"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Woke to a chilly home stemming from a heat-pump issue. Posted my repair service need on Angi and within minutes, received a text and phone call from HOFFMAN MECHANICAL, who was able to come out same day and got my Lennox unit up and running again at a fair cost for both parts and the weekend/after hours service call fee. I would use them again without hesitation, and I am happy to highly recommend this company!"

"I would give MORE stars if I could. Service was excellent. Greg arrived at the appointment time, was clear about what he would do and how he would do it. He was very clean in his work. He removed all duct covers, then began the cleaning. I had some issues with the antibacterial disinfectant (allergies) he would be using. He advised I could research it and let him know. He even allowed me to smell the disinfectant. We did use it and the smell was very mild and dissipated in about a half hour. After cleaning the duct work, he returned all the duct cover and cleaned up his work area. He worked by himself and had the job done in under 3 hours. And the price was fantastic, coming in at over $150.00 and $300.00 less than 2 other bids. If you're looking for duct cleaning for your HVAC system or dryer (he did that, too!), The Duct Pros are where you want to go! Thank you Duct Pros!"

"Justin arrived on time, and asked me a few electrical related questions about my house before he statrted. I have interacted with many electricians and HVAC contractors in my profession as a field engineer, and I'm here to tell you Justin and Wentzel are the real deal. I plan on using them again when I do some other electrical stuff for my home in the future. Labor and material rates are very reasonable, and the quality of work is excellent."

Heating and Air Conditioning FAQs, answered by experts

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.
