The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one. 

Air conditioner equipment power in the U.S. is often described in terms of "tons of refrigeration", with each approximately equal to the cooling power of one short ton (2000 pounds or 907 kilograms) of ice melting in a 24-hour period. The value is defined as 12,000 BTU per hour, or 3517 watts.[32] Residential central air systems are usually from 1 to 5 tons (3.5 to 18 kW) in capacity.
Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls.
An annual inspection of your unit can ensure that the various potential problems mentioned above are detected early, and before they require complete replacement. During this inspection, for instance, a professional might find small cracks in your heat exchanger or a faulty seal in your blower motor. Some manufacturer's warranties even require these annual inspections to maintain validity. Typically, your furnace inspection will cost between $80 and $150 depending on the area in which you live and the professional you work with.
1) Change your filter. The simplest and most effective way to keep your AC running smoothly is changing your filter once a month. By regularly changing your filter, you reduce a lot of the burden on your system. A dirty or clogged filter makes your air conditioner work much harder than does a clean filter. Changing your filters regularly is easy on your budget and easy on your system as well. It will lower your utility bill and extend the life of your AC.

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.

Before calling to schedule your appointment, it may be helpful to familiarize yourself with the air conditioning equipment that you have. Make sure you know at least the brand name, the model and the approximate age of the system, as well as any warranties that may be in effect—and read through our AC FAQ to see if any of your symptoms sound familiar.

A programmable thermostat is a must-have in today’s state of AC technology. Programmable thermostats allow you to set temperatures for various times throughout the day and automatically lower the temperature when you most need it to help you save money and manage your cooling without constantly hovering over the dial. In this article, we’ll walk you through installing a programmable thermostat in your home.
Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.    

I was disappointed with the pressure of a tub and shower that were plumbed with 1/2 supply lines (2nd floor). Could be low pressure from the street, but I want to replace with 5/8. Plus, I'd like to have 2 back to back showers, one inside and one outside. So, I had intended to bring a 1 supply to both, then branch up to valves and shower head with 5/8. Finally, I thought pressure from the street was typically 55 to 70 psi and I am concerned if pvc can take that.Any thoughts?
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace are the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, methyl chloride, or propane, that could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon, in 1928. The name is a trademark name owned by DuPont for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. The refrigerant names include a number indicating the molecular composition (e.g., R-11, R-12, R-22, R-134A). The blend most used in direct-expansion home and building comfort cooling is an HCFC known as chlorodifluoromethane (R-22).

Before selecting the installation location of air conditioner, several main factors need to be considered. First of all, the direction of air flow from the indoor units should not fall on the place of rest or work area. Secondly, there should not be any obstacles on the way of the airflow that might prevent it from covering the space of the premises as much as possible. The outdoor unit must also be located in an open space, otherwise the heat from the house will not be effectively discharged outside and the productivity of the entire system will drop sharply. It is highly advisable to install the air conditioner units in easily accessible places, for further maintenance during operation.


A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements which have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at dehumidifying the internal air. Conversely, a humidifier increases the humidity of a building.
If your compressor doesn’t have an overload button and you hear it humming or buzzing, poke a screwdriver or stick down through the top grille and try to spin the fan blades clockwise. If doing this gives the fan enough of a boost to get it going, the unit has a faulty capacitor that must be replaced. See How to Test and Replace an AC Run Capacitor, above.
The performance of vapor compression refrigeration cycles[27] is limited by thermodynamics. These air conditioning and heat pump devices move heat rather than convert it from one form to another, so thermal efficiencies do not appropriately describe the performance of these devices. The Coefficient-of-Performance (COP) measures performance, but this dimensionless measure has not been adopted. Instead, the Energy Efficiency Ratio (EER) has traditionally been used to characterize the performance of many HVAC systems. EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature averages instead of a constant 35 °C (95 °F) outdoor temperature. The current industry minimum SEER rating is 14 SEER.[28]
Some of the things that determine air conditioning capacity in Arizona include, but are not limited to: your area’s unique climate, monsoon humidity, number of windows, their location, and their NFRC rating, ceiling and wall insulation factors, which direction your home is facing, how much heat your appliances produce, how high your ceilings are, if you have a basement, if you have proper attic ventilation, the location of trees on your property, and even the number of people who occupy the home.
Recent Review: Had asked another company to fix furnace. Other company suggested furnace replacement to the tune of 7k. United Mech was a "second quote"; they came, they looked, they agreed the unit was older, and gave both a quote (1000 less) to replace and the suggestion that the part might be the only problem. Chose to fix not replace. Technician was clearly very familiar with repair. Second good experience with this company. First time, inquired about installing a gas stove in my house. They came, reviewed the ways to run the gas line to the kitchen. They told me it possible, explained how and then said was really too expensive to make it worth it. Unusual to have a firm talk a client out of major job. I remembered that and called them when we needed a second opinion.

