With over 10 years of experience, we work hard to bring each customer the best possible service and quality available. We look forward to working with you on your next project. We welcome your questions and thank you for your interest in Kalthoff Handyman Services.

"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."

Heating and Air Conditioning questions, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

No. With a ventless portable AC system, you don’t need to vent anything out the window—but it will be harder to circulate the hot air from the room without one, so you’ll need to come up with another solution, like placing a fan near a warm spot and facing it towards and open water to push the hot air out.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

Some states require special licenses for HVAC professionals, but most don’t. However, even if there is no state requirement for HVAC licensing, local requirements might exist. It’s always a good idea to check if HVAC technicians need to be licensed in your area and then Angi’s contractor license lookup tool to confirm that the contractor you’re hiring holds the necessary licenses. Additionally, you should always ensure the company you’re hiring is fully insured to avoid potential lawsuits if a technician gets injured on your property.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.
