The technician arrived promptly at the scheduled time and approached their tasks with expertise and precision, ensuring that all problems were thoroughly addressed. The pricing for their professional services was reasonable. Overall, based on my experience with Dunn Service—characterized by politeness, professionalism, and fair pricing—I would highly recommend their services to anyone facing heating and air conditioning issues."

"I called Hosack on a Thursday morning because my water heater had died, and because of their great Angi reviews. They had a plumber, Kent, at my house before noon. Kent was fantastic ... great work, extremely knowledgeable, and VERY customer oriented. I'm extremely happy with Hosack's responsiveness, quality of work and attention to detail. Going forward, they (and I hope Kent!) are my plumbers of choice. I highly recommend!"

"Our house is 60 years old. We have lived her 42 years, this the first time we have had the ducts cleaned. The air in the house just seems lighter, the biggest thing is we have a black glass top entertainment center in the den. U could clean and 2 days later it was dirty again. We had this done2 weeks ago, it just now needs cleaning. We are very happy with the results. Would highly recomd it. Also vent centers is a filter company with wonderful filters for your air ducts. Ventcenters.com we put them in all our registers"

"I used this company to clean heating/ac ducts. They were prompt and responsive and the technician was professional and communicative. The only frustrating part was the difference in phone estimate and in home estimate and the number of "additional charge" recommendations."

Air Conditioning questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
