Dichlorodifluoromethane (R-12) was the most common blend used in automobiles in the U.S. until 1994, when most designs changed to R-134A due to the ozone-depleting potential of R-12. R-11 and R-12 are no longer manufactured in the U.S. for this type of application, so the only source for air-conditioning repair purposes is the cleaned and purified gas recovered from other air conditioner systems. Several non-ozone-depleting refrigerants have been developed as alternatives, including R-410A. It was first commercially used by Carrier Corp. under the brand name Puron.
The performance of vapor compression refrigeration cycles 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.

I needed a replacement for my heater. I called Bill Howe and they promptly fitted me into their schedule. The person who arrived, Laurence C. thoroughly tested my furnace and pointed out the problem. I decided to replace it. They arrived on the day to install it. The two men, Jose Gomez and Javier Diaz promptly went to work. They were clean, efficient and respectful of my home. I would gladly recommend Bill Howe for your heating and plumbing needs. They were great!!

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.
Many disconnect blocks contain two cartridge fuses. Check them before you proceed with repairs (Photo 3). A blown fuse is a sign of a failing part inside the condensing unit. So don’t just replace it and think you’ve solved the problem. Instead, replace the parts we show here. Then install new fuses and fire up the unit. If it blows again, call a pro—you’ve got more serious issues.
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.
“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.

Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits. In more complex schemes, warm air is allowed to rise and flow out high building openings to the outside (stack effect), causing cool outside air to be drawn into low building openings. Natural ventilation schemes can use very little energy, but care must be taken to ensure comfort. In warm or humid climates, maintaining thermal comfort solely via natural ventilation might not be possible. Air conditioning systems are used, either as backups or supplements. Air-side economizers also use outside air to condition spaces, but do so using fans, ducts, dampers, and control systems to introduce and distribute cool outdoor air when appropriate.
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.
It costs approximately $35,000.00 to properly stock an HVAC air conditioning and heating service van (not mentioning the cost of the van itself), office overhead including marketing, phone, fax, business licenses, professional licenses, insurance, advertising, marketing, and did I mention advertising and marketing, Employee costs including payroll, insurance (out of control), benefits, etc…………, and ongoing training and HVAC educational requirements to remain knowledgeable, competitive, and to retain HVAC professional licenses.

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.

If you hear clicking that is followed by a hum or buzz, you’re probably hearing the fan motor attempting to start without the boost it needs from the capacitor. You can almost always conclude that the capacitor has failed. Sometimes you can get the compressor fan spinning (clockwise) by pushing it with a thin stick or long screwdriver poked through the grille. But the chances are good that this might work for one cycle, but the capacitor will fail next time the AC goes on. It’s best to replace the capacitor.
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
The selection of indoor units has one restriction - their total power should not exceed the capacity of the outdoor unit. In practice, however, it is very common to see a multi-split system with a total capacity of indoor units greater than the outdoor capacity by at least 20%. However, it is wrong to expect better performance when all indoor units are turned on at the same time, since the total capacity of the whole system is limited by the capacity of the outdoor unit. Simply put, the outdoor unit will distribute all its power to all operating indoor units in such a way that some of the rooms may not have a very comfortable temperature level. However, the calculation of the total power is not simple, since it takes into account not only the nominal power of the units, but also the cooling capacity, heating, dehumidification, humidification, venting, etc.

Not only he explained really well what was going on but he was careful and knowledgeable. I was so relief that not only we trust in BH team but we were lucky that was Mike coming to execute the service.
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.
Heat pumps and electric furnaces usually have steam humidifiers to increase output. They are line voltage powered and must be unplugged or disconnected before servicing to avoid injury. With the exception of some mist type humidifiers, all have a reservoir. Stagnant water sitting in the reservoir during the off season can be a breeding ground for bacteria. Turn the water off and clean the humidifier if possible when heating season has ended.
The main problem when installing a multi-split system is the laying of long refrigerant lines for connecting the external unit to the internal ones. While installing a separate split system, workers try to locate both units opposite to each other, where the length of the line is minimal. Installing a multi-split system creates more difficulties, since some of indoor units can be located far from the outside. The first models of multi-split systems had one common control system that did not allow you to set the air conditioning individually for each room. However, now the market has a wide selection of multi-split systems, in which the functional characteristics of indoor units operate separately from each other.

I'm very glad that I found another guy to come replace the circuit board and put it away from the water, fix the water leak, and also find and fix another impending failure. All of that was for much less than HVAC Service wanted to charge for repair or replacement. The other guy did a great repair, so I'm confident it will not break down again, but if it does, I will not call HVAC Service. Don't get suckered by their Yelp Deal.
One of the easiest maintenance tasks consumers can do themselves is maintaining the filters. Air filters should be inspected and cleaned once a month. This allows for regular monitoring to eventually determine when the filter needs to be replaced. Most filters can be changed every three months if no other problems exist. Maintaining clean and regularly changed filters will not only produce better air quality, but appliances will function more efficiently, which can save on heating and cooling costs.

Since the 1980s, manufacturers of HVAC equipment have been making an effort to make the systems they manufacture more efficient. This was originally driven by rising energy costs, and has more recently been driven by increased awareness of environmental issues. Additionally, improvements to the HVAC system efficiency can also help increase occupant health and productivity. In the US, the EPA has imposed tighter restrictions over the years. There are several methods for making HVAC systems more efficient.
Check that the 240-volt circuit breaker (double-pole breaker) controlling the air-conditioning compressor/condensing unit and the 120-volt circuit breaker controlling the furnace blower or separate air handler, is in the "On" positions. If a circuit breaker has tripped or a fuse is blown, then reset the circuit breaker or replace the fuse. If you reset the breaker or replace the fuse and they trip or blow again, stop and call an air-conditioning service technician, as you may have a more serious problem.
Other workers sometimes help HVACR technicians install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, ductwork may be installed by sheet metal workers, electrical work by electricians, and pipework by plumbers, pipefitters, and steamfitters. Boiler systems are sometimes installed by a boilermaker.

Finding a qualified technician can be as easy as asking family, friends and neighbors for recommendations or consulting online review websites and choosing a service provider that has received a significant number of positive reviews. Consumers must verify that any professional who is hired to do HVAC repair and maintenance has been properly trained and certified. Many service providers list licensing and certification information on their website.Last updated on Jul 11, 2018
