I called on December 25th at midnight and started leaving a message and Thomas Hoffman the owner called me back almost immediately. He said he would come out the next morning between 8:00 and 10:00 am snd he was promptly on time. He fixed my problem and while he was there I decided to get an estimate for a new furnace and air conditioning unit. The price was very reasonable and the installers one of them being his son were both very professional very courteous, polite, arrived on time and finished the same day. I enjoy knowing that I now have the support of Thomas Hoffman heating and air conditioning along with the peace of mind that comes with owning a Trane. Nothing stops a Trane.

Nick was excellent. Super profession, quick, and up front with the pricing (which was fair). Hopefully we don't need to call anyone to fix our AC again, but if we do - I'm calling Nick!
Response from the owner:Thank you, Layton, for your amazing review! We really appreciate your support and hope to be your first call for any future repairs!
Same day service. Technician arrived as scheduled. Replaced capacitor quickly. Friendly technician. Repair cost $429 seemed high for inexpensive part and 20 minutes labor.
Response from the owner:Thank you, Tom, for your feedback! We're glad to hear the technician was prompt and friendly, though we understand your concerns about the repair cost. We appreciate your insights and hope to serve you again in the future.

My ac compressor was replaced.

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.
