"Shawn was a professional from start to finish. He was transparent about his pricing, communicated clearly, and finished the work in a timely manner. My heat pumps efficiently heat and cool my house, and I recently contacted him to install another in my work office. I would highly recommend Shawn for all your heating, cooling, and maintenance needs."

My name is Jay Scannell and I enjoy cleaning and making things spotless. My mother always made sure our house was clean as I was growing up and naturally I have liked to follow those similar footsteps and take it that one step further. I’d enjoy cleaning for you and your family if need be and I am open to anything you throw at me:).

"Exceeded all expectations. Dennis and his helper were amazing. Kept us informed when special order parts would arrive. Absolutely one of the best experiences I have ever had with a contractor.. In a Five Star ranking system I would give Preferred Oil & Propane Service at least 7 Stars."

"They did an excellent job. They initially misquoted the price on the low side but the president said they would go ahead and honor that price. They were very responsive to anything needed before and after the job was done. They stand behind their work and in my opinion are an exceptional company. I would highly recommend them and I would definitely use them again."

Air Conditioning FAQs, answered by experts

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.
