Absorption heat pumps are a kind of air-source heat pump, but they do not depend on electricity to power them. Instead, gas, solar power, or heated water is used as a main power source. An absorption pump dissolves ammonia gas in water, which gives off heat. Next, the water and ammonia mixture is depressurized to induce boiling, and the ammonia is boiled off, which absorbs heat from the outdoor air.[citation needed]

Are there watermarks on your ceiling? Visible leaks around your outdoor unit? Has your AC system completely stopped working? If you notice any of these signs, it’s in your best interest to call an AC technician to fix the issue before it causes more problems for you, your AC system, and your home. To learn more about potential AC malfunctions and how we fix AC issues, visit our AC Repair page.


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.
An air conditioner's filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. Check out our Energy Saver 101 Infographic: Home Cooling for more ways to help improve your comfort and the efficiency of your air conditioner.

The liquid refrigerant is returned to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is often called an evaporating coil or evaporator. As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air, returns to the compressor, and repeats the cycle. In the process, heat is absorbed from indoors and transferred outdoors, resulting in cooling of the building.

Absolutely horrible service dont show or call within there appointment window, half to blow up the o...wners phone after there appointment window to get any answers why. And then it takes another 2 hours for there tech to get there after you were told it would be only an hour. Horrible customer service even though it was a Saturday and they made the appointment. But the tech was very professional. Never recommend them only had to use them cause of insurance See More

    Second, there are the diagnostics involved as well as the return trip to effect the actual repair. What about the hidden costs such as having the part picked up at the supplier, was this considered? As for the parts manager at our shop having wasted time tracking the part down, it often happens that we have to contact several suppliers to find parts especially during the recent cold spell when so many suppliers were out of stock of even the most common service items due to demand being so high.

The manufacture and use of CFCs has been banned or severely restricted due to concerns about ozone depletion (see also Montreal Protocol).[63][64] In light of these environmental concerns, beginning on November 14, 1994, the U.S. Environmental Protection Agency has restricted the sale, possession and use of refrigerant to only licensed technicians, per rules under sections 608 and 609 of the Clean Air Act.[65]

Just like running a marathon, we perform better at full strength. If we’re not feeling great, it’s that much harder to finish the race. Similarly, when you set your thermostat to a certain temperature, the system is tasked with maintaining that temperature throughout the room. Working at full strength, the system can easily maintain that temperature (as long as it’s not below 60 degrees or above 80 degrees). However, when injured, the system may struggle to keep the room at your desired temperature. As such, it’s working harder, which means higher utility bills.
7) Schedule an annual tune-up with an HVAC professional. A trained HVAC technician can detect most problems before they become major ones. With a cost of around $100 for a routine maintenance call, the benefits will likely outweigh the costs by a considerable margin. A typical tune-up will include various tests to ensure your unit’s internal parts are functioning correctly, as well as a filter check, and a refrigerant charge if needed. Your technician will likely also clear the drain, and clean your unit thoroughly inside and out.

“Air conditioners contain refrigerant, which allows the system to run efficiently, releasing heat from the air to cool it. Air conditioners are charged with refrigerant upon installation; a poor charge or a refrigerant leak can cause the system’s refrigerant level to fall below the proper amount. To remedy this, the home AC repair which is performed is a refrigerant recharge, accompanied by fixing the leak if that was the source causing low refrigerant levels.
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!
Eventually, every homeowner experiences a malfunction in their heating unit. It’s a cold morning and you hike the thermostat up like you usually do to take the chill off, but you get no response. You don’t hear the system firing up or feel the radiators or air vents producing any heat. You hope it’s just a quick fix, like a clogged filter or a tripped circuit breaker. On the other hand, you might be wondering if it’s more cost-effective to just have the unit replaced.
In the UK, the Ozone Regulations[62] 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.
Natural ventilation is a key factor in reducing the spread of airborne illnesses such as tuberculosis, the common cold, influenza and meningitis. Opening doors, windows, and using ceiling fans are all ways to maximize natural ventilation and reduce the risk of airborne contagion. Natural ventilation requires little maintenance and is inexpensive.[19]

   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.        
Heaters exist for various types of fuel, including solid fuels, liquids, and gases. Another type of heat source is electricity, normally heating ribbons composed of high resistance wire (see Nichrome). This principle is also used for baseboard heaters and portable heaters. Electrical heaters are often used as backup or supplemental heat for heat pump systems.

Believe it or not, the evaporator coils inside the AHU (Air Handling Unit) are freezing. You may notice the refrigerant lines on the condenser or at the AHU are frozen with ice build-up. The frost or ice builds up on the evaporator coils and blocks air flow (low air flow and no cooling are a sign of a low charge). A low refrigerant charge will cause the evaporator coil to operate at or below freezing. Since the coil typically operates below the dew point, it draws condensation out of the air. When the evaporator coil begins operating below freezing all this condensation freezes to the evaporator coil and the unit stops cooling.

