5 Energy Saving Tips for Winter – Lowering Your Heating Costs

During wintertime, most homeowners experience a significant increase in energy consumption along with a higher energy bill. Even in Dallas, Fortunately, there are simple steps you can take to lower your home heating costs dramatically during winter.

1. Adjust Your Thermostat – During winter, a comfortable level to set a household thermostat is at approximately 68 degrees. At this level, your HVAC system goes through fewer cycles and uses less total energy. For times when your family is away from home for long periods, consider turning the thermostat down an additional 5 degrees to lower your energy bill even more. For even more long-term energy savings, invest in a programmable thermostat that automatically adjusts temperature settings while your family is sleeping or outside of the home.

2. Insulate Properly – Insulation is important for high HVAC efficiency levels, however the benefits of taking the time to properly insulate your home skyrocket during wintertime. By insulating areas in your home such as the interior and exterior walls and ceilings, you can dramatically reduce the level of heat loss that naturally occurs, which in turn lowers your overall energy costs.

3. Weatherize Your Home – Weatherizing, which protects your home from elements such as sun, wind and rain, has a secondary benefit in reducing overall energy usage while simultaneously increasing HVAC efficiency. The process involves going through the building and sealing off any openings where there is unwanted ventilation. This includes sealing openings in doors, windows, ceilings and walls no matter how miniscule they may seem. Properly weatherizing the average home has the potential to reduce energy costs by to up 10 percent.

4. Service Your HVAC System – It is important to head into winter weather with a heating and cooling system that is working at its highest efficiency level, and is free from any faults that can lead to problems later on. Have your system serviced by professional technicians, like those at Lex Air Conditioning. They will change filters and thoroughly clean air ducts to ensure that your entire HVAC system is functioning properly. This results in lower energy costs and greater household comfort.

5. Use An Energy Star HVAC System – One of the most effective ways of controlling your winter energy consumption is to replace an older heating and cooling system with one that is Energy Star rated. HVAC systems that feature the Energy Star use approximately 20 to 30 percent less energy than federal standards require. Combined with proper weatherizing and insulation, an Energy Star rated HVAC system has the potential to slash your winter energy bill in half.

Tips On Keeping Your Home Energy Costs Down During Your Winter Vacation

As you pack for your holiday vacation, you should turn your attention toward some ways to keep your energy costs down once you leave the house. Whether you will be gone for just a few days or weeks, you can save a decent amount of money when you make some simple adjustments to certain appliances in your home. When you follow these tips, you might be pleasantly surprised when you see your next utility bill.

Unplug All Appliances

The easiest way to keep your energy costs down while you are out of town is to unplug all or most of the appliances in your home. That’s because even items you are not using can take up energy just by being plugged in. You can start by unplugging large appliances, such as your television, gaming consoles, stereos, computers, and lamps. But even smaller items can use some electricity while you are gone, so be sure to unplug any electric razors, phone chargers, and small kitchen appliances in your home.

Lower the Temperature in Your Home

In the winter, you might be used to using your heater, but remember to turn it down when you leave the house for more than a couple of days. The recommended temperature for when you go on vacation is about 50 degrees. This is low enough to keep your energy costs at a minimum, but high enough to prevent your pipes from freezing while you are gone. Of course, if you go on a vacation when it is hot outside, be sure to increase the temperature at which your air conditioner is set. Putting at around 85 degrees is a good way to save on energy.

Reduce the Temperature of Other Fixtures

Your heating and cooling systems are not the only fixtures in your home that you should adjust before you leave for vacation. You should also turn down your water heater. After all, you won’t exactly be needing hot water in your house while you are gone. In addition, you should turn down the temperature of your freezer and refrigerator. If you plan to be gone for weeks, you might even want to clear the food out of the refrigerator completely since much of it could spoil while you are gone. Then you can clean the fridge and unplug it until you return, saving a good amount of money when it comes to electricity.

Use Timers When Possible

If you plan to leave a few lights on at your house to make it seem like someone is home, consider getting timers for those lights first. This way, they will only come on at night so you do not have to leave them on during the day. Additionally, if you have a programmable thermostat, plan to set your heater to a warmer temperature the day you return home, ensuring that your house will be comfortably warm when it really counts.

Of course, you can also keep your energy costs down at all times by making sure your heater and air conditioner are working properly.

Keeping Your Home Cozy and Warm Through the Holidays

Nothing can cast a chill over your holiday gatherings faster than a faltering or failing heater. Ensuring that your heating system functions at peak performance plays an important role in your holiday preparations. Even a well-maintained heater, however, can’t operate at optimal efficiency when gaps, cracks and holes in the building envelope allow cold air to infiltrate inside. The following tips can help keep your home warm and cozy throughout the winter season and lower your heating costs as well.

