The HVAC industry has grown a lot since Brennan’s Heating & Air Conditioning opened. Today, high-tech comfort systems require highly-trained technicians who are NATE-certified and experienced in all areas of air conditioning repair, heating, and indoor air quality. After 35+ years, we’ve changed a lot too. At Brennan’s Heating & Air Conditioning, we still provide good, old-fashioned service, but we also offer the full line of cutting-edge products from the heating and cooling experts at Carrier.

The Environmental Protection Agency (EPA) requires that all technicians who open a system containing a controlled refrigerant be certified to do so. There are four levels of certification, one of which is a “universal” certification to allow the HVAC technician to work on any type of equipment containing refrigerant. Your HVAC technician should be certified as “Level II Certified” at a minimum or, preferably, “Universal Certification” to work on your central air conditioner. Obtaining this certification information from your professional HVAC technician may be required in the event you are working with a realtor to sell your home. Costs for certification average $40-$240.

ISO 16813:2006 is one of the ISO building environment standards.[27] It establishes the general principles of building environment design. It takes into account the need to provide a healthy indoor environment for the occupants as well as the need to protect the environment for future generations and promote collaboration among the various parties involved in building environmental design for sustainability. ISO16813 is applicable to new construction and the retrofit of existing buildings.[28]
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.

Outside of your home is an outdoor unit, which is called a condenser. Inside the condenser is a compressor, a condenser coil, and a large fan. The compressor pumps cool refrigerant to an evaporator coil located either in the air handler or just outside the furnace. The evaporator coil gets really cold so that when the blower or furnace pushes warm air past it, the air is cooled. This cool air is then distributed throughout your home through a series of air ducts. Heat is absorbed by the evaporator coil, which warms the refrigerant moving through the coils. This warm refrigerant is then pumped back outside to the condenser coil, where a giant fan cools it off allowing the warm air to escape. This cycle is repeated until your thermostat detects that your home has reached the temperature you set it to.
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.

“Robinson Air = top notch professionals. Mike was personable, knowledgeable, timely, thorough, and left me with a hard copy of prioritized recommendations and his explanations of HVAC needs I may have in the future. I was very impressed with being shown a tablet picture of a possible problem. It was so refreshing to have the service and all phone interactions handled so well and smoothly…thank you for taking the “angst” out of this kind of service call. My hat is off to you and I will happily recommend you to family and friends. Thank you!!!”


Focus first on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter. Next, look to seal any other ducts that you can access in the heated or cooled part of the house. See our Duct Sealing Fact Sheet (787KB) for more information.

HVAC professionals in the US can receive training through formal training institutions, where most earn associate degrees. Training for HVAC technicians includes classroom lectures and hands-on tasks, and can be followed by an apprenticeship wherein the recent graduate works alongside a professional HVAC technician for a temporary period.[29] HVAC techs who have been trained can also be certified in areas such as air conditioning, heat pumps, gas heating, and commercial refrigeration.[30]
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.
Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage so that the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat-exchanger-equipped boreholes. Some systems with small storages are hybrids, using free cooling early in the cooling season, and later employing a heat pump to chill the circulation coming from the storage. The heat pump is added-in because the storage acts as a heat sink when the system is in cooling (as opposed to charging) mode, causing the temperature to gradually increase during the cooling season.
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.
Compare replacement and repair costs: A new boiler or furnace is a substantial investment, but repair costs can also become costly as well. Not to mention, there’s always the possibility of the same issue occurring again or the need for more work in the future. You may want to replace your heating system if the repairs exceed half of the replacement costs.
Change the filters regularly: This is one of the most important steps in system maintenance. Dirty filters mean your system has to work harder to move the air, causing poor performance and creating more wear and tear on the system. A clean filter also lowers your energy costs, since the system uses less power to do the same amount of work, and improves indoor air quality.

