Should I Replace the Air Conditioner and The Furnace Together?

The heating and cooling devices inside our home require a considerable investment. Thus, replacing an air conditioner and a furnace at the same time not only sounds expensive, but it actually is. After looking at this from a different perspective and after talking to many homeowners who have replaced their air conditioner and furnace together, we concluded that replacing both the device at the same time may be expensive. Still, it saves you money in the long run. But the question is if your air conditioner has given up, but your furnace can be fixed with heating services in Wilmington, DE should you consider replacing your furnace too?

Replacing the Air Conditioner and the Furnace at the Same Time

An air conditioner runs for 15 to 20 years, whereas the average lifespan is 15 to 30 years. Thus, a furnace works twice as long as an air conditioner. And you might be tempted to postpone the replacement of your furnace if it’s not too old. However, if you are replacing your air conditioner, you must consider changing your furnace to contribute to the entire HVAC system’s efficacy.

When Must You Replace the Air Conditioner and The Furnace at The Same Time?

While it is not necessary to replace your air conditioner and furnace at the same time, you may consider replacing it if the following contemplations are applicable in your case:

Your Furnace Is More Than 15 Years Old: If your furnace is 15 years old, it will definitely start losing its efficiency over time. If you are replacing your air conditioner, you can replace your 15 years old furnace too. A new furnace will increase your home comfort and will help the entire system to work efficiently.

If the Installation Is Complicated: In many cases, it is difficult to replace your air conditioner alone, due to the common electrical wirings. And the HVAC technicians may find replacing both the systems to be a better choice.

If You Want to Avoid Repairs and Replacement for A While: A new furnace will keep the need for heating replacement in Wilmington, DE, at bay. A new air conditioner and furnace together will keep your home comfort uninterrupted.

When Don’t You Need to Replace Your Air Conditioner and Furnace Together?

There are many instances when you must consider waiting to replace your furnace at the same time as your air conditioner, such as:

A furnace lasts for 20 to 30 years, and if your furnace is less than 10 years old, replacing the system may turn out to be a wastage of money. But your air conditioner needs to be changed every 10 to 15 years. And if your air conditioner has reached its maximum lifespan, you must replace the AC alone.

It’s always better to talk to an expert for professional suggestions before making a final decision. Talk to D&T Heating and Cooling to inspect your air conditioner and furnace and determine if you need to replace both the system. Contact us to get free estimates for replacement and other heating services in Wilmington, DE.


Some Heating Mistakes That Are Raising Your Electricity Bills

The coldest months are almost here, and there are many things you can do to increase your furnace’s efficacy. After all, your furnace accounts for the largest part of your monthly utility bills. But while you are putting every effort to save on your energy bills, some misinformation may lead you in the opposite direction, and you may end up needing pricey furnace repair in Wilmington, DE. Before you start believing some wrong information to be accurate, here we are to help you avoid some common mistakes to not spend anything over what’s necessary.

Top 5 Heating Mistakes Spiking Your Utility Bills

There are many mistakes that the homeowners commit while heating their houses. But we have listed the most common and top 5 mistakes responsible for raising your electricity bills.

Heating an Empty House

If you stay out of your home most of the time or unavailable during the weekend, don’t heat your house the way you do when you are present at your home. This mistake is made specifically when you rely upon a manual thermostat for controlling your room temperature. And you can deal with this mistake just by installing a programmable thermostat replacing the old one. A programmable thermostat will save money on energy bills while making your system work less and keeping it safe from pricey furnace repair in Wilmington, DE.

Not Changing the Air Filters

When your furnace air filters are clogged or dirty, they can make your furnace work harder than usual. All HVAC companies in Wilmington, DE, suggest cleaning your air filters frequently and to change them every 30 to 60 days. If you avoid this simple step for long, you waste energy instead of using the power supply sensibly.

Ignoring Drafts and Leaks

Don’t underestimate the amount of heat you are losing due to leaks and drafts. If your France is generating warm air, but if you can’t feel the warmth consistently, it is a sign that your home is losing the warm air. As a result, your furnace will work harder than it should to maintain the comfort inside your home. And you will notice a drastic rise in your electricity bills. Seal the gaps from where cold air is coming, or warm air is leaking out.

Using Your Fireplace for More Heat

Well, it may seem like a great idea, but it is not. When you use your fireplace along with the furnace, you do more harm than good. The heated air will go straight out of your house through the chimney, and cold air will enter from outside. It will make your house colder and will force your furnace to work harder.

Neglecting Regular Furnace Repair

You need to arrange regular heater repair in Wilmington, DE, to maintain your system to work efficiently. But if you miss regular checkups, remember that even a small undiagnosed issue in your furnace may turn into a costly maintenance problem.

air conditioner

How an Air Conditioner Works?