Preventive Heater Maintenance

Scheduling preventive maintenance is the most cost-effective thing that you can do to make certain that friends and family members are comfortable in your home during the holidays. Heating equipment consists of complex parts and components that must work in perfect synchronization with each other to operate efficiently. A seasonal heater tune-up keeps everything running in peak condition. Any potential problems can often be fixed on the spot, allowing you to avoid the expense of a future emergency repair.

Proper maintenance is particularly important for fuel-burnings furnaces and boilers. A number of harmful by-products are created during the combustion process that can corrode parts and cause dangerous fumes to leak into your living spaces. Professional maintenance helps protect the health and safety of your loved ones.

Air Infiltration Solutions

The last thing that you want when sitting down for a holiday dinner is a cold draft sweeping through the room. Air infiltration not only compromises your comfort but forces your heater to run longer, driving up your heating costs. Use these tips to plug up the air leaks:

  • Weather-strip windows and doors.
  • Use caulk to seal gaps around utility conduits in exterior walls.
  • Seal up holes in attic floors
  • Ensure that your attic is adequately insulated.
  • Keep your fireplace dampers closed when not in use.
  • Have your HVAC ductwork pressure-tested for leaks.

Replace Outdated Heaters

Today’s modern heaters are not only significantly more energy efficient than older models but deliver a higher level of comfort as well. Features like variable-speed fans allow HVAC systems to react and adjust to heating demands automatically. Instead of intermittent blasts of hot air, you’ll enjoy an even distribution of gentle warmth while conserving energy too. If your heater is more than ten years old, chances are you’ll save money with a high efficiency replacement.

As a family owned and operated business, Lex Air is committed to ensuring that your loved ones enjoy the highest level of comfort during the holidays and in every season. Whether you need maintenance services, an emergency repair for a broken heater or a high efficiency replacement, you can count on our HVAC experts for affordable and effective solutions.

How to Determine When it’s Time for AC Replacement

Most homeowners have paid a lot of money for their home’s air conditioning system. It only makes sense to want to get the most out of an HVAC system.

Homeowners would like for their air conditioning system to last as long as possible, and they want to avoid AC replacement Dallas. The longer the HVAC system lasts; the greater the ROI. Unfortunately, all good things come to an end.

Home appliances might last for many years, but eventually, they’ll need to be repaired or replaced. Fortunately, homeowners can watch for some simple signs, which indicate the need to replace the HVAC system.

SEER Rating

All air conditioners have what is called a SEER rating. About seven years ago, all air conditioners were required to have a SEER rating of 13 or greater.

However, many homeowners have air conditioning systems that are much older than seven years. All homeowners who own an AC system that has a SEER rating that is less than 13 should have their AC system replaced.

Systems that have a SEER rating less than 13 are using too much energy and costing homeowners money. By having their AC system replaced, homeowners can help the environment and pay less money for energy.

Too Old

A number of homeowners have an air conditioning system that is 15 years old. Some people own a system that is even older than that. On average, AC systems have a lifespan of about 15 up to 20 years. However, to continue operating for 15 to 20 years, air conditioners must receive proper maintenance.

Over time, many new air conditioning systems have been created, and most modern systems have excellent energy efficiency and use much less energy than older models. Homeowners who own an air conditioning system that is 15 or older can benefit greatly from having the system replaced.

R22 Refrigerant

New regulations prevent the use of R22 refrigerant. Unfortunately, this type of refrigerant has a negative impact on the environment, so by 2020, R22 will totally banned.

The price of R22 refrigerant is skyrocketing, so homeowners who own an air conditioning system that uses this type of refrigerant should consider getting a replacement. By having their current R22-based HVAC system replaced, homeowners can save money and help protect the environment.

Rising Energy Costs

Another sign that it’s time to replace your air conditioning system is an increasing energy bill. Although the average price of energy is on the rise, homeowners should be able to tell if it’s their AC system that is causing them to pay more.

If a unit is receiving proper maintenance, it shouldn’t cause the energy bill to rise every month. If your energy bill is rising every month, it could be a sign that you need to have your air conditioning system replaced.

Less Comfort

The purpose of an air conditioning system is to make a home comfortable. It filters air and maintains a comfortable temperature. Homeowners who find hot or cold spots throughout their home should consider getting their AC system replaced.

However, before having the system completely replaced, it’s important to make sure it’s getting proper filter changes and similar maintenance. These are just a few of the signs that might indicate it’s time to replace the AC system.

