"They were prompt and very professional. They kept us informed during the entire process of cleaning our ducts and dryer vent. They also installed an air scrubber and the total cost was several hundred dollars less than the quote we received from an HVAC company. The HVAC company told us we needed mold remediationâ ¦. DuctGurus found no mold. We received great service so we will be using and recommending this company in the future."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"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"

"The technician Adam couldn't have been more professional and helpful. He arrived on time and was very courteous. He quickly was able to assess the problem and repair it. I'd recommend One Hour Heating and Air Conditioning to anyone looking to install or repair their HVAC system."

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

Customers say: Quality work

"I appreciate it when a contractor comes in and doesn't recommend a total replacement of the item. This contractor gave me options to think about. He repaired my water heater, even though it is old and does need to be replaced. He left me with the option that when I want to replace it, he gave me his cost and card. I will definitely call him when I can get my funds together."

"Stahls Mechanical is a top notch company and I would highly recommend them for any HVAC/plumbing work you have. My a/c went out and they were out within a day and had me up and running again in no time and at a reasonable price. Staff was friendly and knowledgable. Thank you Stahl’s and team for all of your help! Will definitely use you again in the future!!"

Heating and Air Conditioning FAQs, answered by experts

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
