"AC Dave is a skilled and trustworthy HVAC company that does quality work at a competitive price. I had an aging four ton system that was on its last leg. My funds were tight at the time, so they suggested installing more efficient ducting to extend the system’s life. That was three years ago, which allowed me to save for the inevitable expense of replacement. And when that time came, I was given a comprehensive estimate and the installation went smoothly. They also did a follow up to tweak the system for maximum reliability. AC Dave is a small company, so you may not get next-day service, but they will work with you and stand by their work. In today’s less and less neighborly world, that is a real asset."

"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."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

Heating and Air Conditioning questions, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.
