"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."

"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."

"The air duct cleaning aspect was good. I had issue with a few minor things that happened while the service was performed. Tom from Mr. Duct, quickly responded to my concerns and remedied them as best he could. The workers arrived on time and on schedule, were polite and quickly got to work. I discovered the issues (minor) after they left, but Tom quickly followed up with me. I will probably use them again as they took the time to make sure I was satisfied"

"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."

"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."

"Serviceman was prompt, cordial, listened to my concerns, understood that it was the same exact issue as last year, tested the Freon level, acknowledged that it was low and added Freon.  
My issue was with the bill.  I was charged a $96 "Service Fee", $150 for 3 lbs of Freon and $48 labor.  The serviceman was only here for 30 minutes.  I called to find out what was included in the "Service Fee" and was told that this was just to come out to my house and diagnose the issue.  I told them that I already knew what the issue was (they had performed this service for me last year and told me that they would need to come out and add freon every summer until we decided to replace the unit) but that did not matter.  I asked them why 30 minutes of labor was not included in the "service fee" and they told me that was not what they do.  Even when I go to the auto repair shop and they charge a "diagnostic fee", some of that is applied to the labor if I have the work performed.  To me this is just taking advantage of the customer who needs his A/C fixed on a hot day.  When I spoke to the service manager, if he had just offered to waive the $48 labor fee, I would be writing about how TR Miller listens to their customers concerns, understands the situation and makes the right adjustments based on the situation, not just following the status quo.  TR Miller's inability to "step out of the box" is now going to cost them a $5K air conditioner sale as we will likely replace the unit next year.  We will be looking for better "partner" to bring our business to."

Air Conditioning FAQs, answered by experts

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own. 

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
