Understanding Your Heat Pump: Compressor Problems

Monday, March 3rd, 2014

Heat pumps make a viable and cost-effective alternative to more traditional heating and cooling systems. They work according to the same principles as air conditioners, transforming refrigerant gas into a liquid (releasing heat into the surrounding air) then returning it to gaseous form with an evaporator coil (absorbing heat from the air). In the summer, they absorb heat from inside your home and transfer it outside, and in the winter they absorb heat from the outside and use it to heat your home. Heat pumps work best in places with mild winters, making them ideal for the Tampa Bay area. It can help you know when to call for repairs if you have some understanding of your heat pump: compressor problems, for example, can be quite tricky, and knowing how to spot the signs will help you facilitate repairs that much more quickly.

Here is a brief list of the most common compressor problems:

  • Frequent cycling. If electrical problems develop in the compressor, it can lead the heat pump to turn on and off very quickly multiple times throughout the day. Heat pumps and air conditioners use the most amount of power when they start up and turn off, which means you want them to run for at least 15 minutes every time in order to prevent wasteful energy.
  • Lost heating or cooling capacity. The compressor relies on specific system pressure to do its job. If that pressure isn’t what it’s supposed to be – if there’s a leak or similar problems – with will interfere with the heating and cooling process, reducing the unit’s overall efficiency.
  • The compressor won’t start. If the compressor motor is faulty, it won’t start. In most cases, that means that the heat pump itself will simply won’t function. Your fan may still run, but the air coming out of the vents won’t be the right temperature.

Understanding your heat pump means spotting compressor problems as well as malfunctions in other parts of the system. If you notice an issue with your heat pump in Tampa, call the experts at Ierna’s Heating & Cooling. Our trained staff will get to the bottom of the problem quickly and correct it with professionalism and efficiency. Call us today to make an appointment!

How Poor Heat Pump Installation Leads to Heating Repair

Monday, February 10th, 2014

While it might be tempting to hire the least expensive contractor you can find, but it’s important to make sure that your technician is properly licensed and trained to work with your system. One of the main reasons that heat pump installation should remain out of the hands of amateurs is that a poor installing job will lead to numerous heating repair needs. The money you believe you’ll save with amateur installers will end up going into years of repair work. Instead of going this route, start off right and call Ierna’s Heating & Cooling for heat pump installation.

Heating Repair Issues from Poor Installation

Probably the most common problem that can arise from a shoddy installation job is from leaky connections between the indoor cabinet and the ductwork. The ducts must maintain a tight seal with the cabinet at all times or it will result in a plunge in air pressure. The ducts will to be repaired, sealed, and sometimes rebuilt around the heat pump to allow them to fit correctly.

Low refrigerant is another issue that happens because a heat pump was installed incorrectly. There’s a good chance the installers put in too little refrigerant or put in the wrong refrigerant blend. Other installation mistakes can lead to leaking around the seals where the refrigerant lines connect to other components. A loss of refrigerant is a serious problem that will lead to icing over the coils and a drop in efficiency eventually causing a total loss of heating and cooling power unless it is fixed.

Amateur installers will often create faulty connections from the heat pump to the power supply (causing tripped circuit breakers) as well as to thermostat (resulting in uneven temperatures or the heat pump refusing to come on when it should). Extensive electrical repair is usually required to fix this.

Make sure you have licensed professionals on the job from the beginning of the installation process, so you will have the right heater, at the right size, fixed up so it will run with as few problems as possible.

But even with the finest installation possible, a heat pump may eventually need repair work. Ierna’s Heating & Cooling has you covered there as well: we have NATE-certified technicians ready for your heating repair in Tampa, FL, any time of the day or night.

The Refrigerant in Your Heat Pump: What You Need to Know

Monday, January 6th, 2014

Heat pumps are impressive heating and cooling systems, and ones which are gaining popularity across many parts of the US. Heat pumps work just like your central air conditioner, yet can provide heat to keep your home comfortable all winter long.

The way a heat pump does both of its jobs is through a chemical compound called refrigerant. In this post, we’ll explain a bit more about what refrigerant is, how it allows the heat pump to do its job, and a few things to watch out for. Taking care of trouble with refrigerant requires the work of skilled technicians, so rely on a company like Ierna’s Heating & Cooling for help with your heat pump in Tampa, FL.

