"Furnace was not operating because the company's automatic delivery system ran me out of oil.
Technician showed up promptly and got the furnace operating but could not get heat into the house. Had to reschedule to have zone valves replaced. Technician show up late and didn't have the required parts. Had to reschedule again.
The third technician showed up on time with all the correct parts and worked most of the day to get the system operating properly.
He was completely knowledgeable and very conciencious that everything was working correctly.

"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."

"Within an hour of purchasing the advertised special, Henry from B A R called us to set up an appointment for service. He seemed knowledgeable and showed up promptly to our appointed time. After working on the unit for about an hour he determined that the unit had died and there was no hope reviving it - it was 14 years old after all. WIthin a few days Henry was back and installed our new unit. Around the time he installed our unit, our second unit died. We had him replace it as well. The work was done in a timely manner and we have been completely satisfied. We would definitely hire B A R Appliances again for our HVAC needs."

"I did not have the work done. I rated C because the staffer seemed to know what he was talking about. When quoted a higher price, around $400.00, versus what I had planned, I deferred. The higher price included a "deep cleaning" extending beyond the ducts. I felt unprepared and pressured."

"Serviceman was prompt, courteous, and told me basically about what he would do to service the furnace before he started work. Reported that it was in good condition, needed only to replace the filter, which he did."

"It cost me nothing. Because I purchased the service contract with UGI, when I did need service work done it cost me zero. It's been a very positive experience so far. The timeliness is good. When I called them, they came the same day. They got a repair part and brought it back the next day. My furnace was not down very much at all. Very quick service. Very professional. Just a very good overall positive experience. I can't say anything negative at all. I would absolutely use them again."

FAQs for ducts & vents installation and replacement projects in Harrisburg, PA

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
