How Duct Leaks Can Lead to Heating Repair

Monday, January 5th, 2015

The ducts in your home essentially have two very important jobs: transporting the air from inside of your house to the heating and air conditioning unit and bringing the newly conditioned or heated air into your home. So a well-designed duct system is vital to the operation of any forced-air heating system such as a furnace or heat pump.

A good installer will design the ducts in such a way that it will be difficult for them to develop leaks and cracks, yet a majority of homes in the U.S. still have a problem with leaky ducts.

Ductwork Holes

Many homes have at least a small hole somewhere in the ductwork, but this may seem like no big deal to some. However, when your heating system generates warm air and some of that leaks into an unconditioned attic or crawlspace, it can mean a lot of trouble for your heating system. It may surprise you to learn that duct leaks can cause components of a furnace or heat pump to break down, leading to the need for heating repair.

Duct Leaks

Duct leaks can be difficult for the average homeowner to detect. A leak is often located well in the duct system, away from your sight, but your heating system still suffers. As heat escapes through small leaks and cracks, the air that finally arrives at the vents is slightly cooler, and there’s less of it. This means it will take your home a long time to finally reach the proper temperature, which means your unit will have to run for a lot longer. This can cost you more in utilities, and overwork the parts of your system.

Suddenly, the components of your heater have to work overtime to raise the temperature as needed. The fan motors may begin to fail, the heat pump compressor may begin to stutter, or the controls of a furnace may give out. So how can you avoid this possibility?

Goettl Good Guys Air Conditioning offers blower door testing and duct inspection to help determine whether there are leaks that require immediate repair. For duct sealing, home efficiency testing, or heating repair in Tempe, AZ, call our skilled team today.

Scheduling an Air Conditioning Tune Up Can Lower Your Bills

Monday, September 15th, 2014

The best way to keep your AC in top shape is scheduling an air conditioning tune up. Maintenance is an important part of owning an air conditioning system, but if your unit appears to be working just fine, this vital step may fall by the wayside. During a maintenance visit, a technician cleans and inspects your system, and makes adjustments to some components. This is important because there may be hidden problems that need repair. However, did you know that an air conditioning tune up can actually lower your monthly bills? Let’s look at a few specific steps of an air conditioning tune up that may actually save you money.

  • Cleaning the Coils: The indoor evaporator coil absorbs heat from your home, while the outdoor condenser coil helps it to dissipate. If either of these coils are too dirty, the heat exchange process slows down, which means decreased efficiency.
  • Checking Electrical Connections: Electrical problems are one of the main reasons people call for repairs, but they may be caught ahead of time with maintenance. A technician will test the electrical connections and ensure the correct voltage, keeping contactors from wearing down and consuming energy.
  • Oil the Motors: The fans in your AC are run by motors, and if one of these needs lubrication, it may not be effective. A slow indoor fan will take longer to distribute air throughout the home, which means you’ll spend more running your AC for longer periods of time.
  • Test for Refrigerant Leaks: Your system needs a certain amount of refrigerant to run efficiently. Low levels means it will take longer to cool your home, reducing efficiency, and it may also cause problems for the compressor.
  • Check the Thermostat: If you set your thermostat one or two degrees lower every day, you’ll notice the difference in your bills. So a thermostat that is inaccurate may cost you more every month, and could lead to compressor damage if faulty wiring causes to your unit to hard start.

Scheduling a thorough air conditioning tune up in Tempe with the folks at Goettl Good Guys Air Conditioning can save you a lot of money when done regularly. Give us a call today!

What Are Dual Fuel Systems and How Do They Work?

Friday, May 30th, 2014

Heat pumps are one of the best systems available for home comfort on the market today. These systems can either heat or cool a home, and instead of burning fuel to do their job—like furnaces and boilers—they work through the system of heat exchange that moves heat from one place to another using only a modest amount of electricity. Heat pumps are fantastic ways to have year-round comfort in Arizona.

There is one disadvantage that heat pumps have, however, but through the use of a dual fuel system, they can overcome this. We’ll look into dual fuel AC systems in Tempe, AZ and what they can do for you. For a consultation to see if a heat pump is ideal for your home, either on its own or as a dual fuel system, call Goettl Good Guys Air Conditioning. We have many years of experience finding ways to cool and heat the Valley of the Sun.

