How to get minimum of 3 identical records with different dates

Question

Hi All,
Below is my query which gives me the data i want but it gives me a same claim number 3 times because those 3 records have HVAC in them but the comments date is different, So i would like to have one row returned with the min(commentdate).
SELECT C.hsclaimnumber,
COMMENTS.hsobjectid ,
COMMENTS.hsnote as Comment,
C.hsdatecreated,s.state_id,
l.hslosstype,
Comments.hsDateCreated AS CommentDate
FROM hs_comments AS COMMENTS
INNER JOIN
hs_claim AS C ON COMMENTS.hsobjectid = C.hsclaimid
inner join
qx_states s on s.pkey = c.hslosslocationstate
inner join
[dbo].[hs_loss_type] l on C.hslosstypeid = l.hslosstypeid
WHERE (COMMENTS.hsnote LIKE '%hvac%') and
year(c.hsdatecreated) in (2014) AND (l.hslosstype = 'All other physical damage' or l.hslosstype ='Lightning (no fire)' or l.hslosstype ='Water')
group by C.hsclaimnumber,
COMMENTS.hsobjectid ,
COMMENTS.hsnote ,
C.hsdatecreated,s.state_id,
l.hslosstype,
Comments.hsDateCreated
order by C.hsclaimnumber
Can someone please help me with this?
Thanks.
