    • We called late on a Friday night after our furnace stopped working. Mike Herran came out within an hour and got us up and running. We were incredibly impressed by his professionalism and the very reasonable price for calling them so late on a Friday. Will continue to use him for all of our HVAC needs!

    • We have used this company for a number of years and are never disappointed with their professionalism, promptness and work. Our entire family uses them for their own homes.
    • Our furnace surge protector melted and short circuited the furnace. Of course it broke on Sunday night. I called one hour heating and they came and fixed the furnace. I'm very grateful to Jeff our repairman who was able to fix the problem.
    • Jose analyzed the problem quickly and explained what needed to be done.

    • Gerald was patient and listened to my challenges with the heating. Turns out it was the perfect storm of several missteps, one he could fix, the others were things I needed to do to improve the heat flow. In the end, everything is working and my home is again toasty warm. Thanks Gerald!!

    • We had our furnace cleaned a couple of weeks ago which revealed a problem with the blower motor. The problem was explained and it was decided it should be replaced. They ordered the parts and got back to me quickly to do the repair. They always call the night before to remind and confirm the appointment and then call again to state the tech is on their way. Piyush came to perform the repair and updated me along the way and answered any questions I had when the work was complete. Everyone we have worked with, from the office staff to the technicians, is friendly, professional and patient. Will continue to call on this business for our HVAC needs.
    • Always professional and thorough. Never a complaint with their service. Gerald was no exception today.
    • Worker was friendly informative and wore all the proper protection.
    • We were so happy that Mike was able to get us up and running so quickly and for such a reasonable price. We will continue to request him when we call for service in the future. Can't tell you how great it is to get good service like this.

    • Mr. Brownstein was quite professional. I was impressed that he took the time to examine the particulars of my home, noting the air circulation, and exploring any concerns I had. Next, he did a thorough examination of the furnace and when completed, took the time to let me know the status of the equipment and offer some worthwhile alternatives I could consider. I am quite pleased with his work and consider him an excellent ambassador for One Hour. Thank you.

    • Excellent service from quote through installation. Great team, professional, and on time work was done as quoted, no surprises or add-on's .
    • Mike is amazing at what he does! He came in and admitted within minutes there'd be no way to do a full repair right there and then (we called after hours) but he'd try and get it running so we could get through the night. Dude worked his magic and the next we knew we had heating until we could get a full repair done. Amazing. 5 stars.
    • Mike was wonderful! Checked everything thoroughly, answered all of my questions and set up an appointment next day! Thank you for your knowledge and kindness Mike!

He performed the cleaning in a reasonable amount of time and explained clearly an issue with one of the parts and the cost of replacing or cleaning it. He was not pushy at all and gave me all of the information so that I could make an informed decision. I will continue to use One Hour Heating and Air Conditioning for service of my furnace and A/C.

Not only did he come out within an hour of our call, he took the time to troubleshoot and review everything with us so we could see what he did so we know what to do in the future.

      - Elizabeth B.
    • We are grateful for Josh and Lloyd's help with getting the new air conditioner installed. My 89 year old Mom was nervous about how the day was going to go, but they were professional, considerate, and got the job done. The retrofitting of the new coils looked pretty complicated to me, but Josh is clearly no stranger to this sort of work, and Lloyd was an excellent co-worker (I'm sad there isn't a separate entry for him, he was very polite and considerate as well, closed doors behind him when entering and exiting the house). All in all, both gentlemen were fantastic and such polite hard workers! I don't know how many more years I have with my Mom, but I'm thankful that she will be cool and worry free for the summers to come! We will continue to tell our friends about One Hour Heating and Air because of your great service and team, thank you again!
      - Nellie & Alicia O.

    • Jose was very professional and spent a good amount of time attempting to solve the problem with my air conditioner. This air conditioner has been a problem since the day it was installed so I will wait and see if there is any change by Saturday morning. Jose told me it can take several days to remove the humidity from the house but as of right now there has been no change at all (humidity is at 80%!).

      - Jack & Nadine
    • The installation of both a/c and heating went well. We are using the a/c now and it’s functioning as promised. We have to wait for cold weather before using the furnace so no feedback on that for now. Joshua was pleasant and professional. He did nice work.

    • As always Jose did his job perfectly. Using deduction skills worth of Sherlock, he starts his tests. And then says, "if it isn't this or this. And isn't that, then the only thing it could be is....." And he goes outside and finds the blown capacitor. It doesn't get any better than that.
      - Tim & Susan
    • James was great. He found my problem and had me up and running in no time. I hope I get him next time also.

