AC Guide: Why Replace Your Indoor and Outdoor AC Components at the Same Time

Monday, September 10th, 2012

Do you need to replace one of the main components of your Salt Lake City split AC system? If so, you are probably tempted to just replace whichever unit is failing in order to fix the problem quickly and cheaply. This is not always the best way to go, however. Here are six reasons why you should replace both the indoor and outdoor units at the same time.

 #1: Cost

Although replacing just the failing component – whether indoor or outdoor – will be less expensive up front, that choice often proves more costly overall. You will see just what that means in the rest of these reasons.

 #2: Advances in design

Heating and cooling technology is always advancing, so since you purchased your AC system, the products on the market have gotten quieter, more efficient and better overall. By replacing just the failing indoor component, you won’t reap all the benefits of this new technology, as the older outdoor component will still lag behind the times.

 #3: Higher efficiency

When both units are replaced at the same time, and with models that have the same technology, they work together more efficiently. That means more savings on your bills and a more comfortable home.

 #4: Matched system

Split AC systems are designed such that the indoor units are engineered to work best with a matching outdoor unit. When the system is matched, you get optimum performance and efficiency. By replacing just one component, you lose the benefits of that matching, meaning degraded efficiency and performance.

#5: Warranty considerations

A new system means new warranty coverage. Replacing both units at once means a whole new warranty that covers your whole cooling system, so you won’t have to worry about paying for any more replacements jobs for a long time.

 #6: Wear and tear

Finally, think about the wear and tear your air conditioning system has undergone since it was installed. Maybe only your outdoor unit needs to be replaced now, but since your indoor unit has tolerated the same number of hours of use, it may be on its way out sooner than later. It’s like when you buy new tires for your car– you don’t buy one or two, you buy a whole set of four so that the whole system starts fresh. That way you only do it once, and not again in six months or a year.

For all these reasons, replacing both components of a split system is often the best and least expensive route to choose when facing a replacement. For more information about replacing your Salt Lake City AC system, give Design Comfort Heating & Air Conditioning a call!

AC Tip: Energy Efficient Home Cooling

Monday, August 27th, 2012

Having an energy efficient air conditioning system in Salt Lake City place is a great way to keep cool in the summer for less. But that is far from the only thing you can do to help reduce your energy bills throughout the hottest months of the year. In fact, there are several simple steps you can take to start cutting down on your cooling costs right now and lighten the cooling load that your air conditioning system has to bear.

One of the main things to remember when you are trying to keep your house cool is that every door and window is potentially letting in warmer air from outside and letting the cooler indoor air escape. You can cut down on this considerably if you simply take the time to seal up these access points and any others you are able to find.

Putting up plastic over unused doors and windows and checking all areas of the house for drafts and adequate insulation will dramatically reduce the cost of keeping your house cool in the summer. Also, you can keep the sun from warming up your indoor air by drawing the blinds, particularly on those windows that let in the hot afternoon sun.

Putting up light colored siding and reflective roofing will also do a great deal to keep your overall cooling costs down. That is because these materials are able to direct the heat of the sun away from your house rather than letting it be absorbed so that it can heat up the inside. The vast majority of the heat that your air conditioning system has to remove from your house comes in through your roof and walls, so blocking this access point is extremely helpful in keeping your overall cooling costs down.

All of these are steps you can take to reduce the total cooling load that your air conditioning system has to deal with. But if you want your system to continue to function at peak energy efficiency, you will have to take care of it as well.

This typically means having someone come in once a year to perform a thorough inspection of your Salt Lake City air conditioning system and to clean out any debris that may have accumulated over time. Having this done will make it possible for your air conditioner to continue to function at the highest possible levels of energy efficiency for years to come.

AC Repair Question: Why is My Central Air Conditioner Making Noise?

Monday, August 13th, 2012

A good air conditioner in Salt Lake City is a life saver in the midst of a hot and sticky summer, but just because the system makes you comfortable and makes the hottest months bearable doesn’t mean you want to hear it clanging and banging all summer. If you notice excess noise coming from your air conditioner, it might be a problem that can be fixed by your technician. Here are some common causes of excess noise from an air conditioner and what you can do to fix them.

