When Is It Time to Replace My Furnace?

Monday, January 27th, 2014

It can be a tricky question: “when is it time to replace my furnace?” No one wants to consider the costs involved in buying a new furnace, but sooner or later the old one is just going to become too worn to continue functioning.  So when is it time to replace your furnace? A few tips can be found below:

  • Your furnace is very old.  This might not be a deal breaker, especially if your furnace has been well maintained. But old heaters usually have a lower AFUE (Annual Fuel Utilization Efficiency) rating, which means they’re not as efficient as newer models. They might not feature the kinds of bells and whistles you’d want either. And if your heater is experiencing additional problems, its age might be the determining factor.
  • Repair bills are climbing. Most appliances need a little repair every now and again. But if it seems like the technician is living in your door step and coming in every other day to fix the furnace, then the cost of a new unit may outweigh the inconveniences and mounting bills.
  • Your monthly bills are rising for no apparent reason. Wear and tear over the years can mean that your furnace is using much more energy to do the same job, which you’ll see reflected in your monthly bills. If your costs are going up even though you’re not using the furnace any more than normal, it may be time for a new unit.

If you’re asking “when is it time to replace my furnace?” then a little professional advice can come in handy. If you need heating service in Atlanta, call Air Conditioning Experts. We can discuss your options with you and either repair your existing unit or install a new one to better suit your needs. Give us a call today to schedule an appointment. You’ll be glad you did!

Common Ductless Heating System Repairs

Thursday, January 23rd, 2014

A ductless heating system is just what it sounds like: a system that relies on separate indoor air handler units placed strategically throughout your house connected to an outdoor unit instead of a single indoor unit that sends warm air everywhere via a system of ducts. Ductless heating offers many advantages, such as the ability to tailor the temperature for different parts of the house and even turn the heat off in rooms you aren’t using. Ductless heat pumps combine heating and air conditioning functions into a single system. That works very well for heating in Atlanta, since the system is at its most effective when temperatures stay above 40 degrees or so. Unfortunately, it can run into problems just like any other heating system, and when it does, you need a qualified repair service to handle it.

Here are some common ductless heating system repairs.

  • Refrigerant leaks. Ductless  heat pumps use refrigerant to absorb heat from the outside air and transfer it into your home. When the refrigerant leaks out, your heat pump don’t be able to heat effectively, and frost can form on the coils. You can’t just scrape off the ice: the leak needs to be sealed and refrigerant levels recharged to address the issue.
  • Clogged lines. Clogged drain lines and a misaligned drain pan can both create condensate overflow in your heating unit. The overflow can end up damaging internal components if it’s not addressed.
  • Motor issues. Ductless heating systems have fans to blow warm air into your home. When the fan motor runs into trouble – either because of an electrical overload or some kind of mechanical problem – the fan won’t blow and your air won’t get heated.

For issues concerning heating in Atlanta, Air Conditioning Experts, Inc. is ready to help. We handle most problems with ductless heating systems and our trained staff of experts will perform their repairs with the utmost concern for your satisfaction and comfort.

Why Is My Furnace Not Heating?

Monday, January 20th, 2014

Georgia enjoys mild winters, but that doesn’t mean we can escape without using our heating systems over the next few months, especially during the evenings. If you lose your heat in your home, it can mean an uncomfortable stretch until repair technicians can get out to you to solve the problem.

Furnaces are common ways of home heating in Atlanta, and are usually dependable machines (provided they receive regular maintenance). However, they can still suffer malfunctions that will prevent them from providing you with the warmth you need.

We’ve put together a list of reasons that your heater might have stopped giving you warm air. Make sure you call professionals, like those at Air Conditioning Experts, Inc., the moment you have trouble with your furnace. We can deliver the heating repair in Atlanta, GA that will make your home cozy once more.

Reasons your furnace isn’t heating

Loss of fuel source: If you have an electric furnace, make sure that it is connected to a power source. If you have a natural gas furnace, there may be blockage in the gas line, or a drop in gas pressure so that the burner isn’t receiving fuel. Don’t tamper with the gas line on your own, since it is potentially hazardous. Call for professional repairs.

Thermostat malfunction: You should always check your thermostat the moment you have heating (or air conditioning) trouble; the issue may be as simple as incorrect programming. However, the thermostat itself might have malfunctioned and lost its connection to the furnace, which will prevent the furnace from turning on.

