Why You Should Hire a Qualified and Licensed Technician

The television shows and movies you are watching may have told you that you can fix your air conditioner all by yourself, but that is not very safe. DIY trends are taking off, and while there are some minor issues that you can fix yourself, it is always a good idea to call a technician. 

You can contact any HVAC companies in Wilmington, DEthat provide services for air conditioners. People in Delaware are very independent and do not usually like to depend on help from others. This is especially the case when it comes to their air conditioners. Add to that the harsh summer of the state, and you have very stubborn AC-owners. 

Most AC-owners do not know that there can be a lot of trouble if they do not get their ACs overlooked by a qualified technician. Here are some reasons why you should hire a licensed technician from an HVAC contractor in Wilmington, DE – 

They Are Trained For Everything

No matter what you or your air conditioner might throw at them, the technicians from HVAC companies in Wilmington, DE, are skilled to take care of everything. 

When a licensed engineer comes to your home, you can take a breath of relief. You can have the guarantee that your air conditioner problems are going to be solved. 

These technicians only get their licenses after passing several tests. These tests cover everything that could go wrong with an HVAC system so; you can rest assured. Make sure you are checking the qualifications and credentials of the technician you are hiring before you hire them. 

They Give Long-Term Solutions

An unlicensed HVAC professional often gives you the quickest method to manage an issue with your AC. Unfortunately, most of these methods end up harming your air conditioner more. 

Licensed technicians from an AC contractor in Wilmington, DE, will never go for a shortcut. They will ensure that the efficiency of your device is secured and you are safe from any possible threats. On the other hand, unlicensed technicians can leave your home at risk of electrical issues or dangerously high carbon monoxide levels.

They Are Insured

Insurance on technicians necessitates that cooling and warming experts get bonding and coverage of the compensation. This can be imperative to the AC-owner if anything turns out for the worse. 

Bonds are a kind of protection taken out by the worker for hire. If anything somehow managed to happen to your home throughout maintenance, these bonds cover the damage. An unlicensed and uninsured technician could leave you to pay repair bills without a cover. 

Moreover, if someone without insurance gets injured while the AC is getting repaired, you could have to cover their medical bills. If your technician is licensed and insured, they will carry a worker’s compensation coverage to save you from uncalled liability. 

To avoid such situations, you should hire a technician from us. D&T Heating and Cooling offers services of HVAC repair in Wilmington, DEand provides top-quality service. You can ring us up at (302)-838-6905 and tell us about your problem. Or you could write to us at

3 Reasons Why You Shouldn’t Neglect Your Air Conditioner Maintenance

The weather is finally cooling down, and we’ll get some relief. This is a tremendous comfort for most Wilmington residents, who, understandably, rely on their cooling systems significantly more than their heating systems.

However, it’s crucial to understand that, as a result of this, your cooling system is put under a lot of strain for almost nine months (and perhaps even longer during a “winter” heatwave). As a consequence, it may experience more wear and tear than is typical for an AC system. Regular maintenance by an authentic AC company in Wilmington, DE, will help you avoid costly repairs which may arise due to neglecting the maintenance of your air conditioner.

Here are 3 compelling reasons why you shouldn’t –

  • Avoid More Damage

As previously said, during the hot and humid summers, your air conditioner is put to a lot of work, resulting in a lot of strain. Consequently, considerable wear and tear may develop in only one summer season, particularly for old cooling systems or air conditioners that haven’t received adequate maintenance for over a year.

A loosened or worn-out piece, for example, may cause a pounding or clanging noise. It’s also likely that you have a refrigerant leak. On that topic, there’s a widespread misperception that refrigerant is meant to exit your system. That it’s something that needs to be refilled (what we call recharged) regularly. However, this is misunderstood, refrigerants are recycled in the system, and if it’s exiting your system, there’s a possibility you have a leak that needs to be repaired at the earliest.

If you ignore one of these problems, your cooling system will suffer.

  • Take The Easy Way Out

Isn’t it true that whatever troubles you’re having with your air conditioner now will be the same when the weather warms up again next spring? So you think you can simply put off having them fixed till then. This mindset puts you at danger of scheduling AC repairs at a time when HVAC professionals’ services are in great demand.

This implies that you may have to wait until a professional can come to fix your air conditioner. This is inconvenient if it is entirely broken down.

  • Provide Yourself With Peace Of Mind

When spring returns, harsher temperatures and heavy humidity may come solid and quick, making any delay seem like an eternity. When you schedule air conditioning repairs when you aren’t using your air conditioner as much, your comfort is much less likely to be disturbed.

