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.
