Common AC Problems

As a homeowner, understanding common AC issues is vital for maintaining indoor comfort. F.J. Murphy & Son, Inc. recognizes these challenges and highlights six key AC problems to be aware of. Reduced cooling capacity, hissing sounds, or ice buildup on the evaporator coils can indicate refrigerant leaks. Inadequate airflow is often noticeable by weak or inconsistent airflow from vents and may be caused by clogged filters or duct issues. Thermostat problems can occur when your home is too warm or cold despite thermostat settings, indicating a malfunctioning thermostat. If your AC doesn’t start, there may be electrical issues, a faulty capacitor, or a compressor problem. Strange noises like banging, clanking, or squealing often point to problems with the fan, motor, or other components, and water leaks around your air conditioner or inside your home can be a sign of a clogged drain line or condensate pump malfunction. Recognizing these early is crucial for preventing more significant problems and costly repairs. Regardless of the brand or size of your AC, F.J. Murphy & Son, Inc. specializes in resolving these issues.

Our professional repair services ensure your system runs at its best, delivering the cooling comfort you deserve. If you encounter any of these issues, contact our team for reliable and expert AC repairs.

DIY vs. Professional Repair

When it comes to AC repairs, the choice between DIY and professional service is a critical decision for homeowners. While some may be tempted to tackle AC issues themselves, it’s essential to weigh the pros and cons. DIY repairs can seem cost-effective, but without the proper tools and experience, they often result in more harm than good. Inexperienced attempts can lead to misdiagnosed problems, causing further damage and potentially voiding warranties. Moreover, there’s a safety aspect to consider, as working with electrical components and refrigerants can be hazardous without the right knowledge.

On the other hand, opting for professional repairs, like those offered by F.J. Murphy & Son, Inc., brings a wealth of benefits. Our experts are trained to handle AC issues of any brand, size, or model, ensuring the problem is accurately identified and efficiently resolved. We possess the necessary tools and experience to prevent further damage and ensure your unit functions optimally. Safety is a top priority, and professional repairs guarantee a secure and compliant outcome. When you need indoor cooling, it’s better to be safe than sorry.

When should I purchase a new heating or air conditioning system?

At F. J. Murphy & Son, Inc., we realize that purchasing a heating or air conditioning system is no small matter. However, if your existing system is old, in need of continual repair or simply inefficient, purchasing a new unit, one which can be as much as 60% more efficient than a system purchased just 10 years ago, can offer long-term benefits. Rather than continuing to pay for costly repairs and costly monthly bills, you can invest in a new system today that will help save you money for years to come.

How can I find the system that’s right for me?

There are many heating and air conditioning systems to choose from today. We draw on our vast degree of heating and air conditioning knowledge and experience to help you decide on the system that best fits your specific needs. The size and age of your property, as well as the number of rooms, climate, local and regional utility costs, and utility incentive/rebate programs are all factors that will affect the functionality and, therefore, selection of your system. Utilizing the latest technology, we consider all these factors while assisting you in choosing the best system.

Consumers seeking to replace an existing system often choose a new unit with equal or higher efficiency ratings compared to their previous system. Replacing a unit that is 10 to 15 years old may reduce natural gas or electricity costs by 30 to 50%.

How do I determine the size, or capacity, of my HVAC system?

Factors affecting the size of your new system include our regional climate, inside and outside humidity levels, the number of windows and doors in your structure, total square footage inside, the geographic direction your property faces, the number of heat-producing appliances, the type of insulation you have, and the number of people that typically occupy the premises.

We can perform the proper calculations to determine the appropriate heating or cooling unit for your home or business.

I have a new air conditioning system but it's still too hot upstairs. Is this normal? Is there anything we can do about it?

This is a common problem usually found in two story buildings that were built without zone controls (separate thermostats for upstairs and downstairs). The best way to solve the problem is to adapt a new zone control system; it brings the temperature closer to being even.  Short of doing that, one thing that you can do to help but not solve the problem is to run the blower continuously. This helps to mix the upstairs air and downstairs air.

However, the electrical usage of the blower is a factor and can run as high as $50 or more per month if you let it run 24 hours per day. It’s best to run it only during severe problem times. Closing down all of the downstairs registers in order to force more cool air upstairs is usually not advisable since such an airflow restriction may cause icing of the evaporator coil, which will create a non-cooling situation.
