I was amazed that Holt was able to install a new disposal on a Sunday. I thought I was going to have to spend my Monday morning getting it taken care of.

James just completed our furnace check. On time, neat, and efficient. For this not mechanically-inclined person, he succinctly explained why humidifier is not as efficient as should be. Suggested work around. Holt has done other work with which we were completely satisfied.

Nick came yesterday on an emergency call to fix my refrigerator water line so my new refrigerator could be delivered and connected. When they came to deliver the new refrigerator there was no connector for the new line. Holt got someone over within an hour and a half to fix the situation. They always do a great job snd are very professional and make sure things are done right!Dave installed 3 new toilets for us today and was very helpful in resolving some unexpected issues that arose. Everything was completed perfectly and in s good amount of time. Matt was also here to help him and they both did a great job and left with everything in good order!We have used Holt for plumbing and heating a/c for several years and have always been very pleased with the products and the service. Their staff are always efficient, knowledgeable and respectful of our home. Thank you! Tyler was here today and did a great job servicing our furnace and humidifier. Always a great job by Holt!Brad provided our service today and was very thorough cleaning both the furnace and humidifier. He was very professional and efficient. Always a great job by Holt employees!Zack came today to try to figure out what our hot water dispenser is not working. This has been a problem since it was installed and although I’m not happy with no resolution, Zack has worked very hard over multiple visits to try and figure it out!

Holt heating and air conditioning installed our heating and air conditioning system and now we have the maintenance program with them. All the different people we'd have had out to do the semi annual maintenance have been courteous and professional in there attire and speaking to us. I would use them for other services in a heartbeat.

I have Holt on the yearly plan. They check out HVAC ~ October and April. Yesterday I had my AC fail with temps expected to reach into high 90's all week. Nick Malloy had us up and running with cool air by 4:00. Very professional, friendly, and patient. A fine young man. Prior experience with Travis was same. Also had Mark do some remodeling and deck work. All are outstanding and represent themselves and Holt very well.*****/ ***** recommendationI had Holt Plumbing and Adam service also and rec'd same professional service, with a smile.Dan swoyer MD

* I haven’t yet made up my mind about which vendor we’ll use.Rob was very professional, courteous, patient, & pwell-informed: knew his stuff.Food for thought: One item where Rob seemed uncomfortable/hesitant was in response to one particular question: from which other HVAC companies he or Holt recommended I compare pricing. I definitely understand his hesitation (He said he had never heard that question before). From my standpoint it would be mutually beneficial for Holt to have this information at the ready in the event the customer asks for other bids from other reputable Central Iowa HVAC dealers/service providers: if the other shops’ bids come in much lower than Holt, I’d (from my standpoint at least) be wary of the lowball shop—hard to form trust in this instance. On the other hand, if the other bids come in higher than Holt’s, my (again just me here) inference would be that Holt is the better value: not only is the pricing most competitive, but I’d know that Holt is a top echelon HVAC provider and I’d be getting great service, expertise, and longevity.

Nick came out on a really COLD day to check out a concern that I had for the furnace. Everything is fine! (Glad to say that!) He is articulate, smart, and explained everything. The furnace does NOT have a problem. Additionally, he explained how to regulate the humidity in my condo as a ratio of outside temperature to condo interior temperature. I learned how to affect a liveable condo environment during the winter and avoid interior moisture build up on oversized windows. (WOW! I really appreciated the information.) . Holt technicians are well educated!!!

Guy came out to repair the water heater claimed that I needed either 1100 for a gas valve replacement that probably wouldn't work or 3100 for a new water heater. my brother talked me through it on the phone and for a $12 thermal coupler I fixed it myself. they made $100.58 just to come tell me lies and be.

My friend had her AC serviced last week and the guy was there almost three hours and did nothing. Didn't change the filter(the invoice said he did), didn't check capacitors, didn't check refrigerant levels and told her the thermostat was bad. She finally had to ask him to leave so she could get back to work. She asked me to look at it because it wasn't working. The service person turned the switch off on the furnace. Not sure why it took 3 hours to do nothing.

I've personally been helped by Josh, James & Tyler and they're all same - friendly, knowledgeable, fair and helpful. And James really knows his stuff when it comes to geothermal HVAC systems. I heartily recommend Holt H & P to anyone looking. Thanx Guys. Sam

Looking for a no fluff, no BS review of Holt? I got you... Over the past 15 years I've been a home owner, We've tried more companies that I could count. Lots of shady businesses out there... We were coming of a brand new HVAC installation just two years ago and the previous company completely botched it. It had problems within a month of installation and they were completely MIA. We ran it as long as we could to try and recoup the some cost, but it was a constant worry. Decided to give Holt a chance and we're so glad we did! Yes, they were more expensive, but it's the classic "you get what you pay for". 100% worth it! It's so hard to find a company that has the perfect mix of quality, punctuality, and honesty and Holt nails it. I genuinely appreciate their level of service and will pay a bit more to have someone I have the utmost confidence in doing the right thing. You should definitely give them a look if you need heating, cooling, or plumbing work.

Part 1 - (Approx. Nov. 2019) I spoke to Kelly on Saturday afternoon and she arranged to have Ben come look at my furnace the next morning. Ben was very helpful and he was a wealth of information. Very good service and no extra charge for coming on a Sunday morningPart 2 - (05/15/2021) Garrett came to our home to do a routine A/C check. As soon as he followed me into the furnace room he smelled gas which I was not able to smell. After he found it, he had me put my nose close to the union in the gas pipe and sure enough, I could smell it. He replaced the union on the gas pipe and now its as good as new! Garrett REALLY saved us a lot of trouble by being alert to the smell of gas!!
