HL Bowman has been in the same location for 38 years and owned by the same family for over 65 years. HL Bowman is a non commission based company. HL Bowman employees will never upsell you a product you don't need. Dennis and Bryan Enders and his family have deep roots in the Harrisburg community. After 65 years Dennis and family stay committed to giving the community the best possible service and product to fit their needs. HL Bowman has won Angie's List super service award every year.

"Adding to the above review: NEGATIVE STARS 1. The Daikon' ductless mini-split' unit, sold to me by Brian Enders and installed by H.L. Bowman Incorporated, unleashed a deluge that not only saturated the hardwood floor in my dining room but also flowed onto bookshelves and drawers in the room below, drenching 25 family photo albums. 2. The water pooled atop and between each section of my quarter-sawn oak Stickley barrister bookcase. 3. The water seeped inside each section of the bookcase. 4. The water ran onto particularly important and expensive books, framed photographs, as well as four small wooden boxes containing four of my dog's cremains. 5. In past years, water from a second-floor unit emitted sufficient water to cause a 12' by 5' section of the upstairs floor to crash through to the main floor. All furniture and items in that 12' by 5' section were so water-damaged that they had to be discarded. Water ran behind the plaster and into the wiring contained within the plaster walls. I had to make an insurance claim to have that water damage repaired. 6. In past years, water from a basement unit emitted sufficient water to cause an entire wall of built-in cabinetry to be destroyed and have to be replaced. I had to make an insurance claim to have that water damage repaired. 7. In past years, four of the six "ductless mini-split" units have simply not worked. They do not cool. They do not heat. They hang on the wall and blink. 8. Throughout these years of destruction, distress, and financial duress caused by the six 'ductless mini-splits,' Brian Enders has consistently refused to rectify the problem. 9. The FIRST REASON Brian Enders uses to refuse to rectify the problem: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit, Brian Enders offered substandard assistance. He sent a contractor to my home to spackle over water-damaged plaster, thus sealing water inside the walls. When I saw the inferior repairs Enders offered, I stated that I was going to call my lawyer. Enders said that because I had threatened legal action, his company would no longer serve me. 10. The SECOND REASON Brian Enders gives for refusing to rectify the problems: When the ceiling caved in from the upstairs unit and the cabinetry was ruined by the downstairs unit and Brian Enders offered substandard assistance, I wrote bad reviews of Brian Enders and his company "all over the internet." (Enders words.) Yes. I did, indeed, write bad reviews of Brian Enders and his company, H. L. Bowman, Incorporated, "all over the internet" and will continue to do so until Brian Enders and his company, H. L. Bowman, Incorporated, make the six Daikon "mini-split" units they installed in my home work properly. 11. Because Brian Enders and his company, refuse to help me, I have paid five other companies, & one private contractor, to come to my home to diagnose and repair the six Daikon "ductless mini-split" units. Each one has been unable to do so. Each one says that there is something so faulty about these units &/or the installation of these units that it is impossible to determine what is actually wrong with them. 12. On Saturday, June 22, 2024, I tried to set up a service call with H.L Bowman, Incorporated, using a form on their website. 13. On Saturday, June 22, 2024, I received a text from H.L. Bowman confirming an appointment for Monday, June 24, 2024, with a note relating that on the day of the service, I would receive a call 30 minutes before the technician arrived. 14. On Monday, June 24, 2024, I instead received a phone call from H.L. Bowman informing me that they are too busy serving their VIP customers to send a technician out to serve me. Today is Tuesday, June 24, 2025. H.L. Bowman has still not rectified their financial and material injury to me."

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

While parts of the appraisal are out of your control, there are some things you can do to potentially raise the home’s value. You can make necessary repairs and upgrades before the appraiser visits—an appraiser can only value what is currently part of the home, not its potential. You can also provide the appraiser with the cost of recent upgrades. The appraiser will likely increase the value of your home by about 50% or more of what you paid for those improvements.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