An air conditioning system is not a luxury anymore, but it is necessary for many homeowners in the modern world. The global temperature is rising every day. Only a central air conditioner can provide some respite from the blistering heat and humidity in such a situation. There are various options to choose from while it is about cooling your homes, and each of those options has unique pros and cons. An air conditioner is one of the most complex and essential systems in your home. A professional air conditioner repair in Wilmington, DE, can help you deal with your HVAC system problems. But you should understand the basics of the system.

Knowing a bit about your HVAC system helps you to perform some types of maintenance of your own. Whenever you spot some imminent problems, you can reach an expert for help.

What Is the Working Mechanism of An Air Conditioner? 

If you want to know how an air conditioner works, it’s pretty simple. The system uses energy to cool down the air inside your house and blow the warm air outside your house. The working of an air conditioner is based on the physics of evaporation. But in an air conditioner, the evaporation occurs within a closed-loop, and a chemical compound named “refrigerant” is converted from liquid to gas and back to liquid in continuity. The refrigerant is easily convertible to gas in relatively low temperatures as compared to water. The most widely known refrigerant is actually Freon, which is a trademarked combination of several components.

What Your Air Conditioner Does Indoor?

The cooling process of your air conditioner takes place within the air handler unit, which includes the evaporator coil. The evaporator coil helps turn the liquid refrigerant into a gaseous form, and the operation takes place to remove the heat. The central air handler then blows the air taken from your home over the evaporator coil while cooling it. The cold air is then blown into your house and reduce the temperature.

What Your Air Conditioner Does Outside?

Once the evaporation process is finished, the refrigerant moves through the loop system to the condenser unit. The condenser unit experiences a compression that squeezes the gas’s volume and converted back to a liquid form. The cycle of the transformation repeats through the system. Just like the evaporation, the compression also creates heat. The compression unit, which is established outside, emits the heat via a set of condensing coils. And the big fan we just on the top of the outdoor unit helps blow the excess heat out into the air.

There are several types of air conditioning systems to choose from. you can contact AC Contractor Wilmington, DE. It is challenging to learn about a complete air conditioning system in just one day. It needs years of experience and in-depth research to know more about your air conditioner. With time you get to know a lot of things about your AC unit. There are many minor repair work that you can handle all by yourself at home without professional guidance, such as changing or cleaning your air filters, changing the thermostat setting, unclogging your outdoor unit, etc. If you need professional help for air conditioner repair in Wilmington, DE, call D & T Heating and Cooling.


Why Is My Air Conditioner Running Constantly?

Is your AC running constantly without cycling on and off as frequently as it should? When the temperature soars, it’s common for air conditioners to run continuously. But if the non-stop AC cycle is accompanied by an increase in the utility bill, you may want to consult an AC contractor in Wilmington DE.

The problem may seem benign at first but can cause long-term damage to the unit if it remains unresolved. There are many factors responsible for this phenomenon. Some of the common ones are as follows:

Variable Speed AC

Variable-speed air conditioners are different from single-speed ACs as they keep running at a lower capacity to keep your house cool. They offer a wide range of speeds but are very energy efficient. Therefore, if your air conditioner is running constantly, you may want to check if it’s a variable speed AC. If this is not the reason, you should contact a qualified HVAC company that offers the best air conditioner repair in Wilmington, DE.

Undersized Air Conditioner

If your air conditioner is undersized, it will experience extra strain to produce desirable cooling. The right size of an AC as per your requirement is determined by your home’s size and layout. If the AC is too small, it will have to run constantly to meet the thermostat temperature. If the issue not resolved quickly, it can cause overheating, putting the internal components at the risk of premature wear and tear.

Oversized Air Conditioner

If you have recently got your air conditioner replaced or installed, chances are that you might have opted for an oversized unit. This can also lead to short-cycling, which causes hot and cold spots in the house and makes the air muggy. In such a case, it’s good to rely on professional advice. Let an AC contractor in Wilmington, DE diagnose the exact problem with your system.

You would be surprised to know that more than half of the heating and cooling systems are installed improperly in the United States. Therefore it is necessary to trust the experts.

Lack of Maintenance

Experts suggest that central air conditioners should be inspected at least once a year in order to keep them efficient and functional. The process of AC maintenance includes deep cleaning of the unit, which prevents the build-up of dust and debris. If not cleaned, debris restricts the airflow and makes your air conditioner run incessantly to cool your house.

Ignoring timely maintenance of your heating and cooling system often leads to cost-intensive HVAC repair in Wilmington, DE. Therefore, contacting experts for AC service immediately is a smarter choice.

Similarly, there are several other technical problems that can result in air conditioners running continuously. These include clogged filters, dirty coils, faulty blower motor, and extreme humidity.

5 common household products that pollute the air in your home

People often feel safer indoors when pollution levels outside turn alarming. However, did you know that the U.S. Environmental Protection Agency has revealed that indoor spaces are nearly two to five times more polluted than the outside environment? The major sources of indoor pollutions are some common household products.