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.
The summers here in Alexandria can range from almost pleasant to downright brutal. And you know as well as we do that it’s those latter days when your central AC or heat pump will decide to go down! But you needn’t seek solace at the Waterfront or over at Cameron Run Regional Park. The secret to restoring your comfort lies with the certified specialists at HVAC Unlimited!
Replacing your old heating and cooling equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed. In fact, improper installation can reduce system efficiency by up to 30 percent - costing you more on your utility bills and possibly shortening the equipment's life. Learn more.

Though Harrison had commercial success establishing a second ice company back in Sydney in 1860, he later entered the debate over how to compete against the American advantage of ice-refrigerated beef sales to the United Kingdom. He wrote: "Fresh meat frozen and packed as if for a voyage, so that the refrigerating process may be continued for any required period", and in 1873 prepared the sailing ship Norfolk for an experimental beef shipment to the United Kingdom. His choice of a cold room system instead of installing a refrigeration system upon the ship itself proved disastrous when the ice was consumed faster than expected.[citation needed]
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.

An air conditioner’s cooling process produces condensation, which normally flows away from the equipment, causing no problem. If there is a clog in the condensate drain lines or drip pan, or if outdoor humidity levels are high, moisture may back up into your air conditioner. Excess condensation will increase indoor humidity levels and hinder the air conditioner’s performance. It could also cause damage to your air conditioner’s components.
This doesn't mean air conditioning isn't right for your home. Some people are more sensitive to heat than others. Even if you can't justify the expense of central air conditioning, window air conditioning units will allow you to cool individual rooms tailored for your needs. If you work from home, you may want to put one of these units in your home office. If you have trouble sleeping with even modestly warm temperatures, you may want to put one in your bedroom. If you love to cook and spend long afternoons using the oven, your kitchen may be the place.

If your air conditioner isn’t cooling, or is experiencing another performance issue, shut it off. Don’t continue to operate a malfunctioning air conditioner, as that may worsen the problem at hand. This is one reason we do preventative maintenance checks pre-season – a technician identifies and corrects problems, so you don’t run your system with faulty components, causing more damage.

The heat-exchanger cools the air that is being forced through it by the furnace blower. As the warm air comes in contact with this cool surface the water in the air condenses. By pulling the water molecules from the air. According to the psychometric chart[42] as relative humidity decreases in order to feel cool you will have to lower the temperature even more. A common way to counteract this effect is by installing a whole-home humidifier.[43] Similarly, installing a high efficient system this need to turn the temperature down wont have such and influence on your energy costs.

If your AC doesn’t turn off when room temperature reaches the temperature set on the thermostat, the problem is generally occurring either at the thermostat or in the electrical system that runs the outside condensing unit. You can use the AC’s circuit breaker to shut off the unit, but that should not be a permanent solution—circuit breakers are not designed to be used like light switches.

As you would expect, air conditioning in Portland isn't as expensive as in most areas of the country, owing simply to the fact that most homes don't require particularly large or state-of-the-art units. While our data suggests the national average for air conditioning installation is about $6,000, in Portland we see numbers between $3,000-$4,000, although we've also seen projects as low as $1,500 and as high as $6,000. Heat pump installation is likely to be closer to the national average, but as mentioned, these devices work to be cool your home in the summer and heat in the winter.

The woman answering the phone told me that she would call the technician and call me back with a service window of when he would be there.  Hours later, she still hadn't called back. When I called back to follow up, the new lady answering the phone told me the original woman had given me miss information. They were a call center and could only text the technician (who of course was supposed to be hadn't called me back)! She texted him again and when he finally called back, he told me I'd have to make an appointment for Tuesday! What's the point of after-hours emergency A/C service if I have to wait until three days later and have them come during normal business hours?! Unbelievably poor service! Read more
Advantages of the ductless system include smaller size and flexibility for zoning or heating and cooling individual rooms. The inside wall space required is significantly reduced. Also, the compressor and heat exchanger can be located farther away from the inside space, rather than merely on the other side of the same unit as in a PTAC or window air conditioner. Flexible exterior hoses lead from the outside unit to the interior one(s); these are often enclosed with metal to look like common drainpipes from the roof. In addition, ductless systems offer higher efficiency, reaching above 30 SEER.[39]
