The icing problem becomes much more severe with lower outdoor temperatures, so heat pumps are commonly installed in tandem with a more conventional form of heating, such as a natural gas or oil furnace, which is used instead of the heat pump during harsher winter temperatures. In this case, the heat pump is used efficiently during the milder temperatures, and the system is switched to the conventional heat source when the outdoor temperature is lower.

Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC&R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers).
A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
Other than mineral deposits, the most common problem is sediment in the water supply. The float inlet valve has a tiny hole that easily clogs. The float is usually made of plastic, and if cracked will fill with water and sink. The valve will be stuck open and the reservoir will overflow. Use caution when scraping deposits off the float. If the deposits cannot be removed, replace the float or it will sink and cause an overflow.
Air conditioners improperly installed will develop air duct leaks and low air flow. Your air conditioner looses its cooling power in hot weather. A lack of maintenance will cause your air conditioner to malfunction. Refrigerant charges and compressors are some of the parts needing regular maintenance. Regular maintenance increases the lifespan and production of your air conditioner.

Was not satisifed with this company. This person came out and took 10 minutes only to tell me that my unit would not last for a year and that I needed to have it replaced! I'm not sure if he was very knowlegable or if he was just plain lazy and do not even try to fix the problem. He just wanted to install a brand new system because he was both and of course, that's much more money for him!
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.

Eventually, every homeowner experiences a malfunction in their heating unit. It’s a cold morning and you hike the thermostat up like you usually do to take the chill off, but you get no response. You don’t hear the system firing up or feel the radiators or air vents producing any heat. You hope it’s just a quick fix, like a clogged filter or a tripped circuit breaker. On the other hand, you might be wondering if it’s more cost-effective to just have the unit replaced.
Engineers have pointed out some areas where efficiency of the existing hardware could be improved. For example, the fan blades used to move the air are usually stamped from sheet metal, an economical method of manufacture, but as a result they are not aerodynamically efficient. A well-designed blade could reduce electrical power required to move the air by a third.
Not obvious is the fact that they need maintenance routinely, just like any other machine. The filter, usually located behind the front grill, needs to be washed. The condenser coil at the back of the unit can accumulate a lot of debris, and might require a special chemical bath. All air conditioning systems, large or small, need good air flow across the evaporator coil and the condenser coil. Efficiency and performance drop rapidly as air flow decreases. Lose enough air flow and the unit will burn out. Rodents can nest inside when not in use, and can foul up the unit in many ways. Wasps and hornets, as well as the honey bee find finned coils to be comfortable nesting places. Nests and dead insects can ruin the air conditioner.
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.
Tony from HVAC came out on Sunday morning and did a fantastic job of immediately diagnosing the issue, quickly fixing the problem, and honoring the coupons I had. When I initially called on Saturday morning, I had a lot of trouble with their answering service getting their wires crossed with their technicians. However, Tony called me back and made it right. He even pointed out an issue that is in the horizon that I should look at (without charging me extra or telling me I had to fix it right now). Great service!
If your unit needs more than two pounds or charged more than once a year it is recommended you have a refrigerant leak check done to your system. You most likely have a serious refrigerant leak and it needs to be repaired. Leaking units do not operate efficiently; take their toll on the environment, and can cause serious HVAC mechanical problems in the future. Lastly, a good HVAC service tech will attempt to find the refrigerant leak within the hour’s air conditioning service you are paying for in addition to the refrigerant charge.

You should also have air ducts cleaned after recent water contamination or water damage to prevent mold; after renovations or remodeling to ensure debris and dust didn’t settle in the vents and ducts; if you are having problems with allergies or asthma; or when you are moving into a newly purchased home, especially if the previous owners smoked or had pets. The National Air Duct Cleaners Association (NADCA) recommends getting your air ducts cleaned every three to five years, or every two to three years in regions where homeowners use their air conditioning and heater for many months of the year, while the EPA suggests homeowners have duct cleaning done as needed.
5) Check certifications. Many HVAC professionals belong to the Air Conditioning Contractors of America (ACCA) or the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). Both sites provide listings of HVAC contractors by area. Look for contractors whose technicians are certified by North American Technician Excellence (NATE) and partnered with ENERGY STAR.
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.
"Friendly, professional, responded quickly to my problem. I have called many air conditioning companies about my problem including the maker of the unit and had come to the conclusion that I would not find someone to repair this unit. D's came in and within a short test found the problem and assured me of a fix. They made the fix within 2 days as they needed to get a part and they also checked to see what the cost would be of the fix by putting in the control boarrd from the maker which was very high to the extreme. I now have a unit working and am very pleased."
