Questions
- What is the SEER2 rating of the AUX AHU30HPV1BO?
- The AUX AHU30HPV1BO is rated at up to 18.0 SEER2 and 11.6 EER2 for cooling and up to 9.0 HSPF2 for heating. The exact figure depends on the indoor unit it is paired with.
- Is the AUX AHU30HPV1BO good for cold climates?
- Yes. At least one certified matchup meets the ENERGY STAR cold-climate criteria, delivering up to 32,200 BTU/h at 5°F with a COP of 1.82, so it is still 1.8 times as efficient as electric resistance heat at that temperature.
- How much does the AUX AHU30HPV1BO cost to run per year?
- At its rated efficiency it costs about $786-$2,274 a year in electricity in large U.S. cities, depending on climate and local rates - for example $993 in Phoenix and $1,918 in Minneapolis. The calculator on this page works it out for your city and compares it with your current system.
- Is the AUX AHU30HPV1BO the same as the HAVELLS GHO30H52ACXL05?
- Yes, as far as the certified ratings go. ENERGY STAR lists both model numbers with identical efficiency, capacity and matchups, which means the same outdoor unit sold under a different brand or with a minor variant code (voltage, colour or region). The full list is on this page.
- Which indoor units work with the AUX AHU30HPV1BO?
- ENERGY STAR lists 1 certified combination for this outdoor unit. The highest-rated one uses AHU30HPV1BI.
- What refrigerant does the AUX AHU30HPV1BO use?
