Water Heater Repair FAQ: Should I Flush My Tank?

Wednesday, March 4th, 2015

You may have heard before that you’re supposed to flush your water heater tank every year or so. This is partially true. Your water heater does need regular flushing, although how often the tank is drained depends on a couple of factors. However, this is not a job for average homeowners to take on by themselves. Flushing a tank is a job for professionals only if you want to make sure that everything goes as smoothly as possible.

Talk to the people at Cool Air Mechanical for information about water heaters in Marietta. We can recommend professional services for prevention or to resolve any potential issues.

Many technicians advise that you service your water heater every year. This includes draining the tank to eliminate any sediment buildup. Sediment builds up in the tank as a result of minerals commonly found in the water supply. Over time, these minerals can increase the pressure in the tank to dangerous levels or they may block the pipes. Flushing the tank from time to time gets rid of these minerals and helps keep your tank in good working condition.

However, if you attempt to handle this service on your own, there are a couple of ways it can go wrong. Electrical trouble is perhaps the most jarring of possibilities. You’ll need to make sure that the power is off to the water heater unit before servicing it and that the water is shut off while draining the tank.

There are a few other things that may go wrong with a D-I-Y tank flushing. Flooding is always a possibility. And if you don’t open and shut all of the right valves, you may create a vacuum in the pipes that leads to noisy operation the next time you turn on the hot water. Besides, when you call professionals for the job, you’ll get comprehensive maintenance service for many of the different parts of your unit as well.

Call Cool Air Mechanical today to ask a professional to flush your water heater tank in Marietta. Our technicians will also go over all of the most important components of your system to keep everything running in top shape and can recommend services to improve the quality of your water heater.

How Long Can I Delay Heating Repair?

Wednesday, February 4th, 2015

To be honest, if you think that your heating system needs repair, you shouldn’t delay it at all. The longer you delay heating repair for a malfunctioning system, the more damage you’re likely to cause. In some cases, waiting to address a heating system’s problem can lead to a complete breakdown. Instead of delaying heating repair because you don’t want to deal with it, you should adopt practices that lessen the frequency of heating issues. Let’s take a look at some of the things you can do to keep your system healthy, and reduce the frequency of heating repairs.

Schedule Annual Maintenance

The most important thing you can do to preserve the health of your heating system is to schedule annual preventive maintenance. Having your heating system checked out at least once a year, regardless of whether or not it is having issues, will help ensure that your system is in top physical condition. Any parts that are starting to malfunction can be identified and replaced before they start causing major issues. This kind of maintenance is so helpful, in fact, that many warranties on heating systems require it in order to stay valid. So, if you really want to keep your heating system healthy, don’t wait for it to start showing signs of distress. Schedule preventive maintenance at least once a year.

Don’t Ignore Problems

Not all issues with heating systems will provide any sort of warning sign, but many of them do. If you have reason to believe that your heating system isn’t working properly, schedule a maintenance call immediately. Strange noises coming from the heating system are very common indicators of a problem, as well as uneven heating across the house and higher heating bills. Though having to deal with a maintenance call may be annoying, ignoring the problem for any length of time only increases the likelihood of the problem developing into something much more damaging and expensive. Don’t delay, call a professional as soon as you notice unusual behavior from your system.

If you need heating repair, schedule an appointment with Cool Air Mechanical today. We provide professional heating repair services in the Marietta area.

When Is an Electric Water Heater a Good Option for My Home?

Wednesday, September 24th, 2014

When you need a new water heater in Marietta, it may be difficult to decide on your own which type of unit is right for your home. Today, there are many new types of units available on the market. Storage tank water heaters remain the most popular type due to the lower cost, but tankless water heaters are rising in popularity. In general, however, if you’ve never run into problems with your traditional storage tank water heater, you may decide to replace it with a similar system. But when you need a storage tank water heater for a new home, or if you’re looking at different options, there are two general types of unit, electric and gas-powered, which may lead you to wonder which type is right for you.

Electric water heaters work using the same heat rising principle as gas-powered heaters. A pipe that leads to the bottom of the tank lets cold water in. Here, a burner heats the water from underneath the unit in a gas-powered water heater. With an electric unit, a heating element inside the tank heats the water instead. Hot water naturally rises above the denser cold water and flows into your home through a pipe positioned at the top of the tank.

Both types of units are about equally effective at providing hot water. But for the most part, people choose electric water heaters when they don’t have access to natural gas service. While gas heaters may be more costly than electric, the cost of operation tends to be much higher with electric water heater units because the cost of electricity is higher than the cost of gas in most areas. However, an electric water heater may best for those who need a smaller unit to heat water for a smaller apartment. In fact, you can even upgrade your system with an insulated water heater blanket to prevent heat loss and lower your bills.

