"Replaced capacitor. Still didn't work, so we were looking at ac replacement. Before we did, technician continued to experiment by cooling of the compressor with the garden hose and it worked! Saved me thousands in replacement costs."

"Andrew and his assistant were very professional in their approach to cleaning our air ducts and dryer vent. The services they provided were totally consistent with how they describe their approach to the service they provide. This included the very helpful before and after pictures taken which would convince anyone of the need to have this work performed in their homes."

"They were able to send out a tech to repair our AC pretty quickly (within a few days), even though this was during a bout of unusually high temperatures. The tech arrived towards the end of the given arrival window; even though he was still within the window, they called me that day to let me know he would be later rather than earlier, which was nice. The tech diagnosed the issue, and discussed options with me and fixed it (low line refrigerant, possible leak). All that was great, and prices seemed reasonable. The only negative part of the experience is that there was an extra charge to de-ice the frozen interior coils. I could have done that in advance if I knew I was supposed to (the tech seemed surprised I hadn't, or that I wasn't told to). Maybe that's obvious to others, but it's not that big of a deal, just an an annoying extra cost."

"They came even at a busy time to assess what needed to be done. I was given plenty of information and my questions were answered. I expect tomorrow’s furnace instsall will go just as well. I have had ac units and furnaces installed by Miller and been very pleased. A fine company."

"I hired this company to clean and check my Air Conditioner for the summer. The service tech was on time, friendly and knowledgeable. He took time to explain everything by showing me what levels my unit was at vs where it should be and gave me good recommendations on maintenance. He performed the necessary work in a timely manner and at a reasonable cost. I would recommend Best Rates Heating and Cooling for all of your HVAC needs."

"The men were very professional and fair. They tried very hard to fix the AC but the unit was deemed beyond repair. It was leaking coolant somewhere. They said they could give me a very good deal on a new AC with all parts and labor included if and when I choose to replace the AC unit with them. Even though the unit was not fixed because it was frankly beyond repair, I am still satisfied by their dedicated effort, honesty and professionalism. I will most likely buy a new AC from One Hour AC of Naperville in the near future."

Air Conditioning FAQs, answered by experts

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.