How dual fuel hybrid systems maintain heat pump efficiency

Here is the main drawback of heat pumps: at extreme low temperatures, they will have trouble with maintaining their heating efficiency. Because a heat pump must remove heat from outside and bring it inside when in heating mode, the lower the outdoor temperature, the less heat is available for it to use. In most cool temperatures, this is not a problem—but when the thermometer drops below the economic balance point (which varies based on humidity), the heat pump will begin to experience troubles.

A dual fuel hybrid system combats this with a smaller backup heater that uses a different fuel source. Most backup heaters are natural gas furnaces, although propane furnaces are also common for homes that lack access to a natural gas pipeline. When the temperature reaches the economic balance point and the heat pump starts to lose efficiency, the backup heater automatically switches on and compensates for the loss of heat. As soon as the temperature rises back above the economic balance point, the backup heater shuts off.

Since heat pumps are known for their energy saving abilities in heating mode, a dual fuel system is an effective way to bump up a heat pump’s performance while only making a small extra sacrifice in costs. The backup system will only need to run occasionally, so it’s a less expensive option than having a full furnace or boiler rather than a heat pump.

Your home may not have the need for a hybrid system to assist the heat pump; to find out, call on the experts at Goettl Good Guys Air Conditioning.

We have many years of experience installing all kinds of heat pumps and dual fuel AC systems in Tempe, AZ, so you can trust that we will find the right solution for your home and family.

Problems with Your Heater in the Summer

Tuesday, April 15th, 2014

A summer in Tempe will tax air conditioners to their limits, and keeping an AC working is a homeowner priority. So if you don’t think much about your home’s heater during the next couple of months, that’s perfectly understandable. However, that doesn’t mean it’s a good idea. The summer offers an ideal time to tackle problems you may have encountered with your heater earlier in the year. And, if you’re like many homeowners and use a combination of a furnace and an air conditioner, problems with your ductwork can end up causing damage to your heater during those months when it isn’t in use.

Call Goettl Good Guys Air Conditioning any time this summer for heating repair in Tempe, AZ. Don’t put off heater problems until the cold weather sets in; call us when the problems are easier to fix and it won’t bother you to have the heat shut off for a stretch.

If more than a year has gone past since your heater received an inspection and tune-up, then call Goettl Good Guys Air Conditioning to sign up for our maintenance plan.

What might be wrong with my heater in summer?

Let’s phrase that a bit differently: “What might be wrong with your heater right before summer?” When the winter heating season came to a close, your home’s heating system may have started to run into operating problems causing spikes in your bills and uneven comfort throughout your home. If you shut down the system for the season with such problems unrepaired, you’re risking bigger troubles later in the year, probably during a time when you can’t afford to go without your heater. As summer heat arrives, have a technician take a look at the strange behavior from your heater. Warning signs include: grinding, booming, and clicking sounds—any strange sounds, actually—from the cabinet; odd smells from the vents; fluctuations in heating levels; the system “hard starting”; low airflow; and abrupt rises in energy bills. Do not allow such omens of malfunctions to go without repairs this summer.

Ductwork issues that affect your central air conditioner will also affect your forced-air heater (i.e. a furnace) since they use the same ventilation system. Breaks in ducts need sealing as soon as possible, because they will not only damage your AC’s cooling ability, they could lead to damage to your heater.

The air filter for your AC is also your furnace’s filter, and if you don’t change it regularly during summer you could end up causing damage to your heating system along with the AC. Please change the filter once a month this summer, for your heating system’s sake as well as your AC’s.

Even if you don’t think your home’s heater has summer repair needs, make sure that it’s up to date on its maintenance through our regular maintenance program.  You can reach us 24/7 for heating repair in Tempe, AZ.

Why Heat Pumps Work so Well in Tempe

Wednesday, February 5th, 2014

Heat pumps serve as both heaters and air conditioners combined into a single unit, and can appear either as centralized systems or broken into individual units are part of a ductless mini-split system. They make a popular alternative to more traditional forms of heating such as forced-air furnaces, and because of the way they function, heat pumps in Tempe just make a whole lot of sense. The reasons why have to do with our particular climate, as well as a few related factors. Here’s why heat pumps work so well in Tempe.

The principle behind heat pumps is the same as the principle behind air conditioning. Refrigerant gas moves through a closed loop system that first reduces it to a liquid state (which bleeds heat into the nearby air), then returns it to a gaseous state (which pulls heat from the surrounding air). Regular air conditioners simply vent the hot air and make use of the cold air, but heat pumps allow you to make use of both. It’s an efficient system because it doesn’t actually need to create any heat or coldness itself. It merely facilitates a heat exchange from the shifting states of the refrigerant. That means it uses much less energy than traditional forms of heating, which saves you a great deal of money on monthly costs.