Failed pilot/electric ignition: The pilot light is responsible for lighting the gas jets in many older furnaces. If the pilot light goes out, attempt to relight it. If that won’t work, than the burner unit might be too dirty for oxygen to reach the pilot. Newer furnaces use an electric ignition to start the burners, and this may have failed. In either case, leave the repairs to professionals, since this also deals with natural gas power.

Caution: Furnace at Work! (Or Not at Work)

We do not recommend that you open the cabinet of your furnace for any reason other than a visual inspection. Attempting to repair or even make minor adjustments to a furnace—particularly a gas furnace—can be dangerous to people without experience or the proper tools. If your furnace has stopped working, you need to call licensed professionals to diagnose the problem and find a remedy.

Air Conditioning Experts, Inc. knows that if your furnace shuts down, you will want service fast—no matter the time of the day or night. That’s why we offer 24-hour emergency service. For your long-term planning, look into our Comfort Club, which offers annual maintenance to keep your furnace running.

How a Heat Pump Uses Refrigerant

Monday, January 13th, 2014

A heat pump can serve as both a heater and an air conditioner. Here in Atlanta, heat pump technology is very popular, since it works best in places with mild winters like ours. It works in a manner similar to traditional air conditioning, with a closed-loop system containing refrigerant gas. Here’s how a heat pump uses refrigerant to both warm and cool your home.

The closed-loop system contains two sets of valves and coils: one inside the house and one outside the house. In the summer time, the refrigerant is subjected to a lot of pressure by the compressor. It then moves to the outdoor condenser coils, which dissipate off the heat into the outside air and convert the gas to a liquid in the process.

The liquid then moves to the inside valve, which releases a set amount into the inside coils. There, the liquid evaporates and turns back into a gas, pulling heat from the air outside the coils in the process. A fan then blows the cool air into your home to lower the temperature.

That’s what happens in the summer, and is essentially no different than what happens in an air conditioner. With a heat pump, however, the process can basically be reversed. That means that in the winter, the indoor and outdoor coil reverse functions, with the outdoor coil absorbing heat and the indoor coil releasing the heat into your home.

If you know how a heat pump uses refrigerant, you can begin to understand what happens when your heat pump needs repairs. Here in Atlanta, heat pump issues can be addressed by Air Conditioning Experts. We pride ourselves on doing the job right the first time, every time, so give us a call today!

Heating System Sizing Guide

Monday, January 6th, 2014

Although we have short winter seasons in Atlanta, they still can present us with some tough, chilly days and even icier nights. Having a heating system that’s the right size to keep your home warm until the spring is a necessity. But heater size is a tougher thing to determine than you might at first think. Many homeowners often imagine that going for the largest heater available with their budget is the best path, while other think that maybe going a bit smaller and saving money will be sufficient.

First of all, there is no single answer to the question, “How large a heater should I have installed?” Every home has different needs based on its size, insulation, location, number of residents, amount of heat-radiating appliances, windows and the direction they face, and numerous other factors that homeowners rarely consider. This is why it’s vital to consult with HVAC professionals when it’s time for a new heating installation in Atlanta, GA. Let Air Conditioning Experts serve as your guide for installation: we’ve helped people in Atlanta get quality heating since 1995.

Sizing a heater

The process of finding out what size of heating system to install in a home is called “sizing.” The key step in sizing a heater is the heat load calculation. A “heat load” is the amount of heat a home requires to maintain a desired temperature, and the calculation includes the many factors that contribute both to heat gain (light from east or west facing windows, energy from appliances or lights) and heat loss (insulation, the space needed to heat, home layout). The net result of the calculation is how many BTUs (British Thermal Units) are required per hour to maintain the desired comfort level.

Using the results of the heat load calculation, the HVAC installers can determine the size of heater that will provide you with the amount of heat you need for the comfort of you and your family.

Problems of an incorrectly sized heater

It’s important that your heater be neither to large or too small. A small heater will inefficiently heat the house and need to run so often it will cost much more to operate than any “savings” you may get from its initial installation. A heater that’s too large will continually turn on and off as it reaches the target temperature too early (“short cycling”), which will also drain power and lead to repair needs and an early replacement.

So when you need new heating installation in Atlanta, GA, contact professionals to help from the beginning. Air Conditioning Experts will make sure you receive the properly sized heater for your home, and we’ll install it quickly and get the job done right the first time.