Natural gas furnaces operate similarly to the above, using a pilot light to ignite the burners and heat up the air. Also similar to propane gas, your average repair costs for a natural gas furnace will range anywhere from $125 for small repairs to $1,200 if you have to replace the entire heat exchanger. The difference between both options is not necessarily the actual furnace, but the type of gas used to burn through it and heat your home. As a result, the repair costs tend to be close to identical.
In variable climates, the system may include a reversing valve that switches from heating in winter to cooling in summer. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. This allows a facility to be heated and cooled by a single piece of equipment by the same means, and with the same hardware.

All consumer and property manager beware of this is not the old frymire anymore. they are under new ownership and with bunch rip-off tech! I am the property manager with a handyman and were unable to get the heat pump furnace relay replaced on time so I gave them another chance to do it base on good experience in previous. however, the tech used old school trick:telling me his truck dont have the relay and need to get the parts then will call me back. lone story short, we end up been charged for 290 for just a relay! and he even quoted us for a bad run capacitor for total 460!! we called them to provide a detail work invoice as usual and they never send to us so we end up to tell landlord that's how it is.. Huge mistake I ever made..don't trust them at all!!

In 1758, Benjamin Franklin and John Hadley, a chemistry professor at Cambridge University, conducted an experiment to explore the principle of evaporation as a means to rapidly cool an object. Franklin and Hadley confirmed that evaporation of highly volatile liquids (such as alcohol and ether) could be used to drive down the temperature of an object past the freezing point of water. They conducted their experiment with the bulb of a mercury thermometer as their object and with a bellows used to speed up the evaporation. They lowered the temperature of the thermometer bulb down to −14 °C (7 °F) while the ambient temperature was 18 °C (64 °F). Franklin noted that, soon after they passed the freezing point of water 0 °C (32 °F), a thin film of ice formed on the surface of the thermometer's bulb and that the ice mass was about 6 mm (1⁄4 in) thick when they stopped the experiment upon reaching −14 °C (7 °F). Franklin concluded: "From this experiment one may see the possibility of freezing a man to death on a warm summer's day."[9]

The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.

To be honest, an HVAC technician’s work goes beyond more than installation, maintenance and repair. Most people are increasingly spending more time inside the home, so indoor air quality, home energy savings and total comfort have become even more important. There are several choices and solutions when it comes to HVAC systems, and our experts will consult with you every step of the way and work with you to achieve your goals.


Whole-house fans have helped cool homes for a century. The basic design is simple: An attic-mounted fan pushes hot air out through attic vents and draws cooler, outside air in through open doors and windows. This rapid air exchange—large fans can purge a house of hot air in two to three minutes—not only removes built-up heat but also creates a pleasant breeze.

Most central air conditioners are connected to a home's forced-air distribution system. Thus, the same motor, blower, and ductwork used for heating are used to distribute cool air from the air conditioning system. When a central air conditioner is operating, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn't cool, the problem is probably in the distribution system.
Without proper ventilation, carbon monoxide can be lethal at concentrations of 1000 ppm (0.1%). However, at several hundred ppm, carbon monoxide exposure induces headaches, fatigue, nausea, and vomiting. Carbon monoxide binds with hemoglobin in the blood, forming carboxyhemoglobin, reducing the blood's ability to transport oxygen. The primary health concerns associated with carbon monoxide exposure are its cardiovascular and neurobehavioral effects. Carbon monoxide can cause atherosclerosis (the hardening of arteries) and can also trigger heart attacks. Neurologically, carbon monoxide exposure reduces hand to eye coordination, vigilance, and continuous performance. It can also affect time discrimination.[15]
When central air conditioning service fails during a heat spell, you may have to wait days for an HVAC repair technician to show up, and you’ll probably pay at least several hundred for the repair. But if you’re comfortable working around electricity and are willing to spend about $50 on parts, you can probably repair your air conditioning service yourself in about two hours and save a lot of money on parts markup and labor.

If a heat exchanger cracks or contains holes, leaks can release carbon monoxide into your home. Carbon monoxide is nearly impossible for humans to detect on their own due to its characteristics of being colorless and odorless. Because of this, it is referred to as “The Silent Killer”. Some symptoms of carbon monoxide poisoning include headache, dizziness, fatigue, nausea and vomiting. It is extremely important to have a HVAC technician perform a furnace inspection annually to prevent problems such as carbon monoxide poisoning. UGI Heating, Cooling & Plumbing offers yearly maintenance packages and service agreements that include yearly maintenance and furnace inspections.
