We are committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"On a Saturday afternoon, I reached out to Tavoni Heating about replacing a hot water heater. I heard back quickly--and I was able to schedule installation of a replacement heater for the next day (a Sunday morning) at no extra charge. Mr. Tavoni took the time to explain the installation process in detail. His work was thorough and reasonably priced (I had estimates from other contractors). The unit is quality construction--and it comes with a six-year warranty. Tavoni has taken a water sample and he's agreed to help me explore the possibility of also installing a water-filtration system for my home."

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!"

When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"

FAQs for window a/c unit installation projects in Thornton, PA

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
