When your gas furnace isn’t blowing hot air, the issue could be due to a faulty pilot light or broken ignitor. Remove the furnace cover panel and visually inspect whether you can see a flame from the pilot light. A natural gas furnace will be blue and yellow in color, and a propane furnace should have a bluish green flame with a yellow tip. If you can see a flame and it appears normal, the issue could be related to the furnace blower motor or other complex furnace parts. If the flame appears low or non-existent, it’s best to contact an experienced furnace repair company. Remember to never touch any open wires; contact a professional.
Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor, because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.
An example of a geothermal heat pump that uses a body of water as the heat sink, is the system used by the Trump International Hotel and Tower in Chicago, Illinois. This building is situated on the Chicago River, and uses cold river water by pumping it into a recirculating cooling system, where heat exchangers transfer heat from the building into the water, and then the now-warmed water is pumped back into the Chicago River.[25]
In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify the HVAC systems. Specialty mechanical contractors then fabricate and commission the systems. Building permits and code-compliance inspections of the installations are normally required for all sizes of building.

1) Your air conditioner is not working at all. Before calling in a professional to address this issue, you may want to check a few things yourself. Check to see if your thermostat is set to “cool”. Confirm that your designated cooling temperature is less than the temperature of the room or home. If everything is set correctly, check the electrical panel to be sure you do not have a tripped breaker. If these things all check out and your air condition unit is still not working, it is time to call in a professional.
Air conditioners can create a lot of water because they remove moisture from the air. To get rid of this, they have a [usually plastic] drain pipe that comes out of the side of the air handler. Over time, algae can block this pipe and, when it does, the AC won’t work. In fact, some condensate drains have a float switch that won’t let the AC run if water backs-up. Water can also puddle around the unit or flood the area. To deal with condensate problems, please see Air Conditioner Leaks Water, below.
Recent Review: Metro Service was amazing. They came out on Saturday and secured the gas to a failing furnace to insure our safety. They came out on Monday and had the new furnace installed and operating within less than 4 hours. Polite, professional, meticulous and 35% lower than their competitors. I will be using them for all of my HVAC needs in the future.

We had an exceptional experience with Gator Air, in particular Carlos. He presented us with quotes for different types of AC units, told us facts about said units and left us to make our decision. No high pressure sales. The installers were professional and cleaned up when they were through. A nice surprise was the 1 year free maintenance of the unit. We belonged to the Gator Club so to not have to pay it for the next year was an added bonus. Thank you GatorAir for making the experience an enjoyable one.
Vacuum the fins of your AC unit clean with a soft-bristle brush. Note: they’re fragile and can easily be bent or crushed. On many units you’ll have to unscrew and lift off a metal box to get at them. Check your owner’s manual for directions and lift off the box carefully to avoid bumping the fins. Follow these other steps to safely clean your home air conditioner for better efficiency.
The three major functions of heating, ventilation, and air conditioning are interrelated, especially with the need to provide thermal comfort and acceptable indoor air quality within reasonable installation, operation, and maintenance costs. HVAC systems can be used in both domestic and commercial environments. HVAC systems can provide ventilation, and maintain pressure relationships between spaces. The means of air delivery and removal from spaces is known as room air distribution.[3]

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]

The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window. This process also made the air more humid, which can be beneficial in a dry desert climate. In ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season.[5]
To keep your furnace in good working order it’s important to have it regularly cleaned. The national average furnace cleaning cost ranges from $60 to $80, though prices can vary greatly based on where you live in the country and what your furnace maintenance includes. An HVAC company may have different rates for different levels of furnace maintenance. For example,one company may offer general furnace maintenance for $79 and advanced maintenance for $138. Another company may offer a 38-point maintenance check for $89 and a 64-point maintenance check for $178. According to Energy.gov, a standard furnace cleaning and maintenance visit can include:
If your home is not heated using forced air, chances are a boiler will make sure you stay warm during cold nights. A hot water system delivers hot water through a network of pipes that run to every room in your house. The heating effect gets maximized through radiators. The most common issues with hot water heating tend to be not be major, but small problems that add up over time. Mineral deposits within the water tank, a pilot light malfunction, or an issue with a radiator itself can require professional repair. On average, you will pay between $183 and $582 for these problems. The exact amount will depend on the exact problem, as described in our boiler repair cost guide.
To be honest, an HVAC technician’s work goes beyond more than installation, maintenance and repair.

Terrible - Explained to tech that we had cold air on heat status. I placed Thermostat on emergency heat and was able to get some heat. I told him TXU had installed a a new thermostat and I think he may have installed it incorrectly but wasn't, sure. He said it would cost us more money if he fixed problem if there was one. He said I could pay for it and get reimbursed from insurance company. When he said it would cost us money I said I would live with it. I plan on calling a reputable repair company. He did not check furnace or temperature of house
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.
We contacted GatorAC and have been pleased through the entire process of the purchase, installation and the daily functioning of the unit. We spoke to Angie to get information about the Trane AC. She arranged for Carlos Garcia to come to the house to determine the unit that would fit our needs. We made the choice between 3 units on Thursday and the unit was installed Friday. The Installation team, Willie Shaw and Gary Barber were the best. When they left everything was done, clean and clear and working great. We would recommend GatorAC for your AC needs.

