How Will You Know If Your Heat Pump Is Low On Refrigerant?

How Will You Know If Your Heat Pump Is Low On Refrigerant?

A heat pump is a widely-used heating device in Rockwall, TX. However, the most common issue accompanying its efficient operation is refrigerant inefficiency. So, how will you know if your unit is low on refrigerant?

Watch out for these warning signs:

Low Heating and Cooling Output

The refrigerant plays a vital part in the operation of your heat pump. This heating system provides heat during winter and cool air during summer by simply reversing the flow of the refrigerants. If you notice a drop in the heating or cooling output of your device, the first thing that you should check is its refrigerant level. If there is low refrigerant, bring in the experts for an immediate solution.


There are a lot of factors that can cause an ice buildup in your system. One of them is due to refrigerant insufficiency. Your heat pump unit needs the proper amount of refrigerant to absorb heat in the evaporator coil. If the refrigerant leaks and the heat are not absorbed completely, ice will develop in the system.

Gurgling Sound

Weird noises coming from your heat pump tells you that something is wrong with the system. Each sound corresponds to a certain problem in the components. If you hear a loud, gurgling noise when your unit is on, there can be a refrigerant leak in your system. That is the sound of the air bubbles produced when the refrigerant flows out.

Pooling Liquid

Take time to check the area of your heating system. If you see pooling liquid around the equipment, it means you have a refrigerant leak. In that case, you should call the pros for a quality heating service.

What Does an HVAC Expert Do With Leaking Refrigerant?

Many people would think that the solution for refrigerant insufficiency is simply filling in the right amount of refrigerant, but it is not. A professional HVAC technician knows that the first step to completely fix the issue is by finding the leaks and sealing them before putting in the right amount of refrigerant.

If you suspect refrigerant leaks in your heat pump and you’re looking for a dependable HVAC contractor in Rockwall, TX, contact us at Rockwall One Hour Air Conditioning and Heating. We deliver fast, high-quality, and reliable repair, installation, and other heating services. You can count on our skilled professionals to be there on time, providing guaranteed work.

Homeowner’s Guide: Carbon Monoxide Poisoning & Prevention

By admin,

Every year, approximately 50,000 people in the U.S. are hospitalized due to accidental carbon monoxide (CO) poisoning. Because CO is colorless, odorless, and tasteless, it’s almost impossible to detect it with our senses. It can kill you before you know it.

But with the right knowledge, this deadly gas is entirely preventable. Read on to learn more!

What Causes Carbon Monoxide in Your Home

Running a car’s engine in an enclosed space or any household appliances that use gas, oil, coal, and wood are potential sources of CO. This happens when the fuel is not burned thoroughly.

Why is CO so Dangerous?

In reality, it only becomes harmful when breathed. Why? It replaces oxygen in the blood and interferes with the transport of oxygen needed by our body. It deprives your heart, brain, tissues, and other vital organs of oxygen. Carbon monoxide poisoning can lead to loss of consciousness, suffocation, or DEATH if left unattended in a confined area.

How to Recognize CO Poisoning

A few of the most common symptoms are headache, dizziness, weakness, nausea or vomiting, chest pain, vision problems, confusion and drowsiness, and irregular heartbeat and chest pain. You may also experience “flu-like” symptoms.

CO Poisoning Prevention Tips

  • If you have a fireplace or devices that use gas, oil, coal, and wood, or in doubt of harmful gas leaks, consider installing CO detectors in your home. Make sure to maintain these devices regularly for best performance.
  • Perform regular HVAC maintenance. Have your comfort system, water heater, and any other appliances serviced by a professional to make sure they operate within the safety levels and without the risk of leaks and CO poisoning.
  • Keep vents and ducts free of debris. Keep your home ventilation working at all times especially during the winter or after a storm.
  • Avoid running your car’s engine in a closed space. Proper ventilation is absolutely critical to avoid CO poisoning. Remember, even if you leave the garage door up or some windows open, gas can quickly build up to toxic levels.

Guarantee the safety of your family and protect what’s precious to you by getting rid of the silent killer (carbon monoxide). One way to prevent CO poisoning is to keep your comfort system working at the utmost efficiency.

Tips For Staying Warm And Cozy Indoors During Winter

By admin,

Cranking up your thermostat is one of the best ways to stay warm and combat wintertime. But it’s not the only way! If you’re looking for some budget-friendly ways to keep warm and cozy this winter, you’ve come to the right place.

One Hour Air Conditioning and Heating offers a few helpful tips to help you deal with the cold while staying comfortably warm and cozy indoors.

