An important component of natural ventilation is air change rate or air changes per hour: the hourly rate of ventilation divided by the volume of the space. For example, six air changes per hour means an amount of new air, equal to the volume of the space, is added every ten minutes. For human comfort, a minimum of four air changes per hour is typical, though warehouses might have only two. Too high of an air change rate may be uncomfortable, akin to a wind tunnel which have thousands of changes per hour. The highest air change rates are for crowded spaces, bars, night clubs, commercial kitchens at around 30 to 50 air changes per hour.
Air Conditioning Service Repair - No matter what name brand (York, Trane, Carrier, Goodman, Lennox, Rheem) of air conditioning and/or heating unit you purchase some time or the other you will need to have that air conditioning and heating equipment checked for a problem and repaired. Even if you have regular air conditioning maintenance done. While there are air
The Chartered Institution of Building Services Engineers is a body that covers the essential Service (systems architecture) that allow buildings to operate. It includes the electrotechnical, heating, ventilating, air conditioning, refrigeration and plumbing industries. To train as a building services engineer, the academic requirements are GCSEs (A-C) / Standard Grades (1-3) in Maths and Science, which are important in measurements, planning and theory. Employers will often want a degree in a branch of engineering, such as building environment engineering, electrical engineering or mechanical engineering. To become a full member of CIBSE, and so also to be registered by the Engineering Council UK as a chartered engineer, engineers must also attain an Honours Degree and a master's degree in a relevant engineering subject.

There is nothing worse than having your air conditioner break in the middle of a long, hot summer. You can ensure your air conditioning unit stays in working order all year long with regular service. Sometimes, however, repairs are necessary whether it’s fixing the evaporator, capacitor, or condenser or recharging the refrigerant. Most air conditioner repairs cost between $163 and $528 with most homeowners reporting that they spend about $344. If you do need a repair, here is some information to help you get it done quickly, professionally, and economically.
Change the filter: A new filter can cost as little as $20. Since this is the most effective way of maintaining your AC system, there is no reason not to change your filter. Homeowners should change your AC filters whenever it gets dirty. Depending on the filter, you may have to change it once every six months or once every month. Each filter should indicate how long it will last.
I originally took off one star because of the SNAFU with getting the part ordered. When Alberto called me on the phone he admitted the person had "gotten busy with other things" and apologized. THAT was taking the high road and I was impressed by that. Sadly, for reasons I won't guess at, Alberto has decided to take the low road in his comments and imply that they got the part as quickly as possible. Well, we called at 2:30 so did someone spend six and a half hours finding the part?? That seems very doubtful.

Consequently, this water must exit the air handler—typically through plastic pipe or a drain tube. That drain tube goes directly outside, often terminating near the compressor, or to a floor drain or to a small electric “condensate pump” located by the air handler. Where a condensate pump is used, it connects to a 1/2-inch vinyl or rubber tube that exits outdoors or to a drain.
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.
Ductwork pinging or popping. If you hear a pinging or popping sound coming from metal ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal. Track along the duct runs, listening for the sound. If you find it, make a small dent in the sheet metal to provide a more rigid surface that’s less likely to move as it heats and cools.
Wow! These guys rock! I had issues with our fireplace for a while and the last company who "fixed" the issue basically charged me a lot of money and literally left me standing in the cold. Next they said it would cost me over $700 to fix the whole thing and they never came back. Finally I was able to find some good guys to fix the issue. Tony and Paul from HVAC were not only really friendly, they diagnosed the issue really fast and fixed it the same day. And it was 7 times less than what the other company asked for!!! Next time I know who to call! 5 Stars!
Before opening the electrical cover on the A/C unit, be sure to shut off all power to the compressor unit and the indoor furnace or air handler, and verify that it is off. Note that this may mean shutting off a circuit breaker that serves the furnace and air handler, and then, near the compressor, pulling out the disconnect block (or shutting off the 220-volt power) to the outdoor compressor.

If your AC doesn’t turn off when room temperature reaches the temperature set on the thermostat, the problem is generally occurring either at the thermostat or in the electrical system that runs the outside condensing unit. You can use the AC’s circuit breaker to shut off the unit, but that should not be a permanent solution—circuit breakers are not designed to be used like light switches.
The most recognized standards for HVAC design are based on ASHRAE data. The most general of four volumes of the ASHRAE Handbook is Fundamentals; it includes heating and cooling calculations. Each volume of the ASHRAE Handbook is updated every four years. The design professional must consult ASHRAE data for the standards of design and care as the typical building codes provide little to no information on HVAC design practices; codes such as the UMC and IMC do include much detail on installation requirements, however. Other useful reference materials include items from SMACNA, ACGIH, and technical trade journals.
Please note: this is a review from someone who never got service from here. They just chose to ignore my calls for a heating emergency. Who knows, they might have give great service, if they actually return a promised phone call. I actually call them this past Saturday night. It was chilly, we turned the furnace on...... Poof.... Nothing. So, I look them up on Yelp. Good reviews with a few bad goods added, plus a Yelp deal. I gave them a call, the at about 6 pm. I know, 6pm on a Saturday, who's going to come out, well, they did. They woman, I assume their receptionist, answers and I told her I need someone out here. She assured me someone will call me back in 15 mins. Half hour to 45 mins later, no calls from them. I figured maybe they wrote the number down wrong, it happens. So, I called them again. They got the number correct, got my name and address correct, and was told they will call me back in 10 mins. I even asked if this is something they don't do, as in services on a Saturday night. I was told by the receptionist that they do and I would just be ok calling another company if they is not part of their services. They again assured me someone WILL call me in 10 mins. Well, unless their definition of 10 mins is never, then they got it wrong as I am still waiting to be called 5 days later.
In the UK, the Ozone Regulations came into force in 2000 and banned the use of ozone depleting HCFC refrigerants such as R22 in new systems. The Regulation banned the use of R22 as a "top-up" fluid for maintenance between 2010 (for virgin fluid) and 2015 (for recycled fluid). This means that equipment that uses R22 can still operate, as long as it does not leak. Although R22 is now banned, units that use the refrigerant can still be serviced and maintained.