This run-down of the three most fundamental reasons why you should not be neglecting your AC maintenance must have given you an idea by now of how it affects your AC system!

Now that you understand the need for timely air conditioner maintenance, if you’re looking for best-in-class services by the most efficient HVAC contractor in Wilmington, DE, feel free to contact D & T Heating and Cooling for all your heating & cooling needs!

DIY Guide To Unclogging Your Drain Line?

Several modern HVAC systems feature sensors that will notify you if your AC drain line gets clogged, allowing you to address the issue before water damage is caused. If your unit doesn’t have this feature, the drain pan will be full of water, indicating that the AC drain line is clogged. Before calling an AC company in Wilmington, DE, to help you unclog the drain, you can also try to unclog it by yourself. Continue reading to know-how!

Why Is My Air Conditioner Drain Line Clogged?

The AC condensate drain line eliminates the water produced when the evaporator in your air conditioner transforms the refrigerant from a liquid to a gas. As a result, algae and other dirt may add up over time. If you don’t clean your AC regularly, this might result in an AC drain line being clogged up. Need air conditioner repair Wilmington, DE. Contact D & T Heating and Cooling for best services.

Fortunately, unclogging the AC drain line is simple and can be done using items you most likely already have in your cleaning supplies. Here’s how to unclog your AC drain lines in an hour – 

  • Materials Required

  1. Rubber gloves
  2. A thin and stiff wire brush
  3. Duct tape
  4. A wet or dry vacuum
  5. Bleach
  • Instructions

  1. Before cleaning your Air conditioner, ensure it is turned off.
  2. Locate the drain line of your air conditioner. The majority of AC drain pipes are found outdoors, close to the condenser unit.
  3. Insert the stiff, thin brush in the drain line’s bottom. This may help to eliminate any clogs towards the drain line’s bottom. The AC drain line blockage will most probably appear further down, and you’ll have to take a bit more effort.
  4. Connect the other end of your wet or dry vacuum to the AC drain line. Duct tape is used to fasten it. Turn on the vacuum to eliminate any debris and, possibly, remove the clog.
  5. Retrieve the wet/dry vac and return indoors after roughly a minute of vacuuming. If the drain pan is clogged, vacuum this out and scrub it clean with soap.
  6. Find the vent tee. This is a pipe fitting that links the drain line from your air conditioner to the drainage tray. Disconnect the vent tee’s PVC cap.
  7. Use the stiff, thin wire brush to clear up any clogs in the AC drain pipe that are easy to reach.
  8. Wear your gloves and pour a one-cup bleach-to-one-cup-water solution down the drain pipe’s top. (When dealing with bleach, observe all safety precautions.) Wait thirty minutes before proceeding.
  9. Get a helper to stand out and keep an eye on the AC drain line to check if any water is draining. Working on your own? To test whether the AC drain line clog has been removed, position a bucket at the end of the drain line.
  10. Fill the vent tee with water and check to see whether it went all the way through the AC drain line. And you’re done!

If these techniques fail to clear your clogged AC drain line, it’s time to call D & T Heating and Cooling! Being one of the best HVAC repair Wilmington DE, they can clear your clogged AC drain line and check to make certain you don’t have any other problems.

6 Types Of Air Conditioners For Your Homes

Buying a new air conditioner is a significant investment in your home which should be carefully selected. But how to choose the best one for your house? It’s enough to confuse a grown man for evaluating your Air conditioner size, energy efficiency, cooling requirements, cost, quality, and all of the other elements of any air conditioning unit. We’re here to make the process simple and straightforward so that you can make the best decision for both your home and your money. You can even approach an HVAC company in Wilmington, DE, to save some time.

Keeping in mind that every consumer has different needs, there are six types of air conditioners – 

Window AC

Since window AC are available in various sizes, they would be useful if a single bedroom or a small area has to be cooled. If you buy a higher capacity window AC, it will be capable of cooling even a small apartment space. From the beginning, window AC has been identified as excellent cooling machines for smaller spaces and are the most popular air conditioner type.

Ductless split AC

Given the small interior units of these systems, every room has its unit used for either heating or cooling. Such AC is considered far more energy-efficient than some of the other available options in the market. It will get pretty expensive if you intend to place one indoor unit in each room for your entire home. 

Central AC

If you live in a big residence and want to cool several areas at once, you should use a central air conditioner. This type of air conditioner uses a split system that controls the air in your home via conduits. Such air conditioners are also called ducted systems. We highly recommend you consult with AC companies in Wilmington, DE, before purchasing a central AC because of its complex and costly nature.

