The repairman arrived at around 8:30 AM and spent about three hours working on the unit, which I purchased from them less than a year ago. At the end of three hours, he informed me that my unit was not working because I had the wrong filter in it. I raised a question about why it took three hours to replace the filter. I can't really explain his response because it was in technical jargon that I did not understand well enough to know what other questions to ask. The unit has a two year parts and labor warranty and a 10 year manufacturer parts warranty. unfortunately, I did not get the benefits of those warranties because, as the technician put it, the onus for using a less effective filter, rests with the customers. Then, he went on to describe to me the best filter choice, something the average customer would not automatically know. My greatest disappointment was being denied the benefits of my warranties. On the plus side, once management became aware of my dissatisfaction, they reached out to me with an apology for any role they played in my dissatisfaction and, as a show of their good intentions, they shredded my check, subsequently, not charging me for their service. This response showed a genuine commitment to quality and efficient service, as well as a commitment to customer satisfaction. Consequently, I highly recommend Hoffmann Air Conditioning services.
Response from the owner:Thank you, James, for your 5-star rating; we truly appreciate your support!

I was distraught to find out our 20 year old HVAC needed to be replaced. Hoffman was beyond empathetic and took care of me within 24 hours during the heat wave. They were on time and very efficient. I have to have trust worthy people work on our house and be in our cocoon, therefore Hoffman has always been our contractor and always will be! They have become family;) I refer all of my clients to them!!!
Response from the owner:Thank you, Katie! We're so glad to hear that you felt supported during a tough time. Your trust means the world to us, and it's wonderful to know that we’ve become part of your family. We appreciate your referrals and look forward to continuing to serve you and your clients!

Technician, Giovanni Leone, did such a great job in fixing our AC on a Saturday morning when the Temp is supposed to get up to 100 degrees, later today! I felt like we were in excellent hands and he explained everything he was going to do and then explained in even greater detail once everything was done! I told him if he ever wants to go into sales, he should! He has great personable skills! We have used Thomas Hoffmann before for our heating and cooling needs and they are always professional and trustworthy! My only mistake was not having them to come out to check our AC in the past 3 years!
Response from the owner:Thank you, Bill! We're so glad to hear about your positive experience with Giovanni. It's great to know that you felt well taken care of and appreciated his thorough explanations. We truly value your trust in us for your heating and cooling needs, and we look forward to serving you again in the future!

Why Clean AC Coils Matter

Your air conditioner’s coils – both the evaporator coil (inside your home) and the condenser coil (in the outdoor unit) – play a vital role in the heat exchange process that cools your home. Over time, these coils can accumulate dust, dirt, and debris, significantly impacting your system’s performance. Here’s why clean coils are crucial:

  • Improved Energy Efficiency: Clean coils allow for better heat transfer, meaning your system doesn’t have to work as hard to cool your home.
  • Lower Energy Bills: An efficiently running AC uses less energy, potentially reducing monthly utility costs.
  • Better Cooling Performance: Clean coils help your AC maintain consistent cooling throughout your home.
  • Extended System Lifespan: Regular coil cleaning can help prevent unnecessary wear and tear on your AC system.
  • Improved Indoor Air Quality: Clean coils contribute to cleaner air circulation in your home.

The Professional Coil Cleaning Process

While some homeowners might be tempted to clean their AC coils, this task is best left to professionals. At Thomas Hoffmann Air Conditioning & Heating, our technicians have the training, experience, and specialized equipment to clean your coils thoroughly and safely. Here’s an overview of our professional coil cleaning process:

  • System Inspection: Our technicians thoroughly inspect your AC system before beginning the cleaning process. This allows us to identify any other issues that may need attention.
  • Power Down: We ensure the system is entirely powered off for safety reasons.
  • Coil Access: Our technicians carefully remove any panels or components necessary to access the coils. This step requires expertise to avoid damaging sensitive parts of your AC system.
  • Dry Cleaning: We dry the coils using specialized brushes and vacuum equipment to remove loose debris.
  • Application of Cleaning Solution: We apply a professional-grade, environmentally friendly cleaning solution designed specifically for AC coils. This solution helps break down stubborn dirt and grime.
  • Agitation: Using soft brushes or low-pressure sprayers, we gently agitate the cleaning solution to ensure it reaches all areas of the coils.
  • Rinse: We thoroughly rinse the coils with clean water, removing all cleaning solutions and loosened debris.
  • Drainage Check: Our technicians clean the condensate drain line to prevent clogs and water damage.
  • Reassembly: We carefully reassemble any components we removed for access once the coils are clean and dry.
  • System Test: Finally, we power up your AC system and run it through a test cycle to ensure everything works correctly.

The Importance of Professional Service

While DIY guides for coil cleaning exist, entrusting this task to professionals like Thomas Hoffmann Air Conditioning & Heating offers numerous advantages:

Safety First

Our technicians are trained to handle electrical components and cleaning chemicals safely, minimizing the risks associated with DIY attempts.

Save Time, Avoid Hassle

Our experienced team efficiently cleans your coils, allowing you to focus on other priorities while ensuring your AC receives expert care.

Regular Maintenance for Optimal Performance

At Thomas Hoffmann Air Conditioning & Heating, we recommend having your AC coils professionally cleaned at least once a year, ideally before the start of the cooling season. However, more frequent cleanings may benefit homes with pets, smokers, or high dust levels.

By scheduling regular maintenance with us, including coil cleaning, you can enjoy the benefits of a more efficient, longer-lasting AC system. Our maintenance plans are designed to keep your system in top shape year-round, potentially saving you money on energy bills and costly repairs down the line.
