Rockford Air Conditioner Replacement

System replacement estimates are free as long as we do not have to diagnose your old system first. We offer expert air conditioning system replacement with a NATE certified lead installer overseeing every job from start to finish. We either replace the existing refrigerant lines or flush them with dry nitrogen.

This practice is vital to the longevity of your new system because the alkyl benzene oil used in your old R-22 system is not compatible with the r410a refrigerant used in new AC and heat pump systems. We also flow dry nitrogen through the refrigerant pipes while making brazed connections. Please watch our video on the subject to see why this is important.

Rockford Air conditioning FAQ

Q My air conditioner periodically needs to have refrigerant (freon) added. Is this normal.

A No, it is not normal. If you periodically need refrigerant added, your air conditioner, has a leak.

Q I had an air conditioning contractor tell me that freon could not legally be added to my air conditioner, and I need a new air conditioner or an expensive leak repair. Is this really the law?

A Customers have related to us that a competitor has advised them of this misinformation. The truth is that EPA regulation only applies to very large commercial equipment. There is no such law concerning residential air conditioners. In the case of lager refrigerant leaks, Singer Heating and Cooling recommends repair or replacement of the system. We just want you to make an informed decision.

Q My Air conditioner is over 5 years old. Do I have the older freon (r-22) in it?

A Most air conditioners made prior to 2010 run on r-22 which was replaced by r-410a in 2010. Some air conditioners made prior to 2010 have r-401a as well.

Q Why has the older freon (r-22) become so expensive lately?

A The EPA started phasing out r-22 in 2010 and the phase out will be complete by 2020. Each year the allocation of r-22 (what is allowed to be produced) is reduced from the previous year. In October of 2014 the EPA announced that there will be a 57% reduction in the r-22 allocation in 2015 from what was allocated in 2014. The cost of r-22 went up immediately after that announcement and is expected go up again as the Summer of 2015 nears.

Q are there alternatives to r-22 for my older AC?

A Yes there are several. All of them require, at the very least, the complete recovery of r-22, replacement of the liquid line filter dryer and certain seals, as well as a complete system evacuation prior to adding the new refrigerant. It is against federal law to mix alternative refrigerants with r-22.

Q What temperature should I set my thermostat to?

A We recommend setting your thermostat to the warmest temperature at which you are comfortable. As a rule, raising the thermostat setting just two degrees will reduce cooling costs by five percent. If you are going to be away from home for 8 hours or more, consider raising the set point a few degrees. Do not raise the set point too hi as your system may take a long time to pull the temp down to a comfortable level. A wi-fi thermostat will allow you to control your thermostat from a computer or smart phone. This can be of great benefit for people on an irregular scheduled.

Q My air conditioner is not cooling well. What should I check before calling for service?

A First make sure that the thermostat is in the cooling mode and that the set point is is a comfortable temperature. Make sure that your air filter is clean. Make sure that you do not have a tripped CB. If none of the above appears to be the problem, please call us.

Q My air conditioner is freezing up. What causes this?

A Freeze ups can be caused by: dirty air filters, dirty evaporator coils, low refrigerant (freon) charge, refrigeration restriction, poor duct design, an inoperable indoor fan, incorrect indoor fan speed setting, or and combination of these conditions.

Q How often should I have a professional service my air conditioner?

A Any time that it is making usual noises, is not maintain a reasonable thermostat set point, or your utility bill is higher than normal for the weather conditions. In addition, most manufactures recommend that air conditioners have a preventive maintenance service once a year. It is best to have the air conditioner preventive maintenance service preformed at an outdoor temperature above 75 degrees F. This is because it is difficult to accurately analyze system performance in low ambient conditions.

A Does Singer Heating and Cooling offer service agreements?

Q No. Most service agreements are gimmicks designed to lock in customers. We retain customers by simply providing quality service at a fair price as it is needed.

Q What is EER

A (EER) The Energy Efficiency Ratio of a particular air conditioner/heat pump is the ratio of output cooling energy (in BTUH) to input electrical energy (in KWH) calculated using a 95 °F outside temp and an return air temp of 80 °F and 50% relative humidity. It is the best available metric to determine the efficiency of an air conditioner on a very hot sunny summer day when loads are the greatest. Historically many utilities have choose EER ratings to base rebate qualifications on rather than SEER.

Q What is SEER?

A (SEER) Seasonal Energy Efficiency Ratio, is also a ratio of output cooling energy (in BTUH) to input electrical energy (in KWH), based on a return air temp of 80 °F and 50% relative humidity, BUT the outdoor conditions are varied mimic a fictional cooling season as follows in percent of run time used for the rating.

67F (21.4%)
72F (23.1%)
77F (21.6%)
82F (16.1%)
87F (10.4%)
92F (5.2%)
97F (1.8%)
102F (.4%)

Total = 100%

Note that 66.1% of the conditions are at 77 degrees or cooler when not a lot of energy is going to be consumed for cooling. Often times lower rated SEER equipment will have higher rated EER. To make things even more complicated the AHRI test conditions for SEER/EER ratings do not account for the blower load that is typical in nearly all field installed applications.

Q Hi SEER rated systems will cost less to operate than a base model.

A In many cases the return on investment is not very favorable due to the higher up front costs. On the other hand, an often overlooked advantage of a higher end system, is enhanced comfort. Deluxe systems tend to be quieter, dehumidify better and have less temperature swings between off cycles. As you can see overall cost is not the only factor.

A Should I buy a hi SEER system or stick with the basic standard SEER rating?

Q Hi SEER rated systems will cost less to operate than a base model. In many cases the return on investment is not very favorable due to the higher up front costs. On the other hand, an often overlooked advantage of a higher end system, is enhanced comfort. Deluxe systems tend to be quieter, dehumidify better and have less temperature swings between off cycles. As you can see overall cost is not the only factor.

Q Should I set my thermostat to run the indoor fan continuously (fan on)?

A In most case no. During the cooling season, running the fan in the off ac off cycle will re-evaporate water from the evaporator coil and raise the humidity in your home. This is undesirable in our East Tennessee climate. The indoor fan uses a significant amount of energy (this is less true with ECM motors on hi SEER systems). The exception is in the case of a bi level home with one system that is not zone controlled. In this case the benefit of balancing out hot and cold spots can be worth the trade off.

Q What is the typical life expectancy of an air conditioner?

A The average lifespan for an air conditioner is 10 to 15 years. Some air conditioners last up to 20 years or longer, but that would be exceptional.

Q What should I know about new system warranties?

A Most residential heating and cooling equipment, regardless of brand, comes with a minimum of a base 5 year part warranty and a 1 year labor warranty. In most cases, if the equipment is registered on line, the part warranty extends to 10 years at no additional cost. Extended (at extra cost) warranties extend the labor from 1 year though the the 10th year. In many cases the extended warranties cover, diagnostic fees, trip fees, refrigerant and materials that the base part warranties do not cover.

Q Who administers new equipment warranties?

A The part warranty is generally though the manufacture. The standard 1 year labor warranty is primarily though your installer. The extended labor warranties vary from manufacture to manufacture. At the time of this writing, York and Goodman extended warranties are administered by the manufacture. To the best of our knowledge, all other brands have extended warranties administered though third parties (insurance companies). Singer heating and Cooling believes that warranties administered though the respective manufacture are superior to third party warranties. This is because insurance companies have no interest in your satisfaction with you AC system, but they do have an interest in keeping their cost down by turning down claims. Equipment manufactures have an interest in your satisfaction with their brand.
