"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

"Our family had a terrible experience with His Workmanship. We hired 4 workers for 8 hours for two days (9-5 each day), to weed and mulch bedding in our yard, at a cost of $4420. On our first day, we did a walkthrough to show the weeds and beds. Before the second day of work, we shared pictures of large weeds the team missed on the first day (likely they weren’t identified as weeds), and agreed that we’d be back by 5:00 to walk through and settle with the team. Evidently our e-mailed instructions, photos, and the first day's verbal instructions were not relayed, because the second day's team only finished mulching the one incomplete area left by the first day’s team, leaving behind weeds, unmulched beds next to adjacent bags of mulch. The team tried to contact me at 3:00 (as I made clear, I was at work and not available), then left. My wife returned from work by 3:30 and the team had already left without authorization and without doing any of the weeding in our verbal correspondence, e-mailed correspondence, or e-mailed photos. They left all areas that the prior days team had not begun unweeded and unmulched, along with extra mulch in our driveway right next to the unweeded and unmulched beds that we had asked them to take care of. They charged us for the full eight hours after leaving two hours early, without authorization, and without the walkthrough we agreed to do when we returned from work. All our e-mailed correspondence and Ring screenshots with timestamps are available upon request. Given that our instructions were all in writing and we followed our commitments to be available after our own workdays, we asked to be credited or refunded for the two hours they left without authorization and undone work (communicated both verbally and in writing). His Workmanship confirmed that the team was not supposed to leave without authorization, but declined to credit or refund the time they were paid to work but not working or available to work. I don’t fault workers, who probably never received any direction from the team hired on the first day or my e-mailed instructions. We paid them fully while they were on the clock but gone from the property. We don't want the company's poor communication or loose norms to affect the workers. But I do fault the company for not delivering on what we agreed upon and paid for, failing to honor our written instructions, and then not making it right with us. Given their poor internal communication, inconsistent supervision, and unwillingness to correct their mistakes, I would not recommend them, especially if you need to be away while they are supposed to be on shift. I leave you with a photo of one of those piles of mulch, next to one of the many unweeded, unmulched areas of our yard, that the team left behind mid-shift, after having been instructed to apply it. The second photo is one that I had sent them of weeds to be removed, but they were not despite all the extra time they had before they all left. (I shared the substance of the above with my contact at His Workmanship to confirm the accuracy. I was offered "one free hour" if I bought two hours additional work. We do not want "one free hour." We want the work that we paid for, but could not receive, because the team left before we returned from work and during their shift.)"

FAQs for central a/c service or repair projects in Jefferson, WI
Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.
Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.
An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.
In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
