Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"Rick, the initial assessor for the (HVAC, electrical and plumbing work), was superb! He efficiently inspected the areas and subdivided the work while giving useful feedback. I look forward to the help from Jones Services!"

We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"I was a little disappointed because I hired this company based on the reviews and the issue was not resolved the first time the pro came out and I had to pay twice for him to come back to adjust the same issue. I would have to say that maybe my pro was not as experienced in handling my heat issue but I would not dissuade others to not hire this company."

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."

Hello, my name is Mehmet. I can do many repair jobs in your home. If the circuit elements in the electronic devices are not burnt and the material I will change does not require more than 1 person's manpower, I can come and do it myself. I wish you a good day. 😊

Heating and Air Conditioning questions, answered by experts

To find a reputable HVAC company, start by finding providers in your area that have mostly positive reviews online. Next, check the Better Business Bureau’s website for customer complaints. Some states and municipalities require technicians to be licensed, so you should rule out companies that aren’t. Finally, contact each professional and ask for per-hour pricing, contract availability, and references to call. You can also ask if they have worked on your particular system brand in the past to confirm that they’re qualified.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.
