"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"After reading reviews on Angie's List and finding out that they do installations for Costco, we chose Around the Clock (even though they were the most expensive of the 3 quotes we received) because we wanted to make sure we did not skimp on such a major project - installation of a new HVAC system. While the system is working great and our house is much cooler than with our swamp cooler and/or window AC units, we were disappointed with a few aspects of the job. As far as when the crew was on the job... they were on time, clean, and the job got completed in the time that they said it would - 2 days. My concerns came up in the days/weeks after the job was completed when a contractor came to the house to look at some additional work being done. Part of the quote from our job was that they would "remove" two existing floor gas heaters in our home. When the contractor and I were looking at repairing the hardwood floors where the heaters have been removed, we found that one of the heaters had actually just been left under the house in the crawlspace. A few minutes later, I asked my contractor to check out the attic because I knew that the workers had smashed an asbestos vent pipe from one of the old heaters so they could run electric wires through it from the crawlspace under the house up to the attic and eventually the package HVAC unit on the roof. I know that health issues arise with asbestos when it disturbed (like smashing it apart and leaving it exposed in the attic.) The contractor confirmed that this was the case and he was rather alarmed and surprised that a "retail" top-dollar job had been done with these methods. After talking with the owner, Alan, about my concerns, his response was basically this is the way that things are done. He said that leaving the heater under the house is called "dropping" the unit and that the unit was too big to remove out of the crawl space. I think that with some effort and a Sawzall it could have been removed, but either way, I wish that they would have been clearer that they were leaving smashed up appliances under our house. I told him about the asbestos pipe and he told me, again, often times that is "how it's done" because it's the easiest way to get the wires through the house. When I told him I had safety concerns about the asbestos being exposed, he said that the workers should have put some kind of coating on the exposed areas as a protection against any of the asbestos fibers getting airborne. I sent him photos confirming that there was no coating applied. During this call, he mentioned something about "sealing" the unit to the roof (to protect against rain penetrating where the HVAC and the roof meet) and that it had not been done yet because they thought maybe we were getting a new roof very soon. This was the first I had heard that the job was not complete and I don't know where the idea of the new roof came from other than our roof is old and going to need to be done in the next few years. Alan said he would send out someone to coat the pipe and do the roof "sealing". They came out that day or the next to do the work. After talking to the worker about the pipe (same guy who was heading the crew on the installation days), he acted like this was a waste of time and told me, "We never put this coating on these asbestos pipes when we break them." That was disconcerning and it made me feel like the owner doesn't really know what his crews are/are not doing or, more likely, that they just are doing whatever they need to do to get the job done quick, cheap and easy. Overall - the big disappointment for me and my wife... if we wanted the job to be "quick, cheap, easy, and maybe cut a few corners, we would have gone with a different HVAC company that was much cheaper, and we would expect that because "you get what you pay for", but we didn't, we went for the retail installer and feel that the job was less than retail."

"The technician came and evaluated our problem which we thought was heating and air conditioning but we were told that the heating was very good but some part went out on the air conditioning unit. He was honest and took the time to explain what we did not need and made sure we paid for only what was wrong with the unit. We are signing up for the preventive maintenance program. Sorry I can't remember the nice man's name but he was wonderful."

Heating and Air Conditioning questions, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.