It’s faster to warm yourself

Based on studies, it is much easier to change a living body’s temperature than room temperature. Keep this in mind: instead of relying too much on your system, it’s better to practice simple yet effective ways to combat the cold.

Try putting on another layer of clothing, a blanket, a hat, or perhaps enjoy a cup of coffee or tea whenever you feel cold while enjoying some quality time with your family members.


If you stay inside a lot during the winter, remember not to stay still. Try to move! Get up and walk around a bit, do house chores, or simply do some stretching, so as not to feel the extreme cold. Try to take regular breaks to move and stretch so your body will stay active and warm.

Heat your bedroom, not the whole house

In the coldest night, it is better to heat only a portion of your home like your bedroom for more efficient and inexpensive heating. It might be better to heat just the bedroom and shut the door to keep the heat in.

Reverse ceiling fan direction

By setting your ceiling fan to its “winter” mode and reversing the direction of the fan blades, you can create an updraft that will help move the warm air.

So what are you waiting for? Take advantage of the warming effects of your ceiling fan. It will help circulate the air to improve indoor air quality while keeping the warm air inside.

Use a programmable thermostat

Not only will you have total control of your home’s comfort, but you will also be able to enjoy an increased lifespan of your system and lower energy bills. Stay cozy on schedule, so you will never suffer from a home colder than the outside.

Whether it’s time to have a new heating system installed or to have repairs on your furnace, you must work with the best professionals who can truly understand your needs. At One Hour Air Conditioning & Heating, we care about the comfort of your home. Contact us today.

Common Causes of Poor Indoor Air Quality

By admin,

Since then, air pollutants have been a problem for every home. What’s worse? Exposure to a high concentration of these pollutants can cause eye irritation, nose and throat irritation, dizziness, headaches, fatigue, and other serious health issues.

But by being able to identify the causes of indoor air pollution, you can make a big difference in your overall comfort and health. Discover the common causes of poor indoor air quality and learn to avoid them for a cleaner and safer home.

Radon Leak

If your home has cracks or holes in crawlspace or basement, this odorless gas could find its way in; therefore, increasing the risk of respiratory ailments to you and your family. It doesn’t matter if your home is new or old, homes of any age can potentially be affected.

Radon is a radioactive gas that commonly comes from the ground. Since it is not easy to detect, it takes a particular test to know if your home is exposed to radon. Fortunately, test kits are available at a reasonable price through your HVAC contractor. They can assist you with the procedure, so contact us today to schedule an appointment.


The organic compound known for its use as an embalming fluid that is harmful to humans is often found in the adhesive of carpets, furniture, and various household products. Once released into the air, it can irritate your skin, eyes, nose, and throat, which may cause breathing problems. Formaldehyde is a dangerous chemical that contributes to poor indoor air quality in your home. One way to eliminate it is by using appropriate air purifiers.

Cigarette Smoke

Based on studies, a cigarette stick contains about 200 poisonous elements that go directly to your body’s system once inhaled. Simply saying, cigarette smoke is enough to make you ill. But, you can limit your exposure to these toxic elements by using air purifiers or avoiding smoking completely.

Natural Gas and Stoves

Harmful gases like carbon monoxide (CO), nitrogen dioxide (NO2), and even a bit of formaldehyde oppose the convenience of natural gas. These chemicals can trigger respiratory problems, make you prone to illnesses, and even depression. Exposure to low levels of natural gas may seem harmless, but long-term exposure can be detrimental to your health.  

Household Cleaners and Disinfectant

What do you use to clean your home? While it’s important to keep your home clean, the items that you use might be the cause of why your IAQ is poor. Many of these chemicals, if not correctly used, can contribute to a variety of health problems, including headaches, asthma, and respiratory-related illnesses. So, the moment you use them in your home might be the same time it contaminates the air you breathe.

Soot, Smoke, and Fireplaces

According to a study, it is because of soots that more than half of all children under five years old die due to pneumonia. Using wood or charcoal to heat your home may be a practical way to stay warm, but doing so also allow harmful substances in your indoor air.

Choose a more efficient heating method powered by electricity, natural gas, propane, or fuel oil. Avoid health hazards by modernizing the way you bring comfort to your home.

Poor Ventilation

Without the right ventilation, your home can suffer from poor indoor air quality. It can also result in shortness of breath, headaches, and unnecessary fatigue. Proper ventilation invites more air inside, which can reduce places with high concentrations of smog and other harmful substances in their air.

Knowing the common causes of poor indoor air quality can help you take proactive steps in making sure your home stays healthy, comfortable, and safe. If you need help getting rid of these issues or want to have repairs completed on your home’s current system, our professionals have the know-how to meet your needs.