    • I have used One Hour Heating & Air Conditioning for years. I also have a service contract with them. This is one well run company! Today I had my heating system serviced by Tariq, who was efficient and knowledgeable. He explained options that were available to address uneven heat distribution in my two story home. No pressure - just information. A+
    • I have used One Hour Heating & Air Conditioning of EGV for over 20 years. I am on my 2nd unit with them. Today I had routine maintenance performed by Marius!  He was very courteous, professional and on time.  He explained everything to me as he was completing his work. I have nothing but good to say for all the people I have dealt with at One Hour, especially Rose!  Excellent choice for your Heating & Air conditioning needs!!
    • What can I say? We are pleased once again with the service from One Hour Heating and Air Conditioning!  Rose was her usual prompt and friendly voice, checking in to see how we were doing as well as reminding us for the scheduled maintenance.  Raudell was a fantastic technician: polite, efficient, friendly, meticulous. He took time to let us know that the unit was working well, and asked us if we had any questions or concerns! We look forward to Rose's cheery phone call in the fall for the furnace check up and are grateful for skilled and caring professionals like Raudell to keep our home temperature comfortable--thanks again!!
    • 18 Years and now I have to say Goodbye to my furnace and AC. The people that service my AC and furnace are the greatest.  Mike Jones gave me a great deal on the new stuff and checked to make sure that everything was working OK.  Give them a call and they will take great care of your furnace and AC.  Tell them Kathy sent you!
    • Mike, the Comfort Concierge, is just about the nicest, most knowledgeable, and sincere person you'll ever meet!  He came over to assess the ac and furnace systems efficiency and effectiveness. He took measurements, inspected the units, and thoroughly explained not only my options, but also how various parts work and why they are important.  He was able to make calculations pertaining to the needs of the systems as well as to the cost of new units. He understood and was able to effectively communicate that although replacing unit(s) may be an investment, there are also many benefits to the investment.  He clearly loves what he does and is very good at!
    • Alger was very knowledgeable and kind. He helped my prioritize what services and repairs to tackle so that I could better plan for the future.

    • The 3 man crew arrived on schedule and did a quick survey of the equipment and all the duct work in the house. They all wore protective covers over their shoes and laid down protective cloths on the hardwood to protect from the heavy equipment they needed to bring in. I was advised that the overall project would take about 8 hours, as they had to tightly seal all the ducts after cleaning them in order to inject the sealant material to stop the loss of heat or air conditioning from the seams and joints in the ducts. I was able to step out for a couple of hours while they worked without worry, based on past experience with the company. After they completed their work, they showed me the before and after readings of the air loss, indicating a better than 90% reduction. They cleaned up all their work and left the house as they found it. All 3 members of the crew were friendly and professional. I'm very pleased with the work.

    • It's summer in the Midwest. Air conditioning is mandatory, not an option. One Hour handled everything from scheduling the appointment, following up to confirm the meeting the day before, and phoning the morning of to calibrate expectations the service tech would arrive at the scheduled time. The service tech quickly identified the problem and made the repair. He also cleaned the outdoor unit. This company is noticeably more professional than many. Jose was the service tech. I've requested a follow-up with him next month to prepare for the cold weather.

    • Joe and Art did a great job. Very professional and great work ethic. Couldn't be happier with the service and job they did. Replaced old boiler and installed new state of the art equipment. Big job. Kept me informed throughout. Highly recommend these guys.

    • Jose's furnace maintenance was apparently very thorough and he left me a very detailed report along with recommendations for future maintenance issues. I am very satisfied.

    • Our 3 year old AC unit stopped working and we were told it was an electrical issue. This meant possible cutting into the wall/ceiling to re connect a wire between the furnace/AC.  Jeff from One Hour Heating came out and was able to find the problem and have it fixed within 10-15 minutes. We had a clogged floor drain with some backed up water which tripped the safety switch, turning the AC off. He cleared the drain and all was good! This could have been very expensive and I am thankful Jeff was able to figure this out with a less expensive/messy way!! We have used them for years and have always had great service!!

    • Have been a customer for many years. They have installed 6 furnace / air-conditioning units in 3 houses and have serviced them for all these years without ever a call back. I can highly recommend the organization, When I moved into a townhouse I was not happy with the unit that was in place so I had a 2 stage furnace / air conditioning unit installed. Took 8 hours and Joe, the installer, did a wonderful job. Each of the service people I had, have taken their time and did a great job. Can't say enough about the whole organization.

    • Jeff was outstanding.  He did a comprehensive assessment and maintenance of my boiler and explained everything.  He also stabilized my wobbly wall-mounted thermostat without charge!  Highly recommend!

    • Gerald was great! Thorough, professional and explained everything so we could understand it. He took his time to listen and address each of our concerns and made sure that we were comfortable with the solutions before he left! One Hour Heating & Air are the only company we ever use and trust!!!

    • Gerald was extremely professional and friendly. He made sure to thoroughly explain everything to me and gave me good tips on how to keep my furnace running properly. Truly OUTSTANDING!!!

    • Dan is certainly a genius technician!He is kind, pleasant and polite.He gives great suggestions about keeping things in running order.And he was able to fix my air conditioner cover with some screws and Gorilla glue!He has visited our home before and we are grateful for his expertise and experience!Thank you Dan!

    • Great communication, great service. Dan was courteous and efficient, fixed the problem and checked and serviced the system properly in a timely fashion. Will recommend this company to anyone!