Refrigerant basics

Refrigerant is a chemical compound—the different types are called “blends”—that requires only a small amount of energy to change from a liquid to a gas and back again. The earliest systems used chemicals that were either toxic or flammable, but modern heat pumps use safe blends referred to by the general name “Freon” (a trademark of DuPont). The main blend used today is R410A and is replacing an earlier blend, R22.

Refrigerant is responsible for the movement of heat from one set of coils in the heat pump to another; this is the process called heat exchange that allows a heat pump to warm your house during the winter (the refrigerant absorbs heat from the outdoor coils, releases it to the indoor coils) and cool it during the summer (the refrigerant absorbs heat from the inside coils, and releases it to the outdoor coils).

Refrigerant does not dissipate during normal operation of the heat pump. The refrigerant remains at the same level—its “charge”—as it changes between liquid and gas states. However, leaks can sometimes develop in heat pumps from corrosion, loose connections, or damage, resulting in a loss of refrigerant. When this occurs, a heat pump will start to develop icing over its coils and lose its ability to provide conditioned air.

It requires the work of a trained technician to find and seal refrigerant leaks, and then recharge the refrigerant to its regular level.

Don’t let refrigerant problems take away the great advantages of a heat pump in Tampa, FL! Call Ierna’s Heating & Cooling day or night for heat pump and AC repair service.

Heating Systems for the Land O’ Lakes Area

Monday, November 12th, 2012

When you live in a warm climate such as the Land O’ Lakes area you may think that an effective home heating system is not a priority. Fact of the matter is, though, that even in warmer climates a dependable home heating system is necessary to ensure your year round comfort. When the temperature drops the memory of the hot, sunny days of summer won’t keep you warm. That being said, there are some good heating options for such warm climates that Ierna’s Heating & Cooling would like to tell you about. If you think that a gas furnace is unnecessary for your Land O’ Lakes area home, consider the following systems for installation. Both offer the benefit of providing both heating and cooling power as well as innovative design and efficient performance. Contact Ierna’s with any further questions that you may have or to schedule installation service.

Heat Pumps

If you are looking for an efficient, environmentally friendly way to both heat and cool your home with one convenient system a high quality heat pump may be the best choice for you. Ierna’s Heating & Cooling offers heat pumps from such trusted manufacturers as Bryant and has years of experiencing with the installation, maintenance and repair of these systems. When you live in an area such as Land O’ Lakes that does not have harsh winter conditions a heat pump is a great home heating option.

Heat pumps, unlike more traditional heating systems, do not consume a fuel source in order to heat your home. Rather they operate according to the heat transfer principle, using just a small amount of electricity to transfer existing heat into your home. By using this ambient heat, heat pumps are able to greatly reduce the amount of energy that you use when heating your home, in turn lowering the amount of money that you pay in heating costs. Plus, a heat pump’s operation is easily reversed, meaning that in the hot summer months it will remove excess heat from your home in order to cool it.

Ductless Mini Splits

Ductless mini splits are another great way to heat your home in a warmer climate. They too offer both heating and air conditioning, making them convenient for year round use. Because these systems do not use ductwork to circulate air throughout your home they are not subject to the energy loss sometimes associated with ductwork. They feature individual air handlers in different rooms of your home, allowing for easy, convenient zone control. This helps you to heat and air condition your home in a more efficient, effective manner.

If you have any questions about these innovative home heating options call the pros at Ierna’s Heating & Cooling. We’ll be glad to share our expertise with you.

Heat Pump Guide: Benefits of Installing a New Heat Pump

Monday, October 22nd, 2012

If operating your Land O’ Lakes home’s heating or air conditioning system causes you concern about utility costs or environmental impact you may want to consider the installation of a new heat pump. Heat pumps offer you the ability to both heat and cool your home in an efficient, eco-friendly way. Here is some basic information about heat pumps from the Land O’ Lakes heating and air conditioning professionals at Ierna’s Heating and Cooling.