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]

Gas furnaces and heaters have control shutoffs to prevent gas leaks, but they are not fail-safe. If you smell gas in your house, do not turn any lights on or off, and do not try to shut off the gas leading to the furnace. Get out of the house, leaving the door open, and immediately call the gas company or the fire department to report a leak. Do not re-enter your home.
In very dry climates, evaporative coolers, sometimes referred to as swamp coolers or desert coolers, are popular for improving coolness during hot weather. An evaporative cooler is a device that draws outside air through a wet pad, such as a large sponge soaked with water. The sensible heat of the incoming air, as measured by a dry bulb thermometer, is reduced. The temperature of the incoming air is reduced, but it is also more humid, so the total heat (sensible heat plus latent heat) is unchanged. Some of the sensible heat of the entering air is converted to latent heat by the evaporation of water in the wet cooler pads. If the entering air is dry enough, the results can be quite substantial.
In hot weather, air conditioning can prevent heat stroke, dehydration from excessive sweating and other problems related to hyperthermia. Heat waves are the most lethal type of weather phenomenon in developed countries. Air conditioning (including filtration, humidification, cooling and disinfection) can be used to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where proper atmosphere is critical to patient safety and well-being. It is sometimes recommended for home use by people with allergies.

Your HVAC professional can perform a yearly tune-up of your system for around $80-$100. This yearly maintenance can go far toward heading off major repairs to your system and provide you with peace of mind and considerable savings in the long term. Additionally, regular servicing of your AC unit can help a home inspector to certify that your unit is working properly in the event you decide to sell your home.

A number of other variables can influence your decision on whether to repair or replace your furnace, as well. In addition to cost and brand, consider the expected lifetime of your furnace. If it is more than 15 years old, it might make more sense to invest in a new unit even if it costs more than simply repairing the current problem. Long-term costs also play into the equation. For example, your new furnace may be more energy efficient than the current unit. Even though you will pay more for the actual installation, you might be able to make back your investment through lower energy bills. To make your decision, consult with a reliable professional on what to do. In inspecting your furnace, they will be able to make an informed recommendation that looks not just to the next year, but years into the future. That way, you can make the best possible decision for your home and budget long-term.

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 if not handled quickly.

On average, furnace repair costs $287 nationally, with some homeowners spending as little as $60 while others paying $900 for furnace maintenance. Repairs to an electric furnace can run you $300 or less, while gas furnace repairs can be more complex and range from $375 to $1,200, depending on the what needs service. Most homeowners spend between $131 and $454 to fix their furnace. Here is what you need to know, along with the various factors that could affect the price of your furnace repair.

In a thermodynamically closed system, any power dissipated into the system that is being maintained at a set temperature (which is a standard mode of operation for modern air conditioners) requires that the rate of energy removal by the air conditioner increase. This increase has the effect that, for each unit of energy input into the system (say to power a light bulb in the closed system), the air conditioner removes that energy.[30] To do so, the air conditioner must increase its power consumption by the inverse of its "efficiency" (coefficient of performance) times the amount of power dissipated into the system. As an example, assume that inside the closed system a 100 W heating element is activated, and the air conditioner has a coefficient of performance of 200%. The air conditioner's power consumption will increase by 50 W to compensate for this, thus making the 100 W heating element cost a total of 150 W of power.


In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York.[citation needed] After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.[citation needed]
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.
Because an air conditioner moves heat between the indoor coil and the outdoor coil, both must be kept clean. This means that, in addition to replacing the air filter at the evaporator coil, it is also necessary to regularly clean the condenser coil. Failure to keep the condenser clean will eventually result in harm to the compressor, because the condenser coil is responsible for discharging both the indoor heat (as picked up by the evaporator) and the heat generated by the electric motor driving the compressor.
As touched on by their name, heat pumps function by transferring heat energy indoors during the winter and outdoors from your home during the summer. They're often attached to air conditioning units, using the surrounding air to transfer energy. However, geothermal heat pumps and water source heat pumps are also available. The cost to repair a heat pump, again, depends on the specific problem. Replacing a faulty thermostat may cost up to $300 including labor, while a worn or damaged defrost control board can set you back up to $600. For more details on your potential repair costs using this heating source, visit our heat pump repair cost guide.
Your HVAC professional can also help you verify that your system is properly matched by providing you with an AHRI Certificate of Certified Product Performance upon request. The certificate verifies that the outdoor unit (condenser) and the indoor unit (evaporator) combination has been certified as a matched system by the Air Conditioning, Heating and Refrigeration Institute (AHRI). For higher efficiency systems, this certification may help you obtain a rebate from your utility or local municipality if you have to replace your unit in whole or in part. Not all areas offer a rebate, but your technician will likely be able to provide information about the certification process. Fees for performing this certification vary, but generally are relatively inexpensive.
