We are the #1 Geothermal Heating and Cooling Experts in South Jersey, Central Jersey, and Southeastern Pennsylvania.  The U.S. EPA calls geothermal "the most energy efficient, environmentally clean and cost-effective space conditioning system available".  Upgrade to geothermal, and never buy heating oil or natural gas again. Don't just take our word for it when it comes to D&L's geothermal expertise. Here's what one of our recent customers had to say: “D&L has been an absolute life saver. We had the hardest time finding a tech who knew anything about geothermal systems, until we called D&L... A real standup, old school, quality service company. D&L got a new long-term customer in me, and I strongly recommend them.”

"He has done a good job."

Established in 2025, Gary Air HVAC proudly serves Delaware, New Jersey, and Pennsylvania with reliable residential heating and cooling solutions. Our founding team brings 10+ years of combined experience and a proven track record of 1,000+ successful installs and service calls completed. We specialize in residential HVAC installation, repair, and maintenance, delivering quality workmanship and energy-efficient systems tailored to each home. Whether it’s a new installation, ductwork fabrication, or emergency service, Gary Air is committed to comfort, efficiency, and professionalism on every job. Call us today you'll be pleased you did. Thank you

"I hired this crew to replace some old ductwork & add a couple vents. Wish I did it sooner. The estimator actually listened to what was going on, crawled the attic/basement, took pics, and explained what was leaking vs. undersized. The quote was clear, not the cheapest, not the highest, & they stuck to it. No weird upsells. Install day, they showed up on time, laid down drop cloths, and got right to it. They swapped a few crushed flex runs for rigid metal, sealed every joint with mastic (not just tape), insulated the attic runs, and added a proper return. They also put in balancing dampers so each room could be tweaked. Little touches too: they fixed a wobbly register I forgot to mention and cleaned up as they went. Place looked better when they left. The difference is real. Airflow is stronger but quieter, rooms are finally the same temp, and the system isn?t working as hard. Even the dust in the house seems better. They walked me through everything!"

"Jeff and his team did and excellent job with the installation of two Daikin HVAC units. I had many questions about the units and install and they were quick and thorough in responding. The price and warranty were competitive with high end brands. The crew was courteous and professional during the two day install. They were the only company that included replacement of the coolant lines, rather than just flushing the old ones. So far the Daikin variable speed AC units are exceptionally quiet and the house is very comfortable. Would recommend Ace Home Services and Unique Comfort without reservation."

"Travis checked the inside of my air conditioner for me and explained all the details of what needed to be done. He was very thorough. After what he explained to me what I had to spend on fixing certain wires, etc. in it, it would be about the same price as a new air conditioner. I chose a new air conditioner.Travis was the best! He listened and explained everything that needed to be done. He also listened to my needs. Thank you Travis, great job!"

Christian Heating, Cooling, & Plumbing has been a leading service provider in the Bucks County and surrounding areas since 1989. We've served thousands of customers providing each customer with expert technicians, honest pricing, prompt and friendly service, and personalized advice & recommendations on your heating & cooling or plumbing systems tailored to your requirements. We pride ourselves on our high-level of personalized customer service to ensure that your home environment is as safe and comfortable as possible. We offer service and installation of HVAC systems from Carrier & Daikin. Our expert service technicians receive ongoing training weekly to ensure they are able to fix any issue our homeowners may encounter.

"4/29/23 Christian tech checks our our home AC. He notes the cooling coils are rusty, a source of coolant leak, and the system, at 14 years age, is near it's end of life. He also noted some mold in the blower blades, which isn't easily seen. He put pressure gauges on the system at outside valves and reported coolant pressure was good. System was test run successfully. He sold us a 1 year maintenance agreement. 6/2/23 outside temp reaches 93 deg. We turned on the AC and only warm air came out. Outside compressor WOULD NOT RUN. We had Christian rep come out. He said all coolant had leaked out. He offered a leak test with dye for $510, or replace the "rusted" coil for at least $3681. We declined. A Christian salesman later quoted a full system replacement. We had another AC company investigate. He found the outside valves HAND TIGHT ONLY, which would allow coolant leak. We had him pressure test with nitrogen over a 4 day weekend, which he charged ONLY a $149 service call. Starting psi over 300. Psi after 4 days over 300 psi. We had him recharge the system. He noted that coils are rusty within 6 months from new. We then had him recharge the system. Total costs with labor & visits both companies $1,595. 7/11/23 Date writing this review. AC working well, same electric power usage for air temps as prior years. Christian seems more interested in selling new systems. Giving benefit of doubt, their 4/29 "technician" was incompetent."

Contact us today, we look forward to servicing you soon!

"I had an extremely frustrating experience with East Coast Comfort regarding a split AC/heat system. I first contacted them in July when the AC was not working properly. In October, after speaking with my HOA, I was told the unit was under warranty, which East Coast Comfort confirmed. Technicians came out, but the system only worked briefly before failing again. During the visit, one technician seemed unfamiliar with basic operation of the unit, and another stepped on my bed with dirty shoes, which I found unprofessional. In November, I was told there was a leak and a faulty sensor, but the issue was not fully resolved. Now, its a Christmas, and I am cold in my apartment, and East Coast wants more money for their visit, for something that they never fixed."
