"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"I have been a Four Seasons customer for about 20 years, and normally I have been very pleased with their performance and responsiveness. This last encounter has been a disaster from the start as described below. I am happy to say however, that Four Seasons Customer Service reached out to me to rectify the issue, which was satisfactorily enough for me to revise my rating. My AC issue was mis-diagnosed resulting in unnecessarily having to endure 90 plus degree temperatures for four days. Mind you, this occurred 5 weeks after my tune up. I was told the compressor needed replacement, then my appointment to install a new one was cancelled because the parts were not in and nobody notified me. The first person I spoke to about the missed appointment gave me an attitude and no resolution. Second diagnosis by two technicians was the coil had a leak. Another day of 90 degree waiting and had the coil replaced by a third technician. I am still not sure that my AC has been fixed however because after three hours of running the unit it did not feel like it was blowing cold air as it used to. Hard to tell as the temperatures have been too low to use the AC. Hopefully we will have a warm spell so I can know for sure and I will change my review to recommend."

"I had the most positive experience working with Bob and Anthony on a full Furnace/AC installation. Both systems were approaching 15 yrs old needing repairs that would not have made sense to continue putting money into. Bob came onsite for a free consultation and very clearly communicated detail on my options, even making recommendations for further cost-saving improvements. They fit me in right away and worked diligently with the installation. I couldn't be happier with the end result...should have called these guys months ago!"

"ThermaTek Heating and Air - Jamey Jamrosz, HVAC Specialist/Owner gave me a quote over the phone. I agreed to have him come for any evaluation of my AC. He arrived within 3 hours of my call. After checking everything out, he explained my options and the cost of each. I decided to go with the repair option, which he proceeded to complete the same day. Jamey was fast and personable. I will follow up with him for my HVAC needs for my condo. I will recommend him to my condo neighbors."

"We would absolutely hire Toptec again. They were easy to contact and set up time with for our appointment. The man that came to our house, (Dr.)Dre, showed up promptly and was extremely knowledgable and friendly. He took the time to literally explain every piece of our furnace, humidifier, and air conditioner (we're new homeowners) and answer any questions we had for him. He examined everything quite thoroughly and gave recommendations for any parts that needed replacing. You can tell that he is passionate and knowledgable about what he does. He even took the time to power wash down our air conditioner and remove a lovely dead mouse that was stuck in there. I will definitely be requesting Dre to come back for anything we have done! Thank you!

Air Conditioning questions, answered by experts

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

The cost to repair an air conditioner averages around $350 to $450, but the price can range from $100 to over $3,000. The final cost depends on the type of air conditioner, the extent of the damage, and the specific parts that need replacement. For example, repairing a window AC unit typically costs between $100 and $250, while central air conditioner repairs can range from $300 to $3,000. A simple fix like replacing a dirty filter might only cost $10 to $50, but a major issue like a broken compressor could cost around $2,000 or more, potentially making it more cost-effective to replace the entire system. Due to the need for specialty tools and handling of refrigerants, repairs more complex than changing a filter are best left to a professional.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

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.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.