  • Blower – The blower is a motor and fan blade assembly. If the blade touches the housing or if the motor needs a tune up, it might start to make excess noise. Loose screws, foreign objects, or a need for oiling or new parts will all cause noise problems.
  • Ductwork – If the sounds you’re hearing are in the ductwork or vents, it may be due to expansion and contraction in your ventilation system. This is normal and while it may be obnoxious, it tends not to persist during the hottest months as temperature won’t fluctuate as much.
  • Bubbling Sounds – If you hear a gurgly or bubbly noise coming from your indoor unit, it may be due to a blockage in the condensate line. The easiest solution is get someone to clean the condensate line and check for any clogs or blockages in the system.
  • Clicking Sounds – If you hear a clicking sound, it is likely from the relay or contactor in the system. If this is the case, have a professional check it right away. Electrical problems are not to be taken lightly where your air conditioner is concerned.
  • Foreign Objects – Sometimes, the condenser fan will make a lot of loud noise because foreign objects get stuck in there. Sticks, leaves, toys, food from small animals – it can all get stuck in the fans and make a tremendous amount of noise. Keep the area around your condenser unit clear of debris and check it often if you hear loud noises.

Most noises from your Salt Lake City central air conditioning unit are explainable and can be fixed relatively easily. If you cannot find the source of the noise, however, and it is only getting worse, call Design Comfort Heating & Air Conditioning before the problem grows.

Important Things to Remember When Installing a Central Air Conditioner

Monday, July 16th, 2012

A good central air conditioner is a big upgrade for most Salt Lake City homeowners. If you’ve been using window units for the last few years or have an older central unit that simply doesn’t get the job done any longer, a brand new central unit will feel incredible. But, before you run out and hire someone to install your new Salt Lake City central air conditioner, there are a few things to remember.

  • Space – Make sure you have enough space for both the outdoor unit and the indoor evaporator coils.  If space is limited, there are smaller units that will use less and still provide a decent amount of cooling.
  • Supply Registers – Make sure there are enough registers in your home, in the rooms where you need the cooled air. Insufficient depositing of cooled air won’t keep you cool and will run up your energy bill.
  • Ducting – Check the duct work and make sure it can support an air conditioning system. Seal up any ducts leading into spaces you don’t want cooled like the attic or the basement.
  • Condensing Unit – Clear away a space outside where your condensing unit will be placed. It should be clear of debris and be easy to maintain throughout the year, even in the winter when snow might block it in. It should also be easy to access for installation and annual maintenance.
  • Sizing – When you call a professional, they should properly size your home and match it to a central air conditioner that fits your needs. Something too small won’t provide the level of cooling you need and something too large will cycle on and off frequently, costing you more money and putting unnecessary stress on the machine.

If you’re ready for a central air conditioner and want to start the processor, call a Salt Lake City air conditioning professional like Design Comfort Heating & Air Conditioning who can help you go through each of these issues and make sure your home is ready for the new device. Once you’ve done that, you can select a model and have it installed.

Air Conditioning Q/A: What is R410A?

Monday, July 2nd, 2012

If you’ve recently started researching a new air conditioner for your Salt Lake City home, you may have run across “R410A” – a newer form of refrigerant increasingly being used in high end air conditioning equipment. What is R410A and why is it different from the existing refrigerant most air conditioners have?

Chemical Composition

R-410A is a composite of diflouromethane and pentafluoromethane. This mixture of R-32 and R-125 creates a new compound designed to be used in commercial and residential air conditioning devices. Sometimes referred to as Puron, Genetron and EcoFluor, R-410A is a more environmentally friendly approach to cooling than the existing coolant most air conditioners use – R-22.

To date, R-22 has been the refrigerant of choice for millions of devices. However, because R-22 will no longer be permitted in new devices starting soon, R-410A is growing in popularity rapidly and will soon become the standard refrigerant option in new devices.

Environmental Impact

Despite being very similar in chemical composition to other refrigerants like Freon and R-22, R-410A does not contribute to ozone depletion, a major step forward for air conditioning. However, it has as very similar global warming impact – producing nearly 1725% more damage than carbon dioxide. One of the factors that negates this high global warming risk is the fact that R-410A is being used in a more efficient manner than past refrigerants.

Choosing R-410A

You cannot simply replace the R-22 in your cooling system with R-410A. Because it requires higher pressure, the devices that run with R-410A must be built specifically for this refrigerant. As a result, many manufacturers are starting the transition to the new refrigerant now, in anticipation of the phase out date for R-22. If you are preparing to buy a new air conditioner in Salt Lake City, keep this in mind. For more information, give Design Comfort Heating & Air Conditioning a call today!

Air Conditioning Tip: Your HVAC System’s Condensate Drain Line

Monday, June 18th, 2012

There are a lot of components involved in a properly working HVAC system. One component that many people overlook is the drain line for their Salt Lake City air conditioning system. Your air conditioning system has condenser coils that sweat the water drawn from the air in your home as it is cooled by your AC unit. These coils produce a significant volume of water, especially when it humidity is high, so a condensate drain pan is installed to capture the moisture and keep it from damaging your home.

