Marietta Heating Question: Do I Need to Schedule Professional Heating Repair?

Monday, November 26th, 2012

With all the busy things that start happening in Marietta over the holiday season, your heating system can take a back seat. But even through all the hustle and bustle, it’s important to keep an eye on your heating system to make sure that you don’t need repairs. Sometimes it can be difficult to know when you need to call for heating service. We thought out customers in the Marietta area would benefit from a short list of some of the most common heating repairs that we service.

Furnace Noises

Your furnace can make all kinds of noises throughout its use. However, there are a few that you should keep an eye out for because they can indicate a dangerous problem with your furnace.

  • Rattling – If you notice that your furnace is making a rattling noise it could mean that your heat exchanger is cracked. This might mean that your furnace is leaking carbon monoxide into your home. The heat exchanger is supposed to do two things: first, heat the air going into your home and second, safely exhaust dangerous combustion fumes. When it cracks, those fumes can enter your home’s air supply.
  • Rumbling – If you have an oil burning furnace and you hear a rumbling when you turn off the furnace, this could also be a dangerous problem. It likely means that there is uncombusted fuel in the chamber.
  • Squealing – If your furnace is making a squealing sound while its running you should call a heating contractor. While this isn’t a life threatening issue, it probably means that the fan belt is worn out and rubbing against something.

Yellow Flames

If you have a gas fired boiler or furnace another serious issue has to do with the flames on the burner. The flames are supposed to burn still and have a blue color. If you notice that the flames are dancing or if they’re yellow, this can also mean that the heat exchanger is cracked.

Low Heat, No Heat or Low Air Flow

These three heating problems are also very common in Marietta. There are many different causes for these problems. It could be your thermostat, but it could also have to do with your ductwork having unnecessary bends or being pinched. Most often, though, these issues arise from a clogged air filter.

If you’re having any of these problems it’s probably best to call a licensed Marietta heating contractor.

Atlanta Heating FAQ: How Do Heat Pumps Compare to Furnaces?

Monday, November 19th, 2012

Are you thinking about buying a new heating system but not sure what kind to get? Whether you have a new home or old one, comparing heat pumps and furnaces is a good place to start when you are thinking about a new heater for your Atlanta area home. Call Cool Air Mechanical if you have any questions about the heat pump and furnace models we sell and install.

Here are few notes for comparison to get you started.

Don’t I need a backup furnace for my heat pump anyway?

Not necessarily. Using a backup heating source all depends on where you live and the layout of your home. If you have a large home in a cold climate, then yes, you may need a backup furnace to heat your home when temperatures drop below freezing. An air source heat pump will heat a home more efficiently in milder climates. You can also think about a dual fuel system that automatically switches from the electric heat pump to a gas furnace during colder weather. The gas furnace will cost less to run since gas tends to be more efficient than electricity.

Which type of heater needs more maintenance?

Any type of heating system will need routine maintenance. Annual tune-ups contribute to the efficiency and safe operation of your heating system. Maintenance also helps extend the life of the system since it helps keep repair needs down. The only difference is that your heat pump may need two tune-ups per year—one before the heating season and another before the cooling season.

Which one is more efficient: Heat pump or furnace?

Again, this all depends on several factors. You’ll need to answer some questions first. How big is your home? What are your heating needs? How cold is the climate? Where is your home located? How many rooms do you have? How many doors and windows are there in your home? How much sunlight does your home get in the winter? Is your home properly insulated and sealed? Once you’ve answered these, speak with a professional heating contractor about your options.

At Cool Air Mechanical, we’d be glad to go over all the different factors to help you make an informed decision. Call us if you are interested in a new heat pump or furnace for your Atlanta area home.

Decatur Water Heater Guide: Why Replace Your Water Heater?

Monday, November 12th, 2012

Can you name a component in your home in Decatur that you use every day? Your water heater is probably one of those appliances. You use it to shower, shave, laundry, wash dishes and more. With so many important jobs, replacing your water heater is a huge decision. But how do you know it’s time to replace your water heater. We’ve assembled a small collection of reasons why you might need to replace your water heater.

Rust Colored Water

Rust colored hot water is normally a very bad sign for your water heater. It typically means that the inside of your water heater has started to rust. This problem cannot be repaired and you will most likely need to replace the whole water heater. While rust in your water could be caused by corrosion in your pipes, if you notice rust-colored hot water only there’s a good chance it’s from your water heater.

Leaking Water

If you start to notice water collecting underneath your water heater, you may want to start considering replacing your water heater. This can sometimes mean that the inside of your water heater has rusted through and is now starting to leak. Make sure you call a professional to inspect your water heater. This could also be from a small hole in a pipe near your water.

Improved Efficiency

If you have an older water heater, there’s a good chance that it’s using a lot of energy to heat your water. Newer water heaters typically have a greater efficiency rating than older models. Water heaters are given an efficiency rating called an annual fuel utilization efficiency rating. This rating indicates how much of the fuel consumed is actually converted into heat. Most older water heaters have an AFUE of around 60% which means that they waste 40% of the fuel they use. Many newer models have an AFUE rating of 92% and above.

If you have any questions about the water heater in your Decatur home, call the experts at Cool Air Mechanical. We have years of experience working with all types and brands of water heaters. We can help you pick out a new water heater that fits your needs and install it for you. Call us today!

When Should I Turn On The Backup Heat For My Dual Fuel Heating System in Atlanta?

Monday, November 5th, 2012

This is a common question that we get from some of our customers in the Atlanta area. Dual fuel systems can be more complicated than a single fuel system because the secondary heating system is dependent upon several factors in order to work properly. In this blog post, we’ll explore what a dual fuel system is, why it’s necessary and when you should turn it on.

Why Do You Need Dual Fuel Systems?

While heat pumps are a terrific way to increase the efficiency of your home, they do come with draw backs. One of those draw backs is that when the temperature outside becomes too cold, the heat pump will actually become less efficient. A great way to solve this problem is with a dual fuel system. In Atlanta, it can get cold which is why many of our customers who use heat pumps often have a backup system that will provide supplemental heat when the temperature drops too low.

When To Turn On Your Dual Fuel Heating System

In many cases, the actual turning on of your secondary system is done automatically by an outside sensor. The exact temperature at which it happens is normally set by your heating installation contractor. Traditionally, the temperature is between 30° F and 40° F. This temperature is highly subjective and should be adjusted to your liking. However, you should absolutely consult with your local Atlanta heating company to figure out what the best temperature is for your home.

The Price of Fuel

As we mentioned above, the main reason for a dual fuel heating system is efficiency. Your dual fuel system can also be adjusted depending on what happens with fuel prices. For example, if your secondary system is a gas-fired furnace, you can have the furnace turn on sooner if gas becomes cheaper than electricity.

If you have any questions about your dual fuel system in your home in Atlanta, give Cool Air Mechanical a call today. We’ll be happy to talk with you about what temperature it should be set at and how to make your system run more efficiently.