Are these HVAC New Year’s Resolutions on Your List?

By admin,

There’s no better way to welcome the new year than making sure you’ll be spending your time in a healthy and comfortable home. Start it right by including your heating, ventilation, and air conditioning system on your New Year’s Resolution list.

Make a good start with these important HVAC-related resolutions:

Get a Maintenance Plan

It is essential to have your system inspected by a professional at least once a year. Even if it seems to work fine, it’s better to be ready for anything rather than getting caught in the cold.

Promote a long life for your HVAC and keep it running in its best condition. A maintenance plan keeps your system from unwanted malfunctions, and as soon as issues arise, they’ll be prevented in real-time.

Commit to Filter Replacement

Your air filter traps debris, pollutants, and allergens circulating throughout your home. But in normal circumstances, your air filter will eventually become clogged due to dirt build-up. Without changing your filters, it’s impossible to solve this problem. Your system will struggle to do its job, causing discomfort and costly repairs.

This 2020, start committing to filter replacement to make sure your indoor air stays clean and breathable!

Invest in Air Purifiers

While air filters trap visible air pollutants that roam around your home, air purifiers get rid of what’s left—the smaller particles. They use a unique technology to catch bacteria and other airborne contaminants that may cause harm to your health. Make your indoor air cleaner and healthier with a high-performance air purifier.

Work with the Specialists

HVACs are highly sophisticated and sensitive systems that differ in makes and models. With this, you have to work only with certified professionals who know how to deal with your comfort equipment—the right way!  They have the expertise and experience to ensure your system will work at its best condition at all seasons.

Next time you need a technician to work on your HVAC system, make sure to get a specialist—the right person for the job.

Is It Time To Have A New Furnace This Year?

Is It Time To Have A New Furnace This Year?

Are you bothered by the operation of your furnace and feel like you need to buy a new one? We can help you decide with these tell-tale signs of a failing heating system. If you are experiencing these issues, it is definitely time to purchase a brand new unit for your Rockwall, TX home.

  • Old Furnace

Is your furnace more than 15 years old? If it is, experts recommend you do not delay the replacement. Old units are more prone to issues because the components are already worn out. Additionally, it may still be working but no longer as efficient as before.

  • High Energy Bills

Did you experience a sudden increase in your gas or electric bill this season? Your unit is most likely striving to give your home the right amount of heat. While repairs and maintenance services can help, they do not guarantee long-term solutions to your unit’s inefficiency. Save yourself from paying too much on your energy bill by replacing the unit once and for all.

  • Frequent Repairs

Are you having repair services and part replacements too often? If your unit is constantly in need of repair, its components are probably breaking down, and so is your entire unit. You should learn when to save your furnace by repairing it and when to let go and buy a brand new one.

  • Poor Comfort

Do you feel hot and cold spots or little to no heat in your home? An uncomfortable home is something you do not want to experience in the cold months, but this can be given to you by an inefficient unit that already needs replacement.

  • Poor Indoor Air Quality

Old furnaces tend to blow dirt, dust particles, and toxic air into your home. Not just that it’s frustrating to clean the house, it can also cause health issues to you and your family. If changing the filters and routine maintenance will not relieve your home from the effects of polluted air, replacing the furnace could be your last resort.

  • Loud Noise

Pay attention to the odd noises that your furnace creates. The rattling, squealing, humming, or popping sounds indicate that you have a failing unit. If repairs can no longer handle these noises, unit replacement is the best thing to do.

Looking at these signs, do you think your furnace needs replacement? If it does, give us a call at Rockwall One Hour Air Conditioning and Heating and let’s discuss your options. Aside from state-of-the-art equipment, we also offer the best financing options for you. Talk to our experts today!

Indoor Air Quality: Tips for A Healthier Winter

By admin,

According to the U.S. Environmental Protection Agency (EPA), your indoor air can become two to five times worse than outside air during winter. Cold air tends to make people unhealthy; the reason why it is essential to maintain clean and healthy air indoors.

Make your IAQ healthier this winter with these expert tips:

Keep Everything Clean

A good rule of thumb to remember is to keep all areas of your home as clean as possible, especially in the winter. Use non-toxic cleaning products whenever possible, so there won’t be any other potent chemical mixed in the air. If chemicals are unavoidable, make sure to thoroughly clean the area to prevent fumes in the room and on surfaces.

Also, do not forget to check the ducts and pay attention to your air filters because they are responsible for air circulation in your home. Keep them dust-free with regular cleaning to reduce the accumulation of dust mites, pollens, and pet danders.

