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.
Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.
You can keep your air conditioner running efficiently with some preventative care measures. Shut off the power to your AC before cleaning it or performing any of these tasks: clean your filter at least twice a year; remove leaves and twigs from cages; clean the fins with a garden hose or special spray, then use a butter knife to straighten any that are crooked; keep your yard clean so the fins won't get blocked; cover the unit up for winter; and make sure it's level or you run the risk of damaging the inner workings of the unit.
Refrigeration air conditioning equipment usually reduces the absolute humidity of the air processed by the system. The relatively cold (below the dewpoint) evaporator coil condenses water vapor from the processed air, much like an ice-cold drink will condense water on the outside of a glass. Therefore, water vapor is removed from the cooled air and the relative humidity in the room is lowered. The water is usually sent to a drain or may simply drip onto the ground outdoors. The heat is rejected by the condenser which is located outside of room to be cooled.
We moved into a new home and had issues with the heating ducts in one of the rooms. We called HVAC based on other yelp reviews. Overall, everyone we dealt with were friendly, professional and knowledgeable: From the people on the phone managing the schedule to the those performing the work in our house. The day before the scheduled work we asked if additional work could be done (clothes dryer duct cleaning), which they were able to accommodate. The people working at the house were on time, very polite, took great care to keep the house clean during the entire job and explained everything when they were finished. I will certainly use HVAC again.
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.
Waiting or performing repairs yourself could cause further damage to your system, resulting in more expensive repairs. If you suspect a problem with your air conditioner, schedule an appointment with a licensed, trained HVAC technician at Service Professor right away. When it comes to safe and reliable electrical service and repair, leave it to the friendly, skilled electricians at Service Professor. Your Satisfaction is 100% Guaranteed!
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.
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.
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.
If so, you may want to consider replacing your entire AC system. After your AC system reaches a certain age, it makes more sense to invest in a new AC system altogether rather than repairing it one piece at a time. To learn more about John Moore’s AC replacement program, our warranty, and the cost-advantages of replacing your AC system, visit our AC Replacement page.
Beyond changing the air filter on a regular basis, one of the best ways to ensure your home's HVAC system is operating at peak efficiency is to have a qualified professional HVAC contractor tune up the system on a biannual basis. Energy Star recommends scheduling your system tune-up around the beginning of daylight savings time in the fall and its end in the spring. It's an easy way to remember to have your system serviced before the peak heating and cooling seasons. A standard tune-up is likely to cost you between $70 and $100, but it's money well spent.
Here’s a simple test to try on your own: When it’s hotter than 80 degrees outside, turn on your AC unit, and set it to well below room temperature. Let it run for 15 minutes, then use a thermometer to check just outside the return duct (the area where air flows in to be cooled). Now take a temperature reading just outside the strongest, most easily accessible vent (where cool air should be flowing out). Subtract the second reading from the first. If the difference between these two is fewer than 14 degrees, your HVAC unit might need work.

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.
Should you experience a system breakdown, know that there are a few common causes of summer AC repairs. Below you’ll find a few of the most common ones AC repair technicians face each day throughout the warmer months. Having a better understanding of the troubles your system may face can help you feel more at ease with the AC repair process, and better comprehend the information given to you by your technician.
Change your air filter. Air filters need changed every 30 to 90 days, depending on the type of filter you have. It’s a wise idea to get on a regular schedule – note filter changes on your calendar, and make a note to check them every month during the summer, when your system runs ‘round the clock. Follow these filter change instructions to get the job done.

Air conditioning units work by using evaporator and condenser coils to remove heat from the air in your home. Warm household air blows through the evaporator coils, which transfer the heat into refrigerant vapor, which is then moved to the condenser in the outdoor part of the unit. The condenser coils turn the now-warm refrigerant vapor into liquid, allowing the heat to be dispersed outside and away from your home.
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.
If your air ducts have been damaged, you’ll need to replace them. The national average air duct replacement cost is $150-$280, which may not include materials. Factors such as duct material, labor, location of ducts and linear feet of ductwork will all affect your final costs. Labor costs will vary based on how accessible the ducts are and what material your ducts are made of. The least expensive duct material is a flexible, non-metallic ducting that costs approximately $1-$2 per linear foot. Flexible aluminum is generally more expensive and stronger than non-metallic ducting. Stainless steel ducting is the strongest, the least flexible (meaning installing it typically has higher labor rates), and usually the most expensive. An average price for air duct replacement could range between $35 and $55 per linear foot, including basic materials and labor. A typical single-family home has 6-10 duct runs; replacing or installing one duct run could average $150-$250 for labor.
In 1906, Stuart W. Cramer of Charlotte was exploring ways to add moisture to the air in his textile mill. Cramer coined the term "air conditioning", using it in a patent claim he filed that year as an analogue to "water conditioning", then a well-known process for making textiles easier to process. He combined moisture with ventilation to "condition" and change the air in the factories, controlling the humidity so necessary in textile plants. Willis Carrier adopted the term and incorporated it into the name of his company.

Regardless of the scope of your project, find out what you need to do to prepare your home for their visit. For example, the HVAC professional will need access to the areas in question and may need access to other mechanical or ventilation points. Make sure pets and children are kept out of the way. Ask if your project will involve removing dry wall or making any other structural changes – you may need to hire a professional drywall contractor to patch up HVAC work. If you are adding a unit that may contribute to carbon monoxide within the home, find out if you need to purchase a carbon monoxide detector.
HVAC professionals attend to a home's thermal needs as well as air quality. Because of the technical aspects of HVAC work, find out the scope of work your professional can perform. You may only need your heating unit serviced however, if this professional also specializes in energy efficiency, mold assessment, or offer ways for you to save on energy costs, you may want to hire them for future projects. Because some equipment is gas-powered, your professional should be able to answer questions about installing gas lines and permitting.
5) Adjust your thermostat. If you are away for large stretches of time every day, adjust your thermostat to a higher temperature for the time you are away. This will lessen the amount of time your unit has to work each day, and will lengthen its life cycle. An additional benefit will be a lower utility bill each month. Some newer thermostats allow you to pre-program your thermostat to match your schedule so that your home will still be cool when you arrive. Optimizing your system’s usage will maximize its life in the long term.

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.
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.

Before you reach out to local HVAC companies, jot down a few notes. Know the model of your unit and see if it’s under warranty. If so, call the manufacturer first. Then, get multiple quotes for the project in question. Never get less than two quotes for any home remodeling project. Once received, compare all and make sure all include the same work. Check referrals and certifications before making a final decision.
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.
Your home’s HVAC system is a fine-tuned piece of machinery. Like your car, your system needs regular maintenance and tune-ups to ensure it is running reliably. Manufacturer warranties for most new systems require annual tune-ups, and for good reason: these preventative maintenance measures extend the life of your system by keeping your system running the way it is designed to run.

Got to say that I am very pleased with their work. The knowledge of the technician was on the spot. She was very professional at all times sharing her expertise and advice with me. Going further, I have hired some other pro's from this website to fix my AC and none them identified a faulty connection on the AC blower control board as my technician from Superior AC did. The price for the repair was fair, no overpricing at all. I am pretty sure that I will call them again and definitively recommend them. Thanks!! Aurelio
