"We use Laury for repair and maintenance of our heating and cooling units for our rental properties and each time we need something done, the staff at Laury never cease to provide quality service. The technicians are always knowledgeable, thorough, courteous and pleasant. We recently had an HVAC system installed in one of our units and the home is rather large and is over 100 years old and there was not a whole lot of empty space to work with. The guys at Laury were able to install the system and all of the duct work and components involved neatly with the age and make-up of the home in-mind. They were pleasant throughout the entire installation which took almost a week. They were always on time and always communicated the process with us. Laury is a trusted business with many years of experience behind them. Prices are also extremely reasonable given the cost of services right now. Warren you are the man!"

"We called Clays and they had someone out and the unit repaired (it required a replacement capacitor and a contactor) within 3 hours - on MEMORIAL DAY WEEKEND in a shore town! Granted, we do have an annual maintenance contract for our HVAC system with them, but still, that's outstanding service."

"For over 20 years my wife and I used another A rated Angie’s List heating and air conditioning firm and we have given them good reviews in the past. Recently our 20+ year old heater started acting up. At times throughout the day or night the burner wouldn’t ignite and we would be without heat. After seven service calls and various parts at the cost of $700.00 our old service company could not repair the heater and the problem remained unresolved. So we decided to get estimates to replace our entire HVAC system mainly due to it’s age and this unsolved problem. Vaughan Heating and Air Conditioning was on our list of acceptable companies to speak with due to their Angie’s List A rating. We called Vaughan and they sent Tony Pellegrino to our home the next day. My wife and I were very impressed with Tony. He spent over an hour at our home scoping out our basement, configuring our new system and answering our questions. Later that day we received the Vaughan estimate that Tony sent by email. I called Tony and he spent another hour on the phone addressing my questions and concerns. We received the other competitor's estimates over the next two days. We accepted the Vaughan’s estimate which was $1,100.00 more then the lowest estimate and $2,500.00 less then the highest estimate we received. Our choice was based on our comfort level with Tony, the price of the job, the longevity of the company (established in 1937) and the quality of the heating and air conditioning units that Vaughan installs. We accepted the Vaughan estimate on Saturday evening and Tony scheduled our job that coming week on Tuesday (for the heater) and Thursday (for the air conditioner). The reason for the one day in between work was because they squeezed our job into an already full week of installations and we were really pleased that they did that for us. On Tuesday morning at 8:30am the installer’s, Marcus and Jeff were at our house ready to start the job. These guys were friendly, professional, extremely competent and also very neat and clean, covering our rugs, etc. Jeff and Marcus did and exceptional job installing our new HVAC system. It’s “state of the art”! My wife and I are extremely happy with the job Vaughan Heating & Air Conditioning did and we could not be more comfortable, then we are now, in our home. A great price, a great people and a great job! We highly recommend Vaughan Heating & Air Conditioning! Len & Lorraine Fedullo"

"They were great.  They gave me a verbal and written report at the end of the check up.  The technician explained how the heating system works.  He told me everything checked out well and that there was a lot of life left in my air conditioner and heat exchanger.  He did not try to sell me additional services.  I would use them again in a heartbeat if something did come up though.

"Both Brian and Brian arrived at my home on time. They started with the air duct cleaning, and since my house has centralized heating and air conditioning, they started with the HVAC unit. In addition to their punctuality, I was impressed by the quality and speed of their work. For instance, even though the estimated time frame for the work was 5 hours, the actual length to do this work turned out to be less than 3 hours. In addition, they were very knowledgeable, thorough, helpful, and professional. I would highly consider hiring them for this type of work again."

"Ed & Cris arrived exactly at 1PM when they said. They hauled in a heavy suction vacuum and attached to both supply and then return lines. Showed me the dirt collected in the first stage of the cleaner. Both men worked hard and did an excellent job. Was not ready for the dust throughout the house but they did warn me of it. We just finished a dirty tile job so the vent cleaning was a natural first. This is my second Angie's list contractor and we are contented.

Heating and Air Conditioning questions, answered by experts

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 $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
