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.

If you are looking for a reliable HVAC contractor for air conditioner repair in Wilmington, DE, your search ends here. D&T Heating and Cooling 25-year experience in the industry and trained HVAC technicians are equipped to handle all your AC repair, maintenance, and replacement needs.

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.

Working of a geothermal heat pump

The working concept of geothermal heat pumps is simple. It’s an electrically powered unit, which is like a refrigerator that uses earth as a source for heat exchanging. The temperature inside the earth is 50 to 60 F always consistently. The pump just uses this heat of the earth to warm or cool the room air.
The GSHP unit contains a heat pump, ground loop containing water which circulates along the pipeline to extract ground heat, and a duct system that transfers the hot or cold air to the rooms.

Heat from the earth is picked up by the circulating water in ground loop. This heat is the extracted from the water by the pump. Then the hot air is sent to rooms through vents by the air ducts for winter room heating. In the summer, heat is extracted from room air and the loop water is heated using that extracted heat. While the room air gets cool the heated water dissipates the heat to the ground, or that heat is used for water heating in the home.

Benefits of using geothermal heat pumps

A geothermal heat pump system comes with the following benefits at a glance:

  • No fossil fuels are burnt in the use of this pump. Hence emission of carbon dioxide is null here. Also much less greenhouse gases are released.
  • Due to no emission of carbon monoxide the air quality is very rich with GSHP units.
  • Once installed it has roughly 20 years durability in general.
  • Efficiency of geothermal heat pumps is almost 400 percent compared to 78 to 90 percent efficiency of other fossil fuel powered heat exchange pumps.
  • This kind of pump can be operated using a smart home remote controlled system through computers.

Before you hire a contractor to repair your heating/cooling system, it’s best to first consider if it’s a good idea. Think about it, will you get a better return on your investment if you have it repaired or replaced? To help you make a decision, here are some things for you to consider;

Is It For You to Replace Your HVAC System?

It’s quite obvious that you need HVAC replacement in some situations. If your heating/cooling system is one or more of these predicaments, then it likely needs replacing. Better weigh the pros and cons of repair over replacement before you hire a contractor.

  • HVAC System is 10+ Years Old

There’s a simple rule to know if your HVAC system needs replacement. If it’s over 10 years old, then you need to start looking for a new one. Most heating/cooling systems only last at around 15 years. If not yet within 10 to 15 years range, there’s no immediate need to replace if it still functions well. However, you must keep in mind that an old system, you’re likely going to spend more on utility bills.

  • Safety Hazards

Safety should always come first. In that case, if your HVAC system is causing you safety hazards, then replacement is your best solution. There are some scary consequences with malfunctioning heating/cooling systems. Some of these include fire hazards and carbon monoxide poisoning, which you certainly don’t want to happen.

  • Constant Repairs

If you always need to have your HVAC system repaired, it’s probably the best to replace it instead. Otherwise, you will be spending more money when you could have just paid once for a functioning, high-efficient heating/cooling system. Here’s a tip: if you’ve paid more than $1000 already for repairs, it’s time for HVAC replacement.

HVAC Replacement Process

If you are thinking of HVAC replacement, here is some information that will help you before the project starts:

  • Get estimation for the HVAC replacement costs
  • Decide whether to replace only a part or the entire HVAC system
  • Calculate your HVAC’s correct size
  • Learn about basic terms/information about HVAC systems
  • Find a reputable contractor or replacement company

Before the replacement/installation system, you’re going to need to do some things to quicken the process. For one, move your valuables and important objects to somewhere safe. Contractors are usually uncomfortable about moving your expensive items.

If you have pets, move them somewhere safe as well. By doing, you can reduce the chances of anything unforeseen to happen. Your HVAC will be repaired quickly and you can reap its benefits quickly at the same time.