Poor indoor air quality means an increase in allergy-triggering dust mites, molds, and pet dander. This can be troublesome especially for those with existing health conditions such as Asthma and other respiratory ailments. With people spending almost 90 percent of their time indoors, this may sound scary.

The indoor pollution is likely to get worse during the winters because homeowners tend to keep their windows sealed, blocking the ventilation. So being aware of the common indoor pollutants can help you keep impurities in the air under check.

Common Indoor Air Pollutants


Your house may appear tidy after deep cleansing with scented cleaners but it causes a lot more damage to your indoor air quality than you can imagine. This is because of the higher volatile organic compounds (VOCs) in these products. To prevent this, you can use natural cleaners such as vinegar and baking soda to clean your house.


Paints are known to emit gases, exposure to which can cause breathing issues. It is advisable to dispose of your empty paint cans as soon as possible. If there’s a need to store them, do not keep it inside your house or garage. Choosing paint with lower VOCs might also help address your concerns.

Aerosol Sprays

Aerosols are notorious for contributing to not only indoor pollution but also outdoor air pollution. Aerosols are minute particles or liquid droplets in the atmosphere. These fine droplets are easy to inhale while breathing and can cause serious health concerns. Substitute items like hairspray with non-aerosol alternatives.

Air fresheners

Your air freshener is a bottle that contains nearly 100 chemicals, which are released into the air with a single spray. This can trigger migraine and asthma attacks. Keeping windows open is an effective alternative to keep fresh air coming in. Otherwise, unleash your creative side to try several DIY products that produce similar results without causing pollution.


Who doesn’t use candles to light up the mood and warm up the ambiance? But candles release a chemical compound named formaldehyde, which is harmful to health. It contributes to the indoor particulate matter and can even cause lung inflammation.

Sometimes it’s just impossible to avoid air pollutants completely. Therefore, the situation calls for a much more efficient mechanism to improve indoor air quality. These include the installation of a ventilation system or seeking HVAC repair in Wilmington, DE if you sense an increase in indoor air pollution.

Did you know that the right level of temperature and humidity is also important in reducing indoor contaminant levels? An HVAC system allows you to monitor these parameters. D&T Heating and Cooling provide a wide range of air purifiers and excellent ventilation services.

If you are concerned about your indoor air quality and its impact on the health of your loved ones, call 302-838-6905 to request a service estimate. We also offer the best air conditioner repair in Wilmington, DE.

Tips on how to avoid costly air conditioning repair

Tips on how to avoid costly air conditioning repair

Air-conditioning is one of the most expensive investments anyone has to make. And if there is a problem with it, everyone stops. Due to global warming and health issues, we humans can’t tolerate the excessive heat we are experiencing these days.

So you bought an air-conditioning unit. How can you be sure it will run continuously at its maximum capacity with minimal power costs? Below are some tips that came from old school engineers and new innovative technologies guaranteed to let you avoid expensive air-conditioning repair:

Keep the A/C unit clean – Small window type A/C units have filters at the front. It is easy to clean those. It will surely help if you clean them every month. Not only you are maintaining the air quality of your room, you are helping your A/C blower to move more freely and be cool as well (clogged fans may overheat)

Provide a maintenance program – This is another important decision that you must perform if you have bought an A/C unit. Qualified maintenance personnel will thoroughly clean the unit and even check the parts for wear and tear. This is called preventive maintenance. This is very important if you have large centralized units installed. For small window type units, you can do it every 6 months if you use your A/C always.

If your A/C is old, change it – Some of us are simply nostalgic when we have these old A/C units working for us. And some does not have the time to replace it also. But whatever the reason is, if it is over 20 years old, better change it completely. Yes it is expensive and a time consuming process. But we are pretty sure that the new unit will run for another 20 years, and, it will save more on power costs. One more thing, if your old A/C unit has broken parts, chances are, it is already obsolete and replacing them with replacement parts is big gamble.

Observe, observe, observe – Some clients will not care after their A/C unit is installed. As long as it keeps them cool, that’s enough. But we have to be mindful on our A/C unit as it is the only equipment that is installed by another person, and it is different from LCD TV’s or refrigerators where we can plug and use it on our own. So the only thing for the client to do is to observe very carefully. After the unit is installed and under operation, he or she must try to check for any abnormalities like sound, water droplets, improper cooling or heating, even vibration. So if you notice something, report it immediately to your contractor/installer, no matter how small it is.

Assign a trained user or operator for your A/C unit – large corporations assign an operator to operate their A/C unit. This can be done on our homes as well. You can assign someone from your family which is trained by your installer to operate the A/C unit. A few clicks with Google can enlighten us on how to operate our A/C unit also. The one the control’s the A/C, which is the thermostat, may become defective if it is not used properly, and this small device is costly, and contractors also charge high fees on its installation.
