"They went above and beyond to get here quickly, and as it turned out, it ended up NOT to be the thermostat, but the technician, Rob, knew that the thermostat was telling him the problem was in the Air conditioner so he went out and investigated and found a mouse nest inside the unit—it had chewed through two wires. Rob fixed the problem, got it back to normal, and it works beautifully! I found both David and Rob very friendly. I'd use them again."

"We have a home warranty and placed a service call through our home warranty company for AC repair. In the 20 yrs. that we have owned our home, we have had 5 different HVAC companies come out on service calls or maintenance tune ups. Max-Pro Heating and Cooling is by far the best HVAC company we have ever had. Charity the office manager and scheduler gets 5 stars for her professionalism, concern for customers and downright great service!! She also kept me updated on when technician would be able to to come out. Sean the technician was very professional, extremely knowledgeable, hard working and did a superb job for us with great attention to details!!! He took the time out to explain what he was doing along the way. We were so happy and satisfied with Max-Pro that we completed a survey for our home warranty company and we gave Max-Pro several 5 star ratings. You can't go wrong with selecting Max-Pro and we would highly recommend them."

Air Conditioning FAQs, answered by experts

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.
