Recommended Customer Reviews

The is a picture of the ""new"" unit.
It was delivered damaged.
I spoke to the sales representative who sold me this unit.
He is doing nothing to help.
Basically he took my money and ran
Their customer service is horrible!!!
The company does false advertising as well.
They are not a one hour service company.
They come when they want

I am writing a letter now to this company to say how unhappy I am and how terrible the service is. I paid $10,500 for my unit which has had error messages from the very beginning. I have called numerous times and the problem has never been resolved. I have paid less than $4,000 for HVAC units from other companies and have never had a problem. When I called and speak to a person named Dion she is always getting smart with me on the phone. Stay away from this so-called company.

So, here's the deal. DO NOT JOIN THE ""CLUB""! I was sold a bill of goods on how joining the club put you on a priority and you wouldn't have to wait/same day service and all that. Well, it turned out to be a load of crap. They performed service on our units a couple of weeks ago. Not sure what was involved in the service because we turned on the heat for the first time with the cold snap last night and no heat. I called this morning (Tuesday) and was told they wouldn't be able to see us until Thursday afternoon! Doesn't matter that THEY just supposedly serviced the units and I'm a member of this so-called ""club."" Also, we experienced a similar delay of 2-3 days when we needed service on our AC.
UPDATE: So I found another company to come out today (they were even early) and I will review them elsewhere. The reason for this edit and downgrade to one star is that the service Duggan's did the first week of October was not done correctly. The coils in the main unit were completely filthy and gummed up. That is definitely supposed to be part of the routine maintenance and the technician could not believe how recently the unit was supposedly serviced. So, even with another six months left on my club membership, Duggan's will not see my house again. Thankfully, I hadn't gotten them signed up to service the business yet.

I contacted this company to get a new HVAC system. The only thing I could say positive about them is they have a really good salesperson. For subsequent needs, they lack customer service quite a bit. My system was installed the last week of December 2019. During installation there were 2 guys working and another dropped by without acknowledging my presence in my home. At the end of the installment, they seemed to rush out and I had to ask for instruction on how to program my new thermostat. That process was rushed as well. I followed up with the local company about my warranty and wasn't issued it until months into 2020, I think March. I had to call for a service check July 4. When I did I explained that I was in my 2nd trimester of pregnancy but due to the overhaul of calls, I wasn't able to get serviced until the next day. The technician that came did not wear a mask inside my house and told me because it made him hot. And he explained that upon my initial installation, they did not flush the line which caused the problem. I asked if this was covered under warranty and was told it was. Over the last 2 weeks I have began to have issues with my system not working around 4pm. I called about it and was told I had to leave a credit card number on file so they can charge me since I wasn't going to be at home during the service call. I told them I was not comfortable doing that and was met with what I believe is attitude from someone named Dion that I was speaking with. I wish I could give this system back to them and never looked their way. They have poor customer service and lag with follow up.

Warning: Stay FAR away from this company!
They sell extremely poor quality products that do not last. Further, they price gouge you when you call about a repair and/or maintenance. Finally, the technicians are not doing quality work.
We bought a brand new air conditioning unit through Duggan and in less than 24 months it was broken. From that point, their technician has been out to fix the unit every 6-12 months which has costed us thousands of dollars. This is not normal for brand new equipment which should last 10-20 years.
Further, the staff is unwilling to help resolve the issue but would rather continue charging us for repairs. We are thoroughly disappointed in their service and business practices.
They don't even deserve one star.

I highly recommend Duggan's One Hour Heating and Air. They installed units in my home and service them twice a year. The technician Calvin arrived on time to service the units this month. He cleaned the units and replaced parts under warranty that needed to be replaced. He explained everything he did to keep the units running well. He left the work areas neat and clean. He was extremely polite. I highly recommend Duggan's and especially Calvin for his A++ Service!

Let's start with the good: We chose Duggan as part of a buyer agreement to have our HVAC inspected following the sale of our home. The tech was on time. He checked out both furnaces and both AC's, found valid flaws and corrected them. Total cost was right at $500. After he left, I noticed the smell of natural gas upstairs. I refrained from calling the gas company for all the fuss and emergency vehicles they would send (I've been there), and decided to call Duggan instead, so long as they could get the tech back to the house immediately. He returned right away, and was already carrying a length of flex hose, admitting that he knew what he had done--he had failed to replace a piece of flex hose that got damaged during the work.
After he left, the downstairs AC began freezing up. It seemed suspicious, given that the tech had just left, and I called them again after the weekend. Almost all of the problems with freezing up are the fault of a low charge. The tech argued with me on the doorstep, insisting my capacitor needed replacing, because the evaporator fan did not work, which caused the unit to freeze up. I insisted that the evaporator fan WAS running, but he insisted that I was wrong. Eventually, I let him have his way; he installed a new capacitor, and charged me $250 on top of the $500 I had spent a couple of days prior. He refused to add freon to the unit, telling me that it was ""illegal,"" and said that, with the new capacitor, the unit would work. Except it didn't. It froze up immediately. Because... freon.
I called the home warranty people we normally deal with, and they sent out a tech, who agreed that the freon load was the problem. After a quick load of approximately 1.5 lbs of freon, the unit worked again.
I'm afraid Duggan punked me. Punked me real good.
I would have given them 3 stars, even with the gas leak. After feeling punked, I give them one.

Honest, hardworking, and high integrity company . Our diligence period was almost up on our home that had a 1992 A/C unit. We just moved to the area so we had no who to use to look at our 1992 unit. I reached out to them late Thursday hoping to get someone out there before the weekend. The sweet receptionist on the phone refused to tell me they couldn't come even though they were fully booked and told me she figure something out. The owner, Tony, ended up coming to check out our A/C unit and furnace Friday morning. Right off the bat when speaking with Tony my instincts told me he is honest and has integrity. They have set prices so you never have to wonder if they are over charging you. Reasonable and fair pricing. They do background checks & drug tests on all their workers. That last part is everything to me when allowing someone to enter our home.
*Tony noticed something at our house that was a huge safety concern (our house could have easily burnt down) that we had overlooked with all the chaos of buying our first home. Tony also let us know we need to take care of that other issue first before we worry about anything else- even before throwing money his way for a new unit.
Again, hardworking, honest and high integrity. Everything I want when doing business with someone.

Tech came out ($89) and told me I needed a new unit $6000 or $1500 worth of repairs. I had a second company come out and look at it, they fixed the control panel in 5 mins and cleaned the entire unit for $150. They either need new technicians or need to teach their techs to fix things instead of upsell.
