"David was great to work with for an AC/furnace installation. He was very reasonable, transparent and responsive from day one. Under-promised and over delivered from a timing standpoint with our project and it was not easy. Highly recommended if you want good, honest service and no gimmicks."

"I actually had 2 systems installed. The main HVAC system for the 1st floor and a 3 zone ductless system upstairs. They were done in one day, very professional and cleaned up afterward. They were more than competitive in price and it was a pleasure doing business with them. J G., Phillipsburg NJ"

"The technician was very professional and was able to answer many of my questions about the condition of my HVAC system that I inherited and its probable lifetime. I sensed that he was being honest and straightforward. Rather than accept his extensive list of possible replacement parts, I opted to have him install the one that he believed to be the most urgent- the capacitor. So far the unit seems to be functioning well."

Heating and Air Conditioning questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

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.