The decision ultimately has to do with the size of your home and your family, your energy concerns, particular needs for installation and monthly cost, and what type of system you are replacing. A professional technician will discuss the cost of installation as well as which types of units may be most efficient in your home. Cost will vary depending on what size tank you need and any upgrades you choose, so you should always check with your technician first. For professional water heater installation in Marietta, call the experts today at Cool Air Mechanical.

3 Common Signs That You Need Commercial HVAC Repair

Thursday, August 28th, 2014

Problems with your commercial HVAC system can have a direct impact on your business; this is why it’s so important to attend to repairs right away. You don’t have to be an HVAC expert to spot the signs of developing problems, but it does help to know what to look for. Our Cool Air Mechanical technicians have put together a short list of common signs that can indicate the need for repair to your commercial HVAC system in Marietta.

3 Signs of Possible Problems

Following are 3 signs your commercial AC may be experiencing problems:

  • AC is blowing warm air – there are several problems that can cause your air conditioner to blow warm air, but the bottom line is that no matter what the reason, it needs to be fixed quickly. This is why it’s important to hire a technician who has experience with commercial HVAC systems.
  • Decrease in airflow – it won’t matter how cool your air is if you aren’t getting enough of it. A decrease in airflow can be the result of blockages, faulty ductwork or fan problems. Problems with airflow can put stress on your AC system, so the sooner it can be repaired, the better for you and your AC.
  • Excessive humidity – are you feeling extra moisture in your business space? Excess humidity can cause problems beyond discomfort, including damage from moisture and mold and mildew growth. No business owner wants to see products or merchandise ruined by excess humidity, so it’s best to call a professional as soon as possible.

Why It’s Important to Hire a Commercial Specialist

Commercial HVAC systems are large and complicated, especially when compared to residential systems. This is why it’s important to hire professionals with commercial HVAC repair experience.

Are you seeing the signs of possible problems with your commercial HVAC system? Cool Air Mechanical brings over four decades of commercial HVAC repair experience to Marietta business owners with every job. If you are seeing the signs of possible problems, call us today and schedule an appointment.

How Your Ducts Become Dirty

Thursday, June 12th, 2014

How clean are the ducts in your home? If you haven’t scheduled regular professional cleaning for them in two years or more, you might be in for an unpleasant surprise if you reach down inside one of the vents with a handheld mirror to get a view of the interior. No matter how clean a home you try to keep, your ducts will get dirty over time to the point that the dust, dirt, and other debris inside can have a negative impact on your indoor air quality and lower the performance of your heater and air conditioner, even leading to damaging them.

We’ll explain how your ducts get this way to help you understand why regular, professional duct cleaning in Marietta, GA is essential for maintaining clean air and a working HVAC system. To schedule quality ductwork cleaning, contact our air quality specialists at Cool Air Mechanical today.

How a Home’s Ductwork Becomes Dirty

Although a cleaner house will slow down how fast dust and dirt gather inside a ventilation system, no amount of cleanliness can stop the eventual build-up. The reason for this is that the ventilation system is constantly circulating the air inside your home, and any dirt and dust inside the rooms will eventually find their way into the ductwork. Since the ducts are sealed along their length to prevent the loss of air pressure, they are basically dust traps: as dirt and other particles enter the ducts, they become trapped inside with no way to escape (except to get blown back out into your air or dragged into the AC). Dust that you sweep up will fly into the air and into the return vents, joining the rest of the dust. Homes have such effective air sealing on them today to make them more energy efficient that there are few places to which the dust inside your house can escape.

You can ventilate your home with open doors and windows, but this 1) will not reach into and clean out the ducts, and 2) may bring in more foreign particles which will then become trapped in the house and circulated through the ventilation with the rest of the dust.

There is another potential threat to the interior of your ducts: mold. Mold spores can enter the ventilation system and take hold and start to grow in humid weather. If your home suffers from unusually high humidity, this can become a serious issue.

However, you have help available for all these problems: the indoor air quality experts at Cool Air Mechanical. We offer professional duct cleaning and other indoor air quality service in Marietta, GA that will remove this reservoir of dust and dirt from your home. We also remediate mold with UV germicidal lights, and offer dehumidifiers to help reduce the risk of mold growth (and increase your summer comfort). Give us a call today for cleaner ducts.

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!

