Thomas is amazing and came over in only a couple hours and fixed my ac! True life saver 🙏🏼
Response from the owner: Thank you for sharing your experience with Thomas! We're glad to hear he was able to help you out quickly and efficiently. 👍
Fantastic experience! Our AC went out on a scorching Saturday evening. I wasn’t actually expecting anybody to get out that night, but when calling - I immediately got an answer, was on the schedule in 5 minutes, and Thomas showed up an hour later. He was honest, professional, and educational. Most importantly, I didn’t feel like he was cutting corners or trying to get in and out… a welcome contrast from most services these days. 6 stars out of 5, highly recommend.
Response from the owner: Thank you for sharing your experience, Andrew! We're so glad to hear that Thomas provided such honest and professional service for your AC needs. We truly appreciate your recommendation and look forward to serving you again in the future.

Thomas Hoffman was originally recommended to me by an "insider" in the HVAC field, and it's one of the best referrals I've ever gotten! I've now been using them for four years, and two different homes. They are responsive, prompt, professional, and kind. They are also reasonable in their rates and honest in their assessments--no scammy upselling here! Most recently our AC went out over the weekend, and I called on a Sunday, expecting to leave a voicemail and hoping for an appointment within the next several business days. Instead, Nick Hoffmann answered right away, and he was at my house within the hour! Diagnosed and fixed the problem within another hour! They've definitely earned my trust, my thanks, and my business.
Response from the owner: Thank you so much for your kind words and continued support, Douglas! We truly appreciate your trust and are grateful for the opportunity to serve you.
The service was great. The installers and guys that brought the materials needed were great. Cleaned up afterwards and answered any questions that I had. Would recommend.
Response from the owner: We're so glad to hear that you had a great experience with our team! Thank you for recommending us.
The staff was very professional and friendly. And they took no Tim at all to find and fix the problem with my AC. I would highly recommend to my family and friends.

Thomas came through in a pinch when our air went out on a weekend. Even with the emergency fee, his rates are very reasonable. It was a simple part replacement rather than the whole unit, which we thought might be necessary. I can’t say enough good things about Thomas. We will certainly use him again!
Response from the owner: Thank you so much for your kind words, Catherine! We truly appreciate your feedback and are glad we could help. Looking forward to assisting you again in the future!

Your air conditioner can be a lifesaver during warm and hot seasons, but if not properly maintained, it can also be a nuisance. You may start hearing mysterious noises from your unit.
Sometimes the noises can be harmless. Other times the noises could be a sign of major mechanical issues. Let’s take a look at some of the most common AC noises and why they happen:
Rattling/Clicking
If your AC unit is making rattling or clicking noises, it means there’s something loose. If the rattling sound happens when you turn on the AC and continues once the unit is running, it could be a loose part in either the blower wheel assembly or the motor. It could also be a sign of debris in the drain pan.
If your rattling is coming from a different component, like the coil, then there’s an issue with the refrigerant flow that will require professional help.
Screeching
If your air conditioner lets out a loud screeching sound, it’s probably because the fan blades are hitting something. It can be anything from debris in the blower wheel assembly to the center brace on top of the unit.
You may also have some rust build-up that has allowed the fan blades to make contact with a metal part of your air conditioner. The good news is that screeching doesn’t cause any permanent damage, but it still means there’s a problem with the fan blades, and you’ll need to seek professional help.
Humming/Buzzing
If your air conditioner is making a loud humming noise, it’s probably not moving enough air across the coil. As the AC unit sucks in cool air and pushes out hot air, there needs to be enough moving room for the internal coils of your AC system to work efficiently.
Clicking/Ticking
Unfortunately, clicking and ticking sounds are always a bad sign. If you’re hearing any of them from your AC unit, it’s either the sound of damage to the motor coil or compressor seal, both of which will require professional service. While the clicking/ticking sound indicates something wrong, the good news is that it means your compressor is still working correctly.
Rumbling/Grinding
If you hear a rumble from your air conditioner, there may be an issue with the fan motor, and it will need replacement. You might also have some foreign objects lodged in your AC unit (such as construction debris or a large bug) that make the motor work harder than it should.
If your air conditioner rumbles for more than a second or two at a time, then you probably have something stuck in the fan blades, and it will need removal.
Get Professional Help
If you notice any of these noises, call an HVAC technician immediately so they can help you fix the problem before it turns into a severe problem that could be difficult or more expensive to fix.
