"Another HVAC company diagnosed that my AC unit had a leaking evaporator coil after doing a pressure test, they quoted me over $1900 for labor and installation, claiming that my evaporator coil part was difficult to get a hold of.  I called up several other highly rated HVAC companies on Angie's List, all of whom told me that the part would not be difficult to get.  However, some were booked past Memorial Day, and others stated that they couldn't give me a quote unless they came out to actually look at my unit.  All Temp was the easiest to deal with and the most reasonably priced!  I called on May 22nd, they said they could come by on the morning of the 24th, I gave them the measurements and requested specs of my unit over the phone, and they quoted me $1075 right on the phone.  Troy came by on Saturday morning and installed the evaporator coil efficiently, and the price quoted was the price paid.  Couldn't have been an easier transaction.  He also could've been like the original company, who recommended replacing my units to try to get more money from me, but he was extremely honest and told me that with the new evaporator coil in there, I should be able to get many more years out of my unit and shouldn't even think about replacing it.  Thanks for your honesty and great service at a great price!

"I called Mr. Duct to clean my air vents and furnace after closing on my home. They were able to get me in the same week of my closing and communicated with me up until the technicians arrived at my house. The service I received was great. The technicians, Marcos and Fernandos, were knowledgeable, professional and explained everything very well. I am pleased with the work they did and the care and diligence they took with making sure to keep my home clean as well. I will definitely be using your company again in the near future."

"I had a great experience with their HVAC services. They repaired my electrical baseboard heater quickly and made sure everything was working perfectly before leaving. The team was professional, punctual, and very knowledgeable. They also installed our new central A/C system smoothly with no issues at all. Communication was clear throughout the process, and the pricing was fair. Highly satisfied with the quality of work and customer service. I would definitely recommend them for any heating or cooling needs."

"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."

"One hour heating of lake villa went above and beyond. Furnace was making load noise when it kicked on. Completely obvious he knew what he was doing. They repaired it, checked for other signs of issues, and cleaned up the furnace. The cleaning was a job on its own since it has not been serviced or cleaned in about 8 years. Customer service was outstanding and understanding. It s a new home to us and in the past I always used to call the company with the sticker on furnace from previous owners. I will be using one hour heating from now on for all my Hvac needs. Thank you"

Heating and Air Conditioning questions, answered by experts

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