Heat Pump Installation Question: Will a Heat Pump Work with My Air Ducts?

Friday, November 15th, 2013

If you’ve done research into heat pumps in your quest to get the best comfort for your home, you already know the huge advantages they offer: a heater and air conditioner combined, high energy-efficient performance, lowered indoor humidity. Heat pumps don’t work in every part of the country since their heating function can encounter difficulty with winter temperatures below freezing, but for Georgia’s weather they are ideal.

However, if you’re replacing a central air conditioner that uses ducts, or a forced-air heater like a furnace, you might have some concerns about whether a heat pump will work with this existing ductwork. We’ll address this in this post. For professional advice and expert heat pump installation in Marietta, GA, schedule an appointment with the technicians at Cool Air Mechanical.

Heat pumps and your ducts

Heat pumps operate similarly to air conditioners, so they must use forced air to move around heated and cooled air to your house. If you already have ducts from an air conditioner, then your new heat pump will hook right up to them when it replaces your AC.

However, while you won’t encounter much difference with cooling your home with that same set of ducts, you may have issues with heating, especially if you didn’t use the ducts for heating because you had a system like a boiler that didn’t use forced air. Your ducts might not be optimized to handle the heat from an air pump.

This is why you need to contact professionals when you want to have a heat pump installed—even before you choose a system. Technicians can inspect your home’s current ductwork to see if it will work with the new demands a heat pump will put on it. If there are any repairs required before the installation starts, these technicians will take care of it. You will probably experience few difficulties in your ducts when you make the switch to a heat pump.

However, if a heat pump won’t work with your existing ducts for some reason, you don’t have to worry about abandoning the heat pump as an option entirely. Heat pumps come in ductless models that used mounted air handlers in different rooms of your home to provide heating and cooling. Ask professionals about the feasibility of going with a ductless system.

Call in the experts

Getting any home comfort system installed requires a great deal of work with attention to detail applied at each stage of the process. You need highly trained HVAC specialists to take care of this. If you contact Cool Air Mechanical when you think heat pump installation in Marietta, GA is the best choice, you’ll find out if the new system will work with your ducts. When it comes time to do the installation, Cool Air Mechanical will make sure your new system hooks up seamlessly with your old ductwork so you’ll get years of quality comfort from your heat pump.

In cases like these, you need to call on an Atlanta, GA furnace repair specialist like Cool Air Mechanical, who can inspect, clean, mend and replace damaged parts.

Another indication that your furnace may be in need of repair is if you notice that it is no longer heating as well as it once did, or that it heats your home unevenly.

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. Cool Air Mechanical has years of experience offering high quality and reliable heating services throughout the Marietta area. We would love to talk with you about how we can help keep your family safe and comfortable this winter.

Atlanta Mold Removal Question: How Will I Know If I Need Mold Testing Services

Monday, October 29th, 2012

In large quantities, mold can negatively impact air quality in your home. But how can you tell if you have a mold problem? We’ve put together a short list of common signs that mold could be growing in your home in Atlanta. If you suspect that you have a mold problem, you should call a qualified mold removal specialist immediately.

Visually See Mold

Mold growth is pretty common your bathroom. You normally will see black or gray spots of mold growing on shower curtains, shower doors or around your sink. But in your basement, cellar or attic, mold might be more difficult to spot.

Strange Odor

Mold has a very distinct smell. If you notice a persistent, “earthy” smell in certain rooms and areas of your house there’s a good chance that it’s mold. If you notice that whenever you turn on your heater or your air conditioning that there’s a musty smell, there might be mold in your ducts. The only way to be sure is to have a professional mold detection company come out and go through your house.


Mold reproduces by releases spores into the air. The spores float around in the air until they land on a surface. Once there, they can start to reproduce and releases even more spores. When you inhale spores there can be a number of physical responses. Common symptoms include headache, sneezing, irritated eyes, runny nose and irritation of mucous membranes including your throat, nasal cavities and lungs.

Recent Water Damage

There one thing that mold absolutely has to have in order to grow: moisture. Without moisture, mold can’t exist. If you recently had a flood or a pipe break, there could be moisture still present in your floor or walls that is allowing mold to grow. Mold doesn’t always appear after water damage, but it is something to be aware of. One common culprit for this is your air conditioning unit condensation lines. These lines drain water away from your AC system. If they get clogged the unit will leak water which can allow for mold growth.

If you suspect that you may have mold in your home in Atlanta, you should call Cool Air Mechanical immediately. Mold is not something to be taken lightly. It needs to be removed by a professional and treated as soon as possible.