A drain line from the drain pain out of your home is required to transfer all that extra water, but it can easily become clogged by debris in the area or simply from heavy condensation. If this happens, the drain line might need to be cleared or even replaced.

Inspecting your Condensate Drain Line

Full inspection of your drain line involves checking quite a few components, but, in short, you want to look for evidence that your condensate drain is overflowing or that the liquid in your drain pan is backing up into the air handler.

You may also notice that there is no liquid coming out of the condenser – a sign that there may be a major problem in the system that needs immediate inspection. If this happens, make sure you check for blockages and if nothing is present, call a contractor.

Cleaning Your Drain Line

Each year, it is recommended that you clean your drain line to make sure it is clear and ready for the summer’s heavy cooling and high humidity. The simplest way to do this is to disconnect the drain line and attach a hose to blow the line clear. This can get a little messy, so make sure you dress for the occasion. Another option if you have a wet/dry vac is to attach the hose to the end of the drain line and suck free any moisture still in there. Most wet/dry systems have attachments for drain line clearing or you can order one.

If your drain line is not clearing properly or you think there may be structural damage suffered during the winter, call a Salt Lake City air conditioning professional for a more thorough inspection. If you have regular maintenance done on your AC system each spring, this should be part of the process so make sure you write down any questions you have for when Design Comfort Heating & Air Conditioning visits your home.

Your HVAC System and the Gas Line

Friday, June 8th, 2012

What happens if you lose your gas line? What relationship does that simple copper pipe have to the comfort control of your home? It depends largely on the scope of your HVAC system and what time of the year you lose gas, but the answer is almost always that it will have a pretty big impact.

What Uses Gas in Your Home?

There are a number of components that use gas in your home. The first and most common is your furnace, but you will find that your water heater may also use a gas line and some packaged air conditioning systems use gas for heating components.

  • Heating – If you have a gas line, it’s very likely that your heating system uses gas as an energy source. It’s the least expensive of the three major energy sources (oil, gas and electricity) and gas furnaces and boilers are extremely efficient. In terms of how much gas you will use, one cubic foot of gas contains 1040 BTUs of heating energy per hour.So, if your furnace offers 100,000 BTUs of heating capacity, it would use 96.15 cubic feet of natural gas when running at full capacity. Keep in mind, though, that a gas furnace is rated with an AFUE rating. This is the percentage of the fuel consumed that is actually converted to heat. So, if your AFUE rating is 90%, your actual BTU production would be 90,000 for the same 96.15 cubic feet of gas. The cost of natural gas varies by location, but is generally around $1 per cubic foot.Boilers are very similar in their gas consumption rates. Boilers are rated for maximum output – so if you have a 15kW boiler – meaning it will burn the equivalent of 15 kWh of gas per hour when running at full capacity. Keep in mind that this is the maximum output. If you only have one radiator open, the actual rate may be much lower.
  • Water Heating – For a water heater, gas rates are charged by kWh, just like your boiler. The total is usually significantly less than for a boiler, but the same mechanics apply. Your water heater should have a placard or sheet that lists its maximum production per hour so you can determine how much gas it uses per hour when your hot water is in high demand.

Gas is a highly volatile substance and while there are a number of safety measures implemented in your home to protect your family, it’s important to ensure the gas lines are well maintained. Annual maintenance is a must to keep the gas working properly. If you do notice a leak or sudden loss of gas, don’t call a contractor – call the gas company immediately as it could be an emergency.

Handy Ways to Remember Your Filter Changing Schedule

Monday, April 30th, 2012

Changing the air filters in your Salt Lake City heating system and air conditioner is an essential maintenance task. The benefits of having a fresh filter for the air circulating in your home are numerous. The better air quality is good for your respiratory health, fewer allergens permeate the air, your system runs more efficiently and you save money. So why is it so difficult to remember to replace those filters? To help prevent those issues, try some of these tips to remember your replacement schedule.

Set Reminders for Later

Think of the last time you inspected and replaced your air filter. Was it more than three months ago? Replace it now. Can’t remember? Replace it anyway. Go ahead; this post will wait. Now that you’ve taken care of that, set a reminder for three months from now. Try one of these systems to remind yourself:

  • Put it into your cell phone calendar.
  • Use a calendar application that sends email alerts to remind you.
  • Circle the day on your wall or desk calendar.

Whatever method works best for you, make sure to use it and stick to it. While you are at it, set monthly reminders to inspect the filters. The EPA recommends making the switch every three months, or whenever the filter is visibly dirty.