Hybrid AC

Hybrid Air conditioners alternate between fossil fuel and electricity to minimize energy consumption. In hot summers, the heat pump works as usual by drawing heat from your house and distributing it outside. In cold winters, your hybrid heat pump system operates the other way around, draws heat from the outdoors, and re-distributes it inside.

Portable AC

As the name suggests, it can be moved from place to place. It can be placed standing on the floor, and it is easy to plug and play with. On the negative side, it makes a lot more noise than a conventional AC.

Geothermal heating and cooling

It is a new revolutionary technology that is gaining attention worldwide since it is an eco-friendly alternative to conventional HVAC systems that burn fossil fuels. This system simply transfers heat from the earth to your homes in winters. In summer, remove the heat from your homes and deliver it to the ground.

Although it is good to have the information, it is better to consult a professional HVAC technician before you make your move. D&T Heating and Cooling service is a reliable AC company in Wilmington, DE. Contact them at (302)-838-6905 for a consultation.

7 AC Installation Mistakes and How you Can Avoid Them

If you want your HVAC system to function smoothly, you must maintain it regularly. Inefficient or obsolete systems, as well as improper AC installation, can increase your energy expenditures by as much as 40 percent. D&T Heating and Cooling is a good AC company in Wilmington, DE, for installing your AC if you need professional help.

In this blog, you will learn about 7 such mistakes that you can avoid during the installation process of your AC – 

Wrong size of AC

Short cycling can occur when units are too large. Units that are too tiny, on the other hand, will have to work overtime to keep your home comfortable. The size of your AC is dependent on the area. To do so, multiply the room’s width by the room’s length in feet. Then you need to multiply this quantity by 25, as effective cooling requires 25 BTU for each square foot. This will provide you with the minimum required cooling capacity.

Lack of insulation

The coolant on the suction line must be insulated by the HVAC specialist who arrives to install your air conditioner. When there is improper insulation, the air conditioner’s efficiency suffers significantly. So, keep an eye out for such instances so that damages can be avoided. 

Wrong wiring

If the HVAC technician isn’t very experienced with installations, he might do shoddy wiring work, which could be dangerous and cause problems with the unit’s operation. Also, make sure there are no cables left exposed.

Improper placement

It’s essential to leave enough space around the outside unit from all sides. This provides proper airflow and, as a result, optimal operation. Ensure that your HVAC technician leaves the proper amount of space around the outdoor unit during installation.

Long coolant pipes

The coolant pipes that connect your air conditioner’s interior and exterior units should not be too long because this can make the air conditioner’s cooling cycle difficult to complete. This will also result in the compressor running continuously, using more energy than necessary.

Too much refrigerant

When pumping refrigerant into your AC, you must strictly adhere to the instructions. Adding excess refrigerant to your air conditioning system might severely damage it, costing you a lot of money. To be on the safe side, you should hire a skilled HVAC company in Wilmington, DE. Professionals are familiar with these procedures and will guarantee that your AC is set up correctly.

Improper ductwork

Air can leak out of your air conditioner unit if the ducts aren’t properly sealed. To prevent this, make sure your ducts are properly sealed with a good sealant. If you find a gap, the tape can be used as a temporary fix, although small amounts of air can still escape.

You could end up losing a lot of money if you make a mistake with your air conditioning installation. It is wise to book an appointment with trained HVAC technicians like D&T Heating and Cooling at, one of the best AC companies in Wilmington, DE.

Spring Maintenance for your Air Conditioner

Your HVAC system consumes the most electricity during summers. According to some reports, it accounts for about 60% to 70% of your energy bills. Regular maintenance of your air conditioner can save you a lot of money. And the best time for an AC check-up is in springtime, when HVAC technicians are pretty much unoccupied, unlike in summers. 

Some tips to help you do it by yourself – 

Replacing air filters

This can greatly affect the health and efficiency of your air conditioning system. After the air filter is obstructed, your air conditioner starts to utilize more energy. Change your air filter every month, particularly when you have dogs in your home. Dogs shed a lot of hair, and they tend to block the air filters.

Clear the condensate drain

A clogged drain pipe can overflow the drain pan of your Air conditioner. Drain pipes can be obstructed by dust, rust, fungus, and other waste. Add a solution containing 50 percent bleach with 50 percent water to your access point to ensure that your condensate drain is free from algae and mold. You could even purchase a solution available at any local hardware store or an AC maintenance company.