There’s just one catch. When temperatures drop below 40 degrees Fahrenheit, heat pumps lose a lot of their efficiency. Back East, that usually means combining heat pumps with a smaller furnace to create a hybrid heating system. Luckily, Arizona residents only rarely experience temperatures that low, which means that stand-alone heat pumps remain efficient and cost effective throughout the year.

In the end, that’s really the name of the game: providing adequate heat and comfort levels at the lowest possible cost. Our desert heat keeps winters very mild (and summers scorching), which is why heat pumps work so well in Tempe. Goettl Good Guys Air Conditioning can install and repair heat pumps and provide other heating services in Tempe with your complete satisfaction in mind at all times.

Why Do Heat Pumps Use Refrigerant?

Saturday, January 18th, 2014

A heat pump is an alternative to more traditional forms of heating and air conditioning, combining both functions into a single unit. When it comes to using heat pumps in Tempe, AZ, many residents are quite familiar, since they work extremely well in a desert environment like ours. Refrigerant gas is the key to a heat pump’s functioning, cycling it through a system of valves and coils to alternately warm and cool the air. Why do heat pumps use refrigerant? Because it’s a very efficient way to deliver the conditioned air you need without using a lot of energy.

Refrigerant serves as a sort of transfer for different temperatures, adding heat to the surrounding air or pulling it from the surrounding air as it transitions from a liquid to a gas and back again. At the start of the cycle, it enters a compressor valve, which subjects it to a lot of heat and pressure, then into a compressor coil, which bleeds the heat into the air and returns it to a liquid state. Later on in the cycle, it enters an evaporator coil, which pulls heat form the surrounding air as it moves from a liquid to a gaseous state. (In heat pumps, that process can shift from indoor to outdoor coils and back, allowing you to heat your home with the warm air in the winter, and cool it with the cold air in the summer.)

None of that involves actually creating any heat of coldness. This differs markedly from gas-powered furnaces, which require fuel to burn, and from electric furnace, which use electric coils to create the heat directly. Heat pumps don’t need to create any energy to manufacture heat. The refrigerant does he job for them. All they need to do is circulate the refrigerant through the system, a process that takes much less energy than other types of heating.

What Causes My Air Conditioning System to Rattle?

Friday, October 18th, 2013

One of the pleasant side effects of home air conditioning is the soothing white noise they produce, which can effectively block distracting outdoor sounds. When your AC begins to make odd noises, it not only breaks up that barrier of white noise, it might also be a signal that the AC system needs attention.

Of the different strange sounds an AC can make, rattling is one of the most common. We have often made service calls to attend to rattling air conditioning in Tempe, AZ, so we can explain some of the reasons it can occur. If you start hearing your AC rattle, contact Goettl Good Guys Air Conditioning, and we’ll get right out to you to discover what the trouble is and fix it before it grows into bigger trouble.

Loose panels: This is the simplest explanation for a rattling sound. Sometimes the panels on the cabinets housing the condenser or the evaporator will become dislodged because of screws that have worked loose or weren’t screwed back tight enough after the panel was opened. Before considering other issues, make sure the panels are secure.

Debris: Your air conditioner’s cabinets should be as free as possible from outside contamination. But if the air filter becomes clogged, or the outdoor unit doesn’t have a clear area around it, then dirt, gravel, leaves, sticks, and other small items can enter the cabinet and start getting knocked around. This requires immediate attention: not only will such debris damage the AC’s components, but you have to find out how the debris got inside so you can prevent it from happening again.

Misaligned fan: One of the AC’s fans may be striking its casing, either because of damage (from the debris mentioned above) or poor installation. This will become progressively worse until the fan no longer works, so have it fixed as soon as you can.

Broken motors: The motors that run the fans and the condenser in an air conditioner contain the most moving parts of any component in the system. If the motors suffer damage or start to wear down, their internal parts can become dislodged and start to rattle around. This is another problem that debris infiltration can create.

Although a rattling air conditioner may need only a simple fix, it could also indicate the start of an issue that will only grow worse and trigger a domino effect of other repair needs. Since many of these problems come from debris, make sure you regularly change the air filter to keep the interior of the AC clean. But when that rattling noise starts, be prepared to call for professional help—you want the problem solved when it’s still small.