Make a Connection

If you don’t like to have reminders, or perhaps find yourself forgetting to even set the reminders, hope is not lost. Try scheduling filter changes to coincide with something you will remember, or putting it on the same day as other routine maintenance tasks. Here are some examples:

  • Make the day of the month the same as that of your birthday or anniversary. Bonus points if your birthday is June 25, since that combines with Christmas to take care of two replacements a year. Just remember March and September and you are all set!
  • Three months is about as often as cars need oil changes, so do both on the same day. Drove 3000 miles already? Time to change the furnace filter.
  • Schedule on a holiday. In the U.S., for example, Martin Luther King Day, Easter Sunday, the Fourth of July and Columbus Day are all approximately three months from one another.

The Failsafe

If all else fails, hire a professional to inspect and change the filters for you, and rely on his appointment keeping skills to make up for any memory lapses you may have. It will cost a bit more than DIY, but at least it will get done, and the maintenance will save you on the costs of wasted energy.  To schedule these visits please call Design Comfort.

How Much Will a High Efficiency Air Conditioner Save You?

Wednesday, August 31st, 2011

When it comes to your air conditioning system in Salt Lake City, the energy efficiency rating really does matter. While you may be paying a bit more for products with higher energy efficiency ratings to begin with, you will certainly save a significant amount on your monthly cooling bills in the years to come.

Before you can evaluate your options in terms of energy efficient air conditioners, however, you will need to know how their efficiency is represented. Most air conditioners come with what is called a seasonal energy efficiency rating (SEER). A higher SEER means a more energy efficient model, and likely a higher price tag as well.

But how much more energy efficient is a SEER 10 air conditioning unit as opposed to a SEER 11? Well, the truth is that it is about 7% more efficient. However, a SEER 14 will be 23% more efficient than a SEER 10, but only 5% more efficient than a SEER 13 model.

While all of these numbers can help give you some context in which to evaluate the various air conditioners out there, they can only go so far. Turning these percentages into dollars is what you really have to do when you are trying to figure out what your monthly or yearly savings will be.

So to give you a bit of perspective, imagine that your annual cooling costs come to around $480 with your current SEER 10 air conditioning system. If you choose to upgrade to a SEER 13, you will save somewhere in the neighborhood of $110. But if you opt for the SEER 14 instead, you will gain an annual savings of closer to $140 compared to your current bill.

Of course, the SEER of a particular air conditioner is not the only thing that will cause the price of the unit to rise, nor is it the only thing that can cause your monthly cooling costs to rise. Air conditioners also need to be matched to the size of the space they will be asked to keep cool.

If the unit you have is too small to effectively cool the area in question, you are likely paying more than necessary in terms of cooling costs for less than ideal results. Similarly, if your unit is too big, you will be paying too much no matter how high a SEER rating it has. If you need help picking the unit that is right for you, contact your local professional.

Cleaning Air Conditioners

Wednesday, August 24th, 2011

One of the best things you can do to help maintain high indoor air quality in your Salt Lake City home is to clean your air conditioning system on a regular basis. While these systems make it possible to endured a long, hot summer with minimal discomfort, they can also become a breeding ground for bacteria, mold and other indoor air contaminants that can make you sick or cause other types of problems.

Improving your indoor air quality isn’t the only reason you should worry about keeping your air conditioning system clean. A properly maintained air conditioner will function more efficiently for a longer period of time.

Air Filters

Changing or cleaning out your air filters regularly is one of the easiest and most important parts of air conditioner maintenance. These air filters are your number one line of defense against all manner of indoor air pollutants, but if they become saturated, they can no longer do their job. Fortunately, changing out these filters is a quick and easy job. Just mark the date on your calendar so you don’t forget.

Ducts

Without the system of air ducts that run through your home, your air conditioner wouldn’t be able to circulate all that cool air. But they’re also a very attractive place for dust, pollen, mold and other indoor air contaminants to collect. Unfortunately, the majority of your ductwork occupies space behind walls, beneath floors and in other equally inaccessible areas of your home.

For that reason, it’s generally necessary to have a professional with specialized equipment come out and clean your ducts once a year. By keeping up with maintenance, you can be sure that your air ducts aren’t harboring dangerous contaminants that your air conditioning system can then spread throughout your home.

Cooling Coils

The cooling coil is another part of your air conditioning system that needs to be cleaned on a regular basis. If your cooling coil is dirty, it won’t actually affect your indoor air quality, but it will impede your air conditioner’s ability to function effectively. The more sediment and debris allowed to build up on your air conditioner’s cooling coil, the less efficiently it will cool the air that passes over it. And if it can’t cool the air properly, your air conditioner will have to work overtime to maintain a comfortable temperature inside your home.
