    So this is your first sighting of this unit? Who was servicing it before you got tapped? I'm always suspicious of new accounts who drift into the line-up with museum vintage equipment. I somehow...

    I agree. A 34-year old unit is probably at best an 8.5-SEER unit and could easily be even lower than that. Even a 13-SEER system will improve the operational efficiency enough to make the 13-SEER...

    I think you're apt to find a lot of "cross pollination" of work these days. Many companies are recognizing their slow times of year and trying to compensate by introducing new services that others ...

    You can quickly weed out those using short-cuts simply by observing or asking before hand if they're doing a ACCA Manual J-8 load calculation. If not, keep searching. In a vast majority of instances,...

    The factory amount of charge is listed on the condenser data plate. That generally allows for 25-feet of refrigerant line and attachment to the smallest coil that would be a match for the condensing...

    Yes, we've all been burned a time or two. Had a president of a large local distributor ask me to install mini-splits in a friend's house. Did the load analysis, speced out the equipment, which was...

    The first consideration I'd make would be where the treated/non-treated barriers are located. For example, if you're using fiberglass bats as insulation located in the ceiling of the upper floor,...

    Hmmm. Not the type of situation that can be diagnosed over the telephone. What I can state from far away is that there are two things leading to a frozen coil. First is low airflow and the second is...

    Anything can be done for a price. Where the leak is located could be key to the wisdom of repairing or replacing. Is this the indoor coil or the outdoor coil? And BTB, there is no 4.5-Ton system....

    You didn't include any information as to your location. There are many factors that affect efficiency but chief among them is proper sizing of the equipment. A proper load analysis, followed by a...

    Well first, we don't know in what fashion the TXV failed, or if it failed. Absent additional technical info, it's very difficult to provide specific answers. You state one of the copper lines (you...

    Hmmm. Putting a little spin on your question, would buying the components for a new car on line and having a local auto mechanic build it make sense? I doubt you'll find a true pro on this site that...

    I would not recommend a second humidifier on the system. Too much by-pass air can have a very detrimental affect on the other components in the system. A better idea is to cut down on the air...

    There are some issues here that need clarification. Carrier/Bryant units had two entirely different compressors on their 16/18 SEER units. The 16-SEER requires the compressor to stop and restart to...

    IMO, the Greenspeed is best. There are two ways to size the equipment however. Option 1. is to size for the cooling load and enjoy superior dehumidification in summer due to the ramping down of the...

    It wasn't the negative uneed to vent the unit so much as the pipe heated up so quickly it allowed the minimal pressure of the 80% furnace inducer to do the job. Once the vent had to be replaced, it...