They did come out Tuesday and completed the job. We called the office to ask for a breakdown of the cost and they said the tech would call us back, but that never happened. Eventually Alberto called and explained the breakdown. One reason it was more was they used an OEM circuit board, rather than an aftermarket part. I agree with this but it would have been better if this had been explained from the beginning. All in all, it still seems like their price is a bit on the high side, but they did a good job and used OEM parts so I'm giving them four stars. Read more
As for parts prices, we are a business and factor in profit and overhead into our pricing structure, and frequently research other companies to be sure we are competitive, which we are. Jody, you did not pay $400 for labor, you paid $489 for a flat rate repair which included, travel, labor, diagnostics, parts, tax, shipping, truck charge, fuel charge, overtime rate, profit and overhead. As for the time of the actual repair, if it had taken 2 or 3 hours the cost would have still been the same $489.
All modern air conditioning systems, even small window package units, are equipped with internal air filters. These are generally of a lightweight gauzy material, and must be replaced or washed as conditions warrant. For example, a building in a high dust environment, or a home with furry pets, will need to have the filters changed more often than buildings without these dirt loads. Failure to replace these filters as needed will contribute to a lower heat exchange rate, resulting in wasted energy, shortened equipment life, and higher energy bills; low air flow can result in iced-over evaporator coils, which can completely stop air flow. Additionally, very dirty or plugged filters can cause overheating during a heating cycle, and can result in damage to the system or even fire.
All AC repairs were not created equal. While a new filter could cost as low as $20, a refrigerant leak repair can cost up to $1,600. Just like any aspect of the house, certain repairs will mostly depend on the damage. Clearly, the more serious issues will cost more. That not only means more time for the HVAC pro, but more complexity and materials as well. Sadly, neither come without a hefty markup.

Routine maintenance involves replacing or cleaning the filters if so equipped, and keeping the outside air intake free of debris. After years of service the air exchanger will become crusted with grease and dirt that collects during condensation. Removing this accumulation will probably take solvents or degreasers and require opening up the cabinet and compartments.

Even if your air conditioning unit is still working, depending on the type of system in your home today, you could recoup your investment in a new system in as little as three years. However, that doesn't mean that your system needs to be replaced. Furnaces, air conditioners, and other heating and cooling systems have made tremendous gains in efficiency over the past five years, so if you have an older unit, it is worth taking a look at whether or not a repair is the best investment.
Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season.

There is a premium for most any service company to come out afterhours or weekends, and being we are one of the very few companies to offer this service, a higher labor rate is understandable, after all, we have to pay our service persons an overtime rate for such calls.
You should have your air conditioning maintenance done at least once a year, in the spring. Doing it in the spring will allow your technician to repair any damage the unit might have acquired during the winter, and make it ready just in time for the arrival of warmer temperatures. However, it’s best to do maintenance twice a year: in the spring and fall. Sticking to this bi-annual schedule will keep your unit running optimally.

“We had a great experience with Robinson’s! The office staff, then the gentleman who helped me with questions over the phone and Kyle, our service tech, were all great and very easy to work with. They gave me a time frame for when to expect Kyle the same day. A phone call to let me know he was on his way. A text with picture so I knew who to be expecting. Kyle arrived on time and was very knowledgeable and friendly. He did a great job. You could tell he liked his job. Prices were reasonable. We will be using and recommending Robinson’s Air – Wichita Falls in the future.”
6) Check your ductwork and seal open spaces. Make sure all your doors and windows are properly sealed to help keep your home cool. Perform a visual inspection of your ductwork occasionally to be sure it is sealed correctly. If ductwork is not properly sealed, cool air will escape before getting into your home. The less cool air that escapes your home, the less your unit will have to work.
Are you considering whether you need to replace your home’s central heating, ventilation, and air conditioning unit—commonly known as your HVAC system? As a general rule, if your existing HVAC system is more than 15 years old, it’s only a matter of time before it starts to cost more to maintain than it would to replace it with a new system. In addition to higher energy bills brought on by a system that can no longer function at peak efficiency, repair costs will also start to add up as parts are replaced and the ventilation system undergoes major overhauls.
If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. Lastly, a good HVAC service tech will attempt to find the refrigerant leak within the hour’s air conditioning service you are paying for in addition to the refrigerant charge.
Installation—Having your HVAC systems installed by a professional is extremely important to prevent any future problems or needless repairs. Our professionals at Service Experts Heating & Air Conditioning can also help you choose what size equipment is appropriate for your house. Selecting a system that is too large or small can impact efficiency and add to your energy bills.
