Air conditioning and refrigeration are provided through the removal of heat. Heat can be removed through radiation, convection, or conduction. Refrigeration conduction media such as water, air, ice, and chemicals are referred to as refrigerants. A refrigerant is employed either in a heat pump system in which a compressor is used to drive thermodynamic refrigeration cycle, or in a free cooling system which uses pumps to circulate a cool refrigerant (typically water or a glycol mix).

In 1992, a non-governmental organization, Greenpeace, was spurred by corporate executive policies and requested that a European lab find substitute refrigerants. This led to two alternatives, one a blend of propane (R290) and isobutane (R600a), and one of pure isobutane.[18][22] Industry resisted change in Europe until 1993, and in the U.S. until 2011, despite some supportive steps in 2004 and 2008 (see Refrigerant Development above).[27][67]

The customer service person on the phone was very pleasant. About an hour later a technician arrived even though it was 9pm at night. The technician seemed very experienced and thorough. He found the problem right away, but spent additional time looking over the entire system to make sure nothing else was causing other problems. He then explained the repair and gave me the price to make the repair, and asked for approval before moving ahead with the repair. The price was very reasonable, and it was repaired within an hour. I highly recommend AND Services!


Some service providers may recommend repairs and maintenance tasks that are not needed. A savvy consumer who has researched how an HVAC system works and is familiar with most common maintenance tasks will quickly know the difference between necessary tasks and add-on services that drain the wallet. If a heating or cooling problem occurs, appliance service manuals typically contain troubleshooting tips and other information that may be helpful in identifying or even resolving the problem without calling a repairman. Online HVAC guides may also be helpful to a consumer who wishes to become more familiar with how an HVAC system works and potential signs of disrepair. 
We will get into specifics later, but there are plenty of recommended maintenance items all homeowners should strongly consider if you want you to extend the lifespan of your AC unit. Furthermore, regular maintenance prevents certain repairs less organized homeowners see every few years. Some easy and highly recommended AC unit maintenance tasks include:
Perhaps the most sensible way to cool your home is to use your home's heating apparatus. Heat pumps can work in exactly this fashion. This device exchanges warmer and cooler air particles between your home and the outside air, allowing you to create a comfortable environment inside your home without the need of generating your own source of heat and cold. The one major drawback of heat pumps is that they tend to be inadequate in extremely cold or hot temperatures, which Portland essentially never sees. The only reason many homeowners don't have heat pumps in their homes is that they already have a forced air heating system. Thus, the best time to install air conditioning for your home is when your heating system fails.
This problem can be caused by an air-conditioning system that is too large for the house. If your system has always failed to dehumidify adequately, and it commonly short cycles (turns on and off frequently), an oversized system is ​a likely cause. An oversized system can cool the air so fast that the thermostat shuts off the system before much of the humid air has made its way across the cooling coil to get dehumidified.

This company was highly recommended to us by our realtor. Corey came out to do some work for us and he was really professional. He was on time, and explained everything he was doing and gave a quote (it actually ended up being cheaper!) before he started. He also looked at other stuff for us, and we got the feeling he was being honest and not pushy with his recommendations. We've already booked another appointment to fix some other things, and we requested Corey to do it.

After my initial meeting with HVAC Service I had really high hopes and thought these guys were going to be my HVAC go to company. However, it did not pan out this way whatsoever. Initial estimate meeting - This was the initial meeting I thought I found the go to company. Alberto was friendly, punctual, and knowledgeable. I asked some very basic questions and Alberto was able to explain the why's and why not's of each of my questions. Overall I felt really comfortable with Alberto and was extremely impressed. Then it goes all downhill..... Alberto said they were busy but could either install on the upcoming Saturday. We were going to be out of town and said unfortunately that day did not work. He then proposed the upcoming Tuesday as a possible solution, but just had to confirm with another appointment. I said great. I will review the estimate and call your office to confirm I want to move forward with the install. Within 1-hour of Alberto leaving (probably more like 30 minutes) I called the office to confirm I wanted to move forward with the install and to please confirm that Tuesday will be the install day. The lady on the phone said that she will get in touch with Alberto and call me back. This was on a Friday. On Monday I had not received a call from HVAC Service so I called to follow up. The lady on the phone said they were not able to secure a crane for Tuesday and that the install would not be taking place. Fine, no problem I understand. Two weeks go by and no phone call from HVAC Service regarding install date, or any update at all. I call them to check in to see if they have put me on the schedule and when I can expect to have the AC installed. You can tell by the discussion I had with the lady on the phone that they completely forgot about me and have not scheduled anything. She says she needs to get in contact with the owner because she has no idea on the availability of the crane. I was told that she would call me back by the end of the day with an update. Surprise, surprise, no phone call. I call to follow up at the end of the next day and she said that she has not been able to get in touch with the owner. By this time, I am starting to get frustrated because I am starting to get the run around. I question her if I am even on the schedule or if they attempted to schedule a crane. She says they are extremely busy and that she does not know. So I say, basically I have waited over 2 weeks and you have not put me on the schedule and I am at the end of the install line. No answer. I tell her to talk to her boss and find out what is happening, and I will think about what direction I want to move in at this point. Monday the following week, no phone calls, or follow up. I call to get an update and am told that they cannot install my system because they don't have time. I ask what does that mean, one year? One week? Until the end of summer they say. What does that mean I ask? They say at the end of September. I say thank you for wasting 1 month of my time. How could they have served me better without serving me? 1. Be honest and let me know as soon as possible that the install was going to be delayed and probably not happen until the end of summer. Don't waste a month of my time. I could have reached out to a different company in the time I was waiting for them. 2. Communicate! the thing that upsets me the most is I was the one making all the calls to them. Not once did they ever call me to say we have not forgot about you, or this is what is happening. 3. Provide recommendations on other contractors who could have helped me once they realized they were too busy. I am pretty disappointed it came to this review because I really liked this company and wanted to do work with them. It is a family run business, and reminded me of the HVAC business my dad owned. Beware once you are the one that has to start calling them for updates, or to follow up; your time is probably best served by calling a different contractor.
Special chemicals can be used to clean mineral deposits, but one of the safest is vinegar. A 50% mixture of vinegar and water will usually dissolve or help clean away deposits. If the humidifier has a drum with a belt, replacement of the belt at the beginning of the heating season can be the easiest fix if the water has a high mineral content. If the humidifier has screens or is the wick type, some corrosion can occur as well as build up
AC units and thermostats have built-in delay features when they’re shut down and then repowered. The delay can be as long as 10 minutes. And, if you’ve subscribed to an energy-saving device from your local power utility, the unit can take even longer to reset. If you’ve installed the parts shown and reinstalled the disconnect block, repowered the circuit breaker, turned on the switch at the furnace, moved the thermostat to AC mode and lowered the temperature below the indoor temperature, and the unit doesn’t fire up after 30 minutes, it’s time to call a pro.
