"Can't really find the words to express my full satisfaction with Kalthoff Handyman Services. I hired them to rebuild a very difficult deck---hillside/rock. They worked very hard to build a beautiful deck---quite an accomplishment. They worked thru late fall with very cold temperatures---never with a complaint. The price was fair and they never found reasons to raise the price. I was so pleased I asked them to do other jobs---new kitchen, 1.5 bathrooms (one was down to the studs), flooring in 2 bedrooms, front steps, insulation. Prices remained fair throughout. Always done professionally and with attention to detail/finishes. Tile work is beautiful/first rate. In the winter, the water froze (pipe in ground). They fixed it (found a way to solve the problem)---no charge. Really quite superior and I am fully satisfied with their work. Cory has the highest standards and completes whatever he says. I recommend them most highly and feel very fortunate to have found them."

At Flo-Pro, our mission is to provide expert plumbing and hvac services to our community. We are dedicated to ensuring customer satisfaction through quality workmanship and reliable service. We also offer free estimates and 24 hour emergency service!

"Chris was originally hired from Angie?s List because he met the criteria to advertise through Angie?s brand. We were going to have him install a forced heat unit in the house, top and bottom floors. He first encouraged us, then later, urged us to utilize our boiler system and replace baseboard heaters . it was feasible and his price was very reasonable. After hiring him and initially giving him $3500 down cash money, he began tearing holes in the ceiling to get the baseboard heater waterlines that burst. He cut twice as many as needed in the basement . He broke two 12 x 24 pieces of porcelain that we just installed. All of the baseboard heaters he has worked on have failed. The boiler he has worked on has failed. The work is all still incomplete and he?s putting our job off now-leaving us with no heat! He will not allow us a copy of his liability insurance for the damage caused. He has not offered to repair or replace the damage and will not give us a receipt."

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

Most AC units last between 10 and 20 years, but lifespans depend on the type of air conditioner. For example, central AC units last for 12 to 17 years with proper maintenance and regular inspections from a professional. Window AC units, on the other hand, last between eight and 10 years.