How to Increase Your Air Conditioner’s Efficiency

Air conditioning is something that is hard to live without. In Earth’s hotter regions, some people could potentially die without air conditioning. Although it’s something that many homeowners take for granted, air conditioning is crucial for a comfortable lifestyle.

We are the best Dallas air conditioning company around, and we provide a number of services that will keep your AC system running smooth. Although air conditioning can seem like a boring topic, there are many things homeowners don’t know about it.

Removing Dirty Filters

It’s a good idea to have us regularly replace your AC’s dirty filters. There are many reasons why an air conditioner might be running with reduced efficiency, but one of the main reasons is dirty filters. For both window and central AC units, filters should be changed monthly, which is a service that we provide.

However, some AC systems utilize a washable type of filter, so these filters just need to be cleaned. It’s important to understand your filter’s MERV, which is a number between 1 and 12. A higher number indicates that your filter provides great filtration.

Problems with Leaks

Many HVAC systems have duct leaks, which can greatly reduce system efficiency. In many situations, we’ve seen air duct leaks cause a 30 percent reduction in system performance. A window air conditioning system is notorious for being very hard to seal.

To discover leaks, we might use what is called the smoke trick. Your air conditioning system could be leaking massive amounts of air. We can fix duct leaks and other problems that rob your HVAC system of its performance.

The Power of Timing

One of the ways that we help our customer is by installing a timer. Many homeowners make the mistake of allowing their AC system to constantly run at full power. It doesn’t make sense to have the HVAC system running while at work or on vacation. A timer is the perfect solution to this problem.

More specifically, it’s a thermostat that makes it easy to dictate when an HVAC system turns on or off. Many modern window AC units have a programmable thermostat, so it’s quite easy to set the timer.

Shrubs Costing You Money

An HVAC machine’s condenser and compressor are usually located on the outside of a home. Most homeowners don’t know that there should always be about two feet of empty space around the compressor. Leaves, tall grass, hanging branches and shrubs can get too close to the compressor.

When there is not enough empty space around the condenser, the unit cannot function efficiently, and in the end, this ends up costing you money. Many homeowners like to build a screen around the compressor unit.

Having a compressor installed in a location that receives direct sunlight can reduce efficiency by 10 percent. These are some bits of information that most homeowners don’t know. If you need help applying this information or want to find out more about our services, call us today.

Energy conservation is the reason that the Environmental Protection Agency (EPA) recommends that home and business owners have their AC equipment checked and serviced at least once each year. One EPA study found that well-maintained HVAC systems use an average of 15 to 20 percent less energy than neglected systems.

Regular care not only significantly reduces your monthly cooling costs but offers you long-term savings as well.

How To Find A Great Air Conditioning Repair Technician?

How To Find a Great Air Conditioning Repair Technician?

When summer rolls around, you finally turn on your AC after almost three months of inactivity. If you are lucky, your AC will come on immediately. But…there is a very good chance that the AC will just not switch on or it will turn around and spit out a substantial amount of dust right into your face! Ideally, most AC manufacturers recommend biannual maintenance check-ups of all AC models to ensure that they work effectively for a long time. However, that means you will have to find a contractor who will maintain and repair your AC regularly.

Where to find local AC repair Carrollton contractors?

• Local hardware stores — Most local plumbing and spare part stores will have good contacts with local AC people. As a result, we suggest you talk to the shop proprietor and find out whether any local contractors will visit your home to service and maintain your air conditioners regularly.

• Check with the parent company — If you know the model and brand of the cooling system of your home, you can inquire with them directly. Large companies usually have service departments that are open 24 — 7. We suggest you call-up the customer service number or the toll free number and request a technician who will work on your unit. Most companies will send their technicians over but you might have to sign a service contract or a maintenance contract with the company for a minimal fee. The company will then send service technicians over regularly to evaluate your AC and ensure that it’s in working order. If your machine is under warranty, then these services are completely free.

• Check websites — Most local contractors will have their own websites by which you can contact them directly.  However, do be careful as there are several different models of ACs and it’s not necessary that the technician will be able to deal with every model. Collect the addresses of the contractors and then make sure that you ask detailed questions about the work you want done.

• Inquire with municipal authorities — Local builders and architects will always know the names of knowledgeable employees who will be able to maintain or repair your ACs. As these personnel have completed several projects, they already know local codes and rules and they will be able to work with several different types of AC models.

• State databases — All contractors now have to register themselves with state boards.  As a result, we suggest you check national databases to ensure that you find a local worker who will ensure that your appliances are in top order.

Once you have found the technician you want, it necessary that you check their credentials. Make sure that the technician you choose is licensed to work in your city. They should also be covered with workers insurance and liability insurance to ensure that they are protected while they work on your ACs.  Ask for proof and get a complete written quote before the work begins.