How a Heat Pump Works

Heat pumps work on the principle of heat transfer. This means that, rather than consume a fuel to create energy, they absorb ambient heat from the air, water or ground surrounding your home for use inside. Only a small amount of electricity is used in the heat transfer process, meaning that energy use is greatly reduced and utility bills along with it. The process is easily reversed, too, so you can use your heat pump to transfer heat outdoors from your home when temperatures are high.

Types of Heat Pumps

There are few different types of heat pumps. Air-source heat pumps absorb heat from the air for use in your home or transferal out of your home. Water source heat pumps take energy from or return it to the ground or water on your property. There are a number of factors to take into consideration before having any type of heat pump installed on your property. Not all types of heat pump installations may be available in your area, so be sure to do your research before deciding which is right for you.

Offset Purchase and Installation Costs

An air source heat pump installation from a qualified service provider such as Ierna’s Heating and Cooling  is a great choice for many homes. It all comes down to efficiency. A high-efficiency furnace will cost more than a lower efficiency model, and the same is true of home comfort systems in general. The fact of the matter is that you can offset the initial costs of your heat pump heating and cooling system by reducing energy consumption.

When you’re ready to start exploring your heat pump options, call the professionals at Ierna’s Heating and Cooling. We’ll help you decide if a heat pump is right for your Land O’ Lakes home.

AC Tip: Using Heat Pumps for Air Conditioning

Monday, August 13th, 2012

In addition to providing your Tampa home with energy efficient heating, heat pumps can also keep you home cool by reversing its operation process. Heat pumps transfer warm air indoors to heat your home, and can also transfer that warm air out to cool it.  Heat pumps actually function very similarly to a central air conditioning system when they are in cooling mode.

During the air conditioning process, a heat pump pulls cold temperatures from the air while hotter air from indoors is transferred outdoors.

Heat pumps are highly energy-efficient, particularly during colder months when the heat pump is being used to heat indoor air.  Heat pumps use quite a bit less energy to run them than other heating systems, ranging anywhere from 8 to 10 HSPF. This is well above the 7.7 HSPF minimum required.  During the air conditioning cycle, heat pumps are still very energy-efficient, ranging anywhere from 14 to 18 SEER, which is well above the minimum 13 SEER that is required.

Heat pumps are smaller than many other home heating and cooling options, and because they are installed outside they save interior space.  They are also known for their easy installation, fewer repair needs, and less expensive maintenance.

So when you are looking for a single option that will both heat and cool your indoor air with ease while being energy-efficient and offering a variety of benefits, a heat pump may just be the right choice.  Let our well-trained Tampa air conditioning technicians answer any additional questions you may have about heat pumps, and also provide you with excellent heat pump installation services. We have the training and experience necessary to help you get the most out of your heat pump. Call Ierna’s Heating & Cooling today!

Tampa HVAC Question: What is a Heat Pump Reversing Valve?

Monday, July 23rd, 2012

Did you know that heat pumps can be used for both heating and cooling in your Tampa home? The reversing valve is what makes this possible, read on to learn more!

In General

Functioning on the same principle as refrigerators, the heat pump uses a liquid to absorb heat as it turns into a gas and release heat as it returns to a liquid state. During the summer, the heat pump operates as a standard central air conditioner, removing heat from the house and venting it to the outside.

In the winter, the heat pump reverses this process, extracting heat from the cold air outside and releasing it inside the house. The heat pump is very efficient when the outside temperature is around 45 degrees Fahrenheit to 50 degrees Fahrenheit, but it becomes less efficient as the temperature drops.

The Heart of the Matter

The reversing valve in the heat pump switches the process from absorbing heat from the inside to evacuate outdoors like an air conditioner to extracting heat from cold temperatures outside and redistributing it indoors.  The thermal energy at play is the natural force of heat to move toward cooler temperatures, releasing energy in the shift.  Heat pumps take care of both and the reversing valve controls the direction of the flow.

The reversing valve has two states of operation: relaxed and energized.  In the relaxed state, the heat pump can be programmed to introduce either heated or cooled temperatures into the conditioned space, depending on the direction of the flow of refrigerant through the closed loop.

By applying a 24 volt charge of AC current (a low voltage typically used in HVAC systems), the valve becomes energized and reverses the flow, producing the opposite conditioning.  The reversing valve may be driven by the heat pump through the use of a control board or directly by a thermostat.

Will a Heat Pump Work in My Home?