Remove obstructions

Ensure that the outdoor unit of your HVAC system is not clogged with branches or leaves. Remember to make sure that your outdoor unit is at least 2 feet away from any plants to prevent it from happening again. You may want to keep the outdoor unit hidden using the plants and shrubs but trust me, it will reduce the lifespan of your air conditioner and reduce the quality of air by introducing a lot of allergens in your home.

Clean the coils

To perform efficiently, the exterior evaporator coil must be cleaned regularly. You can purchase a coil cleanser online. Or can use a homemade solution by taking some dishwashing soap and mixing it with distilled water to clean the evaporator coil.

Check the ducts

It is common to find drooping or ripped ductwork after prolonged use over the years. Check to see if your ductwork is not showing such traits. Have your ductwork fixed by a good AC contractor in Wilmington, DE, to boost the efficiency of your air conditioner?

Check the refrigerant level

Your system will be less efficient if you use too much or too little refrigerant. Make the necessary adjustments to the refrigerant levels of your air conditioner. Make sure the refrigerant lines are well insulated and in good shape. Replace it if it is missing or broken. If in confusion, contact an AC repair in Newark, DE.

Check the wiring

After a long time of inactivity, the electrical wires may have loosened or, even worse, disconnected. You want to look out for such faulty connections before you can turn on your HVAC system. It is surprising how much harm can be caused by such a small-looking wiring fault.

HVAC maintenance can be a tiresome task. You can simply give a call to an air conditioner repair in Wilmington, DE, like D&T Heating and Cooling at (302)-838-6905 for a quick maintenance check.

  • Which Areas of Your Home Feel Comfortable When the HVAC Unit is On?

A good HVAC contractor will always ask you whether you want to improve comfort in certain parts of your living space. As a matter of fact, it is a critical piece of information that will ultimately help your contractor design a customized solution as per your cooling needs. In addition to this, your HVAC contractor can also suggest cooling solutions for different rooms. 

  • For How Long Do You Stay At Home?

The number of hours when you stay at home with your HVAC system on is an essential piece of information and you must share it with your HVAC contractor. If you intend to stay at home for a long time, then a high-efficiency HVAC system will best suit your cooling needs and operate more efficiently than a normal one. 

  • What Technology Would You Prefer in Your HVAC System?

It is a well-known fact that technology advances with time and therefore, it is always recommended to choose from all the latest options available in order to get the best value for investment.

Are You Dealing with Faulty Contactor?

A contactor is an electrical device that you can use to switch an electrical circuit on and off. Contactors have three components- the contacts, electromagnet, and enclosure. A circuit usually controls them with a lower power output than the switched circuit.

Contactors are an integral part of air conditioners. If your contactor goes terrible, your air conditioner won’t cool properly, and you may end up having hot and cold spots throughout your home.

How to Tell if You Have a Bad AC Contactor?

Air conditioners with faulty contactors cannot go through cycles (short-cycling) to maintain a comfortable indoor temperature. Here are some common bad AC contactor symptoms.

➢ Your system does not turn on at all.

➢ You hear a buzzing noise whenever you turn on your system.

➢ Your system makes a loud, clicking noise.

➢ Your system turns on but does not turn off quickly.

If you notice one or more of these signs, reach out to an experienced AC contractor in Wilmington, DEas soon as possible.

Testing an AC Contactor 

If your system makes a humming or chattering noise, test your contractor to see if it is the source of the problem. Follow these steps to test your contactor.

➢   Turn off the power to your AC: Your safety comes first. To prevent electrical hazards, shut down your unit at the thermostat and breaker level.

➢   Remove the side cover: Remove the side cover of the condenser. You will see multiple-colored wires connected to a black rectangle positioned vertically. That is your AC’s contactor.

➢   Take pictures: Take pictures of the contactor and corresponding wires from different angles, so you will know how to reconnect them.

➢   Remove the contactor and wires: Unscrew the contactor. Once you have removed the contactor, proceed to remove the wires.

➢   Test the contractor: To test your AC contactor, first set your multimeter to the OL setting and then connect it to the low volt terminals. If the reading is between 5 and 20 volts, your contactor is working correctly. If you get a lower reading or no reading at all, your contactor is faulty and needs a replacement.

Why Should You Not Try to Replace a Faulty AC Contactor Yourself? 

If you try to replace a faulty AC contactor yourself, you could end up injuring yourself or void the warranty. If you commit a mistake, things may get from bad to worse, and you could end up spending a ton on expensive repairs.

Frayed wires or a tripped circuit could cause your contactor to fail. Your air conditioning repair expert will get to the root cause of the problem and eliminate it.
