes a heat pump can lose its connection to the back-up system, and trained technicians can easily repair this and restore the full heating power of the system. You’ll also need expert technicians to maintain both your heat pump and the second system so they will work up to their full potential each winter.

For heating in Marietta, GA, a dual fuel system is a great option if you have concerns about low temperatures. Contact home heating professionals like those at Cool Air Mechanical and schedule an appointment to see if installing a dual fuel system will work for you this coming winter.

If the Air Is Chilly, How Can a Heat Pump Heat?

Friday, December 13th, 2013

Heat pumps are marvelous devices for keeping a home comfortable year round. But how exactly does a heat pump both heat and cool? Even when people know a bit more about the process of heat exchange that allows a heat pump to perform these two different tasks, they still feel puzzled about how heat pumps function during cold weather.

We’ll explain in a bit more depth in this post how heat pumps provide heat during the cold weather, even when they have to extract heat from the chilly outdoors. If you need repair, installation, or maintenance for a heat pump in Atlanta, GA, contact our skilled technicians at Cool Air Mechanical.

Heat pump operation: heat from the cold air

Here are the basics of how a heat pump works: using refrigerant that cycles through it in a closed loop, a heat pump moves heat from one location (the indoor unit or the outdoor unit) and moves it to another. This is called heat exchange, and the heat pump uses the air as its heat exchange medium. During hot weather, a heat pump acts as an air conditioner, taking heat from inside a home and moving it to the outside. Then, during colder weather, it moves heat from outdoors and brings it indoors.

And that’s where people become confused. Where is this heat coming from if the outside is already cold?

Although it may be hard to believe when you’re standing outdoors on a chilly day, there is still heat in cold air. As long as there is some molecular motion, there is heat available. (Absolute zero, the point of no molecular motion, is only a theoretical temperature.) Using evaporation along the outdoor coil, a heat pump absorbs some of this available heat and brings it indoors.

However, there is less heat outdoors in lower temperatures, which leads to one of the few drawbacks of a heat pump: they perform less effectively in extreme low temperatures. Once the thermometer drops below freezing, heat pumps will struggle with efficient performance. To balance this, some homeowners have a dual fuel hybrid system installed, where a second heating system (such as propane-powered furnace) comes on when the heat pump can no longer handle the low temperature.

Fortunately, Atlanta weather rarely plunges to temperatures where a heat pump will struggle, which makes them ideal for our city. Cool Air Mechanical can install a heat pump—or a dual fuel hybrid system if you need it—in your home to give you fantastic year-round comfort.