Reduce Use of Wood & Gas

Homeowners rely on wood and gas for heating and cooking during the cold months while keeping the bills on the minimum. However, what most people don’t realize is that it releases potent toxins or chemicals into the air.

By being wise in cooking and reducing the use of your fireplace, you can reduce the amount of wood and gas toxins such as carbon monoxide, nitrogen oxides, and particulate matter (ash, dust, smoke) that are present in your indoor air.

Install Home Air Humidifier

If someone in your home is prone to allergies or asthma, using an air purifier may be helpful. With different types of air purifiers, make sure to get the right one.

Advanced technology enables some air purifiers to capture and eliminate even small pathogens like bacteria, viruses, and other pollutants. It can be an effective way to maintain a cleaner and healthier air at home in the cold season.

Achieve a Healthier Indoor Air Quality this Winter!

Maintaining a safer and healthier home is now easier than ever, thanks to innovations in the world of heating and air conditioning. Whether you need a new air conditioning system installed or your furnace repaired, you must work with the professionals who can truly understand your needs.

Rising Utility Bills

Replacing your system may seem to be a financial burden; however you’ll eventually understand how much money you could save by making the decision today.

You Feel Unsafe

Halloween Heating Tips for Homeowners

By admin,

At Rockwall One Hour Air Conditioning & Heating, we understand that high utility bills are way scarier for homeowners than spooky Halloween costumes.

As our Halloween treat, here are some tips in keeping your home cozy and comfortable this All Saints’ Eve:

Get Annual Maintenance

It is always a good thing to check your heating system regularly and not only when you experience problems. If you do not know how to do it, schedule a maintenance plan with a certified technician from a qualified HVAC company.

A thorough inspection will ensure that your system works in its optimum performance throughout the season. At the same time, it will also catch minor issues before they turn into bigger problems.

Stick to a Consistent Temperature

While there are different ideal temperature settings for a thermostat’s optimum performance, it is still a matter of personal preference. The perfect temperature for your home always depends on your comfort.

However, we advise you to avoid changing temperatures frequently as it makes it harder for your heating system to operate.

Change Your Air Filters Regularly

Maintaining a clean air filter does not only promote healthier air, but it also prolongs your system’s lifespan, saving you money in the process. It’s best to replace your air filter every three months or whenever necessary. Please know that clean filters can help you save you up to five to fifteen percent of energy.

Insulate windows before the winter

During the summer, it is advisable to keep your windows open so the sunlight can help heat your home. However, during the cold season, windows should be adequately insulated to prevent heated air from escaping, while keeping the cool air where it belongs. Doing so helps maintain an ideal humidity level and promotes better air quality.

At Rockwall One Hour Air Conditioning & Heating, we can help you evaluate your heating and cooling needs and choose the solutions that are best for your lifestyle and budget, whether it’s Halloween or not!

Best Ways to Prepare Your HVAC for Fall

By admin,

Homeowners in Rockwall, TX know that fall is the perfect time for some cleaning and maintenance. Particularly, they understand the importance of giving a dose of TLC to their HVAC systems during the cold season. No one wants a broken furnace in the winter, right?

We have prepared a list of the best ways to prepare your HVAC for fall.

1. Replace Air Filters

Whenever the season changes, it pays off to replace your air filter. A clean filter improves the efficiency of your system and decreases energy consumption for a lower utility bill. A clogged and dirty filter is a small issue, but when left unattended, it spells total doom of your HVAC. 

2. Seal Air Leaks

Leaks in your ductwork are among the most common cause of a high utility bill. Stop air leaks by sealing ducts with aluminum foil or mastik tape. Unsealed windows and drafts also cause air leaks, which explains why some rooms feel warmer or colder than the others.

3. Check Outdoor Components

Your outdoor HVAC also needs maintenance. Clear debris or any other form of obstruction around your unit and repair any damage that may hinder your system from working properly. Remove any combustible materials that may cause fire, such as dried leaves, twigs, and roots.

4. Get a Tune-up Service

Schedule a visit with a professional to make sure everything is working as expected. Your local technician will run tests to ensure that your system is ready for the long winter months. In most cases, your system needs a professional tune-up.

5. Consider a System Upgrade

An efficient HVAC system has a properly programmed thermostat, well-sealed ductwork, and adequate insulation. A system upgrade usually includes replacement of the old components or purchasing a completely new system. If you decide to invest in a new unit, talk to your local contractor for proper sizing. 

As a reputable HVAC company in Rockwall Texas, we often recommend purchasing a new system during the fall. For more HVAC maintenance tips, please visit our blog page or check us out on Facebook.