I'll give props to HVAC Service for being available quickly and having Saturday and Sunday appointments. Tony fixed our air conditioner and was professional. So why only 2 stars? Because we sent the receipt into our homeowner association to see if we could get reimbursed for some costs, and the property manager said that we paid THREE times more than we should have. We got conned. I advise you to call HVAC Service, but also shop around and get other estimates. Learn from our mistake!
The condensed, pressurized, and still usually somewhat hot liquid refrigerant is next routed through an expansion valve (often nothing more than a pinhole in the system's copper tubing) where it undergoes an abrupt reduction in pressure. That pressure reduction results in flash evaporation of a part of the liquid refrigerant, greatly lowering its temperature. The cold refrigerant is then routed through the evaporator. A fan blows the interior warm air (which is to be cooled) across the evaporator, causing the liquid part of the cold refrigerant mixture to evaporate as well, further lowering the temperature. The warm air is therefore cooled and is pumped by an exhaust fan/ blower into the room. To complete the refrigeration cycle, the refrigerant vapor is routed back into the compressor. In order for the process to have any efficiency, the cooling/evaporative portion of the system must be separated by some kind of physical barrier from the heating/condensing portion, and each portion must have its own fan to circulate its own "kind" of air (either the hot air or the cool air).
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.

An HVAC service contract can be a very cost-effective way to make sure your system is properly maintained and to have someone on call when things go wrong. Depending on the amount of services offered, they cost between $150 and $500 per year, but they often include yearly inspections of both your furnace and A/C, discounts on major repairs, and preferred scheduling status when you have problems during the busy season. 

Before you service an air conditioner, make sure the unit is turned completely off by unplugging or shutting off the circuit breaker. Then, rake off any debris from the unit and use a soft brush to remove dirt from the outside cover. If the small copper pipe connecting the unit to the house feels hot, the unit’s coils likely needs to be washed. Remove the outside cover, cover the motor and wiring with a plastic sheet, and hose down the fins, coils, and inside of the unit. Finally, replace the cover when you’re done.
Whether you’re starting your air conditioner for the first time this year, or a unit isn’t running properly and you need to service an air conditioner, following a few simple steps can save you time and money. While some service jobs should be left to a professional, there are several do-it-yourself fixes you can do to keep your air conditioner cooling all summer long.

Each spring and fall before you start using your air conditioner, furnace, or other heating and cooling systems, you should get a tune-up to ensure your HVAC system is ready for the season. By spending a little twice a year, you can save a lot in energy bills by keeping your system operating at peak efficiency. You also can avoid costly repairs by identifying and fixing minor problems before they turn into big ones. Plus, many homeowners don't realize that their manufacturer's warranties may be considered invalid if they aren't getting their unit serviced twice a year.
5) Your air conditioner is short cycling. It is perfectly normal for your air conditioner to cycle on and off to maintain a set temperature throughout your home. However, if you notice that it is turning on and off more frequently than usual and the outside temperature is not particularly warmer than normal, it is possible that your unit is malfunctioning. Short cycling puts extra stress on your air conditioner, and can cause it to fail entirely if not handled quickly. 
Changing your central air conditioning unit's air filter at least once every six months will not only help you save on your monthly bills but also will help extend the life of your system. Changing the filter every three months is even better. All the air in your home circulates and recirculates through the same filter attached to your indoor unit. Designed to remove dust particles to keep the air you breathe clean, filters become clogged, causing your air conditioning and heating system to work less efficiently and costing you more to operate it. If left unchanged long enough, your system could fail completely.

Within the construction sector, it is the job of the building services engineer to design and oversee the installation and maintenance of the essential services such as gas, electricity, water, heating and lighting, as well as many others. These all help to make buildings comfortable and healthy places to live and work in. Building Services is part of a sector that has over 51,000 businesses and employs represents 2%-3% of the GDP.


Waited a week for technician who showed up for less than 15 minutes and told me that my air filters were dirty and I needed to experiment with thermostats to be comfortable. Thermostat shows temp at 75 when set on 71. Did what he instructed and still had problems when I realized unit was short cycling. When I called technician he told me I would have to place a new request for service. He gave me the office number and hung up on me. By the time I called office he had called in and said he refused to come back out. The operator would not give me business owners name and could not tell me why technician refused to return although they did say they would refund the fee for service call. Telephone rep yelled at me.

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.

Low refrigerant charges take away from the life of the compressor. The compressor is cooled from the return refrigerant vapor. When there is a low charge there are fewer vapors to cool the compressor, therefore it runs hotter. Any compressor (or electric motor for that matter) which runs above the recommended temperature range will have a shorter life span and cost more to operate.
Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system's filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.

If you believe that the ac not working or you’re getting little or no cold air, check these three things first. Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home. If you’ve changed the filter and opened all the registers and you’re still not getting airflow at the registers, deice the A-coil. Move the thermostat mode switch from “Cooling” to “Off” and move the fan switch from “Auto” to “On.” Let the blower run for at least 30 minutes or until there’s good airflow at the registers. Then turn the AC back on to test it. If it works for the next 12 hours, you’ve solved the problem.
