"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

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.
