"Excellent. The service rep gave me many helpful maintenance tips to keep my HVAC appliances in top condition. He was prompt (actually early), well-organized, and communicated his findings well. I would definitely use All Temp again."

"Highly recommend. Found this company last year on Angie's List and this is the second time using them. I was in a pinch as the A/C went out and we have a little baby. I called and they got someone out the same day. Jeff was great...knowledgeable, friendly and answered a lot of questions! Got the unit working again! These are my go-to HVAC guys!"

"Initial estimate was scheduled with no problem, they took the time to answer all the questions I had about the furnace replacement. I received estimated from 6 other HVAC companies and American Family was basically the lowest, but I also felt comfortable with the level of knowledge and experience that was conveyed at the estimate. I scheduled the install and was a bit disappointed that the installers did not show until 10 am or so, but that was not a big problem as I had assumed the job would take all day. The job took longer than expected (past 7pm) and the installer wound up having to replace an entire part of the intake duct work that he did not expect to, but in the end the unit and ductwork looked clean and sturdy and well intalled. The owner called for a follow up appointment and he came in to look at the install and make sure all the settings were correct on the furnace. He answered any questions I had at that time. All in all a good experience with a good company"

"Rick came to my home and gave us a proposal to remove and replace our old furnace and electric water heater. His cost was more than fair. Craig came early on the scheduled day. In no time he had the old equipment removed. The new equipment installations were all completed the same day. My experiance with C.R. Mechanical Services was better than expected. Rick and Craig were both friendly and professional through-out the whole project. I will highly recommend them for anyone in need of a HVAC contractor."

Heating and Air Conditioning FAQs, answered by experts

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.
