Summers in Newtown, PA can be unbearably hot, and an air conditioner running without cooling is the last thing you want. Have you noticed your air conditioner blowing warm air or taking forever to reach the set temperature? It may be time to stop and assess what’s going on. Knowing the most common problems and remedies will allow you to save money and stay comfortable. Realizing when it is a small fix and knowing when to call in the professionals is an essential piece of the puzzle.

For Newtown homeowners, prompt and reliable air conditioning services in Newtown PA will ensure your system stands up to the heat of summer. Let’s look at some common reasons your system isn’t cool.

Common Causes of AC Not Cooling Properly

  • Dirty or Clogged Air Filters

One of the simplest yet most overlooked reasons your AC would better be cooling is a dirty set of air-filters. Over time, these accumulate dust, pollen, and other debris, causing poor airflow and forcing your system to work harder. This reduces cooling efficiency and also risks harm to its internal parts.

Quick Fix: Clean or replace your air filter every 1 to 3 months. In case the problem does persist, professional Air Conditioning Services in Newtown PA can come to inspect and aid you in installing high efficiency air filters.

  • Refrigerant Issues

The refrigerant is the blood in your AC system. Low levels or leaks cause your AC to blow warm air or maintain the desired temperature. No refrigerant usually signals to possible leaks that require an expert’s solution.

Quick Fix: If refrigerant troubles are suspected, please do not fix them yourself. Certified Air Conditioning Services in Newtown PA will recharge the system and fix leaks for full operation.

  • Thermostat Problems

Sometimes, the actual trouble lies not with your AC unit but with the thermostat. Bad setting, dead batteries, or a faulty thermostat can hinder the system’s operations. In some instances, it works but doesn’t perform the required cooling when needed by the system.

Quick Fix: Set your thermostat properly and change batteries if needed. Call on Air Conditioning Services in Newtown PA to test or replace the thermostat should the problem persist.

  • Dirty coils

Both evaporator and condenser coils are heat exchangers. The dirt accumulated on these coils can affect the cooling process and could further lead to increased electricity costs. In many cases, dirty coils are a trademark of aging air conditioners or homes not attended with proper maintenance.

Quick Fix: Cleaning coils requires opening the unit and delicate handling. Professionals offering Air Conditioning Services in Newtown PA can clean coils safely and efficiently.

  • Blocked Air Vents or Ducts

When a vent is blocked or closed, there will be less air coming out of the vent; hence the cooling will be uneven. Furniture, curtains, or even pests can obstruct your vents and ducts and hamper your AC’s efficiency. Damaged ductwork may also contribute to air leaks in some cases.

Quick Fix: Make sure all vents are open and not obstructed. For complicated duct issues, contact Air Conditioning Services in Newtown PA for inspection and repairs.

  • Freezing of Coil

The formation of ice on the evaporator coils is yet one more reason the cooling performance is compromised. This formation occurs usually due to a condition of having less refrigerant, restricted airflow, or dirty coils. With a frozen coil, the AC does not develop any cold air, and that puts one in discomfort.

Quick Fix: Give a shutdown to your system to allow time for the coils to dry. Check around for any airflow or refrigerant issues. Qualified technicians from Air Conditioning Services in Newtown PA will work to ensure it does not happen again.

  • Electrical Failures

Interrupted operations can be caused by bad capacitors, blown fuses, or worn-out wiring. An electrical issue can stop the compressor or fan from running, thus not providing your system with cooling, even though it appears to be working.

Quick Fix: Electrical problems require the attention of professionals. Licensed Air Conditioning Services in Newtown PA can diagnose and repair electrical defects with safety.

DIY Quick Fixes Available

While there are problems that only professionals can handle, a homeowner can address certain issues by implementing the following quick solutions:

  • Check and Replace Filters- it is advisable to always check air filters to avoid blockage problems.
  • Inspect Thermostat Settings – make sure that the system control is set to ‘cool’ and the temperature is lower than the present ambient temperature.
  • Unclog Vents and Coils – clean any dust or debris from vents and reachable coil areas.
  • Reset the Power – in most cases, the air conditioner may go back to working by just switching the relevant breaker off and on.
  • Clear Any Blockages- there should be no such objects that restrain the air flow around the ducts or the external unit.

If these attempts don’t yield desired result, then it’s time to seek professional assistance. issues our emergency ac services fix instantly come in handy at such moments.

    Fantastic customer experience with GB Heating and Cooling, from the on-site quote to installing a new Lennox HVAC system (AC Condenser Unit, Furnace, Evaporator Coil, AprilAire Air Purifier, and Condensate Pump). The family-owned business provided a very fair quote, which provided a more efficient and mid-level unit compared to other HVAC companies at the same price (for only the AC Condenser Unit and Evaporator Coil), providing less efficient and base-level units. The installation team started their work in a timely manner and ended in a professional manner by cleaning up the work area. Installation started at 10:30 AM and ended around 7 PM, but the on-site lead wanted things to be done with perfection and intent regardless of how long it would take. For example, the previous HVAC system had level drain pipes from the HVAC/Humidifier, but during the re-pipe, it was sloped to prevent the backflow into the system. The small detail may not be known by the average consumer, but the lead did it anyway to prevent any future issues and doing it right the first time. It was a great experience with the company, and I hope others call them for any HVAC services!

    I had an emergency situation with my water heater past weekend and that is when I I called them. They were prompt and not only that they made my emergency situation their priority and. Regardless of the time factor and despite of the holiday weekend they came right over in short notice and got the job done professionally. They are extremely knowledgeable and I am very happy with their state of the art technology, services, courtesy, and professionalism. I would recommend them without a doubt.
